• Focus Mode Switch (AF/MF): Toggles between Autofocus and Manual Focus.
• Focus Limiter Switch: Restricts the focus range to improve AF speed. Options typically include FULL, 3m-∞, and 1.5m-3m.
• OS (Optical Stabilizer) Switch: Activates or deactivates the Optical Stabilizer. Different modes (1, 2) may be available for various shooting scenarios.
• Custom Switch (C1/C2/OFF): Allows selection of custom settings configured via the SIGMA USB DOCK (sold separately).
• Aperture Ring: Adjusts the lens aperture.
• Aperture Ring Click Switch: Enables or disables the click stops on the aperture ring for smooth, silent aperture changes during video recording.
• Lens Lock Switch: Locks the lens barrel to prevent accidental extension or retraction during transport.

Operating the Lens

Autofocus Operation

Set the Focus Mode Switch to AF. The lens will automatically focus when the camera's shutter button is half-pressed. For faster autofocus in specific situations, utilize the Focus Limiter Switch to restrict the focus range.

Manual Focus Operation

Set the Focus Mode Switch to MF. Rotate the focus ring on the lens to adjust focus manually. Use your camera's focus peaking or magnification features for precise manual focusing.

Optical Stabilizer (OS)

The Optical Stabilizer helps reduce camera shake, especially useful in low light or when shooting handheld. Set the OS Switch to 1 for general shooting or 2 for panning shots (if available). Turn OS OFF when using a tripod or when shutter speeds are fast enough to prevent blur.

Aperture Control

The lens features an aperture ring for direct control over the aperture. You can set the aperture to 'A' (Auto) to control it from the camera body, or manually adjust it using the ring. The Aperture Ring Click Switch allows you to enable or disable the click stops for smooth aperture transitions, which is beneficial for video recording.

Maintenance

Cleaning the Lens

• Use a blower brush to remove dust from the lens surfaces.
• For smudges or fingerprints, use a clean, soft microfiber cloth specifically designed for optics, along with a small amount of lens cleaning solution.
• Never use organic solvents like paint thinner or benzene to clean the lens.

Storage

• Store the lens in a cool, dry place away from direct sunlight and high humidity.
• Attach the front and rear lens caps when not in use to protect the glass elements.
• If storing for extended periods, consider using a desiccant to prevent mold growth.

Handling Precautions

• Avoid exposing the lens to extreme temperatures or sudden temperature changes.
• Do not drop or subject the lens to strong impacts.
• Keep the lens away from strong magnetic fields.

Troubleshooting

Lens Not Focusing

• Check if the Focus Limiter Switch is set appropriately for your subject distance. Try setting it to FULL.
• Verify that the lens is securely attached to the camera body.
• Clean the lens and camera contacts if necessary.

Optical Stabilizer Not Working

• Ensure the OS Switch is set to 1 or 2, not OFF.
• The OS may not be effective at very high shutter speeds or when mounted on a very stable tripod.

Image Quality Issues

• Check for dirt or smudges on the front and rear lens elements.
• Ensure the lens hood is properly attached to prevent flare.
