Description
The Tiffen 77mm Infrared Filter targets infrared contamination at 680nm, keeping blacks true and removing unwanted red or green colour casts — particularly useful shooting against dark fabric where IR bleed is most visible.
Digital CCD/CMOS sensors are inherently susceptible to infrared contamination; the built-in IR-absorbing filters most cameras carry can’t cut off sharply without also excluding visible red, so some IR always leaks through. Built with Tiffen’s ColorCore technology — the filter material laminated between two pieces of optical glass, ground flat to 1/10,000th of an inch and mounted in a precision aluminium ring — the filter transmits 98-99% of light with anti-glare, anti-reflective performance.
