What is the reason? For the simple person?

Electronic Shutter (ES) read out has higher read noise than Mechanical Shutter (MS).

I must be missing something. I thought ES was just MS without the M - so the mechanical bit just isn't there.

What am I missing? Is there something I can read that explains the actuall mechanisms of ES & MS?

Decent explanation by Fujifilm here:

Bottom line, as I understand it, there remain situations (most often relating to motion photography) where the differences between the two can become very apparent. It's my understanding that motion related artifacts attributable to ES still exist, even in the latest generation ES implementations. I'm more than happy to stand corrected if there is updated data that suggests otherwise with newer gen cameras. A reference to such information -- if it exists -- might be very helpful in answering the questions being raised here.

Meanwhile, out of an abundance of caution, and until I see data to the contrary, I will continue to avoid using ES in any situation where motion is involved.

The link is helpful. Keep in mind the noise difference is very minor compared to issues such as rolling shutter.

In another thread (regarding the X-T5), Bill clarified that EFCS is much closer to MS regarding noise than ES. Beyond that, rolling shutter is almost entirely eliminated with EFCS (the two factors are interconnected).

I think Fuji has done a very good job of integrating auto ES-EFCS-MS at the proper shutter speeds with the majority of shooting situations defaulting to EFCS - for good reason - it consistently yields the best image quality results unless you're using flash.
