This is the Leica-R Telyt 350/4.8

The bayonet side.....
as you can see, it is a 3-cams lens.

Unscrew the bayonet and lift it together with the black shroud.

As you can see, the small ball can remain sticked to the bayonet.

With the new Leitax mount model, you can reuse the black tube to avoid flares, take a look here.

We have to remove the two clear slopped shaped cams.

These are the removed cams

Now, I use to put a bit of grease in the hole where the small ball goes.

Ball in place.

Now we can screw the Leitax bayonet, the red dot goes near to the scale center.

Ready, this excellent Leica lens can be used now on our film or digital reflex camera.
