Hi Whayne, You have covered all the bases well. I can have no idea what is best for you. I am getting on the ship for 2 1/2 weeks tomorrow and I can say that I have been using my 2 5D IV bodies with both TCs including at f/9 and been thrilled. I did do a session with the 1DX II on our last day at Bleaker and my success rate was a bit higher than with the 5D IV but I did stick with center AF point only with the 1DX II. And there was a ton of operator error involved. I will turn to the 1DX II on the really dark days on South Georgia. Whatever you decide, please remember to use my B&H link 🙂

I currently have 5DsR and 1DX and was considering whether to bother with replacing 1DX by 1DXII or 5D4. I know the AF is basically the same in 5D4 and 1DXII but 1DXII has dual cpu’s, dedicated AF cpu, higher res colour metering sensor and bigger battery for faster intial drive of mk II supertele’s. So to me a more logical comparison is 5D4 vs 1DX. Apart from 7fps vs 12fps, for action work especially bif, has anyone compared these two. I suspect AF with TC’s is a bit better with 5D4 (a fair bit better with 1DXII especially f/8 combos) and in low light 5D4 should be a bit snappier. Also is it better with low contrast subjects like 1DXII.

I don’t really want to give up 5DsR as I do. A lot of landscape too, but it’s also a very good birding combo, and I’ve found it’s AF to be better than 5D3 and not far behind 1DX in many situations. So it’s down to either waiting for 7D3, 5DsRII (late 2017 it appears), 5D4 or 1DXII or do nothing and just ain’t for the 600 f/4 DO next year :o)
