As far as I know: no, sorry - but I might be wrong so don't worry. If I'm not mistaken at the moment its imposible to build such a thing - a K-mount is bigger than the 42mm screw mount.

Dear Rebecca, Assuming you are talking about an m42 screwmount body, there seems to be no ideal solution for what you're looking for. You can buy an adapter with optical elements that allow you to use K-mount lenses on a screw mount body, but the extra optics degrade image quality and I've heard they behave a bit like a tele adapter. The other option is to go for something without optics but then you lose infinity focus, which might be alright if you only want to do macro work. The problem is a physical one: the m42 mount is narrower than the K-mount yet they have the same registration distance. But if the screw mount has a shorter registration distance, e.g. a leica screw mount body, then it should be possible - though I'm not sure if they exist. Not sure where to buy the adapters if you are happy with optical degredation or loss of infinity focus. I think I've seen them before, probably in B&H.

Re: screw mount adaptor
Since the K-mount is bigger than the screw mount, the adapter extends the lens away from the film. This is done with extension tubes so magnify and focus on small objects. BUT this reduces the ability to focus on far objects. You might find that the lens will not focus at infinity very well especially at wide apertures.

screw mount adaptor
Hi, I have a quick question. I have been looking around to find a adaptor for this new screw mount camera I have so that I can use the bayonet type lens that I have with it. My question is.. is there such a thing? and if so .. what is it called? I can not seem to come up with anything other then the "use your old screw mount lens on your new bayonet mount camera". And I need it for the other way around. Thanks in advance for the help.
