I just got my Mark iii and took maybe 300 shots with it and my converted N lenses. Seems like the NAM-1/Mark iii combo has a hard time focusing- misses focus a lot and seems soft. My NAM-1 80f2 is really bad- I can't get a single focused shot, no matter how many different microadjustments I make. At some point I think I got the adjustment just right, but everything is just soft, no real sharp point in the picture At first I thought it was the NAM-1 or the lens, but my 85 1.4N that is always right on and sharp also is having issues on the Mark iii.

So to confirm it wasn't a faulty body, I tried my Canon L lenses on the Mark iii and they are stellar and accurate. Go figure. So the body seems to work fine with modern lenses.

Any ideas? I'm thinking maybe with the new 61 pt AF system, the Conurus mounts are not communicating correctly with the camera? My N lenses work really well with the Mark ii, and I'm going to test the NAM-1 more with an older camera as well.

Ok, I figured it out. The NAM-1 + 80 f2 requires a +30 microadjustment, and the N lenses require about +17-20.
