Abstract said:...the Samsung models are basically Pentax models anyway, but with a different Samsung badged lens made by that Schneider company (forgot the name). It also uses the same mount as the Pentax, so it should be able to use all of Pentax's lenses.
just as a point of clarification, the lens that comes with the Samsung is branded as a Schneider-Kreuznach, but it is actually a rebranded Pentax DA 18-55. Don't ask me why Samsung wanted to rebrand both the body AND the lens (and make them different from each other no less), but they did.
