EF24-70mm f/2.8L USM

It is also good for wide-angle photography using digital SLR cameras which have a screen size smaller than 35mm. Use of two types of aspherical lens elements and a UD lens element corrects the magnification-type chromatic aberration often seen at wider angles, for extremely high picture quality. While on the one hand employing a no-compromise dust-proof and drip-proof*¹ construction, on the other hand the quiet and fast autofocus, the mechanical full-time manual focus, and the broad zoom ring make the lens easy to use, while the circular diaphragm delivers a beautiful blur effect. The closest focusing distance is 0.38m, and the magnification is 0.29x, making the lens ideal for close-up photography.
