Kenko Smart C-PL Slim 40.5mm Circular Polarizer Filter

The Kenko Smart C-PL Slim is a high-quality circular polarizer filter designed for lenses with a 40.5mm filter thread. It effectively reduces reflections from non-metallic surfaces such as water and glass, enhances color saturation, and darkens blue skies for more dramatic landscape photography. The slim aluminum frame minimizes vignetting on wide-angle lenses, while the multi-coated optical glass ensures excellent light transmission and flare resistance.

Advantages

This filter offers adjustable polarization by rotating the front ring, allowing precise control over reflections and color intensity. The slim profile is ideal for wide-angle lenses, preventing dark corners in your images. Multi-coating reduces ghosting and flare, maintaining image clarity. The durable aluminum frame is lightweight yet robust, and the included plastic case provides safe storage.

Suitable for

• Landscape photography to enhance skies and foliage
