I wonder why they bothered with the 5ds. Why not just have one model to track? Does the 5d do something the 1D doesn't?
SILENT MODE. It beats the living S___ out of the 1DX for being quiet and that is a very important consideration at this level.
No kidding, not too mention how living macro shooters couldn't live without it
