Features

Overview: The Canon EF 24-70mm f/2.8L II USM lens is a standard zoom lens for Canon EOS full-frame and APS-C cameras. On cameras with an APS-C image sensor, the lens provides a 38.4-112mm equivalent focal length range. The inner focus system and ring-type USM (ultrasonic motor) gives you faster, more precise auto focusing. The lens mount has a rubber ring for enhanced dust and water resistance. The 9-blade circular aperture diaphragm provides beautiful soft backgrounds, while the fluorine coating on the front and rear lens elements reduces smears and fingerprints.

Focusing Ring: Regardless of whether you're in manual or auto focus mode, the full-time focusing ring always works. This means you can auto focus on a subject (One-shot AF), but manually change the focus by turning the focusing ring.

Focus Mode Switch: You can switch between Auto Focus and Manual Focus using the two-way AF/MF switch on the barrel of the lens.

Zoom Ring Lock: To keep the lens from inadvertently extending, you can lock the zoom ring to keep the lens at the shortest point.

Lens Hood: The EF 24-70mm lens comes with the EW-88C lens hood, which cuts out unwanted light and protects the front of the lens from rain, snow, and dust. The hood can be inverted and mounted backward on the lens for storage while not in use.
