How to update the firmware on a Viltrox EF - M2 - II Speed Booster for use with a Blackmagic Pocket Cinema Camera 4K. Link to the firmware download page viltrox.com/pages/ef-m2
Viltrox has removed the links to firmware downloads. They are all replaced with a link to smartphone apps. Which don't seem to connect to the Speed Booster. Anyone have a solution?
