The M5 arm sits a lot further forward than the M8 shutter.
It's really quite simple. Measure the distance from the flange to the
shutter on the body, and then measure the distance from the flange to
the back of the collapsed lens on the lens. If the former is larger
than the latter, you're home free. Leave a mm or two leeway, for
peace of mind and/or flapping shutter blades :-).
A quick application of that theory showed that the current 50/2.8
Elmar is about 4mm shy of hitting the shutter blades, so plenty of
leeway.
