A7s exposure bump in slog2

[eoshddidi]

Hi all,

Not sure if this has been mentioned before. When shooting manual, after hitting record, the a7s slog2 exposure gets a bump by 1 stop. The exposure meter in the bottom of the screen/EVF will shift from 0 to +1. is that factory default? 

I have also tested, if shoot with cine 4, the exposure gets a bump of 2/3 stop. Cine2 gets a 1/3 bump and no pic profile will not have any shift. 

I sometime rely on the exposure meter to get an rough idea on exposure, and I am getting thrown off by these bumps. 

Anyone has that experience? 

My firmware is up to date.
