I have an older Pentax DSLR (bought a combo with 2 zoom lenses). I also have some Pentax 35mm SLR lenses that will work with in a somewhat limited fashion. The price was good and I checked out the reviews of the camera and lenses thoroughly through some pro and serious photobug sources. I agree with Alpha the first point is the glass. Getting to the point where upgrading is on the horizon for me. In my case is are the newer Pentax cameras enough of a step forward or is it time to switch brands. What I really need for my use is better low light capability.
