>>3842485>but really the f4 zoom is not that much better.The 5D II is better at high ISO out of the gate. Loosing a stop of light isn't going to help the GX80.
>also the gx80 has ibis, so in certain situations it can compensateYou're comparing against an IS lens. The GX would be the better lightweight travel cam, but otherwise the 5D II takes this if stills IQ is the criteria.
>>3842543The 5D2, 5D3, 6D2, and RP suck on base ISO DR, with the latter two being a bit better than the former two. The 5Ds/sR is actually decent. The 5D4, 1DX 2/3, and R6 are very good. And the R5 is excellent, on par with Sony A7 bodies and the D8x0 line.
It's just the state of Canon tech over time. You can always work around it by bracketing two frames and blending in post. The scenes which require hard shadow pushes are all static landscapes any way.
