M39 Lens on my K100D?

Hi, I'm new to this forum. Been trying to search the forum for a while for any information on using Leica Thread Mount Lens M39 onto my K100D.

Currently I have a Russian made Industra 50 3.5 which is in M39 mount, and I use a M39->M42 adapter, then M42->K Mount adapter. They seems to work well.

I just wondering any other people in this forum have any experience in mounting those old M39 lens on their Pentax camera, and mind sharing some experience with me.

The reason I'm interested in M39 mount is due to the fast prime available. I like manual focus lens, coz my brain will just work out which lens to use for what situation, where as a zoom lens cause my brain to stop thinking to much. Some of the fine M39 examples: Voitlander Nokton 35mm F1.7, Canon 50mm F1.2, Summilux 50mm F1, and so on.

These lenses are 39mm Leica screwmount. The thread is the same but the registration distance is much too short to be able to be adapted to a Pentax K mount camera. People will tell you that you can use Leica lens for macro with an adapter, but I doubt the results would be very good, as these lenses were not designed for shooting at close up range. Anyway, the Leica Summilux 50/1.4 is a very expensive lens (even used) and you could get a new Pentax FA 50/1.4 for much less money.
