## Summary description

## Long description

K&F Concept Nano-C HMC UV 49 mm is an optical protective filter that reduces ultraviolet haze and provides front-element protection for lenses with a 49 mm filter thread. The filter uses multi-coated (HMC) glass combined with a Nano-C coating to limit light reflections and repel dust and moisture while maintaining image clarity and accurate color reproduction. It is intended as a low-impact optical accessory that stays on the lens to guard against scratches, fingerprints and incidental contact during landscape, travel and everyday photography.
Advantages
The multi-coated HMC glass reduces internal reflections and flare, while the Nano-C surface treatment improves water and oil repellency for easier cleaning. The slim filter ring design minimizes vignetting on wide-angle lenses and preserves lens performance by maintaining image sharpness and natural colors. The filter adds mechanical protection to the front element without altering exposure or autofocus behavior.
Suitable for
Landscape and outdoor photography to reduce UV haze
Travel and street photography for continuous front-element protection
Everyday shooting where lens protection against dust and scratches is required
Key specifications
Filter size: 49 mm thread
Filter type: UV optical filter
Glass: multi-coated (HMC) optical glass
Coating: Nano-C hydrophobic and oleophobic surface treatment
Frame: slim metal filter ring designed to reduce vignetting
Function: reduces UV haze while providing mechanical front-element protection
How to use
Screw the filter gently onto the lens front until it is securely seated; avoid cross-threading. The filter can remain mounted during shooting and does not require exposure compensation. Clean the coated surface with a microfiber cloth and, when necessary, use lens-cleaning solution designed for coated optics. Store the filter in its protective case when not in use to prevent scratches.
Usage recommendations
Use the filter on lenses with a 49 mm thread and verify compatibility with lens hoods or stacked filters to avoid vignetting. For best results, keep the Nano-C coating clean and avoid abrasive materials when wiping the glass.
