Chinon 50mm f1.7 AF

Hello im new to this forums and new to Pentax as I am a Canon user. I picked a a K110d for a steal and building my arsenal of lenses! Anyways, I have done my research and have found many people using the Chinon 50mm lens, What I haven't found is one that has Auto focus. I just won one on ebay that is brand new with k-mount listed and showing the box as a 50mm F1.7 MULTI COATED CHINON LENS IN PENTAX K MOUNT BOTH MANUAL AND AUTOFOCUS. Anyone own this lens?
Any help would be great!
Thanks

Well, I have Auto Chinon MC 50/1.7, but it's manual lens. Focus is just a little bit soft wide open, but above that it's getting much better. It's VERY sharp already at f/4. Bokeh is great at all lower apertures.
Aperture ring is bit softer than those on Pentax manuals ("click" is a bit quiet), but lens itself is very solid and well built.
You can see few examples in my gallery, link is down in signature...

Did you buy the version that has the 'stereo' IR sensors built into the lens? I've seen the MF 1.7 but not an AF version.

Also the Chinon AF system is not compatible with the Pentax Screw drive. Their lenses will fit but are MF only with the exception of the one I indicated above.

from the Chinon CP-9AF manual which is one of the more recent bodies.

There's fairly lagre chance that ebay seller is lying in lens description - I'll try to check it.

And the version with "stereo' IR sensors " seems to be fully compatible only with Chinon like CE-4s.
Thanks for remainding me of those, Peter Zack.
