Subject: [Leica] Best flash for M8?

Keep in mind that the "shutter" on the M8 is only a dust barrier.  It is not 
a timed device that affects the image/exposure/etc.

Comments like ... synchronization time.... are meaningless in this context 
of the shutter...  Best described as electronic flash
synchronization time.... during the time the photons are being collected by 
the sensor ( gated open), the flash contact is ordered
and the flash goes off.  Totally electronic, no shutter issues.....no 
mechanical anything.

Second, the flash ( X flash for us old timers) must go off when the shutter 
is totally open.  Slit shutters give really weird
results ( think about it..... a slit shutter and a fast flash = a slit 
picture image properly exposed.  Kinda useless)  Without
knowing for sure, the shutter in the M8 should always be open, totally, for 
capture.  There is no need for a mechanical "connection"
to the flash synch.  It should be all electronic.

Therefore, flash should ( should is the operative word) be available to very 
high or very low "shutter speeds"....   It is a matter
of electronic timing and the ability to setup the TTL flash computations 
that might limit the top end.

New creativity: Flash photography with the M8
The modern metal-blade slotted shutter enables extremely fast flash  
synchronization times down to 1/250 second. The new M-TTL flash  
technology ensures natural flash illumination through the activation  
of a metering pre-flash. The auto slow sync. function now allows  
available light exposures without camera shake in aperture priority  
mode combined with a natural fill-in flash.
