What type of lens would work best for cinematic filming with a dslr?

I would like to know about any high speed nikon lenses that would be best for filming. I only have a kit lens at the moment because I just bought my camera. I will be getting a 50mm f1.2 (Fx lens for portraiture) and a DX 50mm f1.4

P.s. I have a Nikon D7000, and I would prefer hearing about fixed focal length lenses (primes I believe) and I would like recommendations on what to get to be a found footage horror in dark light.

Also; If possible, I'd prefer hearing about lenses I can keep in infinity without having to focus often during the movie (Like wide angle mayybe?)

Zeiss makes great lenses for shooting motion on a Nikon or Canon for that matter. They aren't cheap but they are great. The 85mm f1.4 is really nice and the wide lenses are also fantastic.
