ODD BEHAVIOUR // DOF Scale differs depending on Sony Mirrorless Body

[ectobuilder]

I put my Zeiss Batis 25 F2 @ F22 onto the A7S, A7II and A7RII.

Then I set the lens to infinite.

The OLED DOF Scale on the Batis reads differently for each camera:

A7S = 4.4ft to Infinite
A7II = 6.1ft to Infinite
A7RII = 7.1ft to Infinite

How is this possible? Aren't all these bodies using the same flange distance? And therefore the hyperfocal distance should be the same for all?

Different sensors? All full frame, but probably slightly larger/smaller would be my guess.

I received an answer from Zeiss as to what is happening. I've posted a new thread here with the answer:
