I found this list today while researching various lens flange focal distances. It's a FAR more complete list than the Wikipedia article (about twice as many lens mounts) and even has some like Topcon RE and Pentax 6X7.

http://www.graphics.cornell.edu/~westin/misc/mounts-by-register.html

If you're wondering if a lens can be easily mounted on or converted to your camera, this list can help inform how easy or hard that will be.

That's a good up to date list, there's Micro 4/3 and Sony E on the list. Very useful.

Some errors:

M42x1(Pentax, Praktica, Zenit etc) and Pentax K have 45.5mm register

See:




M39 leica screw mount is only M39x1mm, never 26tpi.

These common errors caused by measuring metric sizes with the inch scaled measuring tool.

M39x1 Zenit mount have register 45.2mm

I can't speak to the Leice mount, but the M42 and K mount are 45.46mm, not 45.5mm. That's straight outta the Pentax technical manuals.

But the 0.04mm flange focal distance difference between "soviet" and "japanese" cameras explained at least in the Vivitar 28-85/2.8-3.8 lens service manual:



And in the Pentax ME service manual about the flange focal distance written:




So this is just a different measurement methods

Than:

Pentax M42 - from 45.47 to 45.53mm
Fujica M42 - from 45.47 to 45.51mm
Zenit M42 - from 45.48 to 45.52mm
Carl Zeiss Jena M42 - from 45.47 to 45.53mm

Got it. Yes, then, that makes sense.
