UV filter Kenko Celeste 40.5mm – Kenko 224260, screw-in lens filter for UV protection

Kenko Celeste 40.5mm UV filter is a screw-in glass filter designed to reduce ultraviolet light reaching the camera sensor while providing basic physical protection for the front element of lenses with 40.5mm filter threads. The filter is thin, lightweight and intended for use with mirrorless and compact system camera lenses where a 40.5mm thread is specified. It helps maintain image clarity in outdoor conditions by cutting UV haze and prevents scratches, dust and fingerprints on the lens front.

Advantages

The Kenko Celeste UV filter offers consistent UV attenuation across the visible spectrum without altering color balance or exposure. Its screw-in mount ensures a secure attachment to lenses with 40.5mm threads and the slim profile reduces the risk of vignetting on wide-angle lenses. As a transparent protective element, it preserves the original optical performance of the lens while simplifying cleaning and maintenance of the front glass.

Suitable for

• Mirrorless and compact cameras with lenses that accept 40.5mm screw-in filters
• Outdoor landscape and travel photography where UV haze is present
• Everyday lens protection against scratches, dust and fingerprints

Key specifications

• Filter type: UV (ultraviolet) screw-in filter
• Mount diameter: 40.5 mm (screw-in thread)
• Construction: thin/slim profile suitable for wide-angle use
• Optical material: coated optical glass (transparent transmission)
• Finish: metal screw ring for secure attachment

How to use

Align the filter's screw threads with the lens filter thread and rotate clockwise until finger-tight; avoid overtightening. Use the filter continuously when shooting outdoors to reduce UV haze and to protect the front element from mechanical damage. Clean the filter with a blower, lens brush and microfiber cloth or lens cleaning solution as required. When removing, rotate counterclockwise and store the filter in its protective case to prevent scratches.

Usage recommendations

For best results, leave the Kenko Celeste UV filter mounted during normal shooting to ensure continuous protection. On lenses with very short focal lengths, check for vignetting; if present, use a dedicated slim or specialized filter holder. Regularly inspect and gently clean the filter surface to maintain optical clarity.
