Among the pre-AI lenses
...the "K" versions are preferred...they have AI optics and construction, just without the AI mount
...the "K" lenses also have multicoating...
...lenses marked H.C, S.C, P.C, Q.C are also multi-Coated but have pre-K construction and optics..."C" lenses' coating seem to give about 1/3 F-stop more contrast/brightness over the earlier non "C" version
From my experience:
The 50mm/F2 people like is the one with the rubber focusing knurl...it's the "K" version......
The pre-AI 50mm/1.4 to look for is the S.C
The 85/1.8 was never AI, though a "K" version was made and the optional Nikon AI aperture ring was available...
The 135/2.8 Q.C is VERY good, but it is considerably "heftier" than the later "K" and AI versions
The 135/2.8 K is VERY good
The 180/2.8 P.C is the old Sonnar optic version...the AI and later ED versions are gaussian optics
The 200/4 Q.C is very good...the one with the longer focusing knurl and closer focusing (7') than the earlier 200
The 300/4.5 H is much better than reviewers claim, if not as good as the later ED
Enjoy the hunt and good shooting...
