Excellent comparison images, Wayne.
I have yet to see PS'd images that match the qualities offered by
dedicated SF lenses.
The Mamiya SF lens was so special it almost made me keep my RZ system.
I still have an eye open for an RZ 'steal deal' so I can get another
one. Though it would have to coincide with extra $$ in the account so
the challenge is substantial. ;o)
