[Leica] Collapsible lenses on the M8/9

[jbcollier at shaw.ca (John Collier)]

I double-checked with the technical chap(ette)s from Leica NJ and the late 
model 50/2.8 (1995 and on) can be used with impunity. With the exception of 
the recent 90/4 macro, which also can be used without trepidation, all other 
collapsible lenses should only be used fully extended and never collapsed 
while mounted on an M8/9.
