Zeiss Contax lenses for Canon cameras

We sell Leitax mounts to use Contax lenses on Canon cameras

Welcome to Leitax, this is our Zeiss-Contax for Canon EOS page. After several requests from our clients, we decided to design these mounts with the same features than our previous models.

Our clients asked me to solve the problems that the traditional adapters have. They asked for a rock-solid, screw-on mount solution, no matter the weight of the lens. Like all our conversions, this one is fully and easily reversible too.

I did another improvement over the normal adapters: ours is covering the shinny clear metal of the Contax mount with a flat black painted rim. No reflexions inside the camera means no flares.

Complains are mostly for the usual poor slot-spring solution to hold the Contax lenses against the adapter. This is not good because the tension of the mount is made by wedging a soft metal with a slot. The slot will deform but will not bounce back to shape. Over time the adapter will be loose fitting and the lens will tilt, specially heavier lenses.

The Leitax mount will be screwed on top of the Contax original mount. This way, even the heaviest Contax lenses will be as solid in your Canon camera as any Canon lens. The screw-to-the-lens solution is much more solid but only can be used on Contax lenses with screws at the base of the mount.

Our mount is made in one piece and the mechanical precision is not compromised.

The Contax-Canon wide mount will trigger the AF switch in 1D series bodies. In this case, The Canon 1D series need to install a chip on the Leitax bayonet to work at all. If you wish to use these cameras without a chip, let me know. I will make a special version for you.

The Contax-Canon narrow mount will not trigger the AF switch in 1D series bodies. This means that if we have a chip on the mount, it will not make any effect when using the 1D series bodies, no problem for the rest on Canon cameras.

There is a convenient flat surface in our mount to glue an electronic chip if desired. This chip will enable the focus confirmation light in the viewfinder.

Your Canon camera can meter and adjust the correct exposure in A and M modes with adapted Contax lenses.

The Contax lenses will focus to infinity and will maintain the aperture click stops.

Please scroll down for the sales list and for the instructions

There are several Contax lenses that, even having screws at the base of the mount, our mount cannot be used on them because the screw positions are not coincident.
