Complementing the EF 17-40mm f4L USM and EF 70-200mm f4L USM, the lens completes Canon's f4L-series zoom lens range. These lenses are designed for professional photographers requiring a light zoom lens with a fixed aperture throughout the zoom range. For outstanding camera-shake reduction, Image Stabilizer allows shutter speeds of 3 stops slower than would otherwise be possible, with no perceptible increase in image blur.
The L-series is Canon's flagship professional lens range, designed to include outstanding image performance, ultimate operability, and weather resistance. The EF 24-105mm f4L IS USM offers a lightweight alternative to the renowned EF 24-70mm f2.8L USM.
Image Stabilizer
Image Stabilizer (IS) dramatically reduces image blur caused by camera shake. Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane.
The 3-stop advantage means that photographers normally shooting a 105mm lens handheld at 1/125 second can obtain a shake free result with a shutter speed as low as 1/15 second, for vastly extended ...
