I made this breakdown for forum users who've asked which shots came from which camera. You can download the 1080p version for a better analysis.
Red Scarlet was A-cam. BMPCC/5D Mark III were for Glidecam 4000HD shots & low-light. GoPro Hero 3 Black Edition was for aerials.
I received the Black Magic Pocket Cinema Camera later on in production, which was a shame because I would have used it more. In low-light, it smoked the Scarlet. Compared to the 5D3, it had cleaner blacks @ ISO 1600 and much better dynamic range because of the base ISO of 800. Also, the 5D3 gradually loses dynamic range as you push past 100-200 ISO.
We also mounted the BMPCC to the Scarlet for a number of scenes where time and money were of the essence. Here's the rig + a comparison still:
Pocket was the wide so that the S16 aesthetic wasn't as noticeable paired with a S35 close-up. The footage matched up extremely well.
The way these cameras matched up in post goes to show that it really is your story that counts. While we were fortunate enough to have the options, one of these cameras could have been more than sufficient (that being said, the "RedMagic" rig really did save us some time, which saved us money).
