GeRRiT LH554-01 Lens Hood Instruction Manual

1. Introduction

Thank you for choosing the GeRRiT LH554-01 Lens Hood. This accessory is designed to enhance your photography by reducing lens flare and ghosting caused by stray light entering the lens. It also provides an additional layer of physical protection for the front element of your lens against accidental impacts and scratches.

This manual provides detailed instructions for the proper installation, usage, and maintenance of your new lens hood. Please read it carefully before use to ensure optimal performance and longevity of the product.

2. Product Overview

The GeRRiT LH554-01 is a dedicated lens hood specifically designed for the Sigma 23mm f/1.4 DC DN lens. Its petal shape is engineered to block unwanted light from various angles without causing vignetting (darkening of the corners of the image).

4. Installation

Follow these steps to correctly attach the lens hood to your Sigma 23mm f/1.4 DC DN lens:

1. Ensure your lens is clean and free of dust or debris.
2. Align the mounting marks on the lens hood with the corresponding marks on your lens. The lens hood typically has an 'IN' mark indicating the direction for attachment.
3. Gently push the lens hood onto the lens and rotate it clockwise until it clicks into place. Ensure it is securely fastened and does not wobble.
4. Verify that the petal shape of the hood is correctly oriented (the longer petals should be at the top and bottom when the camera is held horizontally).

Note: The lens hood can also be mounted in reverse for compact storage. To do this, align the 'OUT' mark on the hood with the lens's mounting mark and rotate counter-clockwise until it locks. This position is for storage only and will not provide flare protection.

5. Operating

Once installed, the lens hood operates passively to improve image quality. It is designed to block stray light from entering the lens, which can cause lens flare and reduce contrast. Keep the lens hood attached during shooting, especially in bright conditions or when light sources are near the edge of the frame.

When not in use, or for transport, the lens hood can be reversed and attached to the lens for a more compact setup. Refer to the 'Installation' section for instructions on reverse mounting.

6. Care and Maintenance

• Cleaning: Use a soft, dry cloth to wipe the lens hood. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Avoid harsh chemicals or abrasive materials, as these can damage the finish.
• Storage: Store the lens hood in a cool, dry place away from direct sunlight and extreme temperatures. When not attached to the lens, keep it in a protective bag to prevent scratches.
• Handling: Avoid dropping the lens hood or subjecting it to strong impacts, as this can cause cracks or deformities.

7. Troubleshooting

• Hood does not fit: Ensure you have the correct model (LH554-01) for your Sigma 23mm f/1.4 DC DN lens. Double-check the lens model number on your lens.
• Hood is loose: Make sure the hood is fully rotated and locked into place. If it still feels loose, inspect the mounting mechanism on both the hood and the lens for any damage or debris.
• Vignetting (dark corners in photos): This lens hood is designed specifically for the Sigma 23mm f/1.4 DC DN lens to prevent vignetting. If you experience vignetting, ensure the hood is correctly installed and not obstructed. If the issue persists, verify the hood's compatibility.
