I currently have the 20mm pancake lens and have been eyeing either the Nokton 25mm or Sigma 30mm 1.4 to possibly replace it. After looking at various video it seems that either of those lenses can really get that "film" or "cinematic" look, and I think I might like a closer focal length better. Not sure if I should get either the Nokton the Sigma with adapter, or just keep the 20mm. I'm currently going crazy trying to make up my mind. Has anyone used a combination of these lenses? Any feedback for me?
