Tiffen 305SHM 30.5mm Standard Hot Mirror Filter

The Tiffen 305SHM 30.5mm Standard Hot Mirror filter is a specialized optical accessory designed to address a specific challenge in digital imaging: infrared light contamination. Some digital camera sensors exhibit heightened sensitivity to infrared wavelengths, which can result in inaccurate color rendition—typically manifesting as unwanted warm or magenta color shifts, particularly noticeable in skin tones and neutral-colored subjects. The Hot Mirror filter works by reflecting most infrared light before it reaches the sensor, allowing only visible wavelengths to pass through for natural, true-to-life color reproduction.

Manufactured in the United States, this filter carries Tiffen's long-standing reputation for optical quality in the photographic filter market. The 30.5mm thread size is relatively uncommon and typically found on compact cameras, smaller video lenses, or specialty optics. Photographers and videographers who have identified IR contamination as an issue in their work will find this filter to be a straightforward, screw-on solution. Its slim profile and light weight mean it adds virtually nothing to the physical footprint of the lens it's mounted on, making it a practical addition to a kit bag for those who need reliable infrared correction.
