I confess not to have understood all of your post, Ko. Fe., but I will elaborate about why I thought it might be a digital mindset. With digital, one may shoot at 1.4, let's say, more easily and under more circumstances than with film where one is stuck with a single ISO and perhaps 1/1000s as the fastest shutter speed. That was my thinking regarding the digital remark.
Sorry, my ESL is even more complicated than my way of thinking.
On one of my birthday party, person who knows me over decade, made tost about how I will tell something and he needs to think for sometime to get it.
😀
If you want to keep it on gear level, not creativity, to me it is dead simple.
If I want f1.5 lens on film body I want it on non-cloth shutter camera.
In my case it is TTL metering Bessa. I could make exactly the same as on digital via vND filter, but I like my f1.5 with bw film. So, I just slap x4 or x2 contrast filter.
But
🙂 in real photography here it is, f1.5 lens, wide open, no TTL, cloth shutters on sunny days and two of them are with primitive FED-2 with 1/500 as the fastest one:
Films were 50, 100 and 400. Sunny f1.5 at all of them.
Film or digital, it doesn't matter, once you learn about filters use. It is not difficult, just screw, unscrew; digital, film is the same.
