Amazing, how many versions!! First versions are 7-elemenr, very overkill...
The Nikkor-Q 135/2.8 (1966) uses only 4 elements and has a good reputation.
On the URL you provided, the Auto Rokkor-PF has amazing bokeh, judging by the dog picture.
are they just as good? I dont see any body doing comparisons like with the nikon stuff. Also, there arent any serial numbers on the lenses that I can see and no lookup like photosynthesis for nikkors. . I saw the one site that shows every minolta lens but not much descriptions of them. Still , great resource for those of us in transition from nikon to minolta.
All great manufacturers made great 135mm lenses, Minolta shouldn't be an exception. I own Pentax, Nikon and Canon system, all great lenses, wouldn't be surprised if Minolta teles are just great as well.
For example i have or had (# elements/groups in parentheses)
Nikkor-Q 135/3.5 (4/3) - sharp at all apertures, good bokeh
Nikkor 135/3.5 AI (4/4)- smaller, as sharp, contrastier
Canon 135/2.5 FD (6/5) - big, heavy, sharp, contrasty, nice bokeh
Canon 135/2.5 R (6/4) - big, heavier, soft contrast, great bokeh
Canon 135/2.8 nFD (6/5) - compact, sharp, contrasty
Canon 135/3.5 nFD (4/4) - compact, very light, sharp, bokeh a bit nervous
Carl Zeiss Jena 135/3.5 (4/3) - sharp, contrasty, saturated, great bokeh, but a bit heavy
Pentax SMCT 135/2.5(6/6) - perfect lens
All of them are fine lenses, some just slightly better optically than others, but the difference is very small.
