Spanning a popular and versatile range of focal lengths, the EF 24-70mm f/2.8L II USM is a Canon L-series zoom commonly thought of as the workhorse of lenses. Ranging from wide-angle to portrait length, this lens is also distinguished by its constant f/2.8 maximum aperture to benefit working in difficult lighting conditions and to afford greater control over depth of field. The lens is also characterized by its sophisticated optical design, which includes one Super UD element and two UD elements, which reduce color fringing and chromatic aberrations in order to realize a high degree of color accuracy and clarity. Three aspherical elements are also featured, and minimize distortion and spherical aberrations for improved sharpness. Additionally, a Super Spectra coating has been applied to individual elements to control flare and ghosting for high contrast and neutral color fidelity.

Balancing the refined optics, this 24-70mm f/2.8 also sports a ring-type USM and internal focusing mechanism to enable quick, quiet, and accurate autofocus performance, as well as full-time manual focus override. Additionally, this lens is weather-sealed and has a protective fluorine coating on the exposed elements for use in trying environmental conditions.

Standard zoom is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 38.4-112mm equivalent focal length range.

Bright constant f/2.8 maximum aperture affords consistent illumination throughout the zoom range and also affords greater control over depth of field for working with selective focus techniques.

One Super Ultra-Low Dispersion element and two ultra-low dispersion glass elements noticeably reduce color fringing and chromatic aberrations for high clarity and color fidelity.

Three aspherical elements minimize spherical aberrations and distortions for improved sharpness and accurate rendering.

Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.

A ring-type Ultrasonic Motor (USM), along with an internal focusing design, optimized focusing algorithms, and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.

Rounded nine-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.

Protective fluorine coating has been applied to the front and rear element to resist fingerprints and smudges and to make cleaning these elements significantly easier.

As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.

Zoom lock lever secures the zoom position at the wide end to maintain a compact form factor and protect the lens when not in use.

Q: 7. I have a 7D & am considering upgrading to 5D Mark III.Will the EF-S Lenses I have accumulated work at all on the 5D?I understood from a friend the S-lenses will work but produce reduced size image which some would consider counter-productive for a Full-sensor camera. Others told me they won't work at all.Which is it?

A: Dont mount EF-S type lenses on a full-frame camera. Doing so can damage the camera and or the lens as the rear element of the lens is smaller then EF series lenses and can cause the mirror in the camera to actually hit the lens. There are Canon users who have attempted to mount various EF-S lenses on various full-frame bodies. In some instances there may not be the issue mentioned above, but coupling them together would void your warranty. We at B&H do not advise mounting an EF-S lens onto a full-frame Canon camera.

Q: 8. extended warranty??
