[Leica] Best flash for M8?

[lucien_vd at mac.com (lucien_vd@mac.com)]

Dear Frank,

The DMR + R8 or R9 use a similar sensor than the M8, and the same  
shutter.

The shutter was designed long before the DMR.

The DMR is working up to 1/8000th in manual mode.

Do you really think that the DMR is capable to order the R8/R9  
shutter to slow down to 1/250 when manually set on 1/8000 on the  
camera body ?

And how do you explain that on the DMR  you can use the HSS flash  
mode, which is a high speed flash mode between 1/350 and  1/8000 ?

AFAIK, the M8 and DMR sensors are both working with a slit shutter  
working steplessly up to 1/8000, as stated in all the Leica  
literature that you will find on the following web sites.
