The EF 70-200mm lens is a telephoto zoom lens made by Canon Inc. The lens has an EF mount to work with the EOS line of cameras.
The lens comes in four different versions. All four have a constant maximum aperture over the whole focal range and all four are L-series lenses.
All four lenses have an excellent reputation for providing optical quality comparable to various prime lenses at all focal lengths in the zoom range. The f/4 non-IS version, the most inexpensive L-series lens that Canon makes, is popular among weight-sensitive landscape photographers and hobbyists who want L quality without spending thousands of dollars, while the f/2.8 versions are popular among event and portrait photographers and photo-journalists. The IS-equipped lenses are sealed against dust and water and use circular-bladed diaphragms which maintain a nealry circular aperture when stopped down by up to two stops.
The most frequently pointed-out problem with this lens is the placement of the IS and AF buttons, that makes them prone to accidental flipping during hand-held shooting. Most photographers solve this simply by covering the buttons with a piece of gaffer tape. In recognition of this issue, the most recent of these lenses (the f/4L IS USM model) uses switches designed to reduce the incidence of accidental switch activation [1].
