To close the story... I emailed the seller offering to keep the lens and spare him the return mailing cost if knocked $10 of the $16 it cost. Never heard back. Started a case w/ ebay, and again waited for seller to reply, and he never did. ebay resolved the matter. I sent back the lens at no cost and got my money back. It might have been worth it to me for $6 to see what it was like to dismantle an old lens, but it wasn't worth anything as a paperweight.

I did leave negative feedback since the seller never replied to multiple inquiries.

I got this lens rather cheaply on $bay, and it is still returnable, but I'm trying to figure if it's worth keeping even if I can get some money back. (I only paid $16 for it, but it was listed as fully functional.)

It's a Carl Zeiss Jena Tessar 50mm f2.8 from 1964. The aperture blades are clean and snappy, so that's good. The focus ring, however, is absolutely frozen. It will focus at about 5' but that's it.

Googling around, I came across this page to which almost everyone refers who has aperture problems. (It wouldn't hurt to get inside my lens, since there is some haze on one of the internal elements.) BUT, my CZJ has no screws on the back plate. The only visible screw is on the aperture ring. There are no little divots on the front of the lens where I can use a spanner to get at it from the front, so I'm guessing I'd have to use some sort of rubber stop and pressure to unscrew the front element.

So, is it worth keeping? If so, worth how much? Is it worth fixing? Or just get my money back? Thanks!
