Distinguished by its speed, the RF 50mm f/1.2L 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.

Canon RF 50mm f/1.2L USM Overview

Distinguished by its speed, the RF 50mm f/1.2L 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.

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.
