however, get a Nikon or Leica R T-adapter and then Nikon or Leica R
to M. I have never seen a T-adapter for Leica M directly.
The M8 has decent IR sensitivity, but it still has a weak IR filter.
A modified Canon or other camera with the IR filter removed has about
3 stops more sensitivity to light of about 720nm.
