Operating the Lens

Focal Length Adjustment (Zoom)

Rotate the zoom ring on the lens barrel to adjust the focal length between 12mm (wide-angle) and 40mm (telephoto). This provides a versatile 35mm equivalent range of 24-80mm, suitable for various photographic situations from landscapes to portraits.

Aperture Control

This lens features a constant maximum aperture of f2.8 across the entire zoom range. This allows for consistent low-light performance and shallow depth of field effects, regardless of the selected focal length. Aperture can be controlled via your camera body settings.

Manual Focus Clutch Mechanism

The lens is equipped with a manual focus clutch mechanism. To switch to manual focus mode, pull the focus ring on the lens barrel towards the camera body. This will reveal a distance scale, allowing for precise manual focusing. Push the ring back to engage autofocus.

L-Fn (Lens Function) Button

The L-Fn button located on the lens barrel can be customized via your Olympus camera's menu to perform various functions, offering quick access to frequently used settings without taking your eye from the viewfinder or screen. Refer to your camera's manual for specific customization options.

Maintenance

Cleaning the Lens

• Use a blower brush to remove dust and loose particles from the lens surface.
• For smudges or fingerprints, use a clean, soft microfiber cloth specifically designed for optics, along with a lens cleaning solution. Apply the solution to the cloth, not directly to the lens.
• Clean the lens body with a soft, dry cloth.

Storage

• Always attach the front and rear lens caps when the lens is not in use.
• Store the lens in a cool, dry place, away from direct sunlight and extreme temperatures.
• If storing for extended periods, consider using the included lens pouch for added protection.

Weather Sealing

This lens features a drip-proof, dust-proof, and freeze-proof construction. While designed to withstand challenging conditions, it is recommended to wipe off any moisture or dust promptly after exposure to maintain its longevity and performance.

Troubleshooting

If you encounter any issues with your lens, please refer to the following common solutions:

• Lens not recognized by camera: Ensure the lens is securely attached to the camera body and that the camera is powered on. Check for any debris on the lens or camera contacts.
• Autofocus not working: Verify that the lens is not in manual focus mode (check the manual focus clutch). Ensure your camera's autofocus settings are correctly configured.
• Image quality issues (e.g., blurry images): Check if the lens is clean. Ensure proper focus and appropriate shutter speed for the lighting conditions. If using manual focus, ensure accurate focusing.
• Lens not zooming smoothly: Inspect the zoom ring for any obstructions. If the issue persists, contact customer support.

For more complex issues, please consult the official Olympus support resources or contact their customer service.
