Cokin P007. Filter size: 67 mm Product colour: Red. Product Family P007. Collection Model Cokin P007. P007 - Infrared. This filter is equivalent to the Kodak 89B written filter with a spectrum transmission of 50% at 720 nm.
An interesting filter to use, requires liveview and exposure sim to be really effective. infra red focuses slightly differently to normal light, use f8+ to get a decent depth of field. produces an unusual view of the world, which requires a bit of manipulation in a photo editor. Use RAW fro the best results.
Being part of the Cokin system it is easy to use an light weight.
Good value for money.
