UV filter Kenko 52mm 225293 — ultraviolet protection filter for camera lenses

The Kenko UV filter 52mm (model 225293) is an ultraviolet protection filter designed for camera lenses with a 52 mm filter thread. It cuts ultraviolet light that can cause bluish cast and reduced contrast in outdoor images, helping to produce clearer, cleaner photos in daylight conditions. The filter also acts as a transparent protective layer for the front element of the lens, guarding against dust, fingerprints, scratches and minor knocks without altering color balance or exposure.

Advantages

This UV filter provides passive ultraviolet reduction while remaining optically neutral, so it preserves the original color balance and exposure of the lens. Constructed to sit flush on lenses with a 52 mm thread, it offers front-element protection and easy access to lens caps and hoods. The slim-profile design minimizes vignetting on wide-angle lenses and maintains image sharpness when properly mounted. The filter is lightweight and easy to carry, making it suitable for everyday outdoor shooting.

Suitable for

• Lenses with 52 mm filter thread
• Outdoor landscape and travel photography
• Protection of front lens element during transport and everyday use
• Photographers seeking reduced atmospheric haze and neutral color reproduction

Key specifications

• Filter type: Ultraviolet (UV) protection
• Mount diameter: 52 mm
• Glass: Optical filter glass designed for minimal color shift
• Frame: Slim-profile metal ring to reduce vignetting
• Finish: Neutral transmission across visible spectrum

How to use

Screw the filter onto the front of any lens that has a 52 mm filter thread until it is snug but not overtightened. Use the filter on clear, sunny days or in hazy atmospheric conditions to reduce UV-related haze and improve clarity. The filter can remain attached during most shooting situations as it does not affect exposure settings; remove it only when using specialized filters or when stacking multiple filters causes vignetting. Clean the filter surface with a soft microfiber cloth and appropriate lens-cleaning solution to maintain optical performance.

Usage recommendations

When mounting or removing the filter, hold the lens steady and turn the filter ring rather than twisting the lens barrel. Store the filter in a protective case when not in use to avoid scratches. For best results, combine the UV filter with routine lens maintenance and avoid excessive force when tightening.
