Cannon EF Lenses

EF Lenses

EOS digital SLRs are backed up by the world's most comprehensive system of interchangeable lenses. From 8mm ultra wide angle to 800mm super telephoto, the 60+ lenses in the EF series cover all possible shooting requirements. See the world from new perspectives. Capture your vision through the eyes of EOS.

Wide zoom

Wide angle zooms allows you to make adjustments to the coverage of your shot for more creative control and broaden your perspective. Providing a choice of wide angle focal lengths ideal for everything from landscapes to confined interiors.

Standard zoom

These zoom lenses cover the most popular focal lengths, from wide-angle to telephoto. An essential part of any EOS camera system.

Telephoto zoom

Telephoto zoom lenses provide a range of focal lengths enabling you to get close to distant subjects or fast action sports. Telephoto zoom lenses offer a range of possibilities.

EF-S

Lenses specially designed for use with Canon’s APS-C digital sensors cameras. Canon engineers took advantage of the smaller sensor size to be able to produce smaller and lighter lenses for use with these digital cameras. EF-S lenses offer a range of focal lengths using the latest in optical technology.

Wide angle fixed focal length

Wide angle lenses have a greater angle of view, providing a broader perspective to capture grand vistas or scenes in close proximity. They also feature an increased depth of field ensuring more of the subject is in focus. With their compact design they are ideal for use on the move.

Standard and medium telephoto fixed focal length

For a more natural angle of view and perspective, a standard or medium telephoto lens is recommended. These lenses match how the human eye perceives a subject and are excellent for portraits.

Telephoto fixed focal length

Telephoto lenses allow you to get a closer view of subjects that normally may be difficult to get close too such as wildlife or sports. Providing long focal lengths and fast apertures these lenses allow shooting in a wide range of conditions.

Macro

To bring small things into full-sized view, select from one of the lenses in this category. Macro lenses can uncover detail that would be impossible to detect by the eye and give new perspective to extremely minute subjects such as insects or the petals of a small flower.

Tilt and shift

These special lenses with their tilt and shift movements further expand photographic possibilities. Tilt movements allow you to obtain a wide depth of field even at the maximum aperture and still keep the entire subject in focus. Shift movements correct the trapezoidal effect seen in pictures taken of tall objects such as buildings, so that the subject does not look distorted.

Extenders

Extender is Canon's name for a teleconverter. These high-performance accessories multiply the effective focal length of an attached lens by 1.4x or 2x. For example, a 200mm lens with Extender 1.4x has an effective focal length of 280mm: with the Extender 2x, this increases to 400mm. Extenders are only compatible with selected EF lenses, including the EF 70-200mm f/2.8L USM, EF 70-200mm f/2.8L IS USM, EF 70-200mm f/4L, EF 100-400mm f/4.5-5.6L USM, EF 400mm f/4 DO IS USM and fixed length L-series lenses of 135mm or higher.
