Will, 5219 extend the effective f-stop range of anamorphics?

So that would mean that although you are not changing the stop, you are able to shoot a lower light levels as though you had changed the stop, but were able to retain the same DOF at the previous stop, effectively lowering the stop the lens is capable of shotting at? Would that mean you could also shoot at a higher stop, push the film one or two stops and get the same effective stop with a greater DOF that if you had stopped it down? I mean obviously this is true, but are you getting pretty much the same look as if you used say a fast anamorphic stopped down to the equivalent pushed stop or are there aesthetic differences with the newer film like contrast compromises and grain issues? (this probably should have gone in the film processing category but I thought I had a lens question here. I also know this is somewhat basic information I should already know but I'm just trying to verify I have it exactly correct in my own head)
Well, 5219 is ISO500, same as 5218, so, using either one, you'd get the same f-stop for a given set up. Apparently 5219 is a little less grainy, so you might be able to push it a bit further than 5218, particularly if you're shooting anamorphic, which is inherently cleaner than super35.
So, it doesn't "extend the f-stop range" but it might let you use a bit less light with similar results. But, the thing is, it doesn't appear that 5219 is that much cleaner than its predecessor so it makes next to no difference. Why not just shoot super35 and rent sharp lenses? I doubt those anamorphic lenses are sharp wide open, and stopped down a stop or two you would need a whole lot of light, and this would probably increase your rental cost far beyond renting faster spherical lenses for the same amount of time. Than again I don't know much about this since I've never had the chance to shot 35mm yet!

Anamorphic requires more light generally, so you just have to bite the bullet and find more light for your night work. Certainly Super-35 might make more sense for a night-heavy production with minimal lighting, but you have to factor in that anamorphic allows you to just cut the negative and make a contact print for projection, if you're aiming to make prints.
