Send your XT to LifePixel (www.lifepixel.com). They'll swap out your
senser filter with an R87, or other specialty IR filter they sell.
You'll then be able to shoot 1/400 @f8 AND look through your viewfinder.

Hello, everybody.
I just bought a Tiffen R87 filter and made a couple of test shots. My rudimentary measures say there is a 16 (yep, sixteen) step compensation, which is substantially more than I had read and expected. I still have to test it more under different conditions, but If I want interior or studio shots, or even live subjects, then I'll be in trouble with such density. I may become the most famous IR rocks photographer! ;)
Anyway, the main thing I would like to ask the forum is this: is Depth Of Field the same in IR than it is in visible light?
Incidentally, I now remember the lenses of yore had a red mark that placed infinity a bit farther than visible. I guess I''ll have to practice a lot this weekend! ;)
BTW, I use a Canon Digital Rebel. I have an XT and bought a T3i (but still in the box).
Any comments and advice to this curious IR neophyte are welcome.
