Q: 4. To use on the Blackmagic Cinema Pocket 4k, what adapter would be recommended? Metabones? Viltrox? .64? .71?

A: Due to the BMPCC4K having a MFT-sensor with a 2x crop factor, the closest to getting this lens to its original field of view would be the 0.64x, making this approximately a 30mm lens. The 0.71x would give you an approximate focal length/angle of view equivalent to a 34mm. What's recommended would depend on your desired outcome; for example, if you desire crisper detail, the 0.71x would have less compression of detail but offer a narrower view.
