Paul,
I use a variety of Nikon cameras for IR photography (HIE): Nikkormat
Ftn, Nikkormat EL, Nikon EM and Nikon 801S(8008S). The first 3 cameras
have a presssureplate that is almost smooth with a lot a very tiny
dimples. Never noticed any 'shadow marks' on my negatives. As far as I
know the two Nikon's 801S have more pronounced marks on the pressure
plate. I can't check it now because both cameras are loaded with film!
Also the Nikon 801S never gave me any pressure plate problems. So my
conclusion is: excellent cameras for IR. Haven't got any idea about the
latest Nikons like F4, F90(X), F5 and F100. As you already suggested you
can cover any pressure plate by tape. What you said about the Nikkormat
EL (a lovely camera and one of my favourites) interests me. Why
shouldn't you fix a filtersheet between the filmrails? It won't do any
harm to the camera. You can remove it any time and see no traces
whatsoever! My experience is that a #87 filtersheet (0.1 mm) fits easier
than a #87C sheet (0.4 mm). The latter is thicker and will be scratched
quicker. Also I believe that a #87C sheet gives less contrast and less
sharpness than a #87 sheet. I can't prove this, I base my opinion on a
rough judgement of my negatives. By the way a discussion about mixing
martini and drinking gin sounds is sometimes also very refreshing. --
