I don't recall any discussion about this on this list over the last several years. The current coding system does more than provide a focal length and maximum aperture. For example there are several 24mm M lenses. Each has different coding and implicitly different correction applied. You also need the correct bayonet flange design to bring up the right framelines. Coding does not work without those. Zeiss has acknowledged this with their excellent M lens designs now too. Every new Leica lens made for the last several years has the coding. Not unreasonably Leica would like to sell some of those new lenses as well to help stay in business. Almost every other M lens ever made can still be used. That is remarkable. Do you have the M8? Which lenses are not working well for you? How about a petition to Nikon to put the aperture ring back on all of their lens designs? ;-) Another one to stop them encrypting their white balance data in NEFs to try to make their Raw format proprietary. DNGs would be good. Good enough for Leica and Hasselblad and Pentax. I'l sign that one when it gets going. 2009/1/21 Mitch Alland <mitcha@mac.com> > There has been extensive discussion of Leica's use of lens coding to > identity lenses to the M8.
