This manual provides instructions for the Canon RF 24-50mm F4.5-6.3 IS STM lens. Before use, ensure your camera firmware is updated to the latest version to avoid limitations such as unavailable magnified view functionality. The lens features a retraction mechanism; it must be extended to the shooting position before use.
Nomenclature
Key components of the lens include:
- Focusing/Control ring: Used for manual focus or assigned functions (e.g., aperture, shutter speed).
- Zoom ring: Used to adjust focal length.
- Focus mode/control selector switch: Toggles between AF, MF, and Control ring functions.
- Image stabilizer switch: Turns the IS function ON or OFF.
- Lens mount index: Used for aligning the lens with the camera body.
Attaching and Detaching the Lens
Attaching: Align the lens mount index on the lens with the index on the camera body. Turn the lens clockwise until it clicks into place. Ensure the camera power is OFF during this process.
Detaching: Press the camera's lens release button and turn the lens counterclockwise until it stops, then detach.
Shooting Preparations
The lens is equipped with a retraction mechanism to shorten its length for storage. Shooting is not possible while the lens is retracted.
- To shoot: Rotate the zoom ring in the direction of the white arrow until you hear a click.
- To store: Rotate the zoom ring in the opposite direction, past the 24mm position, until the retraction position indicator aligns with the zoom indicator.
Focusing and Control Ring
The ring's function depends on the Focus mode/control selector switch:
- AF: Sets the ring to act as a focusing ring for autofocus.
- MF: Sets the ring to act as a focusing ring for manual focus.
- CONTROL: Sets the ring to act as a control ring (function assigned via camera menu).
Image Stabilizer
The Image Stabilizer (IS) helps reduce camera shake. Set the switch to ON for hand-held shooting, especially in low light or when using slower shutter speeds. Set to OFF when using a tripod to prevent potential malfunction.
Accessories
- Hood (EW-63C): Reduces unwanted light and protects the front element. Align the red mark on the hood with the red dot on the lens and turn to lock.
- Filters: The lens accepts 58mm filters. Only one filter should be attached at a time.

- Aperture: f/4.5-6.3 (Max), f/22-32 (Min)
- Filter Diameter: 58mm
