So, here's a German telephoto prime lens for sale. I don't know much about it. It lists for about $140 on ebay but sells for about $30 (lol). I've never shot with it, so I can't tell you the IQ from it. The lens is in great condition. I picked it up from an antique store and bought the Nikon 105 shortly after. So here it is. $20 shipped. Can't beat it if you're using a MILC without a lens in this focal length.
