Yes, Pentax and Nikon has kept their mounts, so old lanses do fit and can be used. But it is _not_ "more so" with Pentax, it is less so since Pentax did not bother to make their new cameras fully compatible with the whole point of the K-mount they once invented. On a Pentax DSLR you have to stop-down meter using old K-lenses since the new bodies cannot mechanically feel what aperture the lens is dialed in to, they do not have that little pin sticking in the lens on the cartridge side of the mirror, the camera house pin that feels the aperture ring on the lens. Probably because Pentax wants people to buy new lenses instead of using old ones, by making old lenses clumsier to use.
