How does AF Adjustment work in K20D?

brucestrange · 12-17-2008, 10:00 PM

I have a question that I can't find an answer for. I probably haven't looked hard enough, but why do that when I can pick the brains of the forum members.

My question is my title. But I don't mean how do I use it, I mean how does it work? Is the sensor moved to accommodate the focus problem in the lens? Is there just a calculation adjustment in the camera's computer system? Also, does it affect infinity focus? Anyone who knows anything about the mechanics of it, I'd be thankful for your answers.

Have a look at my explanation attempt.

In terms of operating the camera, I do just have the mnemonic "+=more closer." (Of focus point)

The gramattical error's so I'll remember the words, not end up outguessing what the computer means.
