I just purchased my 1Ds MkIII, but I also use the same "L" lenses on my 40D. If there is the need for large micro adjustments (that's an oxymoron, I think), does this mean that the lenses cannot be focusing at their optimal level on my 40D? If this is the case, wouldn't it be better to have the lenses recalibrated by Canon?
My current assortment of lenses (all Canon): 24-70 f2.8L, 24-105 f4 IS L, 70-200 f2.8 IS L, 100-400 f4.5/5.6 IS L, 16-35 f2.8 L, 100mm Macro, 10-22 f3.5/4.5 (40D only)
