Mike, you're out there fighting the good fight against movies shot wide open in broad daylight with 500T! In all seriousness, I didn't start regularly working with ND filters until my very first visit to FPP's Butler HQ and you were setting up lights and filtration for a stills shoot!
Greetings Mike, I use 35mm Nikkor lenses on my Bolex H16 Rex 5. I always wondered if apertures for 35mm and C-mount lenses were the same. For example, if I use a 35mm lens at f/4, the opening is much bigger than if I use a C-mount lens. Does that extra light going through the lens have to be compensated for? Since 1/3 of the light is diverted to the viewfinder by the Bolex prism, perhaps I should open up a stop? I'd be interested in hearing what you have to say about this...Maybe this question could be answered in the upcoming Show....What show?

I imagine there are steps down rings which can hold your filters in place even though larger than the lens circumference.
I have yet to see a cine lens that stops down to f32.

Question: Are the treads on the lenses universal? Could I put that lens on another make of camera, say a Bell & Howell or whatever?
Thread size will vary. I usually hold the filter over the lens.
Do ND Filters come with every movie camera or are they sold separately? Also when were they invented?
Generally, ND filters do not come with the camera.
If only the ND filters fit the lens...
