Its insane (cooling a PC with mineral oil), have a look.
Just
think about it, a 40D in a plastic bag, a good one, with 2 tubes out of it. One for oil in and the other out going to a tank (or just past a peltier) that cools the oil to -30deg C (oil freezes well below zero). I bet the shutter will still work.
Do you think the oil between the sensor and the back of a FR would cause distortion? mmmm, some APOs use oil, cant be that bad.
Im tempted to sacrifice my 40D in the name of science, anyone think of a reason it wont work?.
