E-shutter in Canon EOS M5?

Re: E-shutter in Canon EOS M5?

I believe Canon uses an electronic first curtain. This means when taking the picture the exposure is started electronically and then the shutter is closed, ending the exposure. This means only 1 movement of the shutter at the end of the exposure. Many mirrorless cameras close the shutter, open it for exposure and then close it to end exposure. Thats 3 movements. The electronic first curtain results in less mechanical noise and also less chance of the shutter causing vibrations since it only moves at the end of the exposure.

I know in the m43 cameras I have, my EM5 has the 3 movements and my GM1 uses electronic first curtain. Big difference.
