I don't really like the 80, but it is purely from the angle of view aspects, for me the 110 is a little better, I really like the 210f4. Kind of wish I had a 45 and maybe the 24. I do have one of the old Russian 30mm lenses and it is OK, but I would probably skip it next time in favor of the Mamiya 35 or 24.
I would like to get the 200 APO and maybe the 150 APO but I can't really afford them right now. I have the 150f4 but have not used it for anything so no real comments. Same applies to the 55. I do also have the 500f5.6 which is pretty nice for a giant of a lens.
