Herm,
    Yes you can switch camera bodies between color shots and TP.  I sent my
2 camera bodies to Ted at Hutech and he calibrated a knife edge focuser for
me. Beauty of it is, One camera has a slightly longer distance to the film
plane than the other so I use that one for the color film and the one with
the shorter distance for the thicker color film. Both are in perfect focus
even at the fast f/3.3 of my Tak.
