Canon RF 85mm f/1.2 L USM DS Full-Frame Lens for RF-Mount {82}

Canon's 85mm f/1.2 with DS coating, built for portrait glass purists.

The RF 85mm f/1.2 L USM DS separates itself from its non-DS sibling through one specific addition: Defocus Smoothing coating applied to the rear elements. At f/1.2, that coating actively softens the transition zones in out-of-focus areas, producing a rounder, more gradual bokeh falloff than the edgier rendering a bare f/1.2 can generate. It's a deliberate optical choice aimed squarely at photographers who shoot wide open and care how the background behaves, not just how sharp the subject is.

The optical construction runs 13 elements across 9 groups, incorporating one aspheric element, one UD element, and BR (Blue Spectrum Refractive) optics that address chromatic aberration in the blue spectrum specifically. Air Sphere Coating handles flare suppression, and a fluorine front coating, combined with L-series dust and weather sealing, keeps the lens functional in demanding conditions. Minimum focusing distance is 0.85 meters, and the 82mm filter thread keeps filter options accessible. The customizable control ring lets you dial aperture, ISO, or exposure compensation directly on the barrel, which portrait shooters working in run-and-gun scenarios will use constantly.

At 1195 grams, this is a substantial piece of glass. What you're paying for is a f/1.2 aperture that's been tuned not just for light-gathering but for a specific aesthetic output, backed by Canon's L-series build standards.

Who It's For

Portrait photographers shooting on Canon EOS R bodies will get the most from this lens: the f/1.2 aperture and DS coating together produce a subject-background separation that's been deliberately refined for flattering skin tones and smooth transitions. Filmmakers and video shooters working in cinematic narrative production will appreciate the control ring for smooth aperture pulls and the way DS smooths bokeh in motion. Wedding photographers working in low-light reception halls can shoot at f/1.2 without sacrificing the polished background rendering that editorial clients expect. Fine art photographers focused on shallow depth-of-field still-life or beauty work will find the 0.85-meter minimum focus distance and the 28°30' angle of view give them precise compositional control.

FAQ

What does the DS coating actually do?

Defocus Smoothing coating on the rear elements softens the bokeh transition zone at f/1.2, producing rounder, more gradual blur falloff compared to the non-DS version. You get creamier background separation without the edge definition that bare f/1.2 optics can produce.

How does this compare to the standard RF 85mm f/1.2 L USM?

The DS version adds Defocus Smoothing coating for refined bokeh rendering at wide apertures. If bokeh quality is your priority and you shoot wide open regularly, the DS justifies the difference. The non-DS lens is sharper in its bokeh structure.

What's the minimum focusing distance?

0.85 meters (2.79 feet). At 85mm on full-frame, that's close enough for tight headshots without distortion, though you won't get extreme magnification for beauty work.

Can I change aperture from the barrel?

Yes. The customizable control ring lets you assign aperture, ISO, or exposure compensation to direct adjustment on the lens itself, which speeds up shooting when you're working fast and need quick exposure changes.

How much does it weigh?

1195 grams (2.63 pounds). It's a heavy piece of glass, which reflects the build quality and optical construction, but you'll notice it mounted on a smaller RF body.

Is this lens weather-sealed?

Yes. L-series dust and water resistance, combined with fluorine front coating, keeps it functional in demanding conditions. It's not submersible, but it handles spray and dust without issue.

What filter size does it use?

82mm. Standard size, so filter costs and availability aren't a concern.
