What I want to know is if the em1 3 in high res mode can compete with the ff sensors -low light ,noise and dynamic range .
(Assuming the shot is possible,static object ect...)
If you are comparing m4/3 high rez mose to FF, you would be comparing with the 40+MP D850 class camera, not the 24MP D750 class camera.
If the pixel size is the same and sensor technology similar, I think m4/3 and FF would be similar in low light capability and DR.
But not against something like the Nikon D750, which is supposedly a VERY GOOD low light camera.
But to do that, the D750 is only 24MP, not 40 like the D850.
Similar 24MP to m4/3 20MP, but on a larger sensor, so the pixel size is larger.
Low light with the D750 vs. high rez with the D850.
The Z6 and upcoming D780, both at similar 24MP, but newer sensor, should be even better at low light.
