Rolling shutter on Electronic vs First Curtain (lemmy.blahaj.zone)

I'm trying to understand why rolling shutter is a problem with electronic shutters, but not with electronic first curtain shutter modes. I've done lots of digging trying to get to the underlying reason for the difference, but I haven't had any luck, just various people talking about the fact it is a problem.

So fediverse photogs, who can help me with an answer?

Of course! Glad I could help!

Yeah, the sensor could still be in the reading phase and "collecting light" while the shutter is closed, but since the shutter's closed, there's no light getting to it so makes no difference, and therefore any "read delay" doesn't cause issues.
