Cokin Nuances Extreme IR721 L (Z)

The infrared filter Nuances Infrared 720 is designed for the filter-holder EVO L. It cuts UV and visible lights and starts transmitting from the deep red (50% at 720nm). You have to use it in the first slot of the filter-holder in order to prevent a possible incident light going through the filter-holder and the surface of the filter. The infrared filter Nuances Infrared 720 is made of a mineral glass ensuring the full conservation of your lens optical resolution. Furthermore the transmission of the filter into the infrared spectrum has been improved to reach a maximum of approximately 98% at 950nm. For users of a Cokin Creative Z-Pro Series filter-holder, the infrared filter is provided with a foam ring to maintain a good airtightness between the filter and the body of the filter-holder. However we recommend using the filter-holder EVO L.
