I guess I'm full of questions tonite. Went ahead and just bought a new to me K1000 off ebay and, of course, it comes with the standard 50mm lense. I want something more versitile. Is there any advantage to getting seperate lenses for different applications, like a 28, a 35, a 50, a 60, and an 80, for example, or will a good quality zoom that works from 28-80mm serve me just as well? What should I look for? Sigma? Tokina? Vivitar? Pentax? Thanks again.
