DxOMark has just tested the new Canon RF 50mm f/1.2L USM lens for Canon full frame mirrorless cameras today. The Canon RF 50mm f/1.2L USM lens is one of the best selling RF mount lenses, currently US price is $2,099 at B&H Photo Video/Amazon/Adorama/Focus Camera. According to DxOMark, this lens scored 38, one of the best 50mm lenses.
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.
