Canon 90D over exposed photos

[4huskers]

Just got my 90D yesterday and except early in the morning every shot is over exposed. I shoot in TV 1/800 ISO auto with a Sigma 150-600 Contemporary. Shots with my 80D using the same setting are fine. I've attached an example.

What was the ISO and aperture?

If a flash was active, it will change the shutter speed on you without asking. So pls report the shutter speed too from the EXIF.

The obvious thing to do is to shoot in M at appropriate settings, for instance 1/800 s, f/8 and ISO 100.

I've returned it. I found on another forum where several users reported the same problem when they paired a 90D with a Sigma lens. I'll just go back to my trusty 80D. Thanks for responding.
