Canon 2515A003 EF 50mm f/1.4 USM camera lens

Standard 50mm prime for Canon EF cameras

This Canon EF 50mm f/1.4 USM lens is a standard and medium telephoto prime built for full-frame and APS-C EOS bodies. It suits photographers who need a compact, bright lens for portraits, low-light scenes and everyday shooting. The ultrasonic motor delivers quick, quiet autofocus while full-time manual override lets you fine-tune focus instantly. Buyers who want zoom flexibility or wider angles should consider other focal lengths.

Maximum aperture of f/1.4 for shallow depth of field

The defining specification is the f/1.4 maximum aperture, which gathers significantly more light than slower kit lenses and creates a shallow depth of field for subject separation. An eight-blade diaphragm produces rounded out-of-focus highlights. The optical design uses seven elements in six groups, including two high-refraction elements and Super Spectra coating to reduce flare and astigmatism. Minimum aperture reaches f/16 for extended depth when needed.

Compact 290g build with linear extension focus

Weighing 290g and measuring 73.8mm by 50.5mm, the lens adds minimal bulk to a camera bag. The overall linear extension focusing system moves elements internally without rotating the front filter thread, so polarisers and graduated filters stay aligned. A 58mm filter thread accepts standard accessories. No focus-distance scale is provided, and the micro USM motor draws negligible power from the camera battery.
