FAQ: What kind of image stabiliser (IS) is used in my EF lens?

Helpful Information:

Solution:


All Canon IS lenses use anopticalimage stabiliser.
Camera / hand shake is detected by gyro sensors which provide data to neutralise the shake. Neutralisation is realised by a "floating" lens element that can move perpendicular to the optical axis.

All Canon EF lenses with IS in their name incorporate such an image stabiliser to prevent camera / hand shake from spoiling the shot.
This is particularly useful on close-ups, at slow shutter speeds or in situations where a tripod cannot be used.
