However, I don't have the IR filter so I can't give any personal stories. Photonics Spectra covered the issue in more technical detail back when it first broke in 1998, although I couldn't find a link to the article on their web site. Tony

It seems that the 'night vision' feature picked up either heat or ultraviolet reflection (can't recall which). The temperature of certain clothing materials meant that they didn't get 'seen'. On another web site in Japan in 1999, they offered a special lens that was supposed to expand the range of reflection such that certain types of material appeared no to be there. It was all to do with the wave-length of the light or the heat radiated. These lenses were ridiculously expensive but I guess they believed there was a global market. My bet would be they might have sold zillions of them in Japan, and most parts of Arabia. Cheers Doug M

Finally, there was a big scare in Hong Kong, IIRC -- with women not likely ANYONE with a camcorder (IIRC there some camcorders were smashed). Tony
