(Mods, i accidentally posted this message in the general DSLR forums..but, couldn't figure out how to delete or move it. I certainly don't mean to spam. I just wanted the right audience to see this thread.)
There's a local camera store here in town that has been around forever and the owner has some leftover accessories from an estate sale. One of the items he's selling is a 400mm/6.3 telephoto prime lens for $30. It's an m42 screw lens ...but i can't really find any information on it. Can you guys help me out based on the image below and tell me if it's worth $30? (My gut feeling says to just buy it and try it out since its only $30.)
(Sorry about the crappy pic...i was using my iPhone and i guess had it too close.)
