Are Nikon finders interchangeable between different models (F, F2, F3, etc) or specific to the model? I want to acquire a waist level finder for my F2 and wanted to know which models will fit.
The F and F2 have the same mechanical catch and release so that the F's plain prism fits the F2 but the Nikon (or Nikkor) nameplate on the F would have to be removed in order to use the F2's which has the Nikon nameplate on the finder instead of the body.
You can read about the F2 non metered finders here -> Link
