join:2005-03-29 | IR Filters Hi - Does anyone have any experience with IR filters? The standard seems to be the Hoya, but several others are available, such as Kenko and Suntec. I's appreciate any information you might have. | |

noting the graphs, showing the curves comparable to the normal hoya / nikon numbering system, where the filter number is the first two digits of the nm at 50% transmittance.
(example L39 is at 50% transmittance at 390 nm) | |

| I've got a couple but can't remember what brand they are, I think they are Hoya, and it's been my experience that like anything else, you get what yoiu pay for.
