Great news, I may have to start saving for a isco optimized kit of these. The graded footage is a massive improvement, definitely very deliverance-ey. I have an obsession with films from this era(badlands, the graduate, mean streets etc), they were the peak aesthetically in my eyes.
My current attempts to reproduce this look are shooting hacked low contrast gh2, russian glass, isco 36, filmconvert for grain/filmstock. Definitely getting there, but I prefer the image produced by my KOWA over the isco, unfortunately it is pretty un-usable in real shooting conditions for obvious reasons. Some DSO primes might be just the ticket as it would push the bokeh to 2+.
