XT2 overexposing at wide apertures

[nephrolepis]

I've had a second hand XT2 for a few months now but recently I've had an issue where whenever I open my aperture up the photos come out horribly overexposed.

I can take a photo at ISO 100, 1/4000 shutter speed and F2.0 in a relatively low light situation, with the light meter and histogram saying it’s underexposed and the screen and EVF being dark dark, but when I take the photo it comes out flooded with light. This only happens when the settings are set to wide apertures, so if I narrow it to f/16 and adjust the other settings it comes out normal but obviously this is very limiting when shooting. Everything seems normal when exposing for the photo but the second I take the photo way more light is let in than should’ve been, and it gets less severe the narrower the aperture. Could I have accidentally changed a setting causing this or is it likely an issue with the body or lens?

Are you sure it isn‘t just the display? Did you download and check the photos?
