NiSi NC UV Filter for FUJI X100 Series - Slim Lens Protector

In this review the NiSi NC UV Filter for the Fujifilm X100 series is evaluated as a practical, unobtrusive lens protector for photographers who use the fixed 49mm mount on X100 cameras. The biggest reason to buy is straightforward: it combines effective ultraviolet light blocking with physical protection in a frame that matches the X100 aesthetic and fits with the X100V and X100VI lens cap. For users who want simple, reliable protection and a neutral effect on image quality, this filter is a clear, low-risk addition to a Fuji X100 kit.

Key Features

• Compatibility: Designed specifically for Fujifilm X100, X100S, X100F, X100T, X100V and X100VI bodies, it fits the camera's fixed lens mount and works with the X100V and X100VI lens cap.
• UV Protection: Blocks ultraviolet light below 365nm while maintaining high light transmittance, helping preserve image clarity and color neutrality in bright outdoor conditions.
• Physical Shield: Acts as a durable lens protector against scratches, dust and moisture so the front element stays safer during travel and outdoor shoots.
• Advanced Coating: Proprietary waterproof nano coating reduces reflections and adds scratch and dust resistance for longer-lasting optical performance.
• Easy Installation: Installs by removing the standard mounting ring and threading the filter on, offering a secure fit without tools for quick setup.
• Design Match: The black frame is finished to match the X100 series aesthetic, providing a seamless look with minimal visual distraction.

Who It's For

The NiSi NC UV Filter is best for Fujifilm X100 series owners who frequently shoot outdoors or travel and want a low-profile way to protect the lens from physical damage while maintaining image clarity. Its simple screw-on installation and compatibility with the X100V and X100VI lens cap make it well suited to street, travel and everyday photographers who prefer to leave a protector on the lens full time.

Photographers seeking specialty optical effects, variable ND control, or filters for lenses other than the fixed X100 mount should look elsewhere, since this product is a dedicated UV protector tailored to the X100 family rather than a multi-purpose creative filter.

Pros & Cons

Pros

• Good fit with X100 series and compatible lens caps, preserving camera ergonomics and look.

• Durable waterproof nano coating reduces reflections and helps resist scratches, dust and moisture.
• Easy, tool-free installation by threading onto the lens mounting ring.

Cons

• Not a creative or variable filter, so it only provides protection and UV blocking rather than exposure control.
