Sony 5″ video monitor for DSLRs
For some time, I have been using a 7″ Lilliput external monitor for my Alpha and other HDMI output cameras. This is fairly bulky, with its external battery pack, and is mounted on a flash bracket holding it to the side of the camera. The main use of the monitor is for interview-style filming with it facing the subject (self filming) but it also has uses making location shooting simpler. Such monitors are usually mounted within video rigs, off camera, often at waist or chest level even when the camera is held above and forward of them.
The cost of the Lilliput is around £150-£200 depending on supplier and battery/mains power choices. Similar monitors from Marshall and other makers typically cost two to three times this, because they are sold for the photo market – the Lilliput is sold to the in-car entertainment sector, and therefore is not marked up by 300% to allow for the deep pockets of camera owners relative to car owners.
Sony’s new 5″ monitor is much lighter, and comes with mounts for hot shoe and Alpha shoe, and a neat lightweight HDMI-miniHDMI cable (oddly enough, that’s about the hardest thing to find – a short, skinny cable). It costs $395, but for that you do get a folding hood which is neat. They have many photos of it and not one shows it facing forwards, but the use is mentioned in the publicity.
It does not draw power from the HDMI, but requires either a mains adaptor or a battery pack, which is not shown in any of the photos. Sony have done the same as LED-video-light makers – provided a bay for fitting the regular Alpha camera battery as a power source. The press release implies that the battery pack is a separate item (‘optional’) instead of making the point that you use any large Alpha battery (including old ones left over from the A100). I find it very convenient that my video light accepts the same batteries as my camera system, and not very convenient to have a bulky rechargeable pack for my 7″ monitor. (NB: all that white space is part of Sony’s image we have linked to – nothing like wasting a bit of bandwidth by not cropping pix, is there?).
Here’s the press release:

A new clip-on LCD monitor from Sony gives DSLR camera owners a bigger, better view of their footage while shooting HD video.
The CLM-V55 is a portable video monitor featuring a high-resolution WVGA (800 x 480) (5”) LCD panel. Attaching easily to most Interchangeable Lens Digital cameras and compatible HD camcorders via the supplied adaptor, it displays video footage during shooting/playback with excellent clarity and a wide viewing angle.
The clip-on screen tilts and swivels to any angle for comfortable framing in any position – even self-shooting when you’re in the picture.
The CLM-V55 is loaded with pro-style features to help photo enthusiasts and videographers shoot high-quality HD video footage with their Interchangeable Lens Digital camera.
Pixel magnification mode assists with accurate focus confirmation, giving an enlarged pixel-perfect view of a selected portion of the Full HD image. It’s complemented by a colour peaking function that highlights the edges of accurately-focused areas of the video image.
An intuitive control wheel allows quick, positive adjustment of a wide range of monitor settings without interrupting shooting. Adjustable parameters include aspect ratio (16:9/4:3), volume, brightness, contrast, colour tone (phase), colour temp and auto dimmer. On-screen markers aid precise framing by giving precise indication of a TV’s 16:9 or 4:3 actual display area. The LCD monitor’s on-board mono speaker is complemented by a headphone jack for accurate audio monitoring during shooting.
The CLM-V55 attaches easily to a wide range of Interchangeable Lens Digital cameras from Sony and other manufacturers that support HD video shooting. The supplied adaptor simplifies mounting on any camera or HD camcorder that features an auto-lock accessory shoe or ISO shoe. Signal connection from camera to monitor is via the supplied HDMI cable, while power can be supplied using a battery pack or AC adaptor (both optional). The CLM-V55 comes with a detachable LCD hood for more comfortable viewing when shooting outdoors in bright sunlight.
The CLM-V55 LCD video monitor by Sony is available from March 2011.
Alpha 55 1080p HD video – snow in Scotland
This video was made on December 23rd using the Alpha 55 (AVCHD recording) hand held, with SS enabled, and the Carl Zeiss 16-80mm zoom. This video has been uploaded in full 1080p HD and can be viewed at high resolution if you have a fast enough connection. The soundtrack is a classical guitar piece I wrote ten years ago, on the last day of the year 2000, when snow was falling by moonlight which I guess the music represents a bit better than mid-day.
Some camera-mic sound has been left in place for two of the takes, and the shot of the stone wall uses active phase detection AF during video. This was not possible for most takes, as the snowflakes falling made the focus constantly change as they passed the focus zones!
Hope you enjoy it! The camera got very wet with snow – you can see where flakes landed on the lens filter – and ended up being wiped down many times. Eventually, after going into a shop for a few minutes, everything steamed up. But it seems fine after letting it dry out and warm up. It was not very cold, around 1°C for snow to be falling like this.

The Alpha 580 – a three-way view
Once I had a quarterplate hand-and-stand camera, vintage 1920s. Attached to the front standard was a small reflex viewfinder, giving a miniature composition you could use at waist or chest level. On the same standard was a folding wire frame, with a companion eye-sighting window flipping up from the side of the body. This gave a direct view from eye level. But for the most accurate framing and focusing, a groundglass screen at back could be used with the shutter open and a viewing hood folded out.
Those three ways of viewing have never been available in a modern SLR. Until now! The Alpha 580 (for which you can also read 560 throughout this review, give or take the sensor) is the first modern SLR to offer three entirely different viewfinder systems, all with their own unique focus and exposure methods. There have been cameras made by Alpa and Praktina which had optical finders tucked in alongside their pentaprism, and Rollei invented a finder which could switch from eye-level to waist level at the flick of a lever. But the Alpha 580 offers three through-the-lens systems and it’s unlikely any DSLR will do so again.

A-mount autofocus upgrade for NEX-VG10E
Available now for download, a free firmware upgrade adds autofocus support with 14 A-mount SAM and SSM lens models. AF compatibility of the NEX-VG10E with A-mount lenses requires the optional LA-EA1 Mount Adaptor, plus a separate firmware upgrade for the LA-EA1.
Man using NEX-VG10E with 18-200mm OSS lens and mic windshield, in Fuerteventura last week. Alphaspotted by Shirley Kilpatrick.
The upgrade lets videographers enjoy smooth, accurate AF operation with the family of A-mount optics that includes telephotos, primes and zooms by Sony and Carl Zeiss.
The latest firmware upgrade by Sony for registered Handycam® NEX-VG10E customers is available free of charge from http://support.sony-europe.com/dime/camcorders/hd/msc/msc.aspx?&m=NEX-VG10E.
Editor’s comment: AF is already offered by the NEX-3 and NEX-5 with the adaptor and the same group of SAM and SSM lenses. However, it could not really be described as ‘smooth, accurate’ – more like ‘just acceptable’. So perhaps the VG10E’s firmware fix is a better one and perhaps a further firmware release may arrive improving A-mount AF with the 3 and 5.
Sony to develop Super-35mm pro camcorder
Sony Corporation announced today that it is developing a new type of E-mount interchangeable lens camcorder for professional use that is equipped with a Super-35mm equivalent large format CMOS sensor. This new addition to Sony’s professional “NXCAM” line will be available in the middle of 2011.
Editor’s Note: Super-35mm is not full frame 35mm. The 35mm movie format is what we call half-frame in still photography, or a little over 18 x 24mm – a size very close to the nominal 16 x 24mm of the DT/DX format used by Sony for APS-C sensors. Sony may decide to use a normal APS-C sensor for this, or to use a true 16:9 ratio for HD Video. However, Super-35mm normally means a squarer image format. No doubt internet forums will be full of folk claiming that Sony has gone full frame frame on the E-mount just like they said, etc etc – well, that is not the case. Super-35mm does not mean full frame (technically, double frame 35mm).
But this sensor may be significantly larger than existing APS-C, at a possible 25 x 18.5mm rather than 23.5 x 15.5mm or thereabouts (please note that one APS-C sensor is already quoted as being 16 x 24mm). Alpha A-mount lenses will of course cover this easily; E-mount NEX lenses may have been designed to do so from the start, though it may be pushing it to expect corner quality unless OS is disabled. By definition, all OS-type lenses must have a larger circle of coverage than the format they are designed for – often considerably larger. Turning off OS would enable any properly designed OS lens to cover a bigger sensor without any corner vignetting or loss of sharpness.

HD videocast – NEX adaptors and odd lenses
I’ve finally got round to trying a ‘proper’ videocast – perhaps the first of regular short demonstrations – with the Alpha 55 offering me HD filming while demonstrating the NEX-5. And I can use the NEX-5 to film stuff about the Alpha 55. A Canon 60D helped, though its inability to refocus during filming (which the NEX-5 and Alpha 55 can do) proved a small problem. The sound from the Canon was used, mainly because it had been set with a manual level, while the Sony was using an external condensor mic that pickup up some serious interference from the lights.
The lighting is nothing more than one 30W daylight colour energy saver and one 20W – using an angle desk lamp from IKEA and a spare table lamp. The background is a Calumet (Lastolite in disguise) canvas. To do the filming, I ran a 7 inch Lilliput monitor from the HDMI output of the Alpha 55, and mounted it facing me on a bar right next to the camera. The Canon was set up as a second camera and left running from that position. Editing, including cutting and pasting the soundtrack and parts of the Canon video, was in iMovie 11.
This is a full 1080p HD YouTube film – if you can view it (bandwidth is an issue) try the higher resolutions. The Alpha 55 consistently overheated at around 7 minutes, showing me a temperature warning then shutting off. The room was not warm and the camera screen was both not active, and moved away from the camera back. My first attempt at this film was spoiled by the overheating issue, perhaps because SSS was left on in error. However, on a tripod SSS is not active to any extent when shooting video (it does not have the same problems of creating blur, which happen with still images due to the way mirror or shutter vibration are reflected by the tripod). Previous time limited movies I’ve made have been hand held and of course SSS is both used and expected to be very active.

Sony Photokina Press conference video – in full
We filmed the entire Sony press conference at photokina. It is split into three sections about 7 minutes each. During filming using the NEX-5, the camera at one point started to show an overheat warning. At this point I should have moved the articulated screen away from the camera body, but did not want to interrupt a very important moment – the announcement of the A7xx. And that’s when it cut out, taking maybe 10-15 seconds for me to move the rear screen, wait a moment, and restart.
Here are the videos. They are all at 720p quality and uses the internal mic, not the add-on mic, as I was ‘travelling light’ for this conference.

NEX-5 live sound
I’ve been using the NEX-5 with accessory mic – and sometimes, by forgetting to bring it, without. Today we had the Ripon City Morris side in town, and I was taking still shots using the Nikon D3X with the new Nikkor 85mm f/1.4 AF-S G lens. The NEX was grabbed as an afterthought for video.
Well, the wind noise with the built-in mics was just too much; most of my ‘footage’ ended up on the cutting room floor. After I’d got the portraits and other shots I need for the Nikon test, I nipped back to the studio and got a 4.5m high Manfrotto lighting stand fitted with a ball head. The NEX got its accessory stereo mic (set to 90° coverage) and the 16mm lens, and despite the wind level, was hoisted aloft for the last couple of dances in the square. The 30 minutes recording time really helps. My framing was not perfect, so two of the video clips were cropped down from the original 1080p, in iMovie. It is an instant process, just select the clip, select the crop tool and trim.
Despite very definite winds blowing around the pole-mounted camera and mic, there were no wind noise issues at all. So: for outdoor shooting, the accessory mic is essential.
Here is a video made the week before, entirely using the ECM-SST1 microphone, which has no wind noise at all – see this post: ECM-SST1 microphone handheld clips.

NEX-5 with ECM-SST1 mic
Some parts of this were very close to large PA system speakers; others were close to dangerous loud instruments of war, notable Border fiddle and Scottish bagpipes from the Coldstream town pipe band (not the same as the Guards, this is the locals not their namesakes!).
Hand-held, mic set to 90 degree coverage not 120 degree. The NEX-5 only offers auto gain, not manual control of sound of any kind. 18-55mm OSS lens, stabilised but not always in stable hands. Widely varying distances from sound source to mic.
Hopefully a fair view of what the NEX-5 does in this kind of situation; and a view of why, despite the awful weather, I really don’t want to retire to somewhere warm and lose this place!
