I know they make infra-red filters for the d70 (and everything else). I was just wondering, anyone here ever use one? How much are they? Are they as super-neatotastic as the pics they make?! And why did I use redx? Cuz it's cool and I hadn't seen it before. Anyway! If anyone has any experience, please point me in the right direction... I'm looking to get a shiny new toy, and it's this or an accessory flash. Or, if I get my job, BOTH!
