Subject: [Leica] M8 RAW--high ISO improvement!

When the light is good (i.e. ISO less than or equal to 640) then my M8 is 
the best camera I have ever owned. And so that is the camera I use much of 
the time around Alicance, a rather sunny place. But when the light is not so 
good, then my Fuji X-T1 is far superior, and so this is the camera I am 
taking to Brussels next week, to Geneva the week after that and to Paris 
that week after that?because those are business trips and so most of my 
photography will be after sunset.
