UV Ultra Low Reflection Filter K&F Concept Nano-X MRC 37 mm (37mm) K&F

The K&F Concept UV Ultra Low Reflection Filter Nano-X MRC 37 mm is a slim, screw-in optical filter designed to reduce ultraviolet light transmission and protect the front element of compatible lenses. Its multi-resistant coating (MRC) and ultra low reflection surface help minimize flare and ghosting, maintaining image clarity in bright, hazy or backlit conditions while offering mechanical protection against dust, moisture and scratches.

Advantages

The filter's Nano-X multi-resistant coating provides water-, oil- and dust-repellent properties that simplify cleaning and increase durability. The ultra low reflection surface reduces internal reflections between the filter and lens, which helps preserve contrast and color fidelity. Its 37 mm screw-in size and slim profile make it compatible with compact lenses and reduce the risk of vignetting on wide-angle optics. The filter also serves as a practical first line of physical protection for the lens glass.

Suitable for

• Outdoor landscape and travel photography in bright or hazy conditions
• Daily lens protection during transport and general shooting
• Backlit and high-contrast scenes where flare reduction is needed
• Compact camera setups and small-diameter lenses (37 mm thread)

Key specifications

• Filter type: UV (ultraviolet) with ultra low reflection surface
• Coating: Nano-X multi-resistant coating (MRC) for water, oil and dust repellence
• Mount: 37 mm screw-in thread
• Profile: Slim design to minimize vignetting on wide-angle lenses
• Function: Reduces UV haze and internal reflections; provides front element protection

How to use

Screw the filter gently onto the lens front thread until it is secure but not overtightened. Use the filter for general shooting in daylight, especially in bright, hazy or backlit situations where ultraviolet light or reflections may reduce image clarity. For cleaning, remove loose dust with a blower or soft brush, then wipe the coated surfaces with a microfiber cloth and suitable lens cleaning solution if needed. Avoid excessive force when attaching or removing the filter to protect the filter threads and the lens.

Usage recommendations

The filter is intended as a neutral UV and protective accessory; it does not affect exposure settings. Combine with appropriate lens hoods to further reduce flare and protect the filter surface. Store the filter in a protective case when not in use to preserve the coating and glass quality.
