Alpha 850

Precise and fast 9-point AF system w/ 10 point assist
A high-performance autofocus system uses 9 focus points (center dual-cross type) and 10 assist points to deliver fast and precise focusing.

Rugged magnesium alloy shell
The body of the Sony Alpha 850 is entirely covered in a die-cast magnesium-alloy shell, providing a rugged feel and surprisingly lightweight.

Moisture/dust-resistant design

Sealed viewfinder optics and rubber gasket surrounds on all buttons, dials, and switches help resist the entry of dust and moisture into the

camera, and allow for safe use in a wide range of environments.

Anti-Dust Technology Changing lenses in a DSLR can allow dust to enter the camera — so to help keep the CMOS imager cleaner for better pictures, the Sony a; (alpha) Alpha 850 utilizes both static-free anti-dust coating on the imager’s filter and anti-dust vibration that automatically shakes the sensor to dislodge dust each time the camera is shut off.

Battery Performance
A supplied InfoLITHIUM lithium-ion battery provides long-lasting performance, allowing you to capture approximately 880 images on a single charge.

Durable Shutter Design
The shutter mechanism in the Alpha 850 is designed to achieve shutter speeds up to 1/8000 seconds and proven for 98,000 cycle operation.

Dual Card Slots
The Sony Alpha 850 features a dual card slots and accepts both CompactFlash and Memory Stick Duo Media (sold separately).

40-Segment Multi-Pattern Metering
A 40-segment multi-pattern metering system provides superior exposure control accuracy in a wide range of lighting conditions.

Dynamic Range Optimizer
To recover details in dark or bright areas of the image, the Alpha 850 provides multiple levels of Dynamic Range Optimization: Standard mode, to improve shadow detail using standard gamma curves; Advanced Auto mode, allowing you to select any of 5 DRO correction levels, or DRO Advanced Bracketing, which automatically takes three shots at different DRO levels with a single shutter press.

On-Chip Column A/D Conversion
Analog-to-digital signal conversion is performed by the full frame Exmor CMOS image sensor.

Dual Noise Reduction Processing In addition to digitizing analog signals, the full frame Exmor CMOS image sensor also performs both analog and digital noise reduction. This on-chip dual noise reduction process aids in the high speed transfer of noiseless digital signals.
