I have the black magic pocket 4k. The lens i have on it is the panny -12-35. I also have from when I used the original BMCC the sigma 17-50 f2.8 and the Tokina 11-16 2.8 with a novoflex adapter. I'm a director not a DP - and I've heard rumblings about the panny lens. My question is would you folks sell the panny lens and get a metabones adapter for the sigma and i guess a dummy mount for the tokina - it being a nikon lens. I'd appreciate any feedback. Thanks
