I assume you meant the clicking sound? Yes, it's the sound of the lens doing a quick hunt for the right focus.

That noise is awful and makes this "enhanced video" (Nikon announcement) almost unusable. Is there an option to turn the sound recording off altogether to not waste filespace on audio which you will have to edit out anyway?
I guess it will be the same on the D7000 then, only that if I remember right that one as an external mike jack?
My conclusion: If good video and fast LV autofocus are important to you on a DSLR, get a Sony.

Is the AF silent on the A55/33? Assuming one uses the onboard mic.

Well,
I was not impressed ( overall impression and not only the AF.. rolling shutter is visible, sound, exposure .. ),
I still think that stills cameras are made for making pictures.
IMO
If you need a P&S video device, use a dedicated video Cam..
It's cheaper and will give you in most cases, a better results .

Thanks Anthony
Great help, very informative video.
Sorry I did not know that there is no mic input on the D3100 (the question is really why not???...Arggghh Nikon, that would have been soo expensive)
Outer microphone would have helped thet
The problem is not just the sound of the lens but the focusing, it really seems to be hunting a lot. Not that smooth focusing what is on a video cam.
The best will be manual focusing, and forget autofocus face detection etc...
But that also means that the cam has to be put on a tripod with some kind of video head etc...
In the video department Canon is still ahead...

I found another test on youtube.
Focusing is loud here as well but not that much
Not as fast as the Sony A55, but not that bad either

That's better. Anthony, have you tried a different lens? There's got to be something wrong. I cannot imagine Nikon releasing the D3100 with such unusable audio. Could you do a test shielding the microphone to see how much of the noise is internal in your case? Could it be that your hand is applifying the noise?

You can still hear it, the big difference is that is uses phase detect, so its a smooth swishy sound.. with CDAF, theres a lot of hunting back and forth, which makes that puttering sound. I think part of it is the sound itself, and another part is the vibration through the body making it to the mic. I bet its not isolated.
Best option is d7000 with outboard, isolated mic.

Keep in mind, the environment I was in was very quiet. The youtube video has a lot of ambient noise.
I've also tried with the 35 f/1.8, 70-300VR with the same results.
Like I mentioned earlier, the video is good the have in a pinch. I could use it to capture that moment in a park, or create a short movie with background music.
But if you're looking to capture your children in their first school play, you might have issues.
There's a very good chance I may return the camera to BB. ONLY because I already have a D40, and I'm very happy with the images. I really wanted the higher MP for my new Canon Pro 9000MKII 13x19 printer. The video was a bonus.
The camera was also a downsize for me. The "other camera" I've been using was a D700. My lower back forced me to downsize. I sold all my FF gear, and now I'm in the market for a lighter, smaller replacement. I thought the D3100 was a good start. I'll also give the D7000 a good look. It seems like a winner.

Yes even for the king of the video DSLR Canon 5DII the outboard mic is a necessity.
Not just the focusing sound but also the sound of your fingers + wind noise etc...

Yes that is true. It is very clear that the focusing sound of a DSLR lens is simply louder than that of a video cam. There are louder and quieter lens focusing methods but it will never be silent. The worst could be the screw driven lenses (D7000 can operate them but no-no for video).
So an outboard mic is unavoidable. but it is better anyway to use it.
it is a shame that the D3100 has no microphone input.
could the 'faster' focusing in this sample could be due to the colour contrast of the lego?

OK, here's another clip taken outside, with lots of ambient noise from passing cars, and enough contrast to assist the AF.

Which lens??? Focusing is really loud.
Would that be the same with all the lenses?
How about Canon would that be the same in the other side as well???
Question if an outboard mic could help that or not? (Probably yes, a lot)
Thanks for the informative videos.

Hope you are not one of those people who drive prices up needlessly for everyone else by exploiting retailers' generous return policies because you can't resist the urge to test every new product which is released. At least you have given back by allowing us to identify the focus noise issue.

Thanks. Still as annoying and unusable. I'd rather focus manually or cut the audio rather than put up with a sound track like that.

naa contrast detect is more accurate.
but yeah sony implementation is very different and should be more responding.

How about the live View? if the lens is as responsive to get the object fast in focus? or it struggles like in D90?
Nice and Thanks! It seems D3100 is capable to hold the focus once the subject is locked. Certainly better than no C-AF. This is a simple single moving object test. A better test is a soccer or hockey game. Or chasing a pet, kid with panning...

No complaints about the live view. It seems much smoother than the D90 was. Of course I could be imagining this, simply because it's a new toy
But overall, I don't feel the live view is a hindrance.
