Before to panic I have to say that the audio test you can hear on top has been boosted to display the issue. In any normal recording condition you will not notice the issue at all! So this is just for “audio-peepers”.

Suggestionofmotion posted that video on top to show the background audio issue on the GH4:

It’s common knowledge that camera preamps are not the highest quality to begin with. The best practice is to set the in-camera audio gain as low as possible to keep the camera from introducing noise.
Now instead of just noise, we also have a buzz to contend with in the GH4. Just like noise, the buzz is always there regardless of gain level.
At the same time, like noise, if you set the gain as low as possible and feed the camera a strong audio signal, the buzz is buried pretty well.

The good news is 1) In no real word recording condition you will notice that and 2) Panasonic is already working to fix this (Source: Facebook). So unlike Suggestionofmotion I do not see that as a serious issue. TheDingo at DVXuserforum answered to that video test:

When I first heard about this audio buzz issue I was a bit worried about the audio quality of the GH4, but the more I hear about it, I am becoming convinced this is people listening to the actual noise-floor of the camera, which is something that would NEVER happen if you have all your audio ducks in a row.

So don’t worry guys!

Its all about finding ways to tripod mount micro4/3 lenses which I have been working on for some time, its particularly relevant to people shooting with the GH3 and GH4 with battery grip. I am also working on a Metabones Speadbooster tripod collar that also will work with the GH4 and grip.”

Philip: “I ordered the GH4 on Tuesday, April 29, 2014 at B&H in the USA and had it in my hands on Friday, May 2, 2014. Here are two initial “camera test” videos that I shot within moments of getting this fun camera: http://youtu.be/xGFX4MltQVI http://vimeo.com/93919825
I will follow up with a more in-depth review at http://www.pluckey.com in the near future.“

Nauticam (Click here) announced the new underwater housing for the E-m10. These are the key features:

	Signature Nauticam Port Locking System: The iconic red locking lever is right at home on the NA-EM10, making lens/port changes quick, easy and secure.
	Vacuum System: The integrated vacuum check and leak detection system adds extra assurance of watertight integrity. Use it without an optional vacuum valve and it serves as a audible/visual water ingress detector. Add the vacuum valve, and get watertight integrity indication via a color-coded LED light.
	Locking Rotary Latch: Locking rotary latches are easy to use and secure.
	Fingertip Control: Fingertip control for all key shooting controls, including shutter release, focus lock, both command dials, and video start/stop. All of the controls are easy to operate, even with gloves on.
	LCD or EVF – Your Choice: The switch means either the LCD or EVF can be used and the shooter can instantly switch between them – underwater!
	EVF Viewfinder Options: For shooters wanting to take the ultimate advantage of the exceptional EVF in the E-M10, the renowned 180º Enhanced Viewfinder or the excellent 45º Enhanced Viewfinder are available. It is easy to change these viewfinders and no tools are required.
	M16 Accessory Bulkhead: For Vacuum Valve or an Electrical Bulkhead (or both using the offset vacuum valve).

Michael: “I have been testing the Oly E-M1, Fuji X-T1, and now the Lumix GH4 to decide which I want as my alternative system to my 1Dx birding set-up. After my testing with the other 2, after my first test shoot with the GH4, I have decided that the Gh4 meets my needs the best. Image quality, while not nearly as good as the Fuji, is more than sufficient for my need when I will be shooting this camera. I have lots of experience with the GH3, but was not happy with the IQ. The GH4 (based on this one shoot so far) seems to have a smoother grain pattern, that makes all of the difference for me. And I love the UI and ergonomics of the GH3/4 over the others. Here is ny first shoot gallery with a full range of ISOs. I edited the RAW files to look like GH3 files in the meta-data so that Lightroom would read them. LR adjustments are limited to tone and clarity. Default sharpening on all of them and no NR except for the final shot that has Luminance=20. Here is the gallery…
