Granted, but for wider than 50mm... and for f/1.2, 85mm and wider... all other aspects of the attempted design being equal... it will...
What does “attempted design being equal” mean? What is the rationale behind your stated cutoffs?
A short flange 50mm lens may be the same size as a long flange 50mm lens, but all else being equal in design goals, a 49mm lens will automatically be smaller for short flange than long?
I’m not an optical engineer, but can think of really nothing that works that way.
