The IR sensitive 20D - Photography

When Canon brings this out, I wonder if it will be like the Sony vidcam that could see through some clothing? Remember it? -Rich...

    The Canon EOS-20Da isn't really IR sensitive, but it has enhanced Red
    sensitivity which makes it more sensitive for Hydrogen Alpha
    emissions.

    It's not an IR camera. Canon has modified the IR filter so that H<alpha> at
    636nm will pass. This is visible light, or red nebulae.

    Thanks. I guess the only one that has sensitivity that extends
    into the infrared are the modified Rebels some people have
    made. They removed the IR rejection filter.
