Camera settings

After clicking the camera in the scene collection you get this tab where you can adjust various camera settings like you would do with a real camera. The focal length controls how zoomed in or out the final render will be. And the aperture controls the depth of field in your final render. Wider aperture leads to a shallower (blurrier) DOF and a narrower aperture leads to a sharper scene where everything is in focus.
