Is this vintage lens the perfect focal length?

Konica Hexanon AR 40mm f 1.8 is great for daylight video. But how does it perform at night? This lens is very characteristic, and may not be for everyone. Lens review from Bergen airport Flesland. Tiny and affordable manual lens. Shot mainly at full frame on Panasonic Lumix S5 (a few cropped shots) HLG color profile. ISO 400-8000 Music from Youtube library
