40D with UV/IR had no autofocus issue with custom white balance which I assume this camera will utilize; How does that differ from the 5D?

Modification Only if you endeavor for more Ha in photos; that's the sell point. So this filter doesn't ruin daylight spectral response? Have I missed something.

The camera is aimed specifically at astrophotographers. Particularly those who aren't interested in, or can't afford a CCD.
