Re: Nice summary but the supplement needs improvement

I agree with your 2 ISO stops comparisons between M43 and FF. It's the only way to be fair. Comparing FF and M43 at same ISO (like many do) is pointless since to get equivalent pictures, FF will need 2 more ISO stops.

BUT... Sony FE lenses are f/1.8 for the 55mm, and f/2.8 for the 35mm. With M43, you would respectively need f/0.9 and f/1.4 for equivalence. But there are not suh M43 lenses and you can't get equivalence. Roughly, 1 stop is missing to M43 lenses.

If you had post DPR samples in good light I wouldn't have say the following, but since you draw low light comparisons, given existing lenses, it would make sense to compare M43 3200 ISO to FF 6400 ISO, IMO. And if you do so, Sony FF is better.
