UV Filter K&F Concept Nano-C HMC UV - 72 mm glass optical filter for lens protection and UV reduction

The K&F Concept Nano-C HMC UV - 72 mm glass optical filter reduces ultraviolet light reaching the camera sensor while protecting the front element of compatible 72 mm threaded lenses. It combines a Nano-C surface treatment with HMC (Hard Multi-Coating) layers to maintain neutral color rendition and high light transmission. The filter mounts by screwing onto the lens thread and is intended for routine outdoor and travel photography where UV haze and physical lens protection are concerns.

Advantages

This 72 mm UV filter provides UV reduction to help improve image clarity and reduce atmospheric haze in daylight shooting without significantly affecting color balance. The Nano-C and HMC coatings enhance light transmission, repel water and resist minor scratches, and simplify cleaning. As a physical protective element, the glass surface shields the lens from dust, fingerprints and incidental impacts while remaining thin enough to avoid vignetting on most lenses designed for 72 mm filters.

Suitable for

• Outdoor daytime photography to reduce ultraviolet haze
• Protecting the front element of 72 mm thread lenses from dust and light impacts
• Landscape and travel photography where clear distant detail is important
• Everyday shooting when an extra layer of front protection is desirable

When it may not be suitable

This UV filter is not intended to replace specialized optical filters such as polarizers or neutral density filters; users seeking glare reduction, polarization control or exposure reduction should choose purpose-built filters. It is also not necessary for low-light, indoor, or artificial-light situations where UV reduction has little or no effect on image quality.

Key specifications

• Filter type: Optical UV filter
• Thread size: 72 mm
• Optical material: Glass
• Coatings: Nano-C surface treatment and HMC (Hard Multi-Coating)
• Properties: Water-repellent, scratch-resistant coating, high light transmission
• Mounting: Screw-on (male thread compatible with 72 mm female lens threads)

How to use

Screw the filter onto the front lens thread until it seats gently—do not overtighten. Use the filter for outdoor and daylight shooting to reduce UV haze and for continuous protection of the front element. Clean the coated surface with a soft blower, lens brush and microfiber cloth; if necessary, use a lens-safe cleaning solution applied to the cloth, not directly to the filter. Remove the filter when attaching certain lens hoods or accessories that require the front element to remain unobstructed.

What to consider before purchase

• Confirm your lens has a 72 mm front thread size before buying
• Decide whether UV reduction or a different filter type (polarizer, ND) is needed for your shooting style
• Consider using thin/low-profile filters if you shoot at very wide angles to minimize vignetting

Usage recommendations

Use the K&F Concept Nano-C HMC UV 72 mm for regular outdoor use as a protective and clarity-improving layer. Store the filter in its case when not attached to the lens to preserve the Nano-C and HMC coatings and to prevent accidental scratches.
