Leica - SL3 vs Sony - α7C II

The SL3 is the clear pick on raw spec strength, leading by 18.0 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

Pick the SL3 if you care most about megapixels and af points. The biggest gaps in its favor are megapixels, af points, max video.

Pick the α7C 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 sensor size, in-body stabilization, log profile, so those specs don't separate the two — focus on the differences below.

Bottom line: the SL3 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
