Canon EF 24-70mm F/4L IS USM

The EF 24-70mm f/4L IS USM is a Canon L-series lens covering wide-angle to short telephoto focal lengths and featuring a constant f/4 maximum aperture.  A Super Spectra coating has also been applied to suppress lens flare and ghosting for greater contrast and color accuracy. A four-stop-effective Image Stabilizer is also used to minimize the appearance of camera shake for sharper handheld shooting. Standard zoom is designed for full-frame Canon EF-mount DSLRs, however, it can also be used with APS-C models where it provides a 38.4-112mm equivalent focal length range. Two aspherical elements minimize spherical aberrations and distortions for improved sharpness and accurate rendering. Rounded nine-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
