Just to catch you up; I did tons of infrared work with the Rebel XT after it was modded by LifePixel.com (72nm). Then I sold it because I wanted some more pixels; and the process really did work so well. The 450D arrived from Amazon in less than one day; and it’s now sitting in the box waiting to go off to LifePixel tomorrow (and I even paid the extra $65 for 5 day turn around).
I have to admit, that little camera does bug me. Hard to get used to after handling the 10d-50d series. I remember having the same feeling when I first got the XT and that eventually that went away.
But it makes more sense to get the extra pixels for what are usually static scenics in the infrared world; and where the ability to focus quickly or have a great viewfinder isn’t everything.
Well anyway, there you have it. There’s always compromises. If unexpected money comes my way, then I will end up with the 5D II. In the meantime, these two cameras are a good combination and easy to fit with my lenses in a normal camera bag. It just irks me that they don’t use the same size cards… but there you have it.
