Erwin, I'm having some difficulty understanding this. Is 'choosing the
location of the film plane' the same as what is commonly refered to as
'focusing' or is it something the lens designer does when designing a lens.
Because if it's the former it is the photographer or lens tester doing the
choosing (except off course at the min focus distance or (usually) at
infinity).
***
Choosing the location of the film plane is done by the designer and influences 
the image quality. When we photographers do focus, we try to position the 
projected image exactly on that film plane.
