I forgot who asked me this question but wanted to know if you could change the mount and coding like i did with the 135 apo. Here is your answer from Robert Fisk Leica NJ.
I spoke with the technicians today and due to the fact that they have not seen one of these lenses in a few years they are not sure if the coding can be completed. If you could please ask the customer to forward the lens into the service department with a description of what he/she would like to have performed. I believe that this modification can be completed but they want to see the lens first before giving a definite answer. Sorry for not having a better answer on this one.
