I know there are a couple of shooters on this forum who use Leicas and I have a question regarding flash. I find the 1/50th flash sync to be no real limitation for the times I use flash indoors as I'm usually dragging the shutter to get background light anyway. But outdoors it's a big problem. My workaround last year was to use an 8x ND filter and let the TTL flash pump out more light to compensate. But batteries die quickly doing that, of course. A bigger, more powerful flash dwarfs the camera and makes it unweildy. Do you have any other workarounds to the 1/50 sync outdoors?
