Product summary

Features

The EF 50mm f/1.4 USM is a 50mm prime lens designed for the Canon EF series cameras. It is compatible with the entire Canon full frame, APS-C and the APS-H DSLRs. Using an EOS M mount adapter the lens can also be used with an EOS M camera. At a retail price of $400 this is one of the cheapest 50mm primes that Canon offers. The other being the EF 50mm f/1.8 II lens.

The EF 50mm f/1.4 USM is a fast lens with a maximum aperture of f/1.4. This basically allows you to shoot with a much faster shutter speed and much smaller ISO in available light. The lens has USM (ultra-sonic motor) technology which ensures that the lens is very quiet when auto-focusing. The lens vignetting is present in wide f/1.4 aperture and improves when one stops down to f/2 or more. For a wide lens such as this it is quiet normal.

There are a total of 7 lens elements arranged in 6 groups. The diaphragm of the lens is made up of 8 blades which create a small aperture of f/1.4. It can also stop all the way down to f/22. The minimum focusing distance of the lens is 1.5 (0.45 meters) and has a reproduction ratio of 1:6.66. The diagonal angle of view is 46˚.The dimensions of the  lens are 2.9″ x 2.0″ (diameter x length) and the weight of the lens is 290 grams. The lens uses a filter size specification of 58mm.

This is ideal for street photography and low light photography enthusiasts looking to take advantage of the full frame AF points of a professional Canon DSLR.
