I must be misunderstanding something here. I'm consistently reading an underexposure when I use aperture priority mode.
So here I'm in manual mode, f2.5, 1/20s and the camera says the exposure is fine.
And then if I set the camera to aperture priority mode with the same aperture of f2.5, it's opting for a 1/125s shutter speed and thus is showing as underexposed.
Even setting the exposure compensation doesn't change it from showing as underexposed. I've experienced the same problem in bright sunlight where I had to set the shutter speed to 1/750s to get an OK exposure on manual.
In response to the comments I'm including a picture of the exposure compensation setting when on aperture priority mode
Can anyone advise me what the problem might be? This is quite a different beast to my DSLR so I'm feeling a bit lost.
