Hoya HPUX405 UX Circular Polarizing Filter 40mm

The Hoya UX Circular Polarizing Filter (40.5mm) is designed to manage reflections from non-metallic surfaces such as water, glass, and foliage while simultaneously boosting colour saturation and contrast. This makes it a practical tool for landscape, outdoor, and architectural photography where unwanted glare can flatten an image. The rotating frame gives photographers direct control over the intensity of the polarizing effect, allowing you to preview and fine-tune the result in real time through the viewfinder or on your camera's LCD.

A key design consideration is the slim filter frame, which is engineered to minimise vignetting when used on wide-angle lenses—a common issue with standard-thickness polarizers. Despite the reduced profile, the frame still accommodates a standard lens cap, so there is no need to remove the filter for storage or transport. The water-repellent coating adds a layer of practicality for shooting in damp conditions, making it easier to clear water droplets and maintain a clean optical surface during outdoor sessions.
