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.
Yours sincerely,
Frank.
