Standard prime for Canon SLR

The Canon EF 50mm f/1.4 USM is a fixed focal length lens designed for Canon SLR cameras. Its wide f/1.4 maximum aperture suits available-light shooting and shallow depth of field. Two high-refraction elements with Gaussian optics reduce astigmatism for crisp images. A Micro USM motor enables fast autofocus with full-time manual override.

Photographers needing a fast normal lens

This lens suits users who want a bright 50mm perspective for portraits, street or low-light work on Canon SLR bodies. The 1.5 feet close focus distance allows tight compositions. Buyers who need a variable focal range for framing flexibility should consider a zoom lens instead. The 58mm filter thread accepts standard accessories.

50mm f/1.4 focal length and aperture

The 50mm focal length provides a 46-degree angle of view on full-frame sensors. The f/1.4 maximum aperture is the single specification that determines low-light capability and depth-of-field control. The lens construction uses 7 elements in 6 groups. Closest focusing distance is 1.5 feet. Diameter measures 2.9 inches.

Questions about this item

Should I choose the f/1.4 version or look for a faster aperture in this focal length?

This lens opens to f/1.4, which is the fastest maximum aperture Canon offers in a 50mm EF prime. There is no wider-aperture 50mm in the same mount.

What does the f/1.4 aperture actually give me when I am shooting?

It provides a shallow depth of field for subject separation and gathers enough light for handheld available-light photography without flash.

Does the EF mount limit the f/1.4 aperture or autofocus speed on newer mirrorless bodies?

The EF mount transmits the full f/1.4 aperture and the Micro USM autofocus works natively on EOS R cameras via Canon's EF-EOS R adapter.
