1. Introduction
The Haoge LH-RX1B Square Metal Bayonet Lens Hood is designed to enhance your photography by effectively shading the lens from stray light, which helps to prevent or limit lens flare. This results in improved contrast and overall image quality. Additionally, the robust metal construction provides crucial physical protection for your camera lens against accidental impacts and scratches. This manual will guide you through the installation, usage, and maintenance of your new lens hood.

2. Setup & Installation
Follow these steps to properly install the Haoge LH-RX1B lens hood on your compatible Sony Carl Zeiss Sonnar T* FE lens.
- Prepare the Lens: Ensure your camera and lens are powered off. If an original lens cap or filter is attached, carefully remove it.
- Attach UV Filter (Optional): The Haoge LH-RX1B lens hood is designed to allow the installation of a 49mm UV filter (not included) before attaching the hood. Gently screw the UV filter onto the lens threads until secure.
- Mount the Lens Hood: Align the bayonet mount of the lens hood with the corresponding grooves on your lens. Gently push the hood onto the lens and rotate it clockwise until it clicks into place and is securely fastened. For optimal performance, ensure the hood is horizontal and properly aligned.
- Attach Metal Cap: Once the lens hood is installed, you can attach the included metal front lens cap by pressing it firmly onto the front opening of the hood. The cap features a soft inner lining for lens protection.

3. Usage
The primary function of the Haoge LH-RX1B lens hood is to optimize your photographic results and protect your valuable equipment.
- Flare Reduction: The square design and internal special matte coating of the hood are engineered to block stray light from entering the lens, significantly reducing lens flare and ghosting. This improves image contrast and color saturation, especially when shooting towards bright light sources.
- Physical Protection: The lightweight aluminum alloy material provides a robust barrier against accidental bumps, drops, and scratches, safeguarding the front element of your lens. It also offers protection from rain, snow, and dust in adverse weather conditions.
- Enhanced Aesthetics: The precision-machined, surface-anodized finish complements the design of your camera and lens, adding a professional and stylish appearance.

4. Maintenance
To ensure the longevity and optimal performance of your Haoge LH-RX1B lens hood, follow these maintenance guidelines:
- Cleaning: Use a soft, lint-free cloth to wipe the exterior of the lens hood. For stubborn smudges, a slightly damp cloth can be used, followed by immediate drying. Avoid abrasive cleaners or solvents that could damage the anodized finish or internal matte coating.
- Storage: When not in use, store the lens hood in a clean, dry environment. The included metal cap can be used to protect the lens when the hood is attached.
- Inspection: Periodically check the bayonet mount for any signs of wear or damage. Ensure it remains securely attached to the lens.
5. Troubleshooting
If you encounter any issues with your lens hood, refer to the following common solutions:
- Hood Not Horizontal/Loose: If the lens hood does not sit horizontally or feels loose after installation, ensure it is fully rotated until it clicks into place. Sometimes, a firm rotation is needed to secure the bayonet mount. Remove and re-attach, ensuring proper alignment of the grooves.
- Difficulty Attaching/Removing: Check for any debris or obstructions on the lens's bayonet mount or the hood's mounting mechanism. Ensure you are aligning the marks correctly before twisting. Do not force the hood if it resists.
- Increased Flare: While designed to reduce flare, extreme lighting conditions can still cause it. Ensure the hood is correctly oriented and fully extended (if applicable). Adjust your shooting angle relative to the light source if flare persists.
