Buying advice

Which should you buy?

These two are nearly even on the Mars Score (57.6 vs 55.3). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.

Pick the RF 50mm f/1.2L USM if you care most about min focal. The biggest gaps in its favor are min focal.

Pick the 24-70mm f/2.8 DG DN II Art if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight, max focal.

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

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
