I been thinking about upgrading to the 50D. Wanting to know what do I have to upgrade on the Canon Software that can with the 30D. I currently on that and Rebel XT. I just light room and CS3 for editing. I ask this because I don't want to download a lot of extra software. I use the remote shoot in the EOS Utility and that's about it for canon software. I currently have Zoom browser 6.0.1.
