How does a stable viewfinder image help you take better picture?
Looking into the viewfinder while focusing and framing is essential to SLR shooting, so a stable
viewfinder image
is crucial. Canon IS Lenses correct for camera shake by shifting certain optical
components in inverse relation to the lens movement, maintaining the position
of incoming light rays
on the film
or capturing elements. This means the built-in image stabilizer reduces image blur, not
only in photos but also in the viewfinder. Photographers can confidently shoot blur-free images with
reduced eye fatigue.
