Sony DSLR-A850 Specification Guide
DSLR-A850
Digital Single Lens Reflex Camera
The rugged Sony® α850 DSLR features a 35mm full frame 24.6 megapixel Exmor™
CMOS image sensor and SteadyShot INSIDE™ body-integrated image stabilization
for a full frame DSLR. In addition, Dual BIONZ™ imaging processors allow
continuous shooting up to 3 fps with superb image quality and ultra-low noise.

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
