But that won't give the DOF effects of 35mm or the high ISO for candle
lit scenes. The setup in the OP is not over the top compared to shooting
film, and it's still a lot more compact.

DOF effects are completely unrelated to the size of the sensor...
Get the correct lens and you get the correct DOF effect, for any
format.

Nonsense. The size of the negative enters into DOF calculation (as does
the intended final print size).

Yep. Enlargement ratio (negative size to print) is actually the most
important aspect of DOF presentation. I'm surprised that Noonsie
doesdn't know that.

For many small sensors, lenses fast enough to get some of the desired
effects are unavailable, or even physically impossible.

As for high ISO for candle-lit scenes, watch Stanley Kubrick's Barry
Lyndon: shot on "dirty" low iso film, candle lit, 38 years ago. Of
course they used the frankencamera...

Yes, they did. Rather special lenses!

f/0.7 Zeiss designs for NASA (Apollo program) and then further modified.
It's not clear to me if Kubric borrowed/rented/bought/stole the lenses
from NASA or if they were new lenses made for him.
