andnowimbroke, I almost believed that, then I thought back to all the Nikon rifle scopes I have owned and how they always had problems, one of which was recoil float and accuracy. So I knew what you said about Nikon just couldn't be true.


pilooo I can relate to that. The primes work very will with adjustments.


I re did all the test today, and I tested my 7D with it as well. The 7D performed similar, however the results aren't as consistent with the 7D as they are with the 1D Mark IV. (what I mean is comparing them side by side on the same lens you can see how much more accurate the 1D IV is).


I think there is some ratio or curve in play here (that andnowimbroke mentioned), that Canon maybe does take in to account. Even though the 1D Front Focuses at 70mm and Back Focuses at 200mm, the pictures taken at that those lengths almost all had an acceptable focus for the exact point of focus. (meaning it feel within the dof) What really varied was whether the DOF fell in front of or behind that point.


If I didn't get anything else accomplished in the two days of messing with this, at least I know what to expect of the 70-200mm F2.8L II.
