Does anyone know or would say the ASA equivalent is for the Sony Z1/FX1?
This has been addressed here already - do a search!

Problem is that the exposure index of a video camera is not a perfectly skiable MTF slope as it is with film so the answer to the question has to do with how much llight you are talking. Exterior will give you a different exposure index (ASA is not a correct term to use in video language although everyone does) than you will get in an interior. But then again to make sure you are getting at least 75% MTF outdoors you want to use the ND filter in camera and if necessary additional add-on ND filters to keep your lens wider than 5.6 or else you throw away resolution.

As I took some time to raise this question, it took some time to get answers.
But my location findings check to what you say. Someone mentioned a 160ASA equivalence (even if I know I shouldn't use that), which falls within the +/- 2 stops you mentioned for safe shooting.
This project should be screened in TV only, so there shouldn't be much of a problem.
This week I should have an interior shooting, where I will use the 100 mark you advice on. That project will be transferred to film.
