shave
Unfortunately, the Summilux 50/1.4 internal measures can be slightly different than other models.
One of our customers already reported this, and we had the same problem with our unit.
The solution is to shave a little bit the bayonet part that touches the aperture lever with a small and round file.
The two units had also some holes in different position, so I could use only five bayonet screws.

About the extra shaving with the Summiluxes, I had feedback from a 
customer that found his one working perfectly and all the holes in the right position, so it is not a general problem.
camera



Install the Leica-Pentax or the Leica-Nikon bayonet, the red dot in front the scale center for Pentax, and slightly to the right for Nikon.



Five screws are more than enough to keep the lens solid on Pentax, Fuji and Nikon cameras with the Leitax bayonet.
