EFC, yes, so no shutter shock. It's a hybrid:
"The GM1 also houses a new shutter mechanism. The shutter itself uses a
stepping motor rather than a spring-loaded
design, resulting in a significantly smaller unit. The camera's sensor
initiates image capture with an electronic first
curtain. Using a stepping motor limits maximum mechanical shutter speed to
1/500 sec - after that it's all electronic
shutter up to a maximum shutter speed of 1/16,000 sec (yes, that's three
zeros)."

A benefit of the stepper motor design is a maximum speed of 60 sec. I don't
think that's possible with a full eShutter,
as yet.

Probably the fastest speed at which the stepper motor mech. shutter completely
uncovers the sensor.
