John, manual Nikkors are indeed great!
I am discovering this, thank you
On the 50mm/1.2, shooting wide open may initially not seem that great with all the spherical aberration but it delivers magical portraits. Well worth the practice to nail the focus. If I had to live with only one lens, this would be it!
I can see that.
Great as-is, then flip it over, and it's a 1:1 macro lens
As Bjørn R. pointed out, the 105mm is simply fantastic. Most people favor the f/2.5 Ai version with it's rounded blades. The earlier Sonnar is preferred by some for smoother transitions at the cost of less pop. The 105mm f/1.8 Ai-s is top notch if you are interested in a more corrected lens (virtually no field curvature/CA), though many swear by the f/2.5's character. All of the 105mm's are cheap enough to buy a couple, test them, and sell off the one you like least.
I appreciate the info, but 105 is not a focal length that interests me as much ... though 200 and more becomes increasingly so.
