The Canon Zoom Lens EF24-105mm f/4L IS USM, which was designed to complete the f/4L zoom series lineup, is a standard zoom lens covering a wide range of focal lengths, from 24mm wide angle to 105mm mid-telephoto. The lens incorporates an Image Stabilizer (IS) that gives the equivalent effect of a shutter speed three stops faster, allowing the handheld capture of shots that would otherwise be blurred by camera shake.

The EF24-105mm f/4L IS USM delivers the high-contrast, high-definition images for which Canon’s L-series is renowned. Three aspherical lens elements (two replica, one glass mold) combined with Canon’s proprietary Super UD (ultra-low dispersion) lens element effectively correct chromatic aberration throughout the entire zoom range to realize outstanding image quality. Designed to meet the needs of professional and experienced amateurs for a wide range of photographic subjects, the new lens offers full-time manual focusing, which enables users to focus even in the AF mode, and a durable dust-resistant construction, ensuring unfailing performance even under harsh conditions.
