I've just bought a Tarmron 17-50 for my Pentax K10, and am puzzled as to its true focal length? Is it acually 17-50 in 35mm film camera terms, or do I have to allow a crop factor for my camera? If this is the case, as I suspect, what would it be, compared to 35mm?

I hope to add a Tamron 28-300 or 70-300 at some point. Again, what would be the focal length of these lenses be in 35mm?

Thanks for any help offered
