The high-resolution CMOS sensor assures detail-packed pictures with excellent contrast and gorgeous colours. Exmor technology cuts noise while signals are converted to digital form. The result? Flawlessly beautiful images.
Don’t miss those vital details. The Xtra Fine LCD screen gives you an incredible view of all your shots, with superb colour reproduction and contrast. It’s ideal for checking correct focus and exposure when you’re reviewing pictures after shooting.

Magnesium Alloy
Take a look through the bright optical viewfinder. You’ll be amazed by an exceptionally clear view of your subject, with 98% field coverage… so what you see is exactly what you shoot. Connect the camera to your BRAVIA television - then effortlessly control playback functions with your BRAVIA TV’s remote. There’s no need to get up from your favourite chair to enjoy the show in sparkling HD.
It’s all about inner strength. The rugged aluminium chassis is teamed with magnesium alloy body panels for extra strength while keeping weight to a minimum. Vulnerable controls and other sensitive areas are protected from dust and moisture for worry-free outdoor shooting. Ruggedly built for unflinching pro-style handling and performance, the A850 shares the same 24.6 megapixel sensor and virtually all features of the flagship DSLR-A900, introduced last year. Like its full-frame sibling, the A850 fully exploits the creative possibilities of the α family of lenses that includes premium full-frame optics from Carl Zeiss, plus five high-performance G Lens models.

BIONZ Processor & High ISO
The purity of high-resolution image data captured by the full-frame sensor is optimised by two-stage noise reduction in both analogue and digital domains. Noise reduction is first applied as the full-frame sensor converts light to electronic signals. Dual BIONZ™ image engines process large amounts of digital data, applying finely-tuned noise reduction during image processing to deliver pictures with extremely high level of sharpness and minimal noise level. This combination of high native sensor resolution and powerful noise control techniques ensures superlative image quality, even at high sensitivity settings up to a maximum ISO 6400 (with expanded ISO range). The camera’s optical glass pentaprism viewfinder aids accurate shot composition, offering an extremely bright view with minimal distortion and a generous 98% field coverage.
Serious enthusiasts will also prize the camera’s fast, high-accuracy autofocus system that provides excellent framing freedom while making it easier to achieve optimum focus with moving subjects. The 9-point AF system is supplemented by 10 focus assist points to assist subject detection, improved out-of-focus detection to reduce focus hunting and a dedicated F2.8 sensor for enhanced AF accuracy with wide aperture lenses.
