Dear Al,
When you use a flash, do you use it on the camera or off the camera (via pc cord or off shoe cord)?
At the time being I use my old SB22 on my M6 and I'm still learning to use it off camera. I prefer the result of off camera flash, but it's not really practical. I find it's a completely different way of working than when I use my 30d with 430EX.
I mean with dslr, I don't worry about focusing, I can hold the flash with my left hand while, with AF, focusing at the same time. With M6, it's quite different. I'm still trying to get use to using the distance scale on the lens barrel. So most of the time I find myself focusing with my left hand while leaving the flash dangling (I use a strap on the flash, so I can leave it dangling while I focus. Learned this from Sean Reid's site)
Thanks, Bob
