Canon - RF 50mm f/1.2L USM vs Sigma - 35mm f/1.2 DG DN Art

The RF 50mm f/1.2L USM edges ahead on the Mars Score (57.6 vs 51.9), but the 5.7-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the RF 50mm f/1.2L USM if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight, min focal, max focal.

The 35mm f/1.2 DG DN Art similarly does not carry a headline advantage on the popular specs — look at the full table for category-specific deltas.

Both ship with comparable weather sealed, optical stabilization, so those specs do not separate the two — focus on the differences below.

Bottom line: the RF 50mm f/1.2L USM is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
