Re: An overwhelming reason to move back to Film...

Well we used equivalence back then too.
Not for depth of field (that I remember...) but certainly a 75mm on a 645 was compared to a 50mm on 135 and so was an 80mm from a 6x6 as well as a 100mm (105mm) from a 6x7.
The same for wide and tele lenses .
So a 400mm on 6x7 was a 4x magnification like a 200mm on 135.
Nothing new under the sun.
