I was surprised to see how out of focus this fellow's nose is compared to his shoulder where I focused. I should have been fine according to an on-line DOF calculator. Could this be a bit of motion blur (mine, not his, he wasn't moving at all) combined with a bit of DOF (since the nose is likely a foot closer than the shoulder where I focussed)? Or does this mean that I need to buy a D800 with 70-200 ASAP All ideas welcomed.
