Done!

Just bought a Vivitar 135mm f/2.8. It has large (ok, those would probably be considered giant) scratches on the edge of the glass, and some tiny ones in the middle. The tiny ones are fine, the large ones may be a problem. It was about sixty dollars less than what they are un-scratched, and no one else had bought it, so one would think it was probably not a good idea, but we shall see.

I have a few Vivitar lenses for the AE-1, and not being particularly knowledgable about photography in general, never realized they also made a Nikon mount. As does Tamron, etcetera. Which will not require an adaptor, since the D70 mount should, in theory, be the same. (Yay vintage!)

Watch me be ill-researched and wrong. Which is why I went for the broken and battered lens. (I'm not buying the unscathed one, anyway.)

It's funny, I never know anyone with any old Nikon lenses, so it did not occur to me. I wonder why? (No one has one, not that my train of thought was absentee of ideas on this issue for the last six years - that's less surprising.)

(I want to use my camera on specific trips this summer, but I'm not taking anything film as it will be much too heavy, plus I'd be heartbroken if I lost any of that gear. Dented and scratched substitute? Sure. Yes, I finally realized I would not magically finish up my full-frame dreams by May, and I would be left photo-less. Fair compromise.)
