PL 15mm or Voigt 17mm - Horror shoot in tight basement

[sigamy]

I'm shooting a no-budget horror short in a small basement. Also have some exteriors as they walk up to the house. I will have 3-4 actors in the basement scenes. I own the PL 25mm and plan to use it but I need a wide lens too.

Would I be better off renting the PL 15mm or the Voigt 17mm? I like the idea of the image I can get with the Voigt, but is it wide enough?

Any advice is appreciated.

I would consider the Tokina 11-16mm f2.8 II with a speed booster.

A 12 is not too wide on a gh4 check the Abel fov calculator - a 17 is a short mid really
