If it's K-mount, sure it can be mounted on the K-x. Unless it's the screw mount M-42, then you need a screw mount M42 to K adaptor.
To be accurate, shoot a bigger image of the lens mount to refer.

not just bigger picture....preferably take a shot of the metal mount at the back so that we can access if it's bayonet or screw mount.

It's a M42 screw type mounting....http://cgi.ebay.com/SIGMA-ZOOM-K-1-4...item27b208028a

Thanks Wtay0001. I do have an adapter to fix M42 lenses to K mouth, but i dun think it can be fitted on to the lens.

Here is the photo:

Strange, the shot you share indicate your lens is a bayonet mount (K-mount). You should be able to mount it directly to your existing camera without any problem.
