I use the 5DS R and 7DII for bird photography. Birds in flight are just a small part of what I take, spot-on AF and high resolution are the most important features for me. So, would the 5D IV be an upgrade or an addition (I sold my 5D III, regretfully, a few months ago)?
Whatever the Dilberts say about the Mk IV, it does have some very nice features for us birders and nature shooters. The new focussing system from the 1DX II with greater f/8 capability is a real plus, especially if it is improved generally. The possibility of tweaking focus via the new DPAF could be exciting if it is able to get those just out-of-focus shots sharp. The downsides of the DPAF are huge files and possibly not being able to use DxO on RAW. Better DR at iso 400-800 would be a plus.
So, there is now a dilemma. I much prefer the 5DS R to the 7DII in terms of IQ, but like having it as a back-up, which can be used for action photography. I don't want to lose the very sharp resolution of the 5DS R, enhanced by its not having an AA filter. So, it's waiting for the hands-on reviews of the 5D IV.
