Happy to see that the 40D format is supported by Leopard. So iPhoto, Preview Image Capture and presumably Aperture, etc all work fine with the 40D now. Does anyone know if iPhoto '08 still does that stupid JPEG conversion when editing RAW files? EDIT: I see that according to the iPhoto help, it does still do a conversion to JPEG when you edit a RAW file. They tout it as a feature (editing and JPEG conversion in one step!) when really it's an annoyance.
