Camera protection filter Kenko KEDSMPR40 — 40.5 mm

Kenko KEDSMPR40 is a 40.5 mm camera protection filter designed to protect the front element of compatible lenses from dust, scratches and minor impacts. The filter has a slim-profile metal frame in black finish and comes as a single-piece pack. It mounts to lenses with a 40.5 mm filter thread and provides everyday physical protection without altering exposure settings or changing image characteristics.

Advantages

The slim frame reduces vignetting on wide-angle lenses while maintaining reliable mechanical protection. Optical glass preserves image clarity and color neutrality so the filter does not affect exposure, contrast or color balance under normal shooting conditions. A single-piece design and standard screw mount make it easy to attach and remove, and the black finish minimizes reflections and stray light.

Suitable for

• Travel photography where lens protection is required
• Street and documentary photography with frequent lens handling
• Outdoor shooting in dusty or variable environments
• Daily use to prevent scratches on the front element during storage and transport

Key specifications

• Filter type: Camera protection (clear)
• Mount thread diameter: 40.5 mm
• Frame design: Slim-profile metal frame
• Finish: Black
• Pack quantity: 1 piece

How to use

Screw the Kenko KEDSMPR40 filter onto the front thread of a lens with a 40.5 mm diameter until it is snug; avoid over-tightening. Use the filter continuously to protect the front element during shooting, transport and storage. When cleaning, remove the filter and clean the glass with a soft microfiber cloth or lens-cleaning solution, then reattach. Store the filter in its protective case when not in use to prevent dust and scratches.

Usage recommendations

For best results, use the slim-frame protection filter on lenses where minimal added thickness is important, such as wide-angle optics. Regularly inspect and clean the filter surface to maintain image quality; replace if the glass becomes severely scratched or damaged.
