The EF lens mount is the standard lens mount on the Canon EOS family of SLR film and digital cameras. EF stands for "Electro-Focus": automatic focusing on EF lenses is handled by a dedicated electric motor built into the lens. Mechanically, it is a bayonet-style mount, and all communication between camera and lens takes place through electrical contacts; there are no mechanical levers or plungers. The mount was first introduced in 1987.
The Canon EF-S 18–55mm lens f/3.5–5.6 is a Canon-produced wide-angle to mid telephoto zoom lens for digital single-lens reflex cameras with an EF-S lens mount. The field of view has a 35 mm equivalent focal length of 28.8–88mm, and it is a standard kit lens on Canon's consumer APS-C DSLRs. In February 2017 Canon announced the new Canon EF-S 18–55mm lens f/4–5.6 IS STM with a smaller aperture, which made the lens 20% smaller according to Canon.
The EF 16–35 mm lens is a family of professional wide-angle lenses made by Canon Inc. The original version, the EF 16-35mm f/2.8L USM, replaced the EF 17-35mm f/2.8L USM lens, which had itself replaced the EF 20-35mm f/2.8L lens.
The EF 50mm lenses are a group of normal prime lenses made by Canon that share the same focal length. These lenses are based on the classic double-Gauss lens, with the f/1.8 being a standard six-element double-Gauss with an air gap and powers between element 2 and 3 and its faster cousins adding additional elements. The 50mm focal length, when used with a 35mm film or full-frame sensor, has been widely considered to match the perspective seen by the human eye.
Canon Inc. has produced seven different 24mm lenses for its Canon EF and EF-S lens mounts. Three have been discontinued after updated replacements were announced.
The EF 24–85mm f/3.5–4.5 is an EF mount wide-to-normal zoom lens. It was introduced by Canon in 1996. The lens was originally sold with the Canon EOS IX, an APS film SLR, although it was fully compatible with Canon's 35mm film SLRs. The lens was available in two colour schemes; silver when sold with the EOS IX, and black when sold separately. The lens remained in production during Canon's shift to digital SLRs and was often included in press images of the Canon EOS D30. As of June 2010 it is no longer listed on Canon's North American product page.
The Canon EF-S 18–135mm lens is a standard to short telephoto telezoom for Canon digital single-lens reflex cameras with an EF-S lens mount. The field of view has a 35 mm equivalent focal length of 29–216mm. With its 7.5× zoom range, it is placed into the superzoom category. Canon offers further lenses with even higher zoom ranges, such as the EF-S 18–200mm lens.
