One of the advantages of buying a Canon XF305 or XF105 is the ability to sync timecode between cameras. Synchronised timecode can make editing multi camera shoots a lot easier.
However, someone asked me a few weeks ago if it was possible to sync a Sony with a Canon. In theory there is no reason why you can't, because all the manufacturers use SMPTE timecode. But, I wanted to check...and the answer is yes you can.
I've put together a video to show you how to sync a Canon XF305 with a Sony EX3. But, it would work between any two cameras that generate or recognise SMPTE timecode.
