Design and Build

The Canon RF 50mm f/1.2L USM lens boasts a robust build quality that’s characteristic of Canon’s L-series lenses. The barrel is made from high-quality aluminum alloy, providing a solid feel in the hand while also resisting corrosion. The lens features a weather-sealed design, ensuring it can withstand harsh environments and extreme temperatures.

Optical Design

The RF 50mm f/1.2L USM lens employs an advanced optical design featuring 15 elements in 11 groups, including two high-precision aspherical lenses, one UD (Ultra-Low Dispersion) element, and four large-diameter glass-molded aspheric elements. This complex arrangement allows for exceptional correction of chromatic aberrations, distortion, and coma, resulting in crisp and sharp images across the entire frame.

Aperture and Bokeh

The lens’s f/1.2 maximum aperture is a significant advantage for photographers seeking to create stunning bokeh and separate their subjects from the background. The rounded 9-blade diaphragm helps to create a smooth, creamy out-of-focus effect that’s pleasing to the eye.

Autofocus and Image Stabilization

The Canon RF 50mm f/1.2L USM lens features a fast and accurate autofocus system driven by an ultrasonic motor (USM). This allows for quick and quiet focusing, making it ideal for capturing candid shots or portraits in various environments. Additionally, the lens includes a hybrid image stabilization system that helps to minimize camera shake and blur caused by hand movement or low light conditions.
