With the fast aperture of f/1.8, the 50mm standard lens is an excellent lens for those people who prefer sharp performance and a fixed focal length. The Canon EF 50mm f/1.8 II standard lens uses traditional micro motor not including FTM (full – time manual) focusing. The AF (autofocus) seems to be very fast. The Canon EF 50mm f/1.8 II lens utilizes linear extension system for focusing (it is very similar to extension tubes). An excellent sharpness is the main key feature of Canon EF 50mm f/1.8 II lens.

The front lens element does not rotate thus it is easy to use polarizing filters.  The Canon EF 50mm f/1.8 II lens is a relatively low cost lens with a minimum focusing distance of 1.5 ft / 0.45 m providing impressive maximum magnification of 0.15x. Because of its sharp quality and inexpensiveness, it is also called “plastic fantastic” and “nifty fifty”. The standard prime lens attributes 8 diaphragm blades and a filter size of 52 mm.
