List of EF-S lenses

The EF-S lens mount is a relatively new offering from Canon, so the selection of available lenses is limited compared to the full EF range, but it is backward compatible with the EF mount, and can therefore still accept all EF lenses. The variety of EF-S prime lenses is very limited in comparison to EF-S zoom lenses, with three primes to nine zooms. EF-S lenses are very popular due to their lower cost and zoom lenses are preferred by amateur photographers. As of April 2017, no EF-S lens has been produced with the designation or with , and only three EF-S have been produced.

An EF-S compatible body, the Canon EOS 400D, with open lens mount

An EF-S compatible mount close-up, from the Canon 30D. Note the circular indent inside the mount, which corresponds to the raised ring on the lens.

By design, it is physically impossible to mount EF-S lenses on EF-only cameras. This is because the increased proximity of the lens to the sensor means that on full-frame sensor or 35mm film EF cameras the lens itself would obstruct the mirror’s movement and cause damage to the lens and/or camera. While it is possible to modify the lens such that the physical obstruction is removed, allowing for mounting to EF mount cameras, the rear of the lens would still obstruct the mirror. An additional reason is that the lenses produce a smaller image circle of even illumination (circle of no vignetting). An EF-S lens alignment mark is indicated by a small white rectangle, whereas the EF employs a small red dot. The lens will insert into the body when the alignment marks on each are matched, and the lens can then be rotated and locked into the operating position. EF-S camera bodies have both EF-S and EF alignment marks, while EF bodies have only EF marks. Some have reported success attaching EF-S lenses to full-frame bodies with the use of an extension tube; however, this does not eliminate the vignetting problem, and also removes the lens’s ability to achieve infinity focus. Also, attachment of EF-S lenses on EF bodies can often be accomplished by removing the small plastic ring seen in the photo above. Although vignetting is still an issue, photos can be taken, and infinity focus achieved. This modification comes with caveats, one being that on some lenses, like the EF-S 10-22mm, at the 10mm setting, the element protrudes too far back toward EF mount camera bodies.

The 10D, D60, and earlier cameras share the EF-only mount with the full frame EOS camera bodies, and also with the APS-H size EOS camera bodies (1D series prior to the 1D X), despite having a smaller sensor and therefore a smaller mirror.
