I have all of the N-series M645 lenses from 35mm to 210mm, plus the 80/1.9, A 120/4 Macro, A 300/2.8 APO and C 500/5.6 LD. The most frequently used focal lengths on my Mirex adapter are 55mm, 80mm, and then 35mm. The 35N is a very nice lense, and so is the 45N, despite what some people say about it - the only reason that I select between the 35/3.5N, 45/2.8N and 55/2.8N is focal length, they\'re all excellent lenses.
I use the 300/2.8 APO a lot, but not with the Mirex. I only recently acquired the 80 and 120mm macros, so I don\'t yet have much to say about them. I\'ll be using the 80/4 on a M645 Auto-Bellows for high mag macro, and the few test shots I\'ve taken with the 120mm show it\'s a really fine lens. For 80mm, I chose between the f/1.9 and f/2.8 according to the DOF I want to use and whether I\'ll be carrying around it all day or not.
Note that the \"N\" lenses are also part of the \"C\" series. For example, the official name for the 55/2.8N is \"Mamiya-Sekor C 80mm 1:2.8 N\".
