P.J.: I did some investigation about that some time ago. I might be wrong, but I came to the conclusion that all the versions are KA. It is just that some resellers are not very careful with what image they post on the product page, and some post images of non-K-mount lenses (that don't have the "A" marking on the aperture ring).
But again, - one should pay a due diligence in verifying that. Igor Mon Dec 10 18:17:41 EST 2012 P. J.
