The issue is the difference in “sensor” size. The “crop factor” of the rPi camera is 5.5 so a 50mm lens provides an angle of view equivalent to a 275mm lens for 35mm film.

To get down into “normal” lens equivalent would require something like 8mm. A fisheye would probably be ok because the center tends to be relatively less distorted. But if there are 8mm rectilinear lenses for 35mm film cameras you probably can’t find one and maybe not afford one...Its price would buy a lot of film.

I mean there are digital sensors that retrofit film cameras. Products for Hasselblad 500 series and Mamiya RB have been around since the early days of digital. They have always been less than $100k and still are today.

Anyway if you want to use an old film camera, just buy some film and have a go. They are incredible mechanical devices and a pleasure in the hand and produce that film look naturally.

Heh, with the amount of cropping, you don't need a rectilinear fisheye!
