A versatile one-lens solution for many shooting situations, the EF 24-105mm f/4L IS USM Lens is a Canon
L-series zoom spanning a useful wide-angle to short-telephoto range and
featuring a constant f/4 maximum aperture. Complementing the flexible
design is an advanced optical layout that includes one Super UD element,
which reduces color fringing and chromatic aberrations in order to
realize a high degree of color accuracy and clarity. Three aspherical
elements are also featured, and minimize distortion and spherical
aberrations for improved sharpness. Additionally, a Super Spectra
coating has been applied to individual elements to control flare and
ghosting for high contrast and neutral color fidelity.
Balancing the refined optics, this 24-105mm f/4 also sports a ring-type
USM and internal focusing mechanism to enable quick, quiet, and accurate
autofocus performance, as well as full-time manual focus override. A
four-stop-effective Image Stabilizer is also used to minimize the
appearance of camera shake for sharper handheld shooting. Additionally,
this lens is weather-sealed and has a protective fluorine coating on the
exposed elements for use in trying environmental conditions.
