or from another thread
AF fine adjustment is the menu you need. On yours it allows a different adjustment for each lens, while on older models it is a one-size-fits-all adjustment.
On a camera body with Live View (which we can take to be perfect for this purpose) then do the following:
1. On a tripod, use LV to focus on a specific clear object a few metres away. Like a poster on the wall.
2. Once focussed, place a mark on the focussing ring (or on a piece of masking tape on the ring) to show where the exact point of focus is in relation to the centre line.
3. Defocus the lens completely by putting your hand in front of it and focussing on that.
4. Focus the lens again using normal AF, rather than LV.
5. Is the mark you made in LV now exactly aligned, or is the focus point slightly different?
6. Adjust AF offset until the two match exactly.
Once done the normal AF can be set to match the Live View AF and you have exact focus.
Let us know how. It goes.

I must confess to quite liking #11, albeit with a slightly tighter crop off the bottom, not much, just under where the blur starts to clear. I think its the way it frames the clarity beyond that i like. I could be wrong though, hence my sig
