Canon EF 50mm f/1.2L USM — Bright Prime
This Canon EF-mount prime lens covers the full-frame format with a fixed 50mm focal length and a maximum aperture of f/1.2. It is built for photographers who need shallow depth of field and strong low-light performance in a weather-sealed L-series body. The ring-type ultrasonic motor provides quick, quiet autofocus with full-time manual override.
Aperture Range f/1.2 to f/16 — Depth Control
At f/1.2 the lens delivers very thin depth of field for subject isolation and works in dim conditions without raising ISO. Stopping down toward f/16 increases depth of field for landscape or group work, though diffraction gradually reduces peak sharpness at the smallest settings. The closest focusing distance is 0.45m (1.48 ft), which limits close-up magnification.
72mm Filter Thread — Compatibility Decider
The front filter thread measures 72mm, so circular polarisers, ND filters and protective glass must match that diameter. Buyers using smaller or larger filter systems will need step-up or step-down rings, adding cost and potential vignetting. The lens does not zoom, so the thread size never changes during use.

Questions about this item
Will the 50mm f/1.2 L lens autofocus on an older EOS film body that I still use?
The ring-type USM motor drives autofocus on any Canon EF-mount camera, including earlier film models, and full-time manual focus is always available by turning the focus ring.
How can I confirm the lens is performing at its f/1.2 maximum aperture after mounting it?
Set the camera to aperture-priority mode, select f/1.2, and verify the viewfinder or LCD displays that value; the depth-of-field preview button will stop the rounded 8-blade diaphragm down to show the effect.
Does the box include a 72mm protective filter or must I buy one separately?
The lens ships with front and rear caps and a lens hood; a 72mm filter is not included and must be purchased separately.
