Key Features

• Impact and Explosion-Proof Durability: Built with advanced materials to withstand significant impacts, protecting your lens from accidental damage.
• Nano Coating: Features multi-nano coatings for waterproof, scratch-resistant, and dustproof properties, ensuring easy cleaning and longevity.
• Enhanced Image Clarity: High-definition CINE optical glass with 99% light transmittance reduces flare, minimizes reflections, and reproduces neutral colors, ideal for high-megapixel cameras.
• Slim Brass Frame: An ultra-slim 3.5mm brass frame prevents vignetting, even on wide-angle lenses (e.g., 14mm). The textured twill surface provides an easy grip for installation and removal.
• Advanced UV Blocking: Effectively blocks ultraviolet light below 395nm, reducing atmospheric haze and preventing bluish casts in photos, especially in bright outdoor conditions.
• FX Filter Transformation: In the rare event of severe impact causing cracks, the filter is designed to remain intact, preventing glass fragments from damaging the lens and potentially creating unique creative effects.

Setup

1. Verifying Lens Compatibility

Before attaching the filter, ensure it is compatible with your camera lens. The filter size is indicated by the "ø" symbol followed by a number (e.g., ø49mm) on your lens barrel or inside the lens cap. This filter is specifically designed for lenses with a 49mm filter thread.

2. Attaching the Filter

1. Carefully align the filter's threads with the threads on the front of your camera lens.
2. Gently rotate the filter clockwise until it catches the threads.
3. Continue to turn clockwise until the filter is securely fastened. Avoid overtightening to prevent damage to the filter or lens threads.

The filter is equipped with front and back threads, allowing for easy stacking with other camera filters if desired.

Operating the Filter

The NiSi Armor FX PRO Nano L395 UV Filter functions as a continuous protection layer for your lens while simultaneously improving image quality.

• Lens Protection: The primary function is to protect the delicate front element of your lens from dust, scratches, impacts, and other environmental hazards.
• UV Light Reduction: By blocking UV light below 395nm, the filter helps to reduce atmospheric haze and bluish casts, especially noticeable in landscape photography or at high altitudes. This results in clearer, more vibrant images.
• Reduced Reflections: The low-reflection coating minimizes internal reflections and flare, contributing to sharper images with better contrast.

Maintenance

Proper care will extend the life and maintain the performance of your NiSi Armor FX PRO Nano L395 UV Filter.

• Cleaning: Due to its Nano Coating, the filter is waterproof and oil-proof. For cleaning, use a clean microfiber cloth specifically designed for optical surfaces. For stubborn smudges, a small amount of lens cleaning solution can be applied to the cloth (not directly to the filter).
• Storage: When not in use, store the filter in its protective case to prevent dust accumulation and accidental damage.
• Handling: Always handle the filter by its brass frame to avoid touching the glass surface and leaving fingerprints.

Troubleshooting

• Vignetting: If you observe dark corners in your images, especially with wide-angle lenses, ensure the filter is fully seated and that you are using the correct slim-frame version. The ultra-slim 3.5mm brass frame of this filter is designed to minimize vignetting.
• Reduced Image Quality: Ensure the filter is clean and free from smudges, dust, or moisture. While the filter is designed for high clarity, any obstruction on its surface can affect image quality.
• Filter Cracks: In the unlikely event that the filter glass cracks due to extreme impact, the laminated design prevents shattering into loose fragments. The filter can remain on the lens, protecting it from further damage. This "FX Filter Transformation" can also be used creatively for unique flare effects.
