This is an audio test (not a video test!) of a pro XLR mic vs an inexpensive consumer mic. I've been using the Azden SMX10 for a couple of years with the Panasonic GH2 and have noticed a troublesome level of hiss and room noise. Part of the problem may have been the GH2's preamps, but I suspected the mic as the real culprit.

After upgrading to the GH3, I wanted to upgrade my mic input as well, so I decided to see if a pro mic would make a difference, so I bought a Hosa MIT-156 line matching transformer and an inexpensive Audio Technica pro mic on eBay and plugged them directly into the camera. I then shot a few minutes of video with the AT835, followed by the SMX10. The results pretty much speak for them selves (pun intended).

My first attempt at sound sync between two cameras. Done manually, using the GH2's audio as a scratch track for sync. That part turned out OK, if I do say so myself. Too bad the video isn't as good as the sound sync. This was shot quickly before taking the family out to a basketball game, so please forgive the lighting and focus challenges.

Shot with:
A cam - Panasonic LUMIX GH3 with 14-140 lens
B cam - Panasonic LUMIX GH2 with Olympus 11-22 lens and MA1 adapter

Mics: Audio Technica AT835 and Azden SMX10

1080/30p AVCHD for both cameras, +2/3 stops, so both cameras are overexposed.

VIvid Color on the GH3, Dynamic on the GH2. No color correction, and no makeup on the so-called "talent"
