Hello everyone, I've been practicing with my Pentax k20d. Still new but getting out there. I'd love to hear your suggestions on what I should do to make the pictures better though. I noticed that the 15-55mm lens performs better out doors... How would the 100mm prime lens do in doors and for headshots and poetry??? Anyone use that lens? I think I might get that one next. Anyway, thanks in advance for your comments. #1 #2 #3. #4.
