Actually you enable electronic first curtain, to have fewer vibrations when you shoot.


There are several conditions under which EFCS causes the images to look worse (either all the time or as a function of shutter speed)

(1) certain lenses have worse bokeh with EFCS and shutter speeds faster than 1/2000
(2) bracketed shooting affected as well, and
(3) i think i recall something about IBIS can degraded as well

There have been a few threads on this that can be searched for if interested.
