Well, <expletive deleted>!   Now I remember your saying that, Gary.  Every 
exposure I made yesterday was focused to where the shimmer just disappeared...

Guess I'll have to go out and shoot a test roll, and take copious notes, 
cause I wanna KNOW for sure.

Is it possible that it differs from body to body, with minor differences in 
lens mount-to-film plane distance?  Would probably have to be a MAJOR (out of 
tolerance) variation to have a noticeable effect, eh?
