SONY BRINGS FULL-FRAME QUALITY TO A NEW CLASS OF DSLR PHOTO ENTHUSIASTS
SAN DIEGO, August 27, 2009 — Aimed at experienced shooters looking for value and sophisticated SLR performance, Sony today introduced the full-frame α (alpha) DSLR-A850 camera and a new 28-75mm F2.8 lens.
The α850 model shares the same 24.6 megapixel sensor and most features of the flagship α900 camera, introduced last year, but will be available for just under $2000 (body only).
"Sony is bringing the benefits of a full-frame digital SLR camera to a broader group of consumers," said Kristen Elder, director of the Digital Imaging business at Sony Electronics. "The α850 strengthens Sony's alpha DSLR line, which now offers models in each step from high-end professional down to the amateur enthusiast."
The α850 camera is designed to deliver ultra-fine picture quality with a high resolution, 24.6-megapixel, 35-mm full-frame Exmor™ CMOS sensor and fast image processing with dual BIONZ™ processing engines. It also offers high-speed continuous shooting of 24.6 megapixel images at up to three frames per second.
Ultra-Fine Images
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 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.
Image processing gets a boost in speed and power from two BIONZ 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 system applies advanced noise reduction algorithms producing images of exceptional quality and detail, especially at high ISO sensitivities.
Capture the Right Shot the First Time
The camera'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.
The camera's autofocus system features nine 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.
Ultra-Bright Viewfinder with 98 Percent Coverage
The ultra-bright viewfinder with 98 percent 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 optical surfaces to deliver its extraordinarily bright view.
A mirror box features a parallel-link mirror mechanism that moves on two horizontal axes to accommodate both the large full frame mirror and the body-integrated image stabilization system without increasing the camera's size.
Anti-Shake System for a Full-Frame Sensor
With its body-integrated SteadyShot INSIDE™ image stabilization, the camera achieves an anti-shake effect equivalent to shutter speeds faster by 2.5 to 4 stops. The anti-shake system stabilizes all Sony, Minolta and Konica-Minolta compatible lenses even wide angle or large aperture lenses.
Versatility to Unleash Creative Possibilities
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.
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 reproduction.
The a850 model features a 3-inch (diagonally), Xtra Fine LCD™ screen (921K) making 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.
The camera includes dedicated slots for high-capacity Memory Stick PRO Duo™, Memory Stick PRO-HG Duo™, HX series and CompactFlash® media.
Bright Lens
The choice of full-frame lenses to complement the α850 model is enhanced with the new SAL2875 28-75mm F2.8 SAM lens. This compact, easy-to-carry lens is ideal for photo enthusiasts looking to add a bright, general purpose zoom to their collection of full-frame optics.
Delivering excellent imaging quality at an accessible price, it offers a wide F2.8 aperture over its entire zoom range. Ideal for day-to-day shooting tasks, its bright constant aperture makes the 28-75mm F2.8 SAM particularly valuable for depth-of-field control and available-light portraits.
Pricing and Availability
The a850 (model DSLR-A850) will be available in September for about $2,000 (body only) along with related accessories. All a900 accessories are compatible with the a850 camera, including the dedicated vertical grip (model VG-C90AM). The SAL2875 lens will be available in November for about $800. All will be available at authorized dealers, at military base exchanges, Sony Style retail stores (www.sonystyle.com/retail) and at sonystyle.com.

Sony has released a full-frame 28-75mm F2.8 SAM lens to accompany its new Alpha DSLR-A850 digital SLR. The constant F2.8 lens offers a less expensive alternative to the Sony Zeiss 24-70mm F2.8 ZA for A850 and A900 owners looks for a fast standard zoom. Construction is made up of 14 elements in 16 groups, including four aspherical elements. It features the SAM (Smooth Autofocus Motor) in-lens autofocus technology, rather than the SSM system used in the ZA lens. Priced approximately at around $800 USD, it will start shipping from November 2009.
Just Posted: Our hands-on preview of the Sony DSLR A550. The recently announced (and reviewed) A380 and its A330/A230 variants were not met with universal approval. With the launch of the DSLR-A500 and A550, the bigger picture starts to become clearer, with Sony producing five sub-$1000 DSLRs tailored to a variety of needs. The Alpha 5 series is much more clearly aimed at the photography enthusiast, so we have prepared a 10-page preview detailing its specifications, features and changes. Is this the camera to put smiles back on the faces of the Alpha crowd?
Sony unveiled its second full-frame digital SLR in the shape of DSLR-A850. It offers almost all features of the company's flagship full frame DSLR A900, but at a more affordable price. It is built around the same 24.6MP CMOS sensor and incorporates A900's 3.0 inch 921k LCD, sensor-shift image-stabilization and Dual Bionz processors. The only compromise is a 98% viewfinder coverage against A900's 100% and slower continuous shooting. To complement the A850, Sony has also announced a mid-priced 28-75mm constant F2.8 SAM lens to fit with the A850's affordable full-frame ethos. The A850 will start shipping from September 2009 with the 28-75mm lens available from November 2009.
Sony has also added to its consumer-level DSLR range, with the A500 and A550 taking the count to five cameras. The DSLR-A550 and DSLR-A500 digital SLRs are based around new CMOS sensors and add a manual focus confirmation live view mode using the main imaging sensor, in addition to Sony's secondary-sensor Quick AF live view system. Both cameras feature Sony's better noise reduction, include an Auto HDR mode and offer sensitivity of up to ISO 12800. The 14.2 MP A550 features a high resolution 921k dot 3" tilt-angle LCD, while the 12.3 MP A500 comes with a 230k dot resolution 3"tilt-angle LCD.
