EOS 5D Mark IV Help with aperture settings

[alexandrabrown]

Hi! I have a Canon 5D Mark IV. I’m trying to figure out how to adjust the aperture while looking through the viewfinder. I’m able to adjust the ISO and shutter speed but not the aperture. When I click the Q button I can change shutter speed, ISO & aperture. Somebody please help. What am I missing??

In AV mode:

In manual mode:

Use the large dial on the rear of the camera (the one with the SET button in its middle).  That will allow you to adjust the aperture.

kvbarkley's answer is better.  I was only thinking about Manual mode.
