Canon EF portrait lenses
Canon makes several lenses for the EF lens mount and EF-S lens mount that are well-suited for portrait photography. These lenses may also be used for other purposes, often being suited for indoor sports photography as well, due to suitable focal length and wide aperture, though autofocus speed is an issue in sports photography that is less important in portraiture.
==Criteria==
Lenses suited for traditional portrait photography are medium telephoto lenses, in the 85mm-135mm range, which provide the desired perspective distortion in head and shoulders shots (compressing facial features), and have fast aperture, of 2.8 or faster, to allow shallow depth of field, focusing attention on the subject.
One can use other lenses, either with shorter focal length (particularly for full body shots), or longer focal length (particularly in fashion photography, to increase the flattening effect, or in very cropped facial shots). Other lenses can be used for artistic effect; one could use a fisheye lens, for instance, though this is considered neither traditional nor flattering.
