Thee ONE things that nobody talking about EFCS seems to adress is how it works EXACTLY. If you, like in this video, assume that ok, we start taking the picture with the sensor fully exposed and then yes, the mechanical shutter moves in to block the sensor then there is a difference in amount of light that the bottom and top parts of the sensor receive. It could ONLY work if the speed at which is mechanical shutter moves in is extremely closely correlated to when the lines of the sensor are being read. Let's compare the sensor and the light with a sheet of regular A4/Letter paper that we lie flat on the ground outside. Now imagine it's drizzling a bit, the paper is slowly getting wetter. Now I want get an indication of how much drizzle in total falls on the paper in say 10 seconds. I start measuring (=looking at wetness of paper) at t=0.0 seconds, at the same time I slowly move a big piece of cardboard (same size or bigger than the paper) from the top of the paper further and further down until after 10.0 seconds the cardboard is exactly covering the paper below it. CLEARLY the BOTTOM of the paper that has been exposed the longest to the drizzle will be wetter than the TOP of the paper that right after I started got covered first by the cardboard. In fact the distribution of drizzle will be a linear function of the distance to the bottom. The very same is true for the sensor in EFCS. It's all nice to hear the mechanical curtain moves in but that part of the sensor that gets covered LAST by it will have received MORE light. I have yet to see a satisfactory explanation in full detail of how EFCS works.
In the case of Sony......particularly the a7 IV, the spec sheet for this camera shows; Mechanical and "Electronic Rolling Shutter". Is this ERS Sony's terminology for simply an Electronic Shutter? This is what frustrates me about Sony. They seem to use their own proprietary terminology for most all settings and features. It's like a foreign language that no one understands except Sony!!! Their User Guide might as well be written in Mandarin because, frankly, I have no idea what the hell they are referring to half the time!
Global shutter is a form of electronic shutter. Instead of reading line by line though, the sensor reads every pixel at once so the photo is perfectly stationary similar to how a mechanical shutter takes photos. It's basically the best kind of shutter there is, allowing for the ultra-fast shutter speeds of electronic shutter without the usual downside of fast moving objects being distorted like a baseball bat swinging.
Nice video! However, it raises a question for me: how do mirrorless lenses work?
light goes in the sensor directly

very informative.god bless you brother!!!!!!!!
Glad it was helpful!
why it is called electronic first curtain shutter when it is physical in nature? and which cameras have this electronic first curtain shutter?
Canon R8

Nice video. Not mentioned is the leaf shutter.
Kindly explain the global shutter

I will stay on my mechanical shutter. it is for my best shutter
Where’s the focal horizontal shutter? And where’s le circular leaf shutter?
Thanks for the feedback!
