Erwin Puts site list them, and all M lenses here: http://www.imx.nl/photosite/leica/overview/listm.html I understand the differences are hoods and filter size. At one time the 58mm fillter ring could be converted by Leica to the 60 mm filter ring. No longer available in the US, not sure about Solms. There are three different versions of hoods, the latest lens has the inbult hood. Hoods can be a problem, I am not sure if any are available from leica anymore. I think used and NOS are about it for replacement hoods. Optically, all 4 code numbers are identical. > > #2-- Alrighty now, this question isn't as rudimentary as how to load film in > M6 (a thread which incidentally got me to wondering if I hadn't been loading > my camera "properly" all this time)..... but it's close.

The filter ring is pretty close on the Noct, maybe why they changed it from 58 to 60, and the front element recessed quite a bit. Fitting a hood would be the next problem with the step up. Otherwise no problem that I know of. Hope this helps Dennis
