I have a couple old tele lenses that I am looking to get rid of.
The First is a 400mm Quantaray T mount f5.6 (manual stop down). This lens is actually not too bad once you stop it down. Probably the easiest way (on the wallet) to get to 400mm. Lens is in very clean condition with case and hood. I'm looking for $65 for the lens, or $70 with a Pentax T mount adapter.
Second is a Vivitar 300mm f5.5. This lens is very clean, I can only see a couple small rub marks on the body, other than that it looks just about new. Has a built in tripod mounting collar. This is one of Vivitar's "adaptall" type lenses. It is not compatible, but uses a similar kind of system. The adapter which is included is a M42 adapter. The auto pin has been removed as it prevented manual stopdown on my K100D. I'm looking for $30 for this one. Sorry no pics at the moment, if you would really like some I can try to get some but I am short a camera at the moment.
