lens compatibility

hi, sorry if this is a stupid question.
i currently have a PENTAX K100D SUPER and have two lenses for it.
sigma 18-55
sigma 70-200

if i bought any new pentax camera, would these work with it?
(particularly the k-x?)

Hi Sara,
Welcome to the forum.
You will have no problem using any of your autofocus lenses on the K-x, including those you list.
That's one of the things Pentax prides itself with - backwards compatibility, even with manual focus lenses.

That's one thing you gotta like about Pentax... They stayed with 1 kind of mount. Not like the other brands... Right now i'm having fun with this 50mm lens from the 80s. <3 KX
