Up for sale is a Asahi SMC Pentax-M 1:2 50mm Lens.  It is in great shape, fully functional and works great!  It comes with two Quantaray 49mm filters, one is just UV, one is DMC-UV.  It also comes with a rubberized Light Block/Shield or whatever it's called I don't really know.  This is also a 49mm piece and fits over the end and pops in and out depending on how much light you need to block with this lens.

Any questions just ask, thanks for looking!
