Originally posted by ivanvernon Nice shot. Wondering your general views on the Mamiya 55mm. I have been using the Mamiya 80mm f 1.9 N with adapter on my K-1, and considering whether to buy some of the other medium format lenses, also for use on K-1, K-3, etc.
My best Mamiya 645 lenses are the 55mm/2.8 and the 80mm/4 macro. These are both superb. The Macro is unusually good at infinity as well as close up; I believe it has a floating element. These are all great on the Mamiya, as well as with 135 film, and on my Pentax K5iis as well. I also have the Mamiya 645 45mm, the 150mm, and an 80mm/2.8. The 45 is a bit soft at the edges on the Mamiya 645, less so on the K1000 obviously, and even less with the APSc sensor. I haven't used the other two lenses enough to state an opinion.
