Canon RF 50mm f/1.2L USM Lens tested at DxOMark website. According to test results the RF 50mm f/1.2L USM lens achieved an overall score of 38 points.
The lens tested on the Canon EOS R, the company’s 30.3Mp full-frame mirrorless camera, and it compares well with Canon’s previous 50mm f/1.2 lens.
This score puts the Canon RF 50mm f/1.2L among the top five 50mm lenses in DxOMark’s rating. However, it’s clearly below the score of lenses that costs much less, e.g. the Sigma 50mm f/1.4 DG HSMand the Zeiss Milvus 50mm f/1.4.
As part of Canon’s L series, it is designed for professional photographers who want a bright standard prime lens. The Canon RF 50mm f/1.2L is a remarkable lens, made to showcase the capabilities of the RF mount.
Canon has constructed the lens from 15 elements in 9 groups, with 2 large-diameter ground aspherical lens elements, and 1 glass-molded aspherical lens element for better image quality into the corners of the frame when the aperture is wide open.
There isn’t a huge pool of f/1.2 50mm lens to compare the Canon RF 50mm f/1.2L USM against, and most of its competitors have a maximum aperture of f/1.4 or f/1.8. If optimum image quality is your major concern, then the Sigma 50mm F1.4 DG HSM A makes for a better choice, although it can’t be mounted directly on Canon’s mirrorless cameras. However, if you need the extra 1/3-stop of light, then the RF lens makes a good solid proposition that is a step up from the older Canon EF 50mm f/1.2L USM.
