Leica M mount adapter for Pentax

Anybody seen an adapter to mount Leica M Mount lenses on a Pentax DSLR?

I've seen 1. It was Leica M to M42 as I recall. It did not have corrective glass so it would have only been useful for macro work.

Ricoh made a M module for the GXR. Is that close enough?

The M39 from Leica is commonly called LTM (Leica Thread Mount)

I just put a M39 screwmount answer on an old thread that kivis re opened.
Anyway the Leica M Bayonet register is only 27.95 mm compared to the K mount 45.46, so i think its impossible without optical adaptor.

The normal Leica M RF lenses would not work (due to the thinner Leica body as mentioned), but there were a number of lenses used with the Leica Visoflex system, which mounted a mirror / viewfinder box on the front of the Leica M. (Sounds strange today, but it was in use from 1936 (for LTM) well into the 70s.) These lenses mount far enough from the film plane to adapt to a Pentax, if there were an M to K adapter. I have a Viso and 200mm, but have mainly used their 65mm macro. It still works nicely, even on the M9 digital.

I wondered about the Visoflex. What is the registration distance?

Edit: Just found these adapters at cameraquest...perhaps the OP should consider Nikon or Canon?
