Q: shallow DoF. I use 5D3 mainly with f/1.4 primes to obtain a good shallow DoF (I usually don't use wide lenses, so in my case, I'd use Speedbooster only for increasing the "speed").
Now, let say we have two scenario: 1. BMPCC4K + SpeedBooster + f/1.4 EF lens, 2. BMPCC4K + f/0.95 mFT lens. Which of these two options can go closer to the percentage of in-focus/out-of-focus of 5D3 + f/1.4 EF lens? Are the two options equally close?
It depends which speed booster you're using, I have a 0.71x Viltrox which is a 1.35x crop DCI (1.44x UHD). With a 0.64x speed booster it's a 1.22x crop DCI. https://www.metabones.com/article/of/SpeedBooster_for_BMPCC_4K I almost never shoot any shallower than f/2.8. I haven't done the math, but with either speed booster an f/1.2 lens would be close, I'd go with a de-clicked f/0.95 lens to be exact.
