What I want to know is:  which one will make a better 11x14 or 12x16" print?
Looking at screen pixels is not the final product, even though it does tell
us something.

I am especially interested in comparisons of prints made from the Sigma
Fovion images versus the new Olympus E-1 DSLR versus scans of film.  Also,
any other DSLR vs film scan prints.
