E-M5 II: Preview Lock (Aperture) & underexposed picture

Hi,

I've noticed today when testing my new Olympus 60/2.8 macro that when I take a picture with the Preview of aperture locked (front button with the setting to keep it activated until pressed again) the result is often underexposed (in A mode, speed is higher and/or auto ISO lower) compared to the same picture without Preview locked.

I try to reproduce it with my Olympus 12-40/2.8 but without much luck (maybe a little difference but not as much as the 60/2.8).

Have to try with some other lens and a tripod to be sure but I wonder if someone have noticed something similar, especially with the 60/2.8 lens.

Wonder if my lens is somewhat faulty, or if the Preview lock must not be used when taking picture ?

Nobody have seen this kind of behavior ?
As a beginner in macro, Preview lock is really useful for me.

Could someone with a E-M5 II and an Olympus 60/2.8 can try to take a few pictures with Preview lock and check if they are not underexposed, I would be really grateful.
