My camera is changing lens aperture as I change ISO speeds or shutter speed it is set to manual mode.
My T6S doesn't. Do you see a little "M" in the top left of the settings screen? I am thinking the mode dial is off-by-two, and it is in Tv mode.
Thanks again,No, I dont see the little M, where is it supposed to be located?
See the shooting mode in the upper left?
Stop wondering and call Canon 1 (800) 652-2666. Something is wroing with the T8i.
