Conclusion from DxOMark:
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.
