I know that the Blackmagic Production, Pocket, and Pocket 4K use the MFT lens mount but I was just wondering what other companies (besides Blackmagic) out there use the MFT lens mount? My only stipulation is the fact that it has to shoot at least 4K. 60p and RAW are nice but not necessary. I will probably use it mostly in 24p. I like Blackmagic (as I have one) but I would like to know what other companies are out there!
