A Question on Film Formats

[Giray Izcan]

Hello, I have posted on cinematography.com a few times. I have an NPR ultra 16 camera. I shoot with Rokinon lenses. I have a short film project intended for short film festivals. My question is if the image quality difference between super and ultra 16 noticeable under same circumstances I.e. lenses , lights, etc.? If I shoot on photo lenses, can I achieve similar quality to pl s16 lenses since I use the Venter of the lens? I am trying to figure out if ultra 16 with stills primes would be noticeably less quality than s16 with 2k scanning? Or should I get a PL zoom lens like Canon 8-64? I've shot a few different test films and seems like Rokinon yields pretty contrasty , sharp and modern look but would like to get professional's opinions. In sum, can I roughly get the same image quality as s16 with u16? Thank you.
