Voigtländer - APO-Lanthar 50mm f/2 SE vs Voigtländer - Nokton 40mm f/1.2 SE

The APO-Lanthar 50mm f/2 SE edges ahead on the Mars Score (57.6 vs 54), but the 3.6-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the APO-Lanthar 50mm f/2 SE 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 Nokton 40mm f/1.2 SE similarly doesn't 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 don't 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 tells you both are well-rounded; the differences are about trade-offs, not quality.
