I'm looking for an alternative to my elan 7n for use with IR film (I have a couple of nice eos lenses, so I've got no desire to switch 35mm systems). I've read the pages here at photonotes: http://photonotes.org/articles/eos-ir/ Can anyone confirm that the EOS 10S works well with kodak HIE? What about the 650? I've seen both of these used in a shop here, and I'm considering picking one up. The main issue I'm wondering about (not mentioned by the photonotes page) is the big gaping hole in the back that displays the film cartridge loaded - does this interfere with IR, and is there an IR-opaque material I can put over it if necessary? Thanks. Any suggestions welcome.
