Hi, Two basic questions:
(1) The prime lenses have a unique code, as do the Tri-Elmars. The 6-bit coding has been stated as being necessary to adjust for the color fringing, etc. My question is, how does the M8/8.2 camera know to change the coding algorithm for the Tri-Elmar lenses (16-18-21 and 28-35-50) when the focal length has been changed, because (to my basic understanding), all that changes is the frame line in the viewfinder. Does anything else change by changing the focal length? I thought the focal length has to be exact in the computer of the camera so that the proper adjustment can be made.
(2) I don't know enough about how the 6-bit coding system works, but I keep wondering why Leica doesn't use a system whereby you just punch in the focal length and the max aperture (just as Nikon does with the manual lenses on D2xx< cameras). Why do they make it so difficult (with uncoded lenses requiring a trip to Leica facilities) when they could just have some firmware to handle ANY lens that could be mounted on the M8.
