I use the Sony microphone that Tina is using, and it is totally unsuitable for this application. Actually, I own several of them, and every one has now been changed to use the high-sensitivity Primo EM158 omnidirectional capsules.

As shipped from Sony it has two unidirectional (cardioid) microphone inserts inside those wire mesh screens, and each is pointing directly outwards (at 180 degrees). Which gives a sound field that sounds terrible.

As an omni, however, that little mic container works really well... with a sensitivity >20 better than the original Sony which Tina is using.

ps: you can buy Chinese rip-off versions on Ebay which already have omnidirectional capsules, although those capsules are pretty weak by comparison with the EM158. Search for "ECM-DS70P ELECTRET STEREO" and you will find the rip-offs selling at a very low price indeed...

Well, the reviews from real people are coming in on Amazon regarding the Kodak Zi8 and -- I'm disappointed in one thing: THE ONBOARD MICROPHONE RECORDS A HIGH-PITCH WHINE.

(Reviews at bottom of page referenced by above link)

Now leaning toward buying the Aiptek Action HD GVS instead. Maybe.

Amazing isn't it, how manufacturers always manage to put some kind of flaw in an otherwise great device and then act mystified when it's pointed out to them!

I have heard something on some camera footage that sounds like my media player's LCD back light. When recording with it, the recording will whine until the back light goes off (maybe th complete LCD screen).

If you knew what you were doing, you could probably rip it apart and isolate and shield the noise yourself. These things can happen innocently. If you design circuits in isolation to each other, they might appear to work acceptably on the test bench, but when manufactured a deviance in design or components might let the problem slip through, or it might only become evident afterwards.

Does this look similar to the new RCA model?

Well, I was hesitant to order a Zi8...

...but I took the plunge and ordered two (2) of them in spite of the warnings about the high-pitch whine of the onboard microphone.

The reason is I absolutely must have two functional cameras with external microphone inputs for a university project and my budget is extremely tight.

Based on my observations of test video that's been kindly uploaded by other users, I think the external microphone input does work well.

I'll find out first hand soon. I'll use a Rode VideoMic:

I'll also use an Audio-Technica AT835b shotgun microphone.

Wish me luck.
