I have a question about using Manual mode and AF on the camera and the lens itself.
I would expect the dedicated professionals would go Manual all the way with RAW, but maybe I could be wrong in this assumption.
Please advise me of the following:

Do you
1. Dial M, use M on the camera and M on the lens
2. Dial M, use M on the camera and AF on the lens
3. Dial M, use AF on the camera and M on the lens
4. Dial M, use AF on the camera and AF on the lens
or some other combination I can't think of at present?
