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

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.
