Attached Link: IR thread

Hey Lou. Glad to hear someone else is interested in digital IR photography around here. Looks like you at around a -10/-11 EV lightloss. Substantial, but not too bad. My Olympus C8080 is at -13.5EV, but I still get decent results with a Hoya R72 filter. Take a look at the thread that was recently in the forum. It should help answer most of your questions. There is a link there to a camera comparision. Unfortunately, most newer digicams are less senstive to IR as Gongyla points out, but it can be worked around. I've still got that Canon 20Da on my wishlist though. ;]
