for those who recommended 5D IV , what i am really missing by just going for the newer EOS R and not buying the 5D IV ? as far as i know ( and i dont know much in this field ) am loosing an excellent battery .. but almost everything else is the same basically ? and the RF mount should be fully compatible with the EF lenses as far as the reviews says . as much as i wanted to get the 5D i just feel it is getting older and that i am buying already outdated camera ... most likely i will be using it at least for the next 5-8 years ..
To me the EOS R seems a lot more like a MILC version of the 6D than a MILC 5D. The camera is pretty slow in some ways....the true, hitting focus burst rate with AF as a priority is 3 fps. the 5D4 is going to be a much better camera in shooting action, I would imagine. That may or may not be important to you, but I tend to find that people with kids wind up shooting action. I don't have experience with it's AF system though......the one on the 6D 1/2 leaves a lot to be desired.
for those who got both the A7RIII and D5 IV , hows is the compatibility of Canon lenses with Sony ? can i actually use my own lenses or do i have to get all new lenses ? are they close to the native Sony lenses in term of compatibility ?
Adapted lenses on Sony are great for landscape work, portraits in good light, still life shots. They are not great for action or shooting in low light in general. I think a lot of Canon shooters moved to Sony under the premise of dipping a toe and using their adapted Canon lenses. These users all wound up getting Sony lenses pretty quickly if they decided to stay.
I have a pretty complete Sony kit, but I do still adapt my Canon 24-70/2.8L II and 70-200/2.8 IS II, as these two lenses work really well on the Sony.
That said, in low light the 70-200/2.8L IS II will hunt for focus on the Sony in light levels that would give my 5D3 absolutely no problems.
