front focusing issue? my imagination?
Oct 26, 2010

These shots/crops are from a Canon 7d with 85mm f/1.8 lens. In many of the shots taken at this game at f/2.8, there seems to be a slight front focusing issue. Looking close, the point of focus seems to fall a foot or more in front of the player's feet (see detail in the grass). What do you think? Am I imagining this? It's a new lens for me and the sharpness generally hasn't been what I expected. These were taken in AI Servo mode, AF point expansion.

If you do think there's a front-focusing issue here, would you try to deal with this with in-camera micro-adjustment or have the lens sent back for recalibration? If MA, how many units would you expect would do the trick? Any comments or advice would be much appreciated!
