Did you know that when shooting video, more often than not, audio is more important than the video itself? On this lovely example of one of our rental Canon 5D Mark III ($225/day), we have attached a Sennheiser MKH 416 48 U shotgun microphone, and a Beachtek DXA-SLR PRO professional audio adapter.
The Sennheiser MHK 416 48 U microphone has a supercardioid pattern well suited for studio use and also outdoors. This mic has very low susceptibility to wind and pop noise.
The Beachtek DXA-SLR PRO is a two channel, active XLR adapter with built-it preamps for attaching external mics and other audio gear to any DSLR that has a built-in mic input. Very easy to set-up and use, this unit has exceptionally low noise and wide bandwidth preamps for superb audio. $25/day
*** For aesthetic purposes, I have intentionally omitted the cables that run from the mic and audio adapter into the camera.
