The Azden SMX-10 DSLR microphone is ideal if you are shooting run and gun with a DSLR camera such as a Canon 5D Mark iii, Canon 7D or a Panasonic GH4 and need better audio than the built in DSLR microphone. Audio is stereo, the microphone measures just about 7" and has a windscreen. The Azden SMX-10 is powered by a AAA battery and uses a mini cable to connect to your camera.
