compare different camera systems: for identical DoF + FoV AoV + Shutterspeed

there was a discussion before about why phones seem to take better pictures these days. I am just trying to work out a simple formula to convert settings that my s9 has taken pictures with to settings on my Canon M100

S9 crop factor is 6.1 (1/2.55" sensor)

M100 crop factor is 1.6

Is there a simple calculator somewhere to convert aperture, shutter, ISO from one size sensor to another?

If phone used f1.7, 1/125, ISO 1200, what should I set my camera to for a similar looking picture?

match:

  • FoV AoV (identical)
  • DoF (actual aperture diameter size) = Identical
  • shutterspeeds = Identical (desired freeze action or blur effect)
  • same visual look (adjust different boost ISO effect)

ignore:

  • ignore iso boost (adjust live boost preview to same visual look) = different ISO is normal (expected)
  • ignore pixel size (different; cannot change anyway)
  • ignore f-value brightness (going to be different anyway, in order to match exact same visual dof via identical aperture diameters used)
