Hoya 0653 49mm HMC Screw-in Red Filter

The Hoya 49mm HMC Screw-in Red Filter is a color contrast filter designed primarily for black-and-white photography. By absorbing blue wavelengths and transmitting red light, it dramatically darkens blue skies and water while lightening red and orange subjects. The result is pronounced tonal separation — clouds pop against near-black skies, and foliage gains stronger contrast against flowers and other warm-toned elements. This makes it a staple filter for monochrome landscape and architectural photographers who want bold, graphic results straight from the camera.

Beyond creative black-and-white work, Hoya identifies this filter as useful in scientific photography and for copying blueprints, where its selective color transmission improves legibility and contrast of specific details. The filter features Hoya's proprietary HMC (Hoya Multi Coating), applied to both glass surfaces to reduce reflections to a minimum and maintain high light transmission — an important consideration given that red filters inherently require additional exposure. The 49mm screw-in mount threads directly onto compatible lenses, and the glass-and-metal construction is consistent with Hoya's reputation for optical quality in the filter market.
