CMOS image sensor
CMOS image sensor
The A900 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

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
