Canon - EOS R6 Mark II vs OM System - OM-1 Mark II

The EOS R6 Mark II edges ahead on the Mars Score (46 vs 42.8), but the 3.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the EOS R6 Mark II if you care most about megapixels and sensor size. The biggest gaps in its favor are megapixels, sensor size.

Pick the OM-1 Mark II if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight.

Both ship with comparable max video, in-body stabilization, af points, 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.
