EF 24-70mm f/4L IS USM
26226

Overview
The EF 24-70mm f/4L IS USM is the perfect zoom to complement full-frame DSLRs like the EOS 6D. With 2 aspheric and 2 UD elements, the EF 24-70mm f/4L IS USM delivers high- quality images with excellent detail throughout the entire zoom range. A 9-blade circular diaphragm delivers beautiful, soft backgrounds. It offers a minimum focusing distance of 1.25 ft./0.38m across the entire zoom range and has a macro mode at the telephoto end with up to 0.7x magnification (minimum focusing distance becomes 7.87 in./0.2m) and is easily accessible with a one-touch switch. It features a Hybrid IS system with up to 4 stops of stabilization, compensating for both angular and shift types of camera shake, delivering effective stabilization even in macro. Inner focusing and ring-type USM deliver, fast, quiet AF, and full-time manual focus is available for manual focusing even while in AF mode. The durable EF 24-70mm f/4L IS USM is sealed for excellent dust and water resistance plus has fluorine coating on the front and rear elements reducing smears and fingerprints. Compact and lightweight, it’s the perfect L-series lens for photographers on the go.

Perfect standard zoom
I bought this lens as standard zoom for my 7d and I compared it first with my 35mm f/1.4L and my EF 70-300mm f/4-5.6L IS USM. At 35mm the difference in terms of resolution in comparison to the fixed-focus lens at f/5.0 are very low and virtually negligible. The lens is tac sharp even wide open. At 70mm, the 70-300mm lens shows only a marginal advantage. CA is very low. At 24mm, barrel distortion is clearly visible but seems to be normal for this type of lens. This distortion can be corrected during post procession. Over all, this lens meets well the high expectations I had as standard zoom lens for an APS-C sensor camera.
