Setup
Before using your Sigma 24-35mm F2.0 Art DG HSM Lens, ensure it is properly attached to your Canon EF mount camera body.
- Attaching the Lens: Align the red or white index mark on the lens barrel with the corresponding mark on your camera's lens mount. Rotate the lens clockwise until it clicks into place.
- Removing the Lens: While pressing the lens release button on your camera body, rotate the lens counter-clockwise until it stops, then detach it.
- Attaching the Lens Hood: The lens comes with a petal-shaped lens hood. Align the hood with the front of the lens and twist it clockwise until it locks. The hood helps to prevent flare and protect the front element.

Operating the Lens
This section details the primary functions and controls of your Sigma 24-35mm F2.0 Art DG HSM Lens.
Autofocus (AF) / Manual Focus (MF) Switch
Locate the AF/MF switch on the side of the lens barrel. Slide the switch to 'AF' for autofocus operation or 'MF' for manual focus. In AF mode, the Hyper Sonic Motor (HSM) provides fast and quiet focusing. For precise adjustments, you can often override autofocus manually even when the switch is set to 'AF' (Full-time Manual Focus).
Zoom Ring
The wide, ribbed ring closer to the camera body is the zoom ring. Rotate this ring to adjust the focal length between 24mm and 35mm. The current focal length is indicated by the white line against the numerical scale.
Focus Ring
The narrower, ribbed ring closer to the front of the lens is the focus ring. In MF mode, rotate this ring to achieve sharp focus. The distance scale on the lens barrel indicates the current focus distance in feet and meters.
Aperture Control
The aperture (f-number) is controlled via your camera body. This lens features a constant maximum aperture of F2.0 across its entire zoom range, allowing for consistent exposure and depth of field control. The minimum aperture is F16.

Maintenance
Proper care and maintenance will ensure the longevity and optimal performance of your Sigma lens.
- Cleaning the Lens: Use a soft, lint-free cloth or a lens brush to remove dust from the lens surfaces. For smudges or fingerprints, use a specialized lens cleaning solution and a clean microfiber cloth. Avoid touching the glass elements directly with your fingers.
- Storage: When not in use, store the lens with both front and rear caps attached in a cool, dry place away from direct sunlight and extreme temperatures. Using a desiccant can help prevent mold growth in humid environments.
- Handling: Avoid dropping or subjecting the lens to strong impacts. Do not force any moving parts.

Troubleshooting
If you encounter issues with your lens, refer to the following common problems and solutions:
- Autofocus Not Working: Ensure the AF/MF switch on the lens is set to 'AF'. Check your camera's focus mode settings. Clean the electrical contacts on both the lens and camera body with a clean, dry cloth.
- Images Are Blurry: Verify that the lens is properly focused. Check your camera's shutter speed to ensure it's fast enough to prevent motion blur, especially in low light. Ensure the lens is clean and free from smudges.
- Lens Not Recognized by Camera: Remove the lens and reattach it, ensuring it clicks securely into place. Turn the camera off and on again. If the issue persists, consult your camera's instruction manual.
- Unusual Noises: If the lens makes unusual noises during operation, discontinue use and contact customer support.
