Lex, Check out the Ansel Adams book "The Camera", I believe the reason is
covering power. The small lenses couldn't hope to cover that much area.
Talk about extreme vignetting(?SP)!
There is a good example in "The Camera". It contains a photo taken with an
8"X10" view camera with markings on it as to what would happen in other
formats down to 35mm at, I think, the same (maybe equivalent) focal length.
I don't own the book so I can't look it up, but I know it's there. The
picture is of a large living area of Ansel's house.
