Q: 9. How do you manually focus this lens?

A: To manually focus when using the Canon RF 50mm f/1.8 STM Lens, you may set the Focus Mode in your camera to Manual Focus, then set the [CONTROL/FOCUS] switch built onto the lens to [FOCUS]. You may then rotate the control ring built onto the lens to adjust your focus. You can also press the [MAGNIFY] button (button of a magnifying glass) on the back of the camera to increase the magnification on the camera's LCD screen to assist your viewing during manual focus. If the camera is set to Autofocus and the [CONTROL/FOCUS] switch is set to [FOCUS], you should also have full-time manual focus override, allowing you to focus manually while the camera is still set to autofocus mode.
