This is the first and original Leitax website page, here we sell replacement mounts for Pentax cameras. If you have a camera from another manufacturer, please use the links above and on the left side.

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.

Super Prgram


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.

90 Elmarit on K20D


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.

Pentax K5


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.

My email address: info@leitax.com

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.

- You can see pictures taken with Leica-R lenses with modern digital cameras at the Leitax group at Flickr.

---- We are now offering three variants of the Leica-Pentax bayonet:

1--- The normal variant with Full and Half stops at the aperture ring, just like the original Leica-R lenses are.
2--- The special variant with only Full stops. With it, you can compose the picture in the viewfinder and take all the pictures you like changing the diaphragm value many times and still knowing the value of the aperture ring, just counting the "clicks".  You don't have to remove your eye from the viewfinder to check the diaphragm value.
As an additional benefit, you can use 1/3 diaphragm values.
3--- The special variant with no F-stops. This one is intended for the film makers, who need a silent aperture ring operation. Usually they remove the small ball to avoid the "clicks", but this is not good, there is a danger to destroy its spring and also this creates a new problem: the iris spring can move the aperture ring if there is nothing keeping it in place.

With certain models, we'll have to manipulate inside the lens, it's not a good place for something metallic. With this plastic tool I don't make any scratches in the Leica or Zeiss lenses.

I use this model for all the Phillips screws in the Leica and Zeiss lenses, it is industrial grade quality made by Irazola, and the design is very good, you can push and turn it firmly with the rotary end and the rubber finish.

This one is for the small black screws at the Leica's lens rear shroud. Unfortunately, Irazola doesn't produce a size for the bayonet flat screws founded in older Leica lenses.
