SONY UNVEILS FIRST FULL-FRAME ALPHA DSLR MODEL

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 ThemThe 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 SensorThe 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 ResponsivenessThe 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 PossibilitiesThe 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 HandsIts 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 AccessoriesThe 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.

Sony Press Release


Tokyo, Japan – Sony Corporation today announced the development of a 35mm full size (diagonal:43.3mm/Type 2.7) 24.81 effective megapixel, ultra-high speed high image quality CMOS image sensor designed to meet the increasing requirement for rapid image capture and advanced picture quality within digital SLR cameras.

Development background

In recent years, the demand for digital SLR cameras featuring high resolution and wide graduation ranges capable of capturing every detail of the subject matter has continued to increase, particularly among high-end amateur users. Additionally, the increasing user requirement to shoot from the same focal length and angle as 35mm film cameras using interchangeable lenses has led to significant interest in the development of 35mm, full size CMOS image sensors.
However, there are a number of technical challenges to developing full (large) size image sensors, such as the propagation delay caused by using extended power circuitry and signal lines, and the difficulty of maintaining uniform sensitivity and signal saturation across the surface of the screen.
Furthermore, because current semiconductor exposure systems are unable to cover the entire chip surface of 35mm full size CMOS image sensors, multiple exposures are required. This results in the difficulty of accurately controlling exposure variance and matching circuit patterns.

Advantages of this device

The newly developed CMOS image sensor combines unique circuit design technology with Sony's advanced fabrication expertise, including a system of joining multiple exposed patterns together and advanced planarization for minimizing fluctuation, to realize 35mm, full size, 24.81 effective megapixel resolution. Sony’s“Column-Parallel A/D Conversion Technique - also provides each column within the sensor with its own A/D converter, minimizing image degradation caused by the noise that arises during analog processing while at the same time delivering an extremely high signal conversion speed.
The enhanced image quality generated by the sensor’s 24.81 effective megapixel resolution, wide range of graduation expression achieved by its full size broad dynamic range, and the low noise, high resolution, ultra-responsive performance provided by Sony’s Column-Parallel A/D Conversion technique enable it to meet the ever-increasing requirements within high performance digital SLR cameras.
Sony will target for mass production of this CMOS image sensor within this year.
