Perhaps some would be interested in the flange to film distances 
(register).

Although the distance is important, if the lens mount is narrower than the 
camera mount, it may be possible to sink the lens in a little.


I've adapted some info from http://www.a1.nl/phomepag/markerink/mounts.htm

Here is a list by distance, then one by camera/mount

"The moment one gives close attention to anything, 
even a blade of grass, it becomes a mysterious, 
awesome, indescribably magnificent world in itself --
