The Canon EF-S55-250mm f/4-5.6 IS II is a lightweight, compact telephoto zoom lens specifically for cameras that take EF-S lenses.
It is a worthy successor to the EF-S55-250mm f/4-5.6 IS and features a revamped external design.
The lens also continues features such as the optical system of the EF-S55-250mm f/4-5.6 IS, established for its UD lens, which ensures superb image quality by providing correction for chromatic aberration, and the roughly four-setting* faster image stabilizing effect.
* Based on a shutter speed of “1/(focal length x 1.6)” seconds, considered the limit to prevent camera shake during hand-held photography
