Canon RF 50mm f/1.2L USM Overview

By B&H Photo's

Distinguished by its speed, the RF 50mm f/1.2 L USM from Canon is a desirable normal-length prime due to its versatile focal length and bright f/1.2 maximum aperture. This fast design excels in difficult lighting conditions and also benefits working with shallow depth of field and selective focus techniques. The optical layout incorporates one UD element and one aspherical element, which help to reduce both chromatic and spherical aberrations in order to produce greater clarity and sharpness. A rounded 10-blade diaphragm also benefits bokeh quality to suit isolating subjects with depth of field. Complementing the imaging capabilities is an apt ring-type Ultrasonic Motor, which delivers fast, near-silent autofocus and full-time manual focus override. Additionally, a unique Control Ring is integrated into the lens design for intuitive control over exposure settings from the lens itself.

Normal-length prime is designed for full-frame Canon RF-mount mirrorless digital cameras.
Exceptionally bright f/1.2 maximum aperture affords extensive control over depth of field for selective focus applications and also benefits working in low-light situations.
One UD (Ultra-Low Dispersion) element is featured, and helps to minimize chromatic aberrations and color fringing in order to provide greater clarity and color accuracy.
An aspherical element is used to correct spherical aberrations and distortion for improved sharpness and accurate rendering.
Ring-type Ultrasonic Motor (USM), along with optimized focusing algorithms and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
As a member of the esteemed L-series, this lens has a weather-resistant design that protects against dust and moisture to enable its use in inclement conditions.
Rounded 10-blade diaphragm contributes to a pleasing bokeh quality.

Canon RF 50mm f/1.2L USM Reviews

The best lens I have ever used

By Eric
Rated 5 out of 5
Date: 2022-06-10

I am a prime lens shooter, I almost never use zoom lenses. And the 50mm focal length happens to be my favorite. That being said, this lens is the best I have ever used. And I am a bit of a lens snob. I've used over 50 different lenses over the years, including Zeiss. This Canon lens is just the best.

Beautiful in every way

I'm slowly swapping out my EF lenses for RF and 50mm was one of the first primes on my list. Not only is it better than the EF version, it feels great on my camera and is a joy to shoot. I was not a fan of the RF 50 1.8 so I'm thrilled with this as a replacement for the Sigma 50 1.4 EF mount I was using. Heavy, yes, but feels balanced and not as large as I expected. To be fair, the Sigma was a fantastic lens (will continue to use it on my 5DIV) but this is just a bit better in IQ and I love not having to use the adaptor. AF seems better than the Sigma as well with less hunting for eye/face in low light.

The perfect lens.

If you're looking for an amazing versatile lens, the RF 50mm 1.2 will be exactly what you're looking for. Whether you're looking to shoot videos or stills, this lens can get the job done. I have multiple RF lenses but you cannot beat the focal length of the 50. If you're on the fence, make the jump. This lens has basically replaced all other lenses in my bag. Great for portraits, product photography, & so much more. The autofocus is insanely quick, making it super easy to capture objects in motion. The build quality of this lens is impeccable, once you just hold it in your hands you'll have absolutely no buyers remorse. Feels like you're holding a precious gem.... But useful of course. Quite hesitating, this is the lens you need.

I have the RF 70-200, the RF 15-35...this lens might be better than both. I went out the other night and shot without a tripod, 1.2 and while most of the image was softer, the focus is SHARP. Beautiful bokeh, and sharp. Can't say enough good things about this lens. It's heavy, but about the same as the 15-35

Super sharp

Probably lives on my camera 90% of the time. It's one of the sharpest I own.

Love, love, love it!

Amazing photos with outstanding sharpness. Lighter than my 85mm DS but just as sharp. My favorite lens at the moment.

Buying Cine Lenses for Canon. Does this lens have a long focus throw? Does this lens have smooth F/T Stop transition, instead of "click" stops? For smooth transition of focus and depth of field?
Asked by: al
Sorry but this is not a cine lens. It is all electronic control with no scales. It would not work on a pro set for the assistant would have no way of controlling the focus or stop. If you want a Canon cine lens here is the link. https://bhpho.to/2A5NLe5

Why would a premium ‘L’ class lens like this Canon 50mm f/1.2 omit image stabilization in its design? This seems to imply that image stabilization might degrade the performance, or am I overthinking this?
Asked by: David
Certainly, this would have been technically possible. However, this particular lens is large and heavy compared to other 50mm lenses, consisting of 15 elements in 9 groups. Adding IS would have increased both size and weight to an already large 50mm lens. Fortunately, some of the other answers here demonstrate too why IS is not that important on 'fast' glass like this, especially if you have one of the new bodies with IBIS.
