Help me understand an exposure issue on the SL3...

I never noticed this happening before, so I'm wondering if I accidentally changed a setting somewhere.

If I setup my SL3  to have AFs on the joystick press, when I press the shutter my exposure automatically gets raised and the histogram changes from where I have everything dialed in to a new historgam showing a brighter exposure (everything shifts to the right).  If I set the joystick press to AFs and Exposure Lock together this doesn't happen. 

But why is the exposure changing from where I have it set to when I press the shutter if I don't set the joystick to lock the exposure in a situation where I am still looking at the exact same scene I metered for?  My scene isn't changing from where I framed it and set everything.

Could you please share more information:

- what is your exposure setting when that happens (including ISO)?

- are you shooting in MF mode?

- how much does the exposure change when you half-press the shutter?

- which PASM mode are you using?
