Canon EF 50mm f/1.4 USM Lens

The Canon 50mm f/1.4 prime lens meets the demands of photographers who require a fast, low-light work horse with high quality optics and a superior build quality at an affordable price.

This lens features two top-quality refraction elements and high end Gaussian optics that create sharp and contrast rich images with very little lens flare. The eight blade aperture, which offers a very fast maximum aperture of f/1.4, creates a very wide ranging depth of field that allows for rich and full background blur effects when necessary.

Additionally, the 50mm f/1.4 is light and small making it the perfect traveling workhorse lens. Many photographers use this lens as an all around full body portrait lens. It also makes a great backup lens.

Moreover, the 50mm f/1.4 has a surprisingly low price considering the quality of the optics, ultra fast aperture and the nature of the images it produces. This lens is a valuable asset to many amateur photographers and works well as a backup lens for some professionals.

What Users Don’t Like About This Lens

Some people have had autofocus problems with this lens. Problems range from inaccurate focusing to complete failure of the USM system. Normally, the lens functions fine after servicing by a Canon technician. Additionally, the corners of images become light on 1.6x field of view crop factor camera bodies. This image quality issue only occurs at apertures f/1.4-f/1.6. Wide open, this lens also produces a softer image than higher priced Canon prime lenses. At f/2.0 however, images are crystal clear, sharp and high in contrast.
