This topic just came up recently in another thread and it got me wondering myself. What makes the bokeh of say Mamiya RF lenses different than that of a MF SLR (Bronica, Mamiya, Hasselblad)? I own and use almost exclusively the Mamiya 6 with all three lenses. And I do notice what is sometimes described as a "hard" bokeh with the Mamiya RF lenses. Some say it's "un-pleasing." I think it's unique, and the part of the image that is actually in focus to me appears sharper than SLRs. But why are they different? And what are your interpretations of each? I'm only interested in talking about the bokeh of MF RFs vs. MF SLRs, nothing else.
