AF tunning what actually happens?????
Jan 24, 2014

What actually happens when one setts AF tune in camera settings?

1. AF sensor is moving

2 Camera CPU with software communicates with lens CPU and makes point of AF changes and if so

how all of that knows since AF system will be locking on most contrasting parts anyway

or any other stuff happens.

Is there anyone that can explain what actually happens.
