So, whenever I went to a garage sale or flea market, I casually looked for any older Pentax lenses that might be around. I never stumbled across one single lens. I never even saw a camera. Well, just the other day, a guy was selling an old Pentax camera (K1000) on craigslist with "extras". Turns out the extras were a 70-200mm f/3.8-4.8, a 100-300mm f/5.6, and a 50mm prime f/2, a lens cleaning kit, some filters, and a camera bag. Nice.
I haven't gotten to fool around with the longer range lenses, but here are a couple of shot comparisons with the 50mm prime (comparing to my 18-55mm f/3.5-5.6 kit lens).
I don't need to be a professional photographer to realize that the pics with the new lens are a whole lot better. The only problem is that with these new lenses (all of them), is that I lose the ability to autofocus. I don't know if that is going to hinder their use in skiing, when I like to bang out a bunch of pictures in a row and I can't be bothered to focus on every one. I guess time will tell. Right now, though, I can't think of any other way I would have rather spent that cash.
