Best autofocus guide for 5DsR?

[Bazsl]

Canon has published an autofocus guide for the 1DX and another for the 7D Mark II but none for the 5Ds and 5DsR. Which of the two is closest to the 5DsR autofocus system; the 1DX guide or the 7D Mark II guide? Thanks.

The 7D Mark II is in many ways a crop-frame 5D Mark III. So I'd try the 7D2 publication first and see how well it matches the way your 5DsR works.

This is the one they suggest for 5D III owners.

It is likely the same for the 5Ds and 5DsR.

That's one vote each so I'll read them both. 🙂 Thanks.

Having the 5DsR, 1Dx, 7D2 and the 5DIII, the 5DIII manual would be the same from a AF perspective.
