I think I've made up my mind to replace my original M8 with an M9. I'd like to use my CV 15, ZM 21/2.8, 35 Summicrons (III, IV), and 75AA with it - this is my main motivator, to get rid of the crop. These are all uncoded. What should I do in terms of coding and adapters to get the most out of them with an M9? Is there anyone (DAG?) who will code the ZM 21 mount? Or is this lens destined to never do well on it and I should bite the bullet and replace it with a Leica? 21 and 35 are by far my favorite focal lengths.
