The registration part is the distance from the mount to the sensor. Rangefinders like Leicas and Contaxes ran about 28mm for registration. SLRs are/were all much longer. The 18mm registration of the Nex means that you can add an adapter to adapt the E-mount to some other mount type, and make up the difference between the 18mm registration of the Nex and whatever the lens was designed for. Since 18mm registration is less than that of pretty much any 35mm film ever made, it's possible to make adapters to connect all those lenses to the Nex.

Thanks for explaining this so clearly. I'd wondered why so many legacy lenses fit the NEX. Now I understand.
