New full-frame alpha DSLR
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.
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.
