Contax lens on Pentax K mount

So is it possible to attach Contax mount lense to Pentax body? Are there any adapters? From what I found - the only way to do so is to perform some surgery on the lens or camera mount. But I also noticed that there are Contax to M42 adapters on ebay. Probably it's possible to attach it this way? (Contax lens -> M42 -> Pentax K)

You could possibly get an adaptor made, or use a couple of connectors, but any option would mean there would be an extension between the lens and the body which would mean that the lens wouldn't focus on infinity. Unless you buy a version with a glass element to correct the problem (an I don't think there is one for this combination)

Pete, thanks for the reply. Yes, I found some info on adaptors for Contax lens, but those where too expensive for me (50+ euros).

As for multiple adaptors - that's what I'm afraid of, and that's why I posted this topic. But I'm not 100% sure about this anyway, because M42 adaptor's thread is kind of inside the body when mounted on K mount, so I thought maybe it will work fine (with focus to infinity) without any glass elements. I hope someone tried such approach.

Yes that's fine and any other bayonet to screw mount adaptor that fits flush to the body are ok. But bayonet to bayonet are usually similar size so have to be adapted via an extension tube (with glass for infinity focus)
