I know this is somewhat subjective and a function of focus puller's skill, but what focal lengths are usually used with Red Dragons?
I have a Tokina 11-16mm 2.8, Angenieux 16-42mm 2.8, and Schneider Xenon FF primes 2.2 (25, 50, 75, & 100mm). I would think that filming in 6K would allow for cropping in post. In a complicated shot, how wide open do you generally shoot? I think you would need a depth of field of at least 3-4 feet.
