Monochrom Type I and UV/IR Cut Filters

This may seem like a strange post but I'm considering getting an M8, which would require UV/IR Cut filters, and still keeping  my Monochrom Type I.  I'm wondering if it would affect the focusing on the Monochrom Type I,  if I use these filters on the lenses?

Not really ... the viewfinder is separate to the lens and is optical and even if you have lens cap on, you can still focus. 

Or do you mean does the filter affect where the focal plane of the lens falls? In which case answer is still no, because the lens designers designed the focal plane for visible light and the IR is cut out.  

If you use the M8 for IR photography, then you have to adjust the focus away from the optical finders decision of correct focus (IR light is of longer wavelength).
