Lens filter set Kenko 40.5mm — Kenko 234296 (multi-coating, screw-in)

Kenko 40.5mm lens filter set is a compact, screw-in multi-coating filter kit designed for lenses with a 40.5 mm thread. The set combines protective and image-control filters to preserve front element integrity, reduce unwanted reflections and maintain color fidelity. Multi-coating minimizes flare and ghosting while keeping light transmission consistent, making the set suitable for everyday outdoor and travel photography with compact and small mirrorless/interchangeable lenses.

Advantages

The multi-coating applied to each filter surface reduces internal reflections and helps retain contrast in backlit or high-contrast scenes. A UV/protect filter included in the set provides physical protection for the lens front element without altering exposure, while additional standard screw-in filters offer practical image adjustments such as glare reduction and improved color balance. The screw-in 40.5 mm design ensures a secure fit and low profile that preserves lens handling and does not interfere with lens caps or hoods intended for compact optics.

Suitable for

• Compact cameras with 40.5 mm filter thread
• Small mirrorless cameras and interchangeable lenses with 40.5 mm thread
• Outdoor travel and street photography where lens protection is needed
• Scenes with bright light or reflections where contrast improvement is beneficial

Key specifications

• Filter thread diameter: 40.5 mm (screw-in)
• Type: multi-coating screw-in filter set including protective and image-control elements
• Coating: multi-layer anti-reflective coating on filter surfaces to reduce flare and ghosting
• Mount style: low-profile metal frame compatible with compact lenses
• Optical effect: UV/protection plus additional standard effects for glare reduction and color/contrast control

How to use

Carefully screw the selected 40.5 mm filter onto the front thread of the lens until it is finger-tight; avoid overtightening. Use the UV/protect filter as a permanent protective layer to prevent scratches, dust and moisture on the lens front element. Swap to other included filters when you need to reduce glare or adjust contrast and color balance. Clean filters with a soft microfiber cloth or lens cleaning solution designed for optical coatings to maintain clarity and coating performance.

Usage recommendations

When using the filters outdoors, store them in their protective case when not in use to avoid scratches. For long exposures or critical low-light work, remove unnecessary filters to minimize additional glass surfaces. Verify compatibility with lens caps and hoods before leaving for a shoot to ensure the filter does not block accessories.
