I just tried the above on the GH2 and then on the GH1 and cutting off all my preemptions I get 0.33s real world delay from half-press to actual acquisition on the GH2 and 0.39s real world actual delay on the GH1 (with the newest firmware). All over about 10 or 15 tries each. The closer I get to pressing the shutter at exactly as the hand was positioned the close it was to exactly those times - again self-eliminating any attempts are preemption.
So I guess the Gh1 and GH2 are the same. I assume human response (reaction time) is 0.1s as so many scientific studies claim. So subtracting the time my brain processed the signal to press and sent the message to my finger I guess the GH1 and GH2 both have a real-world lag-time of just a little over 0.2s.
I bet a DSLR would be about the same actually. Anyone with a DSLR got a stopwatch and wanna waste a few actuations finding out?
