Welcome to Leitax, this is our QBM-Canon EOS page. After several requests from our clients, we decided to design a QBM to Canon mount 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. Just like our Leica-Canon model.
Complains are mostly for the usual poor slot-spring solution to hold the Rollei or Voigtlander 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 Rollei or Voigtlander original mount. This way, even the heaviest lens will be as rigid on your Canon camera as any Canon lens. The mount is made in one piece and the mechanical precision is not compromised.
Our Leitax mount will trigger the AF switch in 1D series bodies.
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 lenses.
The Rollei and Voigtlander lenses will focus to infinity and will maintain the aperture click stops.
The Leitax mount for Canon fits perfectly on top of the original QBM bayonet, using the same original screws of the lens mount.
Please take a look at these instructions
- Caution! The Canon 1d series cameras 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.- Caution! This Leitax mount is only compatible with QBM lenses with three screws at the original mount.
You can order the QBM-Canon bayonet here.
- 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.

-The O-ring also forms tight friction, it will avoid losing the cap.
-It covers the entire bayonet diameter, providing more protection against blows and scratches.
I use this model for the Flat screws on the QBM 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.
