Just received an old Asahi Pentax K-1000 that's in pretty good shape. But all I have is the original 50mm lens. What kind of tripod, zoom or telephoto lens, flash, and filters should I get. I'm trying to keep the cost low. Since the camera was free, why go crazy. Thanks.

I just got my hands on a 25-30 year old Asahi Pentax K-1000 and am looking for a good zoom lens (28-100X for now). In the manual it talks about a Takumar lens. Do I need this to atach a zoom lens or UV/Skylight filter? And what is a Mount Adapter K? The manual is not too specific on these pieces. Thanks.
