I've got a 77mm B+W brand #93 infrared glass filter that I don't need. I've only used it once to test on a digital camera, but I intended to use it for infrared film. It passes light starting around 800nm (far infrared, completely nonvisible to the human eye), which is at the tail end of what every currently produced IR film uses. It's still useful with digital cameras, though. I've tried it with a Canon 350D and an L lens, and it worked as I expected it to. It's a very good filter for producing monochrome infrared images.
It's in perfect condition, and costs about $168 brand new. I'll let it go for $120. If you've got any questions about digital infrared photography, ask away, I've got a lot of experience with it.
