## Summary description

K&F 55mm UV filter is an optical protective filter designed to mount on lenses with a 55 mm thread. It reduces ultraviolet light entering the lens, helping to prevent haze and improve clarity in outdoor photography while providing surface protection against dust, scratches and fingerprints. Suitable for everyday use on compatible DSLR and mirrorless camera lenses.

## Long description

The K&F 55mm UV filter is an optical protective filter designed for lenses with a 55 mm thread. It reduces ultraviolet light reaching the image sensor or film to help minimize atmospheric haze and improve image clarity in outdoor photography. The filter also provides a physical protective layer for the front element of compatible DSLR and mirrorless camera lenses, shielding against dust, light scratches and fingerprints without affecting exposure settings.
Advantages
The glass is treated to transmit visible light while blocking UV rays, which contributes to clearer distant details in daylight scenes. The slim, threaded metal mount fits standard 55 mm lens threads and maintains parfocal balance when stacked with other filters. Because it is an external protective element, the filter preserves the original lens coatings and optics from direct contact with environmental contaminants.
Suitable for
Outdoor landscape and nature photography to reduce haze
Everyday protection for front lens elements on 55 mm thread lenses
Travel and street photography where quick lens protection is needed
Situations requiring consistent color transmission without ND or polarizing effects
Key specifications
Thread diameter: 55 mm
Function: ultraviolet light reduction and lens surface protection
Mount: slim metal threaded ring compatible with 55 mm filter threads
Optical material: coated glass designed for visible light transmission
Effect on exposure: neutral (no significant light attenuation)
How to use
Screw the filter onto the front of any lens with a 55 mm filter thread until it is secure but not overtightened. Compose and focus as usual; the UV filter works passively and does not change autofocus or exposure settings. Clean the filter surface with a microfiber cloth or lens cleaning tools to maintain image clarity. For stacking with other filters, ensure the slim mount avoids vignetting on wide-angle lenses.
Usage recommendations
Use the filter primarily in daylight or high-UV conditions to reduce haze; remove or keep it depending on optical needs when using specialized filters (e.g., polarizers or ND filters) to avoid unwanted interactions. Store the filter in a protective case when not in use to prevent scratches and dust accumulation.
