Re: Canon Rebel SL1 vs Rebel XTi for Infrared photography
I could see using Liveview for better composition and guaranteed focus, but not for the IR \"look\". Just like with visible spectrum photos, the best results are by shooting raw and managing settings after the fact.
Regarding lenses, I am not sure how IR is going to change characteristics of the optics. If a lens has bad corners, it will regardless of IR or visible spectrum.
I would personally convert the XTi. I had an XTi that I converted, and it was alot of fun and worked quite well for my uses. You could also buy something like the 40D (first xxD body with live view, I believe) for pretty cheap and send that in.
