>camera's AF system only sees visible light.
close but wrong
your AF system is calibrated to visible light. IR has a substantial enough difference in refractive index to visible light that it will be out of focus if you're using body AF
if your camera has live view AF, it will focus correctly because it uses local contrast points which will focus correctly even with IR

don't filter in body, it doesn't make sense. There are enough IR filters that you can stick on the lens that anything other than full spectrum doesn't make sense

this one's really great

you can see short IR, there are just very few situations where your retina's not getting absolutely assaulted by visible and UV while short IR is plentiful enough to see
You can even "see" all the way up to X-rays as well.

is this Aerochrome or just a LUT?
