The “EF-S55-250mm F4-5.6 IS” is a telephoto zoom lens with a very small Image Stabilization (IS) unit. Image stabilization reduces blur due to camera shake by the equivalent of about four shutter-speed steps*, while maintaining excellent cost effectiveness. The inclusion of a UD (ultra-low dispersion glass) element in the design provides excellent aberration correction, and ensures excellent image quality at all focal lengths. The closest focusing distance is 1.1m at all focal lengths, and the zoom-ring pattern and coating used on our high-end models is used resulting in a firmer grip and a high-grade exterior finish.
* Generally, the accepted limit for stable unaided handheld photography is a shutter speed of about 1/[focal length x 1.6] seconds for APS-C sensor cameras.
