Peter, Hi, I've used several 135 Leica lenses over the years with the favorite being a late, (55mm filter size) "M" lens with the head removed and on a short focussing mount, then mounted on a 14167, M-to-R adapter which Ive used on my R's and with a custom "T-Mount adapter that I got several years ago in Germany, I can put it on my trusty Nikon F4 and have matrix metering AND matrix balanced flash control. Talk about the best of both worlds.
