| Packed with innovative features to get the best shot, the rugged Sony A850 DSLR camera features a 35mm full frame 24.6 megapixel Exmor CMOS image sensor that provides a larger capture area, improved wide angle performance, and tighter depth of field control. The A850 also incorporates SteadyShot INSIDE in-camera image stabilizer which actually shifts the image sensor to compensate for camera shake without sacrificing image quality. Additional features include Dual BIONZ imaging processors for continuous shooting at up to 3 fps, an ultra-bright glass pentaprism viewfinder, 3.0-inch Xtra Fine LCD display and HDMI output. 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. 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. Optional New All Bright Lens
The choice of full-frame lenses to complement the a850 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. Expanded Creativity

Brilliantly capture your subject and expand your creativity with an unlimited range of accessories. From lenses and flashes to filters and grips, the A850 offers solutions to satisfy even the most demanding photographer. Extraordinary Durability
The finest build quality to match the finest in imaging. The a A850 is constructed of a rugged and lightweight magnesium-alloy body for durability, while the moisture and dust-resistant design make this DSLR camera safe to use in a variety of environments. 35mm full frame 24.6MP Exmor CMOS image sensor
The A850 features a 35mm full frame Exmor CMOS image sensor that is approximately 2.35x larger than the APS-C sized sensors found in many DSLR cameras. The result is a larger capture area, improved wide angle performance, and tighter depth of field control. In addition, its 24.6MP resolution maximizes the resolving power of your existing lenses and delivers sharper, higher contrast photos. SteadyShot INSIDE in-camera image stabilization
Building on years of expertise, Sony has developed the world's first body-integrated image stabilization solution for a full frame DSLR1. The SteadyShot INSIDE in-camera image stabilizer actually shifts the image sensor to compensate for camera shake without sacrificing image quality. The compensation effect is equal to as many as four shutter speed steps, giving you more creative freedom when shooting in low light. And, because it is integrated into the camera body, SteadyShot INSIDE technology works with all compatible a system lenses. Dual BIONZ processors for up to fast 3fps performance
