Leica & Pentax & Nikon

We are pleased to introduce the original Leitax adaptations. This website page is dedicated to replacement mounts for Leica-R lenses to fit Pentax cameras. If you have cameras or lenses from other manufacturers, please use the links above and to the left.

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 with a new lens mount designed to use the Leica-R lenses on your camera.

We are a manufacturer located near Barcelona, in Catalonia, Spain. This project started in my company, when we used a Pentax mount to adapt my camera to a binocular magnifier. I have been a Pentax user for 40 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 recently, only Canon and Olympus users could shoot with Leica-R lenses by means of cheap poor quality adapter. Many of these adapters present problems, cheaper manufacturing, methods of fit which loosen over a period of time while many have uneven plating thickness and fail to achieve a solid locking alignment.

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 manufactured for several decades in different countries, we found discrepancies at the point they focus to infinity, therefore we manufacture our bayonets to make sure all Leica-R lenses will focus on infinity.

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 instructions list on the left side.

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.

- Here is the sales list for Pentax-K mounts, for the other brands, please go to their own pages.

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

1--- The normal variant with Full and Half stops at the aperture ring, is 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 while still knowing the value of the aperture ring, just by 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.

- The registered mail service is reliable but the delivery time is not very fast or even regular. If you need the Leitax mounts fast or you have a deadline I'd recommend the courier option.

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.
