Hoya Y1POL049 49mm Linear Polarizing Filter

The Hoya Y1POL049 49mm Linear Polarizing Filter is a practical tool for photographers who want to manage reflections and enhance image quality in-camera rather than in post-processing. By selectively filtering light waves, this filter reduces unwanted glare from non-metallic surfaces such as water, glass, and wet foliage, resulting in cleaner, more vibrant images. It also deepens blue skies and increases cloud contrast, adding visual drama to landscape and outdoor photography without altering the overall color balance of the scene.

The filter features coatings on both optical surfaces to suppress internal reflections and maintain light transmission, helping preserve image clarity. A rotatable mount lets you fine-tune the polarization effect by turning the front ring to match the lighting conditions of your scene. At 49mm, it threads directly onto compatible lenses without adapters. It is important to note that this is a linear polarizer, specifically designed for use with manual focus cameras and lenses — autofocus and TTL metering systems on modern cameras may not function reliably with a linear polarizer, so photographers using autofocus equipment should consider a circular polarizer instead.
