The EOS-1D Mark III is fully compatible with Canon’s world-renowned professional EF lenses (except the EF-S series). The lineup now includes over 50 models, ranging from 14mm ultra-wide-angle to 600mm super-telephoto, meeting various professional needs smoothly and smartly. When mounted, Canon’s intelligent EF lenses communicate f-number, focal length, and other data to the camera for fast, precise operation. With sophisticated optical know-how and micron precision engineering, Canon offers such advances as microcomputer controlled image stabilization, silent operation via ultrasonic motor plus lenses like fluorite, Ultra Low Dispersion (UD), and Super UD. Image stability is further realized by the IS lens lineup (zoom and single focal-length lenses), featuring functionality that not only suppresses blurry images from camera shake but also helps you take natural animal photos as though they are in the wild.

New to the EF lens lineup is EF16-35mm f/2.8L II USM, a dust- and water-resistant zoom lens designed for improved peripheral image quality in wide-angle shooting. Advantages include optimized lens coatings and lens disposition for superior color balance and minimal flare/ghosting, plus a circular aperture for beautiful out-of-focus images. Precise contrast and image resolution without color bleed are enabled by aberration and chromatic correction from aspherical and UD lens elements, respectively. These optical and mechanical advantages are further assured by new measures like AF algorithms that enable fast and quiet autofocusing.
