Jeez! I guess you do not understand what causes a drop in DR and what does not!DPReview amongst others have noted that use of the EFC on the A7RII makes for noisier shadows. In my book, that means less effective DR. EFC also causes problems with fluorescent lights (not a problem for me) and can cause a rolling shutter effect too.
I believe those are all facts, and fairly straight ones.
In other words, EFC is not a 'free lunch'.
EFCS = Electronic First Curtain Shutter. No drop in DR or rolling shutter!
Electronic shutter aka "silent shutter" with no moving mechanic parts, there is a drop in DR and it also causes rolling shutter and problems with fluorescent light (banding).
