I have a Canon EOS R50, a mirrorless camera, which also seems shutterless - If I take pictures of, for example, an airplane with a spinning propeller, will I still get that “strange rubber propeller” effect? 1) the camera may have a shutter and I just don’t recognize it or 2) the sensor is read in such a way as to produce the effect.
So with the 2nd type shutter, The sensor is exposed and then the shutter closes, the sensor is read in darkness so the image on it does not change. Then the shutter opens and I start seeing what the camera sees in the view-finder-eyepiece?
