>>3959690>>The big advantage m43 in low light are lenses. You can shoot at f1.8 with near perfect corner sharpness, and very little vignetting. On everything larger, both will be severe,>No they will not. Not unless you're buying very old primes or very cheap primes.That's simply not true. When you buy very cheap ff lenses, you're outright outclassed. Even when you buy the most expensive ff lenses, you're still not on the level of mid tier mft lenses.

Olympus 25mm f1.8
https://opticallimits.com/m43/886-oly25f18?start=1RF lens needs to go down to f2.8 to finally get to the level where Olympus is at f1.8. Also check the link and look at the corner sharpness of 25mm f1.8, and compare it with Canon's. In general the situation is as in this sample. At f2.8 you're already good for tact corners photography on mft, you can even get away at f1.8. On ff, you need to close to at least f4 to get this.
