I almost never use my 45mm f/1.8 lens. The family hates having their picture taken (they think I'm a photo-terrorist) and I use my PL25 or Minolta 50/1.4 for low light. I told myself I'd keep it forever, along with my 100-300, but my 45 is almost never used. I'd like to get my hands one some old super-tele lenses for wildlife, and it wouldn't hurt to raise some cash. Should I sell my 45?
