First Lens for Filming on a DSLR?

I'm looking to get into film. I have recently purchased a Nikon D5300 and am looking for a lens to pair it with. I'm also a keen photographer and would like to keep that option open. At the moment I only have one lens, a 22-88mm.

As someone looking to get a grasp of film and photography in ONE lens what would your recommendation be? My research has left me between the 35mm and 50mm 1.8. I feel the 35mm lends itself better overall to both Film and Photography.

Could anyone add anything to what I've found thus far?

I think a 35mm 1.8 would be good. Def. Stick with a prime lens and not a zoom.

Get a 35mm f/1.8 and a Nikkor 24-120 f/4 ED VR
