Whoa, thanks for the suggestion! Exactly what I was looking for! What is, (in your opinion) a relevant difference in low ISO (or EV stop). I think DxO suggests a 25% difference to be relevant, do you agree?

Looks like the Pentax K1 II looks like the perfect fit for me (price, resolution and

Also, a few more questions:

Is it a good approach to also look at specific ISO values to compare the noise? For example, with my old Nikon D200 I wasnt able to go over 1600 in auto-mode, but all in all I was able to get decently exposed shots (with a f/6.3 or 5). Could have been better ofcourse, but I think an ISO up to 6400 will be able to handle all my ISO needs for my wildlife shots (defintely if I also would be able to use a flash+betterbeamer for fill in). Would comparing @6400 not make more sense, than the a general score or a score at their highest values? I think it definitely use the higher ISO values, but those would not be a priority I think. The Pentax K1 II looks like an absolute winner on that field (but sadly a too slow fps to be a pick).

is there a formula (or rule of thumb OR detailed info) to convert FF to a certain cropped mode (for a certain camera)

What amount of noise would be a good value to look at (Dxo sets it at 30db I think), and what about a good value if you include post processing noise reduction.

To conclude, I'm looking into a new DSLR for wildlife photography, and my father already has a whole set of expensive Canon lenses which I can use. I only included Nikon in this comparison for reference, but it seems I dont really have to worry about them. They are not better than my favourites, the Sony A7 III, A7R III and A9 and Canon EOS R.
