I don't know whether it's still the case, but one used to be able to find the AI version of this lens dirt cheap. Some years ago I bought one from KEH in bargain condition (perfect looking, but maybe a bit stiff in focus) for something like 25 bucks, and later got one at a yard sale complete with a minty looking FG-20 for $5. A really nice lens, robust and well behaved. These days, since "normal" is closer to 35 mm. I don't use mine much on DX digital, but the above photos remind me that I probably should.
I'm certainly no hot shot photographic artist, and have always tended to favor normal perspective. This is a lens that performs well with no surprises. Here is a picture of what I saw.
e.t.a. that last sentence should have quotes around it. It's what I presume the lens says, not an invitation to see a picture which clearly is not here.
Should be interesting on DX where field curvature should be absent with a nice portrait focal length.
