Hi all,
Seeking the lens market AND the related info WRT Canon 1D X, I found some things which seems concerning:
1st, a note from Canon's Chuck Westerfall (it was quoted also here in some threads) saying:
Having in mind the above, this means that Canon 1D X cannot focus on the longer (telephoto) lenses which have an aperture smaller than f/5.6, say 6.3?
This includes (at least) the following lenses:
From Sigma:
50-500mm F4-6.3 EX DG HSM
150-500mm F5-6.3 APO DG OS HSM
50-500mm F4.5-6.3 APO DG OS HSM
28-300mm F3.5-6.3 DG Macro
From Tamron:
28-300mm VC F/3.5-6.3 XR Di VC LD Aspherical [IF] MACRO
28-300mm VC F/3.5-6.3 XR Di LD Aspherical [IF] MACRO
SP 200-500mm F/5-6.3 Di LD [IF]
...so, by buying Canon 1D X and having at least one of the above lenses and raking out the glass, one cannot use the AF anymore?

“AF is unavailable on the EOS-1D X if the maximum aperture reported to the camera through the electronic lens mount is smaller than f/5.6. This is a lower specification than previous EOS-1 series DSLRs. [...]"
