Re: Shutter video

Here are my humble suggestions.

FCC- First curtain closes

C-1 - cocking of the 1st curtain

C-2 - cocking of the 2nd curtain

FCO - first curain opens

SCC - second curtain closes

SCO - second curtain opens (should be one of these peaks, really doesn't matter which one).

I also aligned the graphs using 2 first peaks which seem unchanged for all shutter modes.

So the shutter lag in "release lag time short" mode is ~4ms shorter than regular one.

In the EFC mode first curtain moves ~2ms earlier that in fully mechanical mode.
