So I got a bit excited the other night when I saw a lovely looking lens going cheap on ebay. I managed to snap it up for £15 inc postage. It's in great nick, no dust or scratches or dings. It has a screw on filter of some sort (not sure what). It's very pretty. But I have realised I'm not actually sure what it's for. So - what would YOU do with a Canon FD 135mm f3.5-32 lens? I'll get it on the NEX tonight and see what it can see.
