So on the surface it seems like Sony wins this battle with the FX3’s dual base ISO of 800 and 12,800 ISO. Canon on the other hand has a dual base ISO of 800 and 6400. The difference of 6400 and 12,800 ISO is one stop, and while that could make a big difference 1 stop is probably not that big of a deal…until it is.

if you had to sum up the difference between the two similar looking mics it would come down to these two features:

The Wireless Go II can record audio as well as transmit audio, and works with up to two microphones.

The Wireless ME can record up to 3 microphones, but has no onboard recording option.
