My guess is the autofocus is not the only moving part. The lens aperture could be changing too. Unfortunately, this is not uncommon for such small camcorders. If you cram it all that 'stuff' into on space you are bound to hear motor noise. Remember also that the size of the lens on the HD1000 is enormous when compared to the smaller glass on the Xacti E1. That means the motors need more power to move the elements for focusing and adjust the irisdiaphram (assuming these camcorders have them. I posted two short clips from an E1 and an HD2. Each is about 10 seconds in a silent room. The HD2 also has a larger faster lens than the E1 but it is still not as large as the HD1000's lens:

To getaround thisnoise issueI use an external Sony mic when necessary (i.e. more quiet shoots). Everything has its trade offs. My old Sony VX2000 had no noise issues but of course that is a MUCH LARGER camcorder and a pain to lug around.



Hope that helps,



Joe

Hi,



You should instantly notice that the HD2 is MUCH MUCH louder. Don't forget that even in manual focus mode the shutter is still operating to give you the fps (frames per second) exposure. I just uploaded a third clip of the very loud HD2 in Manual Focus mode.

I just ordered the HD1000 so I can't post a comparison clip yet but I will do so before the end of this week.

Regards,

Joe:-)

What kind von Sony mic do you use? I am also searching for a small external mic for the HD 1000.

The normal noise of my Xacti HD 1000 is louder then your exsamples (perhaps only the sensitivity of the internal mic is higher). Zooming motor or fokusing, yes you hear it.Also wenn manaul Fokus, the "basic noise" is highor only loud? You can make this comparion soon.

I wrote some replies in the "New Sanyo Xacti HD1000 Hybrid"-Forum.

Thanks, good mic (120€ in europe). To big.

Here is an audio sample from my HD1000, distance 1 yard from the cam, one sentence (german), only voice recording, no focus noise, only other internal noise (like a fan or sounds like"sparks", when you put your ear to the cam-body).

For this type of audiorecording (interview,etc.) I think you need an external mic. But it shoud not be very big.

Hi,

That does not soung good. It almost sounds like radio static or a VERY poor signal to noise ratio. I am uploading two mp3 files of audio from both an HD2 and an E1 using the internal mic at a distance of 1 yard.

You can clearly hear something in the background of the HD2, like a motor spinning. It could be the shutter mechanism...then again maybe not.
