Thanks. I've ran across that site a few times. I'll make sure to scour it for all of the information I can.
My head/meter is not AI. I have to "twist/twist" to get the lens to index. The lenses I have do not have the cut out on the foot that couples with the head. I don't change lenses much on this camera since the only other one I have is a zoom, but I've gotten so use to twisting to index that I was actually a little confused when I started using the Canon F1 and FD lenses.
