Hi, I'm new to theSLR camera world, and recently bought a Pentax *ist DS body and 18-55mm lenscombo. I'm very happy with it so far, and have learned a lot about photography from lurking on this board. Now I'm ready to buy a zoom lens to compliment the default 18-55mm lens, but I really don't know what to look for.
According to the review, this camera is compatible with Pentax K, KA, KAF, and KAF2 mount lenses; screw mount lenses, 645, and 67 series lenses (adapter required)
Can somebody explainwhat mountis better, and what the differences are? What should I be looking for in a beginner-grade zoom lens?
Thanks a lot, mutty
