The a7III latency is a lot less with the EFCS, since the camera doesn’t have to wind the shutter before it can get the shot off. Sony have already explained that RAW is still compressed and hasn’t gained in bit depth. So, unless you are shooting with fast primes like f/1.4 at high shutter speeds, I would always leave EFCS on to avoid any vibration issues. Dec 12, 2016 at 08:24 AM Lamp to full, shutter to 1/1000 second, make 16 exposures with new focusing for each, turn the light down a stop, turn the shutter speed down a stop, make 16 exposures… until you get to 1/60 of a second. https://phillipreeve.net/blog/limitations-of-the-electronic-shutter-function/, https://www.fredmiranda.com/forum/topic/1453361, https://www.dpreview.com/forums/post/56328210.
