Sonys pressmeddelande
SAN DIEGO, Sept. 9, 2008 — Sony is introducing its full-frame α (alpha) DSLR-A900 camera, aimed at serious photo enthusiasts looking for traditional SLR performance with the added benefits of digital photography.
It is designed to deliver ultra-fine picture quality with the world’s highest resolution, 24.6-megapixel, 35 mm full-frame CMOS sensor and fast image processing with a new dual BIONZ® processing engines. The camera is also the first to have a body-integrated image stabilization system for a full-frame sensor with Sony’s SteadyShot® Inside anti-shake system.
One look at the camera’s distinctive pentaprism and nostalgic body design will evoke its full-frame optical performance. It features a bright, clear optical viewfinder with 100% field of view coverage that would impress even film photography loyalists.
“The α (alpha) DSLR-A900 introduction solidifies Sony’s position as a leading camera manufacturer that can meet the demands of serious enthusiasts,” said Phil Lubell, director of digital camera marketing at Sony Electronics. “It represents the best in sensor and image processing technologies and offers enhanced functions, performance and reliability so photographers can push their creativity to the limit.”
Ultra-Fine Images As The Human Eye Perceives Them
The camera’s Exmor™ CMOS sensor delivers the photographic expressive power of wide angles and perspective that only a 35 mm full-frame sensor can offer, and is designed to take advantage of the resolving power of high-precision α (alpha) lenses. Its high pixel count and large size provide enhanced image detail and a wider dynamic range for natural color reproduction and subtle tonal gradations.
The sensor is produced using proprietary Sony planarization technologies to ensure an ultra-flat surface across the entire imaging area. Instead of a single analog/digital convertor, the sensor uses over 6,000 on-chip, column-parallel A/D converters to convert analog signals to noise-resistant digital signals at the earliest possible stage. The result is reduced noise and high-speed transfer of data.
Image processing gets a boost in speed and power from the application of two BIONZ image processing engines. Large amounts of data captured by the 24.6-megapixel sensor can be quickly processed to achieve a fast shooting response. Additionally, this dual BIONZ processing system applies advanced noise reduction algorithms producing images of exceptional quality and detail, especially at high ISO sensitivities.
World’s First Anti-Shake System for a Full-Frame Sensor
The camera’s newly-developed, body-integrated SteadyShot Inside unit achieves an anti-shake effect equivalent to shutter speeds faster by 2.5 to 4 stops. This new unit provides stabilization for Sony, Minolta and Konica-Minolta wide angle, large-aperture lenses, which is difficult for lens-integrated systems.
State-of-the Art Optical Performance and Responsiveness
The ultra-bright viewfinder with 100% field of view coverage and 0.74x magnification enables accurate framing and preview. It features a high-power condenser lens, an eyepiece with high reflective-index glass, and a multi-layer, anti-reflective coating on every optical surface to deliver its extraordinarily bright and accurate view.
Additionally, the focusing screen is user-replaceable, with additional L-type (grid pattern) and M-type (super spherical acute matte) screens sold separately.
The camera’s newly-developed autofocus system consists of nine wide-area sensors with 10 assist points for improved tracking of moving subjects. A center dual cross sensor comprised of two horizontal and two vertical line sensors as well as a dedicated f/2.8 sensor are included to achieve greater precision, especially when using fast-aperture lenses.
It also offers high-speed continuous shooting of 24.6 megapixel images at five frames per second. A newly-designed mirror box features a unique parallel-link mirror mechanism that moves on two horizontal axes to accommodate both 100% viewfinder coverage and the body-integrated image stabilization system without increasing the camera’s size. The mirror box also has a new moving magnet actuator, a high-powered coreless motor for a faster shutter charge, and a magnet catcher to minimize mirror bounce and light refraction within the box.
Versatility to Unleash Creative Possibilities
The model’s innovative intelligent preview function takes the guesswork out of setting up a shot and the hassle of taking multiple shots to achieve a desired effect.
After pressing the depth of field preview button, the camera “grabs” a RAW preview image which is processed and displayed on the LCD screen. You can then fine tune white balance, determine the best level and effect of dynamic range optimization, adjust exposure compensation and check histogram data, all before you actually take the picture. Preview images are not recorded on the camera’s memory card, thus saving capacity.
Other key features aimed to expand creative options include the Dynamic Range Optimizer (DRO) with five levels of user-selectable correction as well as DRO bracketing for enhanced scene analysis and graduation optimization. EV bracketing with ±2EV range makes it easy to create high dynamic range composite images.
Thirteen creative styles can be selected to enhance images and then fine-tuned by customizing contrast, sharpness, zone matching and other parameters, while 3 user-programmable memories provide instant access to as many as 26 different mode settings.
Powerful RAW file processing control is put in the photographer’s hands with the included Image Data Converter SR3 software that delivers faster file processing speeds, easy adjustment of image parameters, Dynamic Range Optimization and a new Peripheral Illumination function that compensates for corner light fall off.
With the camera’s HDMI output and Photo TV HD mode, your creative output can be enjoyed on a compatible HD television. This mode brings the look of actual printed photography to the television, by fine-tuning such image parameters as sharpness, gradation and color.
Comfort in Your Hands
Its construction features rugged, lightweight magnesium alloy with moisture-resistant, rubber seals for buttons and dials, an anti-static coating to prevent dust adherence to the imager, and a high-endurance shutter rated for more than 100,000 release cycles.
It has a 3-inch, Xtra Fine LCD screen (921K) makes it possible to check focus and image quality with accuracy. It incorporates an easy-to-see display with a quick navigation menu to easily access common functions without interrupting your creative flow. A backlit LCD panel sits on top of the camera and displays key settings.
System Expansion with New Accessories
The A900 camera will be accompanied with an array of accessories like the recently-announced Sony HVL-F58AM flash unit with its innovative Quick Shift Bounce system, powerful performance with a guide number of 58, and wireless auto flash ratio control.
The Sony® VG-C90AM vertical grip offers the same ease of operation when shooting vertically as horizontally, with its button layout and low-position shutter-release button. It also houses two InfoLITHIUM® batteries (sold separately) for longer shooting and playback.
The DSLR-A900 body will be available in November for about $3,000 along with related accessories. All will be available at authorized dealers, at military base exchanges, Sony Style retail stores (www.sonystyle.com/retail) and at sonystyle.com. Online pre-orders begin online on Sept. 10.

Men visst låter det bra!!
Fullformatsensor bla.
Men snart kommer nästa modell från en annan tillverkare ,
å då e den här gammal,
och allt blir billigare....
Inte lätt inte! ;)

inte minst för att beg-priserna på A700 ÄNTLIGEN kommer rasa. Priset är fortfarande PÅ TOK FÖR DYRT för A700. Och ja, även för denna. Men den lär hamna runt 22 000- 23 000 utrikes ändå. Bra jobbat, Sony. Jag ska inta ha er kamera, men den är bra för konkurrensen.
1) lägre priser på DSLR i småbildsformatet från andra tillverkare,
2) ökad betoning på DSLR i småbildsformatet,
3) allt fler och spännande finesser i kommande DSLR,
4) fler och bättre objektiv för småbildsformatet.
Detta är nog en start på "billiga" FF kameror :)
Äntligen, hoppas att detta ger tamron och sigma en spark i baken till att släpper sina objektiv som tidigare bara finns till Nikon o Canon. Tex.
120-300mm 2,8
70-200mm 2,8.
80-400mm 4,5-5,6
50-150mm 2,8.
4,5mm 2,8.
10mm 2,8
50mm 1,4
30mm 1,4
Kollade även Sonys övriga modeller. A700 (12.2mp 5 b/s m.m) för ca: 12000 kr samt A350 (14.2mp 2.7 vikbar skärm m.m.) för 6500:- verkar vara mkt bra kameror de också. Bildstabilisering direkt i husen öppnar för en hel del intressanta objektiv som nämndes tidigare, tex Tamrons 200-500mm vore då inte fel.
Får hålla tillgodo ett par år till med min föråldrade D300 innan jag har råd att byta upp mig till ett modernt fartvidunder som a900 :D
Beror väl på hur man ser det, denskall ju precis som Nikon mycket väl kunna ta "crop" objektiv och då bara utnytja en storlek av sensorn motsvarande aps-c fromat.
Och med tanke på MP talet borde där ju vara nog av pixlar kvar även för dom.
Det jag är mest nyfiken på själv är om dom lyckats lösa den trådlösa blixten på något sätt utan inbyggd, eller om man måste ha en kontroller eller en 58hvl.
Mvh.
Att Nikon köper sin full formats sensorer från Sony beror sannolikt på att den är billigast. Eftersom Sony är kända för att göra bra komponenter, är detta också ett vägande skäl.
Jag är själv en Nikon fantast och har varit genom alla år, men jag förstår att det sker omstruktureringar bland kamera tillverkarna, såväl som bland andra tillverkare.
Sony är ett jätte företag i elektronik världen, och deras ambition är självfallet att bli störst.

Användar intryck från fotografen Doug brown efter en fotosession i Toronto.
När Nikons D3:a och 300:a kom stod det att 300:ans DX sensor var en Sonysensor men att D3:ans FF var Nikons egen konstruktion.
Stämmer inte det?

Döm själva ...
Håller med Per Folkesson, jag skulle nog gjort samma sak!
"First, the firmware is not final release and they expect to improve high ISO. At the moment it is slightly better than the A700 due to 5.9µm pixels instead of 5.5µm pixels. The crop mode can definitely be turned off for DT lenses (it is automatic, but that can be disabled) and no-one asked whether you can invoke it for FF lenses - but no faster frame rate is possible, it is still 5fps. The raw file however is cropped, so faster to transfer/process. Also, the sync speed is not 1/300th (this was doubly assured to me by an early user in Australia) but 1/200th with SS, 1/250th without - much as I suspected (I felt it might even be slower, but they have managed to keep both this and the SSS-SS performance on a part with the A700).
The 70-400mm is awesome, I used a DO NOT USE prototype! Same for the 16-35mm, also marked DO NOT USE. The viewfinder is truly exceptional, it is 40% brighter than the A700 well as larger, and 20% brighter than any other current DSLR finder, and has zero distortion and coma aberration in the eyepiece so you really see an amazingly sharp, clear corner to corner image ‘like.no.other’. With fast lenses, it really does look brighter than the view seen by the naked eye - a psychological effect maybe, but this finder makes you want to shoot everything in sight. It makes ordinary subjects look like works of art.
There are 30 lens registers for FF/BF correction and +/- 20 steps (20 either way) enterable. CF card and MS card can not do sequence or dual writing. The Intelligent Preview can not be saved, it is a mini-raw file of some kind to which wide adjustments can be carried out and seen on the screen - WB, override, exposure changes, contrast, colour, etc - and then when you press OK these parameters are saved for your shot, which you must then take.
It has true mirror lock-up and all the creative styles can be applied in either AdobeRGB or sRGB - they are not just limited to sRGB as before.
I made a sound recording of the entire conference and Shirley intends to transcribe it, either with a summary and quotes, or verbatim. Duncan’s images - he actually only had the camera for 10 days! - were just awesome. Finally, they used a real photographer and not some crummy celeb or Magnum C-lister, and they got pix which absolutely showed off the camera as a major tool for landscape, architectural and action work. The AF is much improved and the SSM on the new lenses just zips in - very fast compared to the classic 70-200mm gentle action.
My Mac Powerbook battery went and died (total collapse) so I did not post anything after the conference, and we had a great dinner with the Red Hot Chilli Pipers (rock pipe band) as cabaret. I am not joining the field shooting trips tomorrow but senior European staff at Sony are trying to arrange for me to pick up a camera body at the end of the day when they have finished, to have for a few days to try more varied subjects than the street outside a hotel window.
I’ll update in the morning. I have an entire 4GB new Sony fast MS Duo Pro HG card filled with pix and of course, it’s not proving easy to read - I may even need to buy a new card reader to handle it. I am having to use my A700 as a card reader - the first time I plugged a camera into a computer for a few years, I’ve always had card readers instead.
And I don’t have the updated software needed to convert the raw files.

Jag är tämligen säker på att priserna på kamerahus är så pressade de kan bli, eller har du bättre information? Vissa produkter går med mer plus för att kunna finansiera andra som går med minus och även R&D. Ska allt vara maximalt prispressat under produktens hela livscykel så kommer utvecklingen att gå saktare.
Det borde innebära en press på Nikon & Canon framför allt på deras bildstabiliserade objektiv.
Har man tur så blir det en stor prisminskning på nya bildstabiliserade objektiv och framförallt begagnatpriset på dessa borde gå ner när folk byter bort C & N.
