Mount Converters for Different Image Format Size Cameras
Canon offers a variety of Mount Converters to be used between a lens and a camera of different image format sizes. Each converter will extend the effective angular field of view of the associated lens according to the Shift Ratio listed below

Optical Shift Image Stabilizer (Shift-IS) Technology
The history of field lenses is a history of zoom ratio/focal length extension. It came to a point where the industry thought it would be impossible to push the envelope any further. The telephoto focal length of the lens became so long that even the slightest amount of wind or operator movement would cause image shake and viewing the picture became intolerable. This was before Canon announced the incredible magnification of the DIGISUPER 86xs zoom lens. Canon, renowned for its optical image stabilization technologies, developed another new stabilization solution for the broadcast field lens, a

How the Optical Image Stabilizer (Shift-IS) Works.
When the lens moves, the light rays from the subject are bent relative to the optical axis, resulting in an unsteady image because the light rays are deflected. By shifting the IS lens group on a plane perpendicular to the optical axis to counter the degree of image shake, the light rays reaching the image plane can be steadied. Since image shake occurs in both horizontal and vertical directions, two
