@azonenberg @neil Fuji XE-4, TTArtisan 7.5mm fisheye. Don’t know the aperture because it was pitch black and it’s a manual lens, so not recorded, but probably about f/4. ISO 160, tripod (obviously).
Basically, drop the iso as low as possible, as long as the camera is able to subtract hot pixels, etc (which the Fuji is).
And pray nobody drives past in that 15 minutes, because it’ll wreck it.
