## Long description

K&F 77 mm UV filter (model SB9856) is a screw-in ultraviolet filter designed for lenses with a 77 mm filter thread. It reduces ultraviolet light that can cause haziness in outdoor and landscape photos while providing a basic protective barrier for the front element of the lens. The filter is mounted in a threaded metal frame that fits compatible lenses and maintains normal exposure and color balance under typical shooting conditions.
Advantages
This UV filter offers optical protection for the lens surface without affecting visible light transmission, allowing photographers to leave the filter mounted during routine shooting. The metal threaded frame ensures secure attachment and alignment with the lens, while the optical glass element reduces UV-induced haze in scenes with strong ultraviolet presence. The combination of protection and minimal impact on image quality makes it suitable for outdoor, travel and landscape use.
Suitable for
 Landscape photography in bright or hazy conditions
 Travel and outdoor shooting where lens protection is needed
 Everyday use to protect the front lens element from dust, fingerprints and light impacts
Key specifications
 Filter type: Ultraviolet (UV) screw-in filter
 Filter thread size: 77 mm
 Mount material: Metal threaded frame
 Optical element: Single glass optical element designed to reduce UV transmission
 Effect on image: Minimal change to visible light transmission and color balance
How to use
Align the filter's threads with the lens filter thread and rotate gently clockwise until the filter is snug; avoid overtightening. Use the filter as a protective first line against dust, moisture splashes and minor impacts, and leave it on the lens when shooting outdoors to reduce UV haze in distant scenes. Clean the filter surface with a lens-safe cloth or cleaning solution as needed to maintain optical clarity.
Usage recommendations
For best results, check that the filter thread size matches your lens (77 mm). Avoid excessive force when mounting or removing the filter to prevent thread damage. When photographing at very wide angles, verify that the filter does not introduce vignetting on lenses with short front elements; remove if necessary for specific wide-angle setups.
