Canon, 24-105mm f/4L IS USM Zoom Lens (EF)

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.
