Here's the short story. I'm planning on having a camera converted to infrared capture sometime soon. Soon after that I plan on buying more of a pro-level dslr that I hope will last me at least a few years. So it would be nice if they were from the same system. It's not entirely necessary though because I'm more interested in quality of the images than whether or not I have to buy the same lens twice. Aside from that, my uses for the infrared will probably differ from my uses for the other that I would wind up needing different lenses anyway. So my question is... has anyone had better luck with Nikon vs Canon in the converted-to-IR sense of things? I plan on getting just the basic conversion so that I can shoot color and b/w IR... but I'll honestly probably be using the b/w the most. I like super contrasty shots versus stuff with alot of gray. The models I've been mulling over are the XTi or 40D from Canon. Only thing I'm not sure of on the 40 is it's tendancy towards ISO 400. I'm more used to the 100 mark with my tastes in b/w. And for Nikon probably a D80... I want to avoid the D40/x if possible. Any thoughts from those with experience?
