The pitch difference is 4 ten thousands of an inch. per perf or 3.2 thousands of an inch for an 8 perf still frame... Don't think it will upset any still camera. But I have only used BH1866 Movie film in Pentax SLRs, Minolta SLRS, (x series) a Canon Manual Focus SLRS (a series) Canon EOS Slrs and a few odd other cameras.
You would have to take more care with Movie Cameras to give them what they expect as over time the slight difference may cause a slight unsteadyness in consecutive images. something that would not even be detectable in a still camera.
