Exmor R hits the High Street – new Cyber-shots

SONY puts two 10.2 megapixel consumer digicams on the market in September 2009 using the back-illuminated Exmor R sensor. This CMOS sensor architecture takes the ‘sandwich’ which forms the light-sensitive pixel wells, and reverses it so that the side previously used for connections now faces the image-forming light. This change allows more light to be captured, resulting in improved high ISO performance. So far, the Exmor R technology has only been used in video cameras and this is the first appearance of it in still cameras. The cameras can shoot at 10 frames per second.

Alpha 500, 550 and 850

Sony’s September launch for 2009 looks set to include three new models – the Alpha 500, 550 and 850. The model numbers are confirmed by the usual backdoor leak, appearing in the registration database for SonyStyle USA in this case (Canada has been a past culprit, updating databases associated with their site before the product is officially released). However, only a few people know what these cameras will be, and they are limited by non-disclosure contracts.

'Twilight Football' concept to boost Sony low-light reputation

Sony has come up with a zany idea to overcome problems in their reputation for high ISO and low light capability – showcase cameras, including the Alpha range with its legendary high ISO noise reduction, by shooting an essentially unphotogenic subject in almost non-existent light. But they are picking exceptional locations to do so. Sony Europe is currently obsessed by football, which for two decades Canon has claimed as its own territory.

What’s in it for photographers? Less than there is for amateur footie players, as it seems unlikely the public will be able to join the ‘specially selected’ teams of still and movie shooters.

Sigma’s DP2 – Camera less obscure

sigmadp2_page_02_image_0001

Sigma’s DP1 was launched in 2007 (with production models available in 2008) to great critical acclaim. occupying a unique spot in the marketplace by combining an APS-C format sensor with a compact “point and shoot” style body. There were a few controversial design choices, and the user and reviewer feedback varied greatly with the time and effort people were prepared to put in learning about the camera, yet the verdicts on the optical performance were united – the DP1 was astounding. Now the DP2 has arrived, with production-quality units available from UK retailers.

Sony CMOS sensor background revealed

There is a white paper by Sony Semiconductor on the imaging processing which I think is in the HX1, http://www.sony.net/Products/SC-HP/cx_news/vol55/pdf/featuring55.pdf. I assume it is the IMX-032 CMOS sensor (http://www.sony.net/Products/SC-HP/cx_news/vol55/np_imx032cqr.html) mated to a CXD4109AGG image processing chip. There seem to be some interesting techniques employed, multi-plane synthesis to combine several frames for low light and HDR capture.
With the IMX-032, it is interesting to note that the on-board programmable gain amplifier has a gain value of up to 18dB or a factor of 8, so if base ISO is 80, then maximum “analogue” ISO is 640. If we compare the IMX-032 versus Sony’s first column ADC CMOS chip (IMX-017), the IMX-32 has an 11.8% better photo-electron efficiency per unit area (2300e per 1.75 micron square pixel compared to 4500e per 2.5 micron square pixel). Might be a sign that Sony is improving the process and design used to make their CMOS chips.
The backside illuminated chip is called the IMX-061, http://www.chipworks.com/uploadedFiles/Aliased_Pages/CMOS_ImageSensors_Spotlight/Chipworks%20-%20Sony%20IMX061%20EXR-0902-813.pdf
6MP and 1.75 micron pixels in ClearVID (45 degree) layout with a 1:6:1 RGB Bayer filter array, sacrificing colour resolution for spatial resolution.
The Nikon D90 chip is called the IMX-038 (not the IMX-021 as for the A700), so this suggests it has significant revisions compared to the IMX-021 (possibly linked to LiveView and HD Video?).

Sekonic's camera calibration

The Sekonic Digitalmaster L-758D meter offers the solution to variable ISO/EI ratings, and apparent sensitivity and contrast curves variations found in DSLRs. With a USB interface to link it up to a PC/Mac calibration program, the L-758D can remember three different cameras, two types of lighting (ambient or flash) and two measuring methods (incident or reflected) plus a range of ISO values for each of the cameras. There are twelve basic ‘profiles’ that can be stored, and within each profile a range from ISO 3 to ISO 8000.

Exmor 'R' debuts in Handycams

Sony’s new back-illuminated CMOS sensor design makes its first appearance – along with technology borrowed from the Alpha system – in a new HD Handycam video model, the HDR-XR520VE/500VE. Hopefully presaging future DSLR developments, the range also includes models with built-in GPS tracking to record the location of shots as you film.

Sony Alpha 900 and Nikon D3X raw file noise comparison

Like Mike Johnston writing in The On-Line Photographer, I’m aware that any attempt to line up one or more cameras and show comparison images or make judgements is on to a loser from the start. And any webmaster who puts an external link in the first half dozen words of a new post is losing the plot too! But here, for what it’s worth, is the first line-up of results processed using the same software from A900 and D3X uncompressed raw files converted without sharpening or noise reduction.

Nikon D3X announced at last!

RRP: £5499.99 / €7728.00
Availability: Late December 2008

Nikon UK is pleased to introduce its new top-of-the-range premium D-SLR – the D3X. Building on the reliability, handling and durability of the award-winning D3, the D3X offers an imaging sensor with over twice the resolution* of the revolutionary D3, breaking new ground in image quality.

(*Nikon’s own words – actually, it’s twice the pixel count, and approximately 1.42 times the linear resolution, as resolution is normally understood, though the visual information density is more than doubled).

The all-new 24.5MP CMOS* sensor makes the new model eminently suitable for the broadest range of shooting situations, both in the studio and on location – ideal for photographers seeking unrivalled detail.

(*Nikon’s own words again – we must wait to find out whether it is really all-new, or is a derivative of the Sony 24.x megapixel sensor. See features below of gapless microlens array and 12-channel readout, which are not claimed by Sony. Samsung pioneered gapless microlenses in the 14.6 megapixel sensor for the Pentax K20D/Samsung GX20).

“This is the camera that many professional photographers have been waiting for,” said Robert Cristina, Professional Products and NPS Manager at Nikon Europe. “Just as the D3 has become the professionals’ camera of choice in sports photography, the D3X’s extremely high imaging resolution will raise the bar for commercial, fashion and stock photography. The results speak for themselves: this is without doubt our highest-quality camera to date.”

The World is Your Studio

The D3X boasts a specially-developed FX-format CMOS image sensor with 12-channel readout, gapless micro lens array and on-chip noise reduction. It delivers class-leading levels of continuous shooting speed and noise management at higher sensitivities without sacrificing detail.

The D3X supports a broad ISO range from ISO 100-1600, extendable down to ISO 50 and up to 6400 equivalent with up to 5 fps continuous shooting at full resolution, or 7 fps in the 10MP DX-crop mode. The acclaimed MultiCAM3500FX 51-point autofocus system enables extreme accuracy with outstanding dynamic tracking for fast moving subjects in low light.

The camera’s LiveView function offers a smooth workflow option, perfect for studio work or other situations where the use of the viewfinder is impractical. The camera also delivers a superb response rate, with a start-up of just 12 milliseconds and 40ms shutter lag. The Kevlar/carbon fibre composite shutter has been designed for intensive professional needs and tested to 300,000 cycles.

Images with the X factor

The D3X reaps the benefits of the very latest developments in sensor design and image processing technology. Designed to produce files suitable to meet the demands of tomorrow’s commercial and stock requirements, the camera produces 50MB 14-bit NEF (Raw) files. Using Capture NX2 software, NEF files can be processed into medium format terrain; 140MB (16-bit TIFF-RGB). Fine details are reproduced with incredible clarity, whilst shadows and highlights contain tonal gradation with minimal clipping for pictures with a unique look and feel.

Intuitive control

The D3X shares the same ergonomics and handling as the D3, which have been designed to enable anyone to get to work quickly and efficiently. The bright, uncluttered viewfinder features 100% coverage and comprehensive illuminated displays, while the high-definition, 3-inch, 920,000-dot VGA TFT monitor enables outstanding playback quality for on-the-spot image assessment. The D3X’s magnesium body, which is sealed for moisture and dust resistance, also supports Nikon’s wireless system (the WT-4), HDMI output, offers a dual slot for CF cards and is compatible with the new GP-1 GPS unit.
