Yes..the old Minolta MC lenses were excellent, pity that the bodies....i.e. SRT101, SR7, SR1, seem to be so difficult to find, compared with Nikon bodies. The X700 is fairly common, but not of the same standard of construction as the earlier Minolta bodies, also the later MD lenses appear to be more "plasticky" than the earlier MC series.
-I'd argue for the Nikon FM3a - its hybrid shutter control makes it both a fully mechanical camera not reliant on batteries to do its thing AND a modern AE-equipped, electronic shutter control MF camera.
That aside, the build quality is terrific, handling is great and the built-in center-weighted meter works very well.
Yup, the FM3a is likely to become a classic somewhere down the line. (I guess one can argue that it already IS a classic, albeit a very recent one!)
