This is a quick comparison of Sony's XLR-K3M Adapter Kit with both the included ECM-XM1 shotgun mic and a Sennheiser MKH-416 shotgun mic, along with the compact camera-mounted ECM-B1M shotgun mic. Both take advantage of the A7R IV digital audio interface through the hot shoe.

For this comparison, both Sony units are set to digital, and the audio levels are set to auto. For off-camera testing, the Sony and Sennheiser shotguns are placed between 1 and 1.5 feet (0.3 and 0.5 meters) from me. For on-camera testing, distances include 6 feet (1.8 meters) and 3 feet (0.91 meters).

I didn't do any audio processing of any kind for this video apart from cloning single channel audio to both right and left channels. Otherwise, audio is straight out of the camera.
