Sony ‘HowTo’ videos – a different level

Posted on By

Paul Genge of Sony UK noted my criticism of the Sony corporate videos. Well, what Sony were not publicizing so well was that Paul has been making some rather homespun but far more valuable and interesting videos – in fact, going beyond the usual remit of Sony staff to do stuff almost off the cuff.

I remember Paul telling me a few years ago that Sony was most cautious about any publicity material, especially its wording. Even short press releases had to be approved by a management meeting and looked over by the lawyers. That is not unusual with large corporations.

It’s also, back in the 1970s to 90s, what made Dick Bryant’s job with Minolta so remarkable – he had a roving brief and an expense account and he could travel pretty much anywhere in the world and publish any set of images he wanted (such as his exceptional treatment of Eugene Smith’s Minimata essay). He may have reported back to Osaka but he certainly had a degree of freedom, creative and fiscal, which very few representatives of corporations seem to have today.

Could Paul convince Sony that uncontrived, honest, genuine enthusiastic reporting and involvement with photographers merited a similar job today? Doing a Dick Bryant?

Here’s one example, Paul with our friend Gustav Kiburg on Inner Farne in July.

What you need to do, though, is visit Paul’s complete SonyHowTo YouTube collection (as I write this I think there are 27 short vids up, varying from wobbly and unpolished to pretty good – all well edited, with excellent use of inset illustrations and still photo examples).

Here’s the link:

http://www.youtube.com/user/SonyHowTo

So far Paul’s channel only has 44 subscribers (Sept 1st, I’ll bet that changes) and if you subscribe you can also ask to be notified by email of new vids. Also, you can chat with Paul on the comments sections, and you can probably request subjects to be covered. I think we should ask for – using the Alpha 99 and 500mm G lens…

Sony – please add gain control to A77 sound

Posted on By

When I had the Canon 60D and 600D cameras for the usual brief period of magazine review loan, one of the things I could have tested more thoroughly was the excellent implementation of sound input gain control. Since it worked, and worked really well, I had no need to. Any system with auto gain, in contrast, needs to be hauled out to big rock music gigs, into busy urban environments, stuck close to the speaker at public events and so on.

This is the screen from the Canon 600D, which is not an expensive camera. Being realistic, it and the 60D with their usefully articulated rear screens and 18 megapixel filesize are more than decent competition from some months ago for the forthcoming Alpha 77. At the moment it seems as if Sony has leapfrogged Canon, but when you actually look at the capabilities of the 60/600 for practical everyday work they remain competitive.

This audio control screen is one of the main reasons why. I read people, Sony users, on forums saying that lack of audio control is quite simply a deal-breaker. And I know why. I am an occasional musician and occasionally my wife will press the MOVIE button on an Alpha or NEX aimed at me. It’s a complete lottery as to whether than button is pressed during a quiet microsecond between notes, in dead silence, with a full PA sound level or whatever. When making a recording using one of these cameras, I will often ask the subject to speak or play a loud chord so that I can press MOVIE and get a low auto mic gain preset. The worst scenario is to press MOVIE in total silence because the auto gain will then try to boost the sound to pick up the birds outside the window and the floorboards creaking. And it will stay on that gain level for the entire take.

What this means in practice is that different takes have different gain levels. It would be even worse if the gain was dynamic during the take, varying with the level so that quiet moments suddenly get rewarded by an increase in hiss and irrelevant noises. There are plenty of camcorder devices which do that and they are unusable.

Auto gain – which applies to both the internal and external mic feeds for the Alpha 77, and also to the NEX models and earlier Alphas – is simply not acceptable as the only option in an age where users like to film concerts and gigs, live music, bands, parades, festivals and noisy events. Small condensor mics are very prone to clipping (distorting loud sounds) in what are known as ‘high sound pressure’ environments. That is, stuff which hurts your ears if you are a dog or under 30.

You can avoid high sound pressure clipping by using a top quality external plug-in mic, as you are never going to eliminate it with the internal mics. But you can only do so reliably if the camera offers manual control of audio level. Nikon’s cameras – even the expensive D3S – only offer three levels of sound gain and no ability to monitor or test the effect. Canon’s latest models have an exemplary interface with 22 visible dB (deciBel) levels and an even finer graded adjustment with a continuous Rec. Level scale. This applies to either the internal (mono, less satisfactory) mic or external stereo.

Although Canon’s official line is that the external mic socket is for mic only, not for line mixers, it is in fact compatible with any good quality line source you can control for volume level. The setup above is just an imaginary studio shot, not real recording, but shows two Behringer condensor mics routed through a Mackie Onyx Satellite twin mic preamp. I used the headphone output, with its controllable volume, to feed the Canon 600D. There did not appear to be any impedance issues but of course I started with the sound output at zero and used the Canon’s manual sound monitor to adjust it.

This is not advanced audio. This is basic home recording stuff. It’s well within the target owner bracket of the Alpha 77. Sony, if Canon can do this, so can you. Even just implementing three manually set High, Normal, Low fixed volume (gain) settings like Nikon would be a partial cure. Nikon’s solution is not total, and I sold my Nikon D5000 because of the terrible clipping which happened on any setting when trying to record amplified solo gigs. Even little 40W solo amps and a simple vocal and guitar would send the Nikon into a crackle of distorted mess. The Sony mics seems to be much better and do not clip so readily. They are stereo and I’d rate the sound quality from the internal mics on NEX and Alpha so far to be much better than Canon’s internal mono (the AVCHD recording standard helps too). But without proper control of sound, the Alpha 77 is hamstrung. It is indeed a deal-breaker for some buyers.

It can be fixed if the firmware allows access to that function.

The video area issue

While you are at it, fix the HD video framing screen marks on some earlier and current models – we hope it has been sorted in the new ones.

It’s simple enough. The Sony CMOS 14 megapixel sensor crops to 16:9 for panoramic shots (you can select yo shoot in this format if you want) and also crop to 16:9 for HD1080 video. But these two crops are not the same. The still 16:9 just trims a bit off the top and bottom of the image. The HD video format trims even more and also takes some off both ends, zooming in (in effect) on an overall sensor crop.

When you shoot normal 3:2 ratio 35mm shape shots, and press the MOVIE button, the resulting crop is so dramatic that you can cut someone’s head off in the movie having thought it was well within the frame for stills.

As you can see in the shot above, the NEX does display some faint corner crop marks to indicate the video frame. But no-one I have shown the camera to actually notices these crops at all, especially if other grids or marking are displayed. Setting the camera to 16:9 stills improves the position, the faint crop marks are now equally distant from all four corners but still unlikely to be clearly visible. It’s clear from forum comments and messages elsewhere that many owners have never spotted these marks at all. The frame corner markings are not easily seen against some subjects (example above, lower marks), and you need to know where they are in order to recognise them.

This issue is not present in the Alpha 55, where the movie is only cropped top and bottom, and slightly bolder frame crop marks are shown in the finder. Even so, two very clear lines which can be turned on or off would be a better indicator and help users frame video correctly before pressing the record button. If you set 16:9 still shooting on the A55, you can go into movie capture without any change to the image framing.

Note that the ends of the composition are cropped, as well as the top and bottom, when pressing MOVIE Record from the startpoint of a 3:2 format still shot on the NEX-3 and NEX-5 with their 14 megapixel sensors. When shooting HD video, note that frame corners for the 4:3 TV format (non-HD crop) are displayed.

In an ideal world, the HD movie would be the full 16:9 still size as on the A55, giving you the best use of wide-angle lenses. But that is probably not possible because of the way HD1080 is extracted from the overall sensor area of the NEX-3/5.

So, what we need is simple enough – a firmware option to display the HD Movie crop area far more distinctly on the EVF or rear LCD screen, whatever still shooting mode is being used. Ideally it should be a complete rectangle to show the actual area which will be active when you press MOVIE and record.

Like the audio control issue, this is a firmware fix and could also be applied to earlier models like the NEX-5. It’s probably a simpler fix than audio.

Of more concern is whether or not the 24 megapixel sensor behaves like the 14 megapixel (HD movies cropped all round) or like the 16 megapixel sensor (HD movies cropped top and bottom only). So far this has not been made clear by early testers or Sony sources. If it is a cropped HD, let’s hope that a very clear and obvious movie-frame preview can be added, or the MOVIE  button function changed so that one press activates the movie frame view, the next press starts record, the next press ends record. I would actually like to see a menu option where ending a recording does not exit movie mode, but leaves you able to press the movie button again to resume filming, and to end movie capture you need instead to press the shutter button (with or without a still capture).

Alpha 55 video of a rare occasion

Posted on By

On Saturday, the Household Cavalry chose to provide a guard of honour for a wedding couple lucky enough to have planned their wedding for the day the mounted regiment was in town. I photographed the event from the unique viewpoint of an Alpha 55 fitted with a Sigma 8-16mm superwide zoom, mounted on a 3.5m high Manfrotto stand with a 7″ Lilliput HDMI monitor connected on a long HDMI cable to compose and follow the action. The sound is just what the camera recorded, no external microphone was used.

Smoke and Mirrors – an idea for Sony

Posted on By

With the latest Alpha 77, Sony has introduced SLT version II, the new upgraded ‘Translucent’ mirror. This is in an attempt to reduce the ghosting effects created by having an angled mirror between the lens and sensor, the image forming rays passing through a semi-silvered (pellicle) surface, through a thickness of polymer film, and then to the sensor. Having tried it out (update, September 8th) we can confirm that it works. You honestly would never know there was anything between the lens and the sensor.

But Sony, like all makers, has continued to think in terms of SLR design and the old world of film negatives and slides, where the image always had to be a certain way up on the film, or it would end up being printed and projected reversed left to right.

In the past a simple reflex mirror for a TLR viewing screen – like the Rolleiflex – did a useful job of turning an inverted image the right way up for viewing. On film at the back of the camera, the image was both inverted and left-to-right. But that did not matter, as the film was viewed through its reverse (back) side to see or print the image.

Somehow, this old design has been continued to new cameras – but today we use digital sensors. The upside-down or left-to-rightness of the image does not matter as we view the image on a screen or using an EVF. No matter how the image ends up on the sensor, it can always be the right way up and the right way round for us to view.

So, Sony, when you make you that full-frame Alpha 99 camera change the entire approach. Position the SLT mirror so it reflects the image sideways, upways or downways! And put the SENSOR where it receives the image from the REFLECTED lightpath. Make the mirror reflect 70% of the light and transmit 30%, instead of the other way round.

There will be no double imaging, no flare patches, no ghosting and not even an extra substrate or layer for the image forming rays to pass through, if the sensor receives the reflected image not the transmitted one. The AF sensor, in the meantime, can be positioned in direct line to the lens where the imaging sensor has been in the past, measuring the image through the SLT mirror.

This arrangement (©David Kilpatrick, Friday morning, August 26th 2011, scrambled eggs with smoked salmon for breakfast) will in a single stroke remove all the complaints about image degradation as the mirror will provide a perfect image.

But – would it? Slight lack of plane perfection in the SLT mirror used to transmit the image-forming light, and reflect the AF-measuring light, does not have much effect on the image. Anything less than an optically perfect mirror would fail to create a quality image. It would be like sticking a cheap filter on your lens, or worse. And of course it would never fit into a normally shaped camera body with a full frame sensor and shutter.

Solid solution

Ah – the AF sensor, unlike the imaging sensor, does not need cleaning to remove dust spots. So the mirror would not have to be movable. Actually, it would not have to be a pellicle mirror. It could be a lovely big lump of pure glass prism moulded straight on to the AF module itself, even including the condensor-collimator lenses of the AF system. It could be solid glass all the way from mirror surface to AF receptor, and the 45° front face could be to the same optical perfection as the best Sony G lens. Or even the best Carl Zeiss lens. Hell, it could be a Carl Zeiss prism and then the camera could have the CZ logo!

Diagram above: light blue = solid glass optical prism with 45 degree semisilvered front face; the two white indents at the right hand side indicate AF modules set into the prism rear face. Pink = shutter (optional, ideal system would have electronic shutter only). Dark blue = sensor. Green = top mounted waist level viewing screen, also articulated. A secondary eye-level EVF would or could be used. Design ©DK with a bit of nicked Sony lens cross-section.

Design? Rollei 6000 all the way! A professional, Hasselbox-shaped thingy to cradle in your hand. With a rotating 24 x 36mm sensor too, so that you change the format aspect by pressing a button not maneouvring the camera body. A 3 inch square OLED on the top like a giant waist-level finder, showing the image vertically or horizontally as you turn the sensor. A waist-level viewing hood for a giant magnified view. Maybe even a monster top prism for the biggest EVF you could imagine!

Mor realistically, an eye-level EVF in addition to a top plate OLED or LCD panel designed to be hinged up/rotated/twisted – rather like the LCD of the Sony Cyber-Shot DCS R-1, one of the best ever ‘waist level finder’ options fitted to a digital camera to date. In fact something like s giant updated R-1 full framer might do well.

As for the image sensor, that could be in the well of the camera (mirror aiming down) but maybe having it in the top of the camera, below the viewing screen (mirror facing up) would help gravity reduce the dust issue.

The point is – it does not matter where the image sensor is placed, it does not have be where the film once was. It does not matter whether the image reaching it is inverted or reflected, as unlike film it does not have an emulsion side or a film-base side, the electronic viewfinder is independent of the orientation of the optical image.

Future ‘SLT’ EVF cameras – especially a future Alpha 900 replacement – do not need even to resemble today’s DSLRs and can be made better by abandoning ideas fixed in designers’ minds since the era of film cameras.

– DK

Technical note: angled partial mirrors, whether prism surface or semi silvered, create polarisation effects, colour shifts and a varying efficiency of reflection depending on the angle of incidence of the ray. This is one barrier to the use of pellicle mirror design for a full-frame model, as the back focus or telecentricity of lenses relative to the format would mean a greater range of incident angles across the mirror surface. Sony appears to have overcome any such problems in the existing APS-C SLT design, and the slightly forward tilt of the mirror (not a true 45°) helps in this respect. I propose the above design in full awareness of related optical and technical issues. I’m not assuming they do not exist – they would need solving.

Sony UK’s live Q&A webcam sesssion

Posted on By

A recording – advance for half an hour or so to miss the lengthy setting-up process – is available of the web Q&A which Paul Genge of Sony handled tonight for a UK and worldwide audience of over 450 web-browsers.

Here are some resumé details and comments made during watching the webcast:

Paul failed to understand the question about the angle of view for video. Some existing models (14 megapixel NEX for example) crop the horizontal angle of view for HD1080, they don’t just take slices off the top and bottom. The question whether the 24.3 megapixel sensor HD mode uses the full horizontal angle like the 16 megapixel Alpha 55 remains unanswered.

Flash sync socket combined with auto gain for manual live view in place of manual mode exposure simulation does allow studio work with the A77.

Question about the SLT and light loss is not answered clearly – the correct answer is that additional gain is applied, so in effect, the mirror does result in higher noise levels. But this has not proved to be noticeable in the A55.

Paul implies that Sony has not yet designed the next generation of full frame cameras – but later on, confirms that there definitely will be one. No-one asked about the megapixel possibilities…

No audio input level control (auto gain, 5v mic phantom power via 3.5mm stereo jack). Not much was made of this but it is the killer feature of the Canon 60D and 600D, enabling these cameras to film amplified music gigs with clean sound despite the clipping and overdrive potential of small condensors in high sound pressure. Manual volume setting is very important as music gigs are a big, big use of HD video.

Black 18-55mm kit lens will be exclusive to the NEX-7.

Firmware upgrade for NEX-3, NEX-5 and NEX-C3 will allow use of the LA-EA2.

A77 and A65 use electronic sensor based video stabilisation, not physical piezo actuation and movement of the sensor on the carriage, to reduce sensor overheating but provide IS. This may answer the question about the video HD crop, as this type of stabilisation can only be effective if the sensor is substantially larger than the image area. If this stabilisation is proposed for stills, it could result in variable crops of the image area. But no-one was asking questions at this level.

A77 MR Memory Recall – three custom setups saved, as with current Canon models. but not as convenient as the Alpha 900 with its three physical dial memory positions. Better than pure screen-menu chosen memory settings though.

Paul is now calling NEX ‘necks’ not ‘any eggs’. Good, that’s how we have always said it!

24.3 megapixel sensor creates 27.6MB raw file size, 38MB when also shooting a typical fine JPEG.

A77 movie exposure modes (P, A, S, M) can only be used if the camera is set to Manual focus; it is possible to re-autofocus during a take, but the brightness and settings appear to change.

ISO in finder, but OLED EVF can be customised to show what functions or settings you want to display, independently of what you see on the rear LCD.

September 24-25th, event at Sony HQ Weybridge, Surrey – www.sony-alpha-live.co.uk – Saturday or Sunday, team of advocate photographers, book space – £77 for first 30 users, £150 for rest. Includes free goodie, bag, lunch, transfer from rail station. Meet Paul Genge, his team, and the Alpha advocate photographers. Other companies involved will include Manfrotto, G-Tec hard drives.

(We asked later to attend this, but Press are excluded – it is strictly for paying delegates and aimed only at owners).

Question about Sigma lens compatibility – praised Sigma as an honourable Japanese company, which generally fixes the lenses as needed.

12-bit depth raw.

Over 450 users.

Did not mention GPS (we have subsequently had some complaints at PCA over the omission of GPS from the NEX-7 – ‘the ideal travel camera but no GPS is a deal-breaker’).

Sony launches new range Alpha, NEX

Posted on By

All the predicted new models from Sony were unveiled today – the Alpha 77, Alpha 65, NEX-7, NEX-5n and NEX-VG20.

Full details are up on Sony’s websites. The A77/65 cameras will be on sale from October 2011 onwards. View Sony press information online.

Those who grab the cameras will find the virtual 1.09X 100% field of view given by the OLED finders looks to be visually 10% bigger than the largest APS-C viewfinders made, an experience close to using a full frame DSLR with an optical prism (1.09X at 23mm eyepoint).

The Alpha 77 is launched with the new 16-50mm f/2.8 SSM (not SAM as rumoured!) lens, and the Alpha 65 shares the same new 2.3 megapixel OLED viewfinder technology. The burst speed of the 77 is revealed to be 12 frames per second (predictions have ranged from 10 to 15) with the A65 achieving 10. The new 19-point, 11-cross point AF module is fitted to the A77 only, the A65 has a simpler 15-point, 3-cross module.

Both have the 24.3 megapixel CMOS sensor also found in the new NEX-7 model, but only the A77 allows ISO 50 capture (all allow 16,000). The A77 has a fully articulated 3-way swivelling rear screen and the A65 a simpler 2-directional hinge. HD video is upgraded to full 50/60 frames 1080 progressive (no longer 25/30p or 1080i) with full manual control.

The A77 has a semipro spec 1/8,000th shutter speeded to 1/250th for X sync, and rated for 150,000 cycles (tests will probably showe it uses a hybrid electronic/mechanical timing method to reduce shutter wear, but you’ll have to look elsewhere to confirm that, as we are not at the launch event). It has the expected GPS onboard.

The A65 is regular plastic-skin construction (see strap lugs, above) but the A77 is moisture/dust sealed and so, according to the information, are ther 16-50mm and the new HVL-F43AM flash and VG-C77AM vertical grip. The 77 uses full size NP-FM500H batteries.

Paul Genge, Technical Field Sales Manager for Sony UK, will be online for a one-hour live video Q&A session on the company’s Facebook page from 7.30pm GMT – visit www.facebook.com/SonyUK to partticipate.

Key points: auto ISO remains 100-1600 not expanded in range on the A65, but can be user set for 100-12,800 on the A77, which also has separately set 50 and 16,000 options plus a multishot 25,600 (the A65 also has this high speed mode). The A77 offers JPEG Extra Fine, the A65 does not.

The viewfinder magnification (eyepiece/screen combination) is not stated but is superior to the A55 with a half-inch OLED.

On the A77 only, exposure bracketing has been expanded to 3 frames at 2EV and 3EV intervals, in addition to 3 or 5 frames at 1/3, 1/2, or 2/3 EV; the A65 offers only 1/3 or 2/3 for 3 frames. Peculiarly, neither offers 1 EV bracketing.

The A77 or A65 normal motordrive with full AF/AE is 8fps (slow speed 3fps), the higher speeds are obtained with Continuous Advance Priority (fixed settings during burst). Both can achieve 13 raws, 17 fine JPEGs before slowing.

It doesn’t look as if either accepts the HVL-F58AM as a wireless controller, but both have built-in wireless. The rumour of CF card compatibility in the A77 was false, the cameras have dual MemoryStick PRO Duo/SD drives.

The NEX-7

The professional NEX has the 24.3 megapixel sensor, ultra-fast response with startup and focus time improvements, the same OLED viewfinder as the A77/65 built in to the body, the same full HD 1080/50/25p movie (Europe, 60/30 US) and the same sensitivity range as the A77. Manual refocusing is possible during video, 10fps bursts can be shot, and a leather case turns the camera into a Leica-like for eye level use.

The NEX-7 has the slower 1/4,000th with 1/160th sync shutter found in the A65 so it’s not all professionally-biased. And it’s got a small buffer, allowing a mere 6 raw frames or 4 raw+JPEG in a burst, 10 JPEGs at Fine res (no Extra Fine option is offered).

All the pre-existing bells and whistles remain included, such as Sweep Pan, 3D Pan, etc.

Please note: the OLED viewfinder on all these cameras is a power hog. With the NEX, for example, the rated battery life is 350 images using the finder, 430 images using the rear screen. The bigger battery of the A77 can still only power 470 shots (because of GPS?) where the A65 manages a respectable 510. Switching to the rear screen for composition increases these figures to 530 and 560.

There is NO new updated standard lens for the NEX and the existing 18-55mm will fight it out with the increased 24 megapixels!

No GPS. No info on potential GPS attachment.

View press info online.

The NEX-5n

The 16.1 megapixel sensor, also found in the new video VG20 model, gets into the updated NEX-5 which has the same improvements in response time and focusing as the 7 (claimed doubling of readout speed from the CD-AF system).

Its USP appears to be the ability to simulate a preview of adjustments on the screen and adjust them using touch control. It has 10fps burst.

There is a new EVF attachment. View press release online.

A new battery powered LE-EA2 adaptor which allows autofocus with ALL Alpha lenses including Minolta body-drive types back to 1985 is also to be available, above. It includes a downward-facing SLT pellicle mirror (don’t know why they did not use this design in regular cameras) and a Phase Detect AF module so the NEX can behave exactly like an Alpha 55. Note the screw drive focus coupling.

Looks like a decent lens-line-up, but me, I prefer more pancakes for my breakfast, not just a stack on one…

Along with the two new NEX models, the Carl Zeiss Sonnar T* E 24mm f/1.8, the Sony E 50mm f/1.8 OSS and the telephoto zoom E 55-210mm f/4.5-6.3 OSS are to be launched. Availability of the new NEX gear should be quick – from September for the 5n, November for the 7.

The NEX-VG20

Aye well, it’s 16 megapixel video formfactor model as per VG10. See the info online. It claims the best ever video from such a camera – but they say the same about the ‘still’ models and they are probably right.

Sorry about a few of Sony’s uncropped image files with loads of white round them, they always do this and we will crop them later. But I’m due 100 miles away for a major Associateship and Fellowship annual judging to see some good photography and I have already made myself late with this! The article will be revised tonight. – David

Watch the birdie – will Sony’s GPS surprise?

Posted on By

Before reading this article, which has attracted a lot of traffic and attention, please remember this is my personal speculation and could be entirely wrong (I’ll be very disappointed if it is miles off target and they omit GPS… or my reading-between-the-lines turns out to relate to a different product like a superzoom pocket camera with improved GPS).

There are plenty of detailed rumours about the specifications of the forthcoming Alpha 77, Alpha 65, NEX-7 and NEX-5n to be found on the Sonyalpharumours website:

http://www.sonyalpharumors.com/sr5-the-full-a77-a65-nex-7-and-nex-5n-specs/

I’m not here to confirm or deny any of this (like most mainstream journalists, even those with some connection to Sony, I don’t get advance information and I am not running a camera-test website which demands a pre-production preview under strict non-disclosure terms).

The image currently circulating most, purporting to show a new Alpha – 77 or 65. Real or not, it looks good enough.

The 12fps stated maximum shooting speed of the semi-pro specification A77 fits in with information given to me as long as three years ago. A vaguely Alpha 700 like prototype was being tested in the Australasia region with 15fps. Most of the other specifications, such as the magnesium or magalloy body, were apparent right from the first mockups being shown if you know your Alpha construction. The strap lugs were the giveaway. You can tell an A900/850/700 type camera (solid metal carcase under a plastic skin) from an A1/2/3/4/5xx Alpha by the strap lugs connected through the skin to the casting.

But what Sonyalpharumours doesn’t elaborate on its something I believe Sony has put into the new Alpha 77 which will make it the ultimate cameras for bird watchers, aircraft spotters, wilderness ramblers, explorers, police forces and the military. It has GPS. I think that when it is seen by the press later this month the GPS will be a big point.

It will be the fastest locking-on GPS built in to any camera, and it will be the first to record ALL the data you need. That will include not only the latitude and longitude and height above sea level, but also the compass direction the camera is aiming in and the inclination of the camera. Combined with very accurate focal length, focus distance and AF locus data, this will make it possible to use the Alpha 77 for photogrammetry (measurement, mapping, object size identification).

I parked illegally and jumped out of the car for this shot of Bamburgh Castle from the village’s main road. For once, the Alpha 55 GPS locked on instantly and gave me the exact location of the camera on the Google Earth terrain view below.

But two days later I spent ten minutes, using a tripod, carefully photographing an uncommon slightly edible mushroom in our garden over 30 miles from this shot. Needless to say, all the frames of the mushroom display the GPS data from Bamburgh as it had failed to update its position.

This is Leucoagaricus nympharum – white field mushroom with ‘dancing maidens’ on its distinctive cap. Some sources state it is edible. For me, it was. For Shirley – noted as one to avoid for the future… but a great photographic subject. Natural light, CZ 16-80mm, 1/3rd of a second at f/14, 80mm, ISO 100, manual focus and settings.

The GPS in my Alpha 55 has been a real help in travel photography. I use Media Pro, the Phase One cataloguing and keywording software. Since this moved away from Microsoft ownership it no longer has its own own Microsoft Virtual Earth pane to open when GPS embedded data is found. Instead, it opens my web browser to the usual Google Map and Earth page. It’s not as neat as having the map tab within the Media Pro software but it works just as well.

However, the A55 GPS frequently doesn’t get a signal during many minutes of shooting at a new location. I have entire shoots of places, lasting several minutes in clear open conditions, wrongly tagged for the last spot visited. Fortunately, if I have left the camera switched on I sometimes find the correct location attached to the next place en route…

The Alpha 77 will, I believe, see an end to poor GPS and it will add the vital compass and inclination functions. Combined with the 24 megapixel resolution, near-silent mirrorfree high speed sequences, and the 1.4X and 2X teleconverter functions (cropping the sensor field but retaining full HD 1080p video, we hope) this will make the 77 the world’s best camera for wildlife safaris. And for those who like to log their natural history subjects, the accurate GPS tagging is the closest thing you can get to digital evidence of the authenticity of your shot.

All major camera companies have their eye on government and military budgets. It was the US forces’ decision to buy Topcon SLR cameras in the 1960s which gave that small but excellent camera brand a few years of glory. They achieved it by making a camera which was tougher and more versatile (in some ways) that the rival Nikon F – with accurate TTL metering that did not need a bulky prism head.

At different times Olympus, Nikon, Leica, Hasselblad and even Minolta have been favourites for government and military use. I think Sony, realising what the high resolution and very fast capture rate of their new technology mean to such users, will have sealed the deal by upgrading the GPS. The Alpha 77 will not only be the world’s best wildlife and wilnderness companion, it will also be the best evidence camera, surveillance camera and spy’s best friend.

Of course this is all pure speculation. It is based on a well-grounded hunch, and on what I would do myself, if I was in charge of the Sony development plan for the A77. There’s no way I would let another GPS module out in the world with less reliability than the average pocket digicam’s version. I would want my top SLR (SLT) GPS to be a world-beater.

Now you’ll just have to wait and see. But wouldn’t it be good if I’m right?

The truth about 24 megapixels

Posted on By

There is a rumour, which the ides of August may stab in the back or elevate to divine truth, that the coming Alpha 77 will have 24 megapixels.

Because of this rumour, there is a lot of very negative discussion going round to the effect that 24MP on APS-C is far too much and the results will be poor (etc).

Well, they may be, if you think Canon’s results are poor – you can judge that for yourself, try a Canon. But they do not have 24MP sensors!

They also do not have APS-C sensors, in the same way that Sony does. They have smaller APS-C sensors with lots of pixels cut off all round the edges. Sony has chunky big APS-C sensors with acres of extra pixels to spare. This is a slight exaggeration of the situation, but hey, I may as well join in the mood of unrestrained opinion!

Facts: Canon’s 18-megapixel sensor makes images 3456 x 5184 pixels in size (give or take a few, depending on your raw processor). Fact: their smaller 1.6X factor sensor measures 22.3 x 14.9mm. Fact: Canon states it is approximately a 19 megapixel sensor with 18 megapixel final output.

Facts: Sony’s 16.2 megapixel sensor measures 23.5 x 15.6mm and into this packs 3264 x 4912 pixels (active area).

If you made a current Canon pixel-pitch sensor the same 1.5X size as a Sony sensor, it would be around 19.7 megapixels active from a 21 megapixel total. If you put Canon pixels on an existing Sony 1.5X sensor, you would be up to 3618 x 5463 pixels and 24 megapixels needs to be 4000 x 6000.

Clearly it’s not the quantum leap some people think, just a quantum leapfrog over Canon’s back with the benefit of the larger sensor. And it’s worth considering that APS-C covers sensor sizes up to a true 24 x 16mm, for Super-35 video use, and that such sensors have already been made. A few wide-angle lenses and zooms might be a bit tight on the image circle, but that half millimetre one way, 0.4mm the other way, adds up to a surprising number of pixels, enough to take the 19.7 megapixels up to 20.7 megapixels without changing from Canon’s current pixel pitch.

So don’t panic. The chances are that 24 megapixels on proper, big Sony APS-C will perform very well. If you’ve got the glass and the technique to make it…

Wait for the NEX SLT, folks…

Posted on By

That is, the next slot in Sony’s programme of new product releases. Almost exactly five years after the Alpha 100 was launched to the world (also a Wednesday in the second week of June, back in 2006) Sony selected an auspicious date to announce the NEX-C3 and the Alpha A35. But these cameras, rather like the Alpha 100 in its day, are not what we are waiting for.

So – what’s new? 16.2 megapixels, 5.5fps native size, 7fps using a 1.4X crop (about 8 megapixels), no articulated rear screen, some candy functions in the menus for technophobes, and that accessible D-Range button can be made into a rapid custom control.

Everyone has suggested that a NEX-7 will be what they want. I rather think they will be get a NEX-C5, applying the same transforms to the 5 as the C3 (Compact 3) applies to the 3. That means it will have proper HD video, which the C3 lacks being restricted to MPEG4 HD720. Already, the rustle in the undergrowth is that the diminutive C3 misses the mark for this one single reason only. Sure, a 16.2 megapixel sensor (supposedly a new version, not just borrowed from the A55/580) is a welcome upgrade but NEX is a multipurpose system, and HD720 is back in 2006 not in 2011.

Nice mic slots, nice big CZ 16-80mm shown on the adaptor – but this, dear Sony, misses the point. We actually want the CZ 16-80mm to be updated to an SSM design so that it will focus on the NEX, and be better on the Alpha bodies, and so that its slightly manky mechanical design can be turned into something so smooth existing 16-80mm owners queue up to buy the replacement.

Good points – the shift in position of the stereo microphones to the front of the camera, the change to using a separate cover for the memory card instead of having to open the battery compartment. There’s a claim that along with a 20% better battery life, greater heat efficiency means the new cameras won’t cut out before 29 minutes is up when filming HD, even if you use SSS on the A35. Of course the NEX has no SSS but still managed to overheat, at least in the NEX-5, unless you were savvy enough to shift the rear screen away from contact with the camera back – in which case it generally keeps filming OK.

The operating times, startup, focusing speed are all reported to be much improved – by a factor of two or better. Only the image review time is worse due to the larger file size. Sony’s information makes it clear that very strong noise reduction is applied and this may affect raw files as well as JPEGs.

The new 30mm f/3.5 Macro SEL is theoretically interesting, but not so much for me personally as we have already got the 30mm f/2.8 SAM and the NEX adaptor. Eventually, you come to terms with the simple fact that a 2.5cm working distance for 1:1 shots prevents you shooting half the 1:1 shots which present themselves. You disturb the butterfly, hit bits of the plant, or cast the lens’s own shadow across the picture.

The firmware update (see end of story) to provide a ‘focus confirm’ overlay for manual focusing is actually of far more interest to the macro photographer – along with almost any other specification of macro lens except 30mm f/3.5. These lenses are fun, I love the SAM 30mm, but it’s not the answer.

The new HVL-F20S flashgun (based on the HVL-F20AM only in the design of its rotating reflector/diffuser) has changed a load since it was previewed with a mockup based on the Alpha model. Sony has decided to power it from the NEX battery, much as Minolta did with flashguns like the 316i in the early 1990s. That’s almost certainly because the NEX Smart Connector is simply not capable of holding the gun with a couple of AA cells in it, the weight would be too much.

In an ideal world, this new flashgun would do for the NEX system what its orginator does for the Alpha 900 and 850 – act as a remote wireless flash commander. But it does not, leaving NEX outside the main Alpha system still. If you want remote flash (or even just a more powerful flash mounted on a bracket beside your camera) the Nissin Di 866 MkII remains your best bet, programmable to fire correctly in synch with the NEX and to use its own auto-exposure cell for metering.

Alpha 35 – one step forward, two steps back

The Alpha 35 is similarly not earth-shattering news, especially if you own an Alpha 55 with GPS function and rather better overall performance in all respects except (perhaps) ultimate high ISO. The firmware updates for both NEX and SLT models, to be available from June 20th, add most of the benefits of the new models along with some of the child-friendly hipsta stuff. Again, wait until the next round. A higher end SLT camera is firmly promised, it’s been prototyped and mocked up and preproduced and somewhere as I write someone is actually using it.

Losing the articulated rear LCD (see above), not even replacing it with a tilting one, is a big sacrifice. The 7fps 1.4X digital tele conversion mode – with continuous AF tracking – is interesting and reminiscent of the sensor crop mode of Nikon’s first CMOS, the D2X, which was itself developed from a Sony sensor (the Cybershot DSC R-1). It shows that there are genetic traits in the Sony line that won’t be forgotten.

But is there really much point to this camera? Not much. Unlike the NEX-C3 which sees a significant body size reduction and style change, the A35 contrives to be a poor relation of either the A33 or the A55 because it lacks that excellent, reversible, twist and swivel rear screen.

Photoclubalpha has been a photographer’s thing not just a camera owner’s thing – a small difference, these days, but important. For photographers any reason to prefer the new models to what you’ve got may depend on small hidden differences which come to light as people use them. Certainly the provision of functions with changed names because no-one can be expected to understand what an aperture is, what a shutter speed is (and so on) is no reason to want the new models. Probably the reverse!

Video enthusiasts may like to note that the firmware update for the A55/33 allows all the overlaid text to be removed from the live view, which can be output from the HDMI port to surprisingly high quality. Recording devices to accept HDMI signals like this are just starting to appear at affordable prices. There’s some potential to experiment with the image provided for LV (Focus Check Live View more so than Quick AF LV) once fed into other systems free from overlays.

Version 04 firmware update for NEX-5, NEX-3
Available from June 20th, a firmware upgrade for existing NEX-5 and NEX-3 cameras adds the new ‘Picture Effect’ function as introduced on the new NEX‑C3.
