It doesn't really matter what camera you use, it's more important to work out the correct exposure x reciprocity failure for your film. I find that the lower the ASA of the film the less you have to stand around in the dark waiting for an exposure due to a more forgiving reciprocity failure rate. So I used Ilford Pan F 50 for all of those. No ND filter, I just dropped the aperture to f16 and stood around for 15-20 minutes each time.
