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.

Questions about this item

What does the f/1.4 maximum aperture mean for low-light shooting on a full-frame Canon body?

The f/1.4 aperture gathers significantly more light than slower lenses, enabling faster shutter speeds and lower ISO settings in dim conditions while providing shallow depth of field for subject isolation on full-frame sensors.

How does the Canon EF mount interface affect aperture control and autofocus performance?

The EF mount provides full electronic communication for aperture control from the camera body and powers the micro ultrasonic motor for fast, quiet autofocus with full-time manual focus override capability.

What filter thread size and physical dimensions determine accessory compatibility for this lens?

The lens uses a 58 mm filter thread for circular filters and measures 73.8 mm in diameter by 50.5 mm in length, weighing 290 g, which determines compatible lens caps, hoods like the ES-71II, and filter systems.
