About Tiffen T 1/2 Infrared Filter

From the renowned brand Tiffen comes the WW T 1/2 IR Filter, meticulously engineered to enhance the performance of high-end digital cameras like the ARRI Alexa and Sony EX Series. This 138mm Round T 1/2 IR Filter, with a 0.5 stop, is specifically designed to broaden the color gamut and amplify red response, thereby delivering vibrant and true-to-life images.

One of the key features of this filter is its ability to eliminate Far Red/Near Infrared contamination, a common issue in fabrics containing certain industrial dyes. With the T 1/2 or T1 filter in place, the camera effortlessly captures subtle red hues, ensuring the delivery of crisp blacks and a wide color gamut, all with minimal light loss.

The Tiffen WW T 1/2 IR Filter is crafted using Tiffen's exclusive ColorCore technology. This unique process encapsulates each effect between two pieces of glass, allowing Tiffen to grind and polish both surfaces. This results in perfect parallelism and worry-free handling for the cinematographer.

These filters are constructed with Water White glass, ensuring superior optical clarity. It's important to note that these filters do not contain a dichroic coating, which means they will not vignette green, magenta, or cyan at wide angles. For optimal results when using ND's, we suggest pairing with the Tiffen Full Spectrum IRND's.

In conclusion, the Tiffen WW T 1/2 IR Filter is a powerful tool for photographers and cinematographers seeking to capture stunning visuals with enhanced color accuracy and minimal light loss.
