The discussion was about how a focal plane shutter can stretch, (elongate or squash) a moving subject depending if it is moving the same direction as the shutter curtain or not. I can't find any noticeable image degradation on any of my 6x6 medium format chromes of moving trains shot with my Hasselblad, due to using the leaf shutters in my lenses. And I use that camera and those lenses a lot in the studio and I don't see those problems there either. I don't have any unusual vignetting or edge sharpness problems (was that the question?). I don't have a focal plane Hasselblad body, so I can't do a direct comparison to my leaf shutter shots. BTW, leaf shutters flash sync at all shutter speeds which is one reason why so many people use them in the studio.
