STEADY ON.
Digital Shake Reduction.
A creative eye and a firm hand do not always go
together. The Digital Shake Reduction feature included
in all Optios reduces camera shake and subject blur
when photographing still images. By automatically
selecting a higher sensitivity setting, the camera can
use higher shutter speeds to capture the image.
Optio cameras also include Movie Shake Reduction
for smooth video capture.
