Welcome to Leitax, a site dedicated to make our cameras even more enjoyable. My name is David Llado and I would like to present you a new lens mount designed to use the Leica-R lenses on your camera.

This project started when, at our company, which is located near Barcelona, in Catalonia, Spain, we used a Pentax mount to adapt my camera to a binocular magnifier. I have been a Pentax user for 30 years ( K2, still with me ), and this idea came to my mind, if we could use this mount to adapt more lenses on my Pentax bodies.

After some research, the best candidates were the legacy Leica R-mount lenses, needless to mention the quality of those lenses, and they can be obtained easily from ebay and other sites, also Leica owners would like to use their beloved lenses on modern SLR or DSLR bodies.

Until now, only Canon and Olympus users can shoot with Leica lenses by means of an adapter. These adapters are more convenient than disassemble lenses and change bayonets, but some have problems. Mostly the cheaper ones have uneven plating thickness and fail getting a solid adjustment, and the most important, those are not for Pentax, Nikon or Sigma cameras.

With a Pentax camera and this new bayonet, you get:

-A Leica lens solid on your camera as any Pentax lens.
-Your camera will meter in Av and M mode.
-Focus confirmation in the viewfinder.
-Image stabilization in the newest Pentax bodies.
-Diaphragm ring detents that will "click" like the original bayonet.

I have the K20D, but I think the settings are similar on other models: in the Custom Setting menu, go to "Using aperture ring" and set "permitted". This way, your camera will work and meter in Av mode with adapted lenses.

Of course, the Leica lenses will focus to infinity on Pentax cameras. After checking many models produced for several decades in three countries, we found differences at the point they focus to infinity, so our bayonet is measured to focus to infinity with all of them.

Thus, maybe some units will reach even beyond infinity, in this case turning back the focusing ring just half millimeter is enough.

The conversion is fully reversible and will not damage the lens nor the camera. We have already tried all the Leica lenses in the list, as more models will be checked, we will add them to our instructions section.

CAUTION! The Leica Zoom lenses with ROM contacts are, in general, not suitable for Pentax conversion. Most of models would need a custom and expensive work. I would recommend to find a non ROM model in case you wish a Leica Zoom lens.
