Thanks Horshack.

How much does the range vary? Instead of moving increment by increment can you take a jump to speed up finding the other end of the range?

It depends on the lens. On my Sigma 35mm f/1.4 the range is very small, only 4 AF tune units. On my 50G f/1.4 it's 9 tune units. You can jump around at any increment you'd like when trying to locate the general are of the range.
