GH5 In V-log auto iso shows right exposure but iso 400 shows overexposure.

So in V-log the minimum iso can be 400. I had the f stop at maximum and iso at 400 and it showed over exposure. But when I put it into auto it showed the exposure is correct.
Why is it so, does it mean in auto iso it can go below iso 400??

There are three main components of photography that has a direct bearing on the amount of light that enters the camera.

Yes , and fstop was 16 and shutter angle at 180 degrees in both cases. At iso 400 it showed imaged is overexposed. At auto iso it said its not. I found it odd.

You should be using ND filters to bring your exposure down. Also, Micro 4/3 lenses become diffraction-limited past f/8.0 which reduces detail and softens the image, so just for this reason alone you should be using ND filters to keep your smallest aperture around f/8.0 or wider.
