Wide-angle: the Achilles' heel of SLRs?
Because of the inability to place the rear element closer to the film plane (the mirror gets in the way) RFs are touted as having superior wide-angle results. We know that this is so in theory and that compromises had (and still have?) to be made with optical formulas in order to 'compensate and correct'.
But, I ask, is this still so, with computer technology determining, most efficiently, the lens formulas of today? In other words, is a top flight Nikon wide angle (say 20, 24, of 28) inferior in any way to a Leica RF lens of the same focal length? - David Lyga
