Ah yes. I love how my 50mm lens with its 39 degree horizontal field of view perfectly replicates what my human eye sees with its literal 180 degree horizontal field of view.
You can always spot the midwits who espouse that dumb shit about how 50mm closely approximates what the eye sees.
Hey fuckwits, ALL LENSES SEE WHAT THE EYE SEES. "Normal" requires viewing distance.
50mm lenses were the standard because a double gauss formula is among the simplest and cheapest of all lenses to make, and making it close to the diagonal of the film is the simplest variety of double gauss to make.
