85 Canon RF 85mm F1.2 L USM

The Canon RF 85mm F1.2 L USM is a prime lens for Canon RF (Full frame) that covers 85 mm at f/1.2, weighs 1195 g and focuses as close as 0.85 m. Next to 4 other full frame Canon RF prime lenses in its focal range, it suits you if you shoot in low light or want a blurrier background. If you want something lighter to carry all day, look at the Canon RF 85mm F1.4 L VCM. If your body has no in-body stabilization or you shoot handheld video, every other one that does better on stabilization gives up brightness.

Worked out by code, not stated by a source

  • Read from the lens name: each maker marks the sensor size a lens covers (Sony FE/E, Canon RF/RF-S, Nikon DX, Tamron Di III/Di III-A, Sigma DG/DC); every Fujifilm X lens is APS-C and every Micro Four Thirds lens is Four Thirds.
  • Read from the lens name: Sony marks optically stabilized lenses OSS, Canon IS, Nikon VR, Fujifilm OIS, Panasonic O.I.S., Tamron VC and Sigma OS; a lens from these makers without the mark has no optical stabilization.
  • Prime or zoom, read from the focal length in the lens name.

  8. Lead for a pick1

Our pick or our take adds up the importance of each real difference, with these importances and thresholds: a gap smaller than its row's threshold is too close to call and counts as the same. They are our editorial choice, not a measurement, the same on every page, and they never read prices, sales or who sells it.
