Gain in Dynamic Range with Expandable Iso?

Is there a gain in Dynamic Range say in a Canon 5d4, from 100 to 50?

[table][tr][td]ISO range (expanded)[/td]
[td]100 - 32000 (expandable 50-102400)[/td]
[/tr]
[/table]

It overexposes from base ISO to get ISO50 and corrects in post processing so will lose dynamic range and be more likely to clip whites.

No there is not. As Chris accurately pointed out, it is an artificial ISO that is really no different from shooting at ISO 100 and adding a stop of overexposure.

Is it the same with Nikon?

Anything too good to be true, is...

THXS! 

This is the best dynamic range comparison tool out there and it's real dynamic range not a theoretical calculation.  In the link I have the D810 (top line) and 5D4 (bottom line and you can see that the dynamic range flat lines when you go below base ISO which is 64 for the D810 and 100 for the 5D4:

To change cameras just tap on the right on the camera you want to turn on or off.

E.J. what is the base ISO of the Sony a7R2 ?

100

Base ISO is usually the lowest you can go without having to enable the extended/expanded ISOs

Great resource E.J. thanks! The 36Mp Sony sensor still amazes me.

And it's why after all this time, the D810 is still the best overall DSLR on the market.
