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 (65.4 vs 60.8), but the 4.6-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 single most decisive one: Weight — 140.00 g less. 950 vs 1090.

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.
