This manual provides essential instructions for the Canon RF 24-105mm F4 L IS USM lens. Ensure your camera firmware is up to date before use. Always handle the lens with care, avoiding direct sunlight through the lens and extreme temperatures to prevent damage.
Nomenclature
The lens features several key controls:

Attaching and Detaching the Lens
To attach the lens:
- Align the lens mount index on the lens with the index on the camera.
- Turn the lens clockwise until it clicks into place.
To detach the lens:
- Press the camera's lens release button.

Important: Always turn the camera power off before attaching or detaching the lens. Use the dust cap when the lens is not attached to the camera.
Focusing and Zooming
Set the focus mode switch to AF for autofocus or MF for manual focus. When in MF, rotate the focusing ring to adjust focus. For zooming, rotate the zoom ring. It is recommended to finish zooming before focusing to ensure accuracy.
Fixing the Zoom Ring
The zoom ring can be locked to prevent the lens from extending during transport:
- Turn the zoom ring to the widest position (24mm).
- Slide the zoom ring lock lever in the direction of the arrow.
To release, slide the lever in the opposite direction.

The control ring can be assigned to various camera functions. The Image Stabilizer helps reduce blur in hand-held shots. Set the switch to ON to activate. It is recommended to set the switch to OFF when using a tripod.
Hood
The custom lens hood protects the front element and reduces unwanted light. Align the red attachment position mark on the hood with the red dot on the lens, then turn clockwise until it clicks. To detach, press the button on the side of the hood and turn counterclockwise.
