There's a real EBay bargain listed, $32 USD for a pair of Carl Zeiss Jenna Tessa 50mm/2.8s that "need to be adjusted for infinity focus".
Click here to see on Ebay
How difficult would that adjustment be, would a novice be just as likely to ruin the lens?
PS - hope this isn't off-topic |

I'm sure you're right, I just looked at the price guide and it seems to often go for 50 or 60 bucks.
Ebay listings in Canada seem to start at around $30, there aren't many steals on ebay.ca. |

Have you checked the repair section of our forum?...bargains are hard to come by down here too ....I think 2 tessars for $32 is not a bad price depending of course if you can fix them.

Oops I should have started there, there's a detailed discussion about this lens.
Lots of discussion of how tricky it is to re-assemble and get infinity focus right  |

Both lenses are tampered badly if not reach infinity focus well. I bought and sell many of them I did never find any with infinity problem.

I've never taken a lens apart before, and I'd hate to break something that used to work. Maybe the next time something is listed trashed/dirty/fungused "for parts" I'll buy it and give it a try, at least that way I can't make it any worse then it used to be. |

Good idea to start to learn on 'ready for trash' lenses.
