The EF 24-105mm f/4L IS II USM is a Canon L-series zoom covering wide-angle to short-telephoto focal lengths and featuring a constant f/4 maximum aperture. Version II of this popular lens sports a redeveloped optical design, which includes four aspherical elements to significantly reduce distortion and spherical aberrations throughout the zoom range for great sharpness and accurate subject rendering. Individual elements feature an Air Sphere Coating, too, to suppress flare and ghosting for greater contrast and color accuracy in harsh lighting conditions. A standard wide-angle to a telephoto zoom lens is designed for use with full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it will provide a 38.4-168mm equivalent focal length range. Four glass-molded aspherical elements, including one large-diameter double-sided glass-molded lens, help to minimize distortions and spherical aberrations throughout the zoom range in order to maintain edge-to-edge sharpness and illumination. An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four shutter speed stops to better enable working in low-light conditions and with slower shutter speeds. Rounded ten-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
