The new Sony FX6 seems to be the perfect combination of a DSLR camera and the bigger brother Sony FX9. The camera is well equipped for timecode synchronization with file timecode, which basically every editing software can read and process. The FX6 has a dedicated timecode BNC input on the right back, which can also be switched to Output.
