If you want the best sound in your video, you really do need an external microphone. Many cameras today offer the ability to plug a microphone into them, which you then usually mount from the hotshoe. Not all cameras, however, do. Two cameras, particularly renowned for their vlogging abilities don’t have microphone sockets, which is quite surprising. Those are the Canon G7X II and Sony RX100 V.
Ted Forbes at the Art of Photography has the Sony RX100 V and as one might expect, uses it for vlogging. The problem is that the RX100 V, like pretty much every other camera out there, has awful built in microphones. Ted solves his audio problems with the help of a bracket, a Zoom H1 and a Rode VideoMicro. In this video, Ted explains other setups he tried, and how he arrived at this one.
