There seems to be a lot more stipulations, with regards to completing a successful back focus adjustment, every time I read something on this thread.

Would probably help if Sony actually issued some definitive information!

Dominik, Yeah you might be right. I'm not planning to try it again though as its working.

I don't remember how I was set up when the procedure didn't work but its possible that I didn't even have the focus barrel pushed into place for auto. I usually leave the servo on and the focus barrel disconnected for manual. I'm just passing on what I was told by the Sony repair department though and when I tried all Auto it worked. I'm not really sure what I changed after talking to him.

Dominik has it right here. The only prerequisite is sliding the zoom switch on (with it at off position, the Flange Adjust will be grayed out in the Maintenance Menu, and thus inactive).

All the other settings will be taken care of by the procedure itself.

While we're at it: does anyone know what prerequisites are necessary for the Auto Black procedure to become active?
