I have the following and love it:

--FM3A (new)
--24 2.8 AIS (bought new for $280--can't beat that)
--105 2.5 AIS (amazing lens)
--80 2.0 AIS (just as nice)
--135 2.0 (a bit heavy but makes for nice portraits from afar)
--50 1.2 (bought new for $350)

Love all of the above. 24 2.8 stays on the camera most of the time.
