## Summary description

K&F 52mm UV filter (model KF4181) is designed to reduce ultraviolet light and protect the front element of compatible 52 mm lenses. The filter features a blue multi-coating to minimize reflections and help maintain color fidelity. It mounts to the lens via a 52 mm thread and is suitable for everyday lens protection and outdoor photography in bright or hazy conditions.

## Long description

The K&F 52mm UV filter (model KF4181) reduces ultraviolet light reaching the camera sensor and provides reliable protection for the front element of lenses with a 52 mm filter thread. The filter uses a blue multi-coating designed to reduce internal reflections and ghosting while preserving color fidelity and overall image contrast. It is thin enough to fit commonly used lenses without causing vignetting and screws onto the lens via the standard 52 mm thread for straightforward attachment and removal.
Advantages
The blue multi-coating minimizes reflections and helps maintain natural color balance in bright or hazy shooting conditions. As a UV filter, it acts as a clear protective layer for the lens surface against dust, fingerprints and minor scratches without affecting exposure settings. The screw-in design ensures secure mounting and easy handling in the field.
Suitable for
Everyday protection of 52 mm front-element lenses
Outdoor photography in bright sunlight or hazy conditions
Landscape and travel photography where reduced UV haze is desired
Situations requiring additional protection during transport and use
Key specifications
Filter type: UV (ultraviolet) filter
Filter thread size: 52 mm
Coating: blue multi-coating to reduce reflections and ghosting
Form factor: slim profile suitable for use on wide-angle lenses
Material: optical glass mounted in a metal frame
How to use
Align the filter threads with the lens filter ring and gently screw the filter clockwise until it is snug; avoid overtightening. For removal, hold the lens firmly and turn the filter counterclockwise. Clean the filter surface with a soft blower, microfiber cloth and appropriate lens cleaner to remove dust and smudges. Use the filter as a permanent protective element or install it only when needed for UV reduction or transport protection.
Usage recommendations
Store the filter in a protective case when not in use to prevent scratches. When using on wide-angle lenses, verify there is no vignetting at the widest focal lengths; if vignetting occurs, use a thinner filter or a dedicated low-profile adapter. Clean gently with lens-specific tools to maintain the multi-coating performance over time.
