If your lenses truly have the depth of field they claim, and I imagine they do
at 12mm, then you have nothing to worry about.  IR has a fairly negligible
focal shift and you would only have to adjust for it when using a small depth
of field and in close up situations.  I used to shoot IR all the time with a
24mm lens set at f11 and never bothered with the focus correction.

It's your saving grace.
