DAG does this.... Leica? Sherry? Or, just buy a rear lens flange from China and code it yourself... it MAY be fine focusing wise.... it MAY need a re-collimation.... For about $20 you can't go too far wrong..... If you get the flange, there are 2 ( at least ) models... a 5 screw and a 6 screw version. Look at the rear of your lens to find the correct version..... and then for focal length... 50/75, 28/90, and 35/135. ( makes 6 variations right there...!) Code using Black and White nail polish..... Total cost out the door is about $25. And you get to keep the old flange! Collimation from DAG cost me $100 plus shipping. Going that way, cost is $125-175. I think Leica is at $300 or more right now.... Frank Filippone Red735i at verizon.net All they do is change the mount. It should only take a couple of weeks. My 21/2.8 was originally bought coded from the factory, but had the wrong mount,(it was an early coded lens), so it did not record the info. I sent it in for the correct mount and it was back in just under 2 weeks. Gene
