Description from CameraPro:
The newly developed and released EF 24-70mm f/4L IS USM lens is a light and compact standard zoom lens with high image quality and a full-fledged macro shooting mode. The EF 24-70mm f/4L IS USM is the perfect companion to Canon’s new EOS 6D which is a compact, lightweight full–frame camera.
** Equipped with 2 aspherical lens elements and 2 UD lens elements which allow the lens to achieve high resolution throughout the zoom range and image area. Lens coating optimization achieves both a reduction in ghosting and optimal colour balance.
** Setting the zoom ring to macro at the telephoto end allows for macro shooting. Image Stabiliser delivers a level of sharpness equivalent to a shutter speed setting up to four stops faster. Equipped with a hybrid IS function which provides effect image stabilisation during macro shooting.
** Dust-proof, drip-proof construction around the mount, switch panel, zoom ring, focusing ring and zoom ring lock lever allow the lens to be used in more harsh environments.
** Compact and lightweight design along with top quality leather-texture coating and equipped with a zoom ring lock which prevents the lens extending when being carried.
