Basically, if the seller says it is for Pentax, then it is. The only thing you need to be aware of is the difference between m42 screw mount versus k-mount (google is your friend here). K-mount is what your camera has, although there are adapters to use m42 screw mount lenses. If the seller doesn't specifically use one term or the other and it's not otherwise obvious (eg, all lenses listed on the aforementioned site - the K, M, A, F, FA, DA, and DFA series - are K mount), feel free to ask the seller. If they don't know - don't buy the lens. If they can't tell you what kind of mount the lens has, then clearly, they've never used it, and have no idea if it even works.
