                        We sell replacement mounts to use Leica-R lenses on Sigma cameras.


Welcome to Leitax, this is our Leica-Sigma page. I would like to thank all the Sigma users that requested this mount and were waiting patiently for it. Finally, we can offer this new replacement Leitax bayonet to use one cam, two cams, three cams, R-cam  and ROM Leica-R lenses on Sigma bodies.

-This conversion is fully reversible and will not damage either the lens or the camera. But remember to check if your Leica-R lens will hit the protective glass of your camera at infinity. How to check it.

-After each complete power-down of the body (e.g. battery change), a Sigma lens has to be mounted once. After that, focus confirmation works fine with Leica lenses,  as long as the camera computer isn't powered down again.

-The Leica-R lenses will focus to infinity and will maintain the aperture click stops. 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.

- For metering in A mode with a SIGMA camera the aperture has to be turned to f1.0 Otherwise all images will be heavily overexposed. 

Some of the instructions you see on the left are for the Leica-Pentax bayonet. Just change the final step, installing the Leica for Sigma bayonet instead and you are ready to shoot with your Sigma camera.

A few Leica-R lenses will not clear the protection glass of the Sigma camera :

Super Angulon    21mm f:3.4
Summilux             35mm f:1.4
Fisheye-Elmarit  16mm f:2.8
Elmarit                 24mm f:2.8
Elmarit                 19mm f:2.8 ROM






Leica on Sigma , no adapter

In general, the Leica lenses with a focal distance less than 80mm will possibly hit the protection glass in the Sigma cameras.

But most of them can be used if shaving a bit the rear of the lens barrel,
I will make a list of fixable lenses in the near future.

Take here a look to one simple way to check your Leica lens mirror clearance.

As far as I know , all the rest of Leica-R lenses will not have problems with the mirror clearance issue.
Elmarit 100 on Sigma SD14 , no adapter

CAUTION!  The Leica Zoom lenses with ROM contacts are, in general, not suitable for Sigma 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.

Now you can order the Leica-Sigma bayonet here.

Please check how many screws has the Leica original bayonet of your lens to order the appropriate replacement.

Our Leitax bayonet for Sigma has one less hole than the original Leica lens, this way is more convenient to mount the lens on the camera, as the sixth hole will interfere with the camera's locking pin.  


Sigma bayonet, no adapter   
This is the standard Sigma bayonet with five holes for Leica-R lenses with six holes.  

Also included a spare bearing ball just in case the one at the lens get lost.

68 Euro
Ten holes bayonet, no adapter If the Leica lens use a ten holes bayonet, then you'd need a nine holes Leica-Sigma one.
It  has the standard five holes plus four additional.
Spare ball bearing included.

75 Euro

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  lenses.
3 Euro

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.

5 Euro

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.

5 Euro
This silicone grease tube is enough for dozens of bayonet replacements.
