Pardon me, I'm not a camera person. I'd just like to know what kind of camera these lenses fit onto so I know what to list them as on CL or that big auction site. (forgive me if that's crass) They appear to have no markings at all except "wide angle" and "telephoto" and also the "made in japan" on the other side. Any clue? http://thejoyofliving.net/ebay/IMG_1849.JPG http://thejoyofliving.net/ebay/IMG_1850.JPG http://thejoyofliving.net/ebay/IMG_1851.JPG http://thejoyofliving.net/ebay/IMG_1852.JPG I'm really just trying to figure out if they're worth anything, if they're some generic "fit all" from the 80s it might not even be worth listing. Thanks for your help in advance!
