2) what you note may be the difference between an optical VF and an E-VF : with fast action, if you trigger the shutter when you view the peak of action in the VF, the peak is already gone in real life. You have to anticipate the peak of action and trigger the shutter a little earlier with an E-VF camera, but it should be exactly the same whether you are using AF or MF.--

You have any factual source for that time lag?
Just curious to know.
Olympus claims 29 ms for the E-M5 when using high refresh. See here under "Other Features", penultimate point.
That value is well in line with the value some of us have come up when trying to measure it. I haven't seen an official specification for normal refresh, but measurements in this case suggests the lag is roughly twice as long as with high refresh.
I have taken several action shots, vehicles, dancers, acrobats on trampoline, etc.. and never "felt" any lag at all.
Perhaps it has to do with the frame rate of the EVF mine is set to Normal and for me, it's quite enough.

Ahh so this must be a display processing lag as the math for the required minimum response time of the display itself is just as fast as the top of the line hdtv displays available now, 8ms and 4ms for 120hz and 240hz mode respectively.
