There is no aperture ring on the lens. You set aperture with the camera body.
You can do that in either Manual (M) mode, or in Aperture Priority (AV) mode on the dial. I suggest you start wih AV Mode, because there the camera will set you a correct shutter speed for good exposure to fit your selected aperture value.

Why do so many people say "FER-tographer"? Do they take "fertographs"?
