[Leica] Combined use of Power Supply and Remote Control of DM-R

[rdcb37 at dodo.com.au (Rick Dykstra)]

Nice work Fred.  And good on you for writing it up here where someone  
might find it if doing a search.

I took on a little project of this kind last year, making up an infra  
red trigger and remote control for my R8 system.  It's fun when it  
works as you planned.

Like you I use the mirror pre-release system to minimise vibration,  
but at the extreme telephoto end of things, rather than extreme macro  
photography.  It's a great feature of the R8/9.

Good luck with your 'invention'.  :-)
