A80 movie noise

[JonS]

I Have just bought an a80 and it has an irritating
continuous noise on the movie playback which ruins
the otherwise clear sound
I have previously tried an a70 and there is no noise on the movie from this
The sample movie on the review at dcresource doesnt
seem to have any interference which is what i assume it is
Any body else have this problem. Should I change it
Also the screen is obviously lower res than the a70
which is a shame but i can live with that

I would say the background buzz is about the same between my 70 and 80. Whether you notice it or not depends on the sound levels at record time. When ambient sound is low there seems to be some sort of auto gain that winds itself right up and leeds to the buzz.
I find the 80 screen much easier to see than the 70's - but both are inadequate - I would like a much larger one! The ability to rotate and tilt the 80's screen makes taking difficult shots such as non flash inside public buildings (churches etc) using my bean bag so much easier and more civilised it more than makes up for the lack of size. In fact the only time I really want a bigger screen is doing panoramics.

Did not notice the "hissing" noise until read this topic. Yes, there is a very small noise in the back, but as soon other sound you dont notice it. It as a "reasonnable" clear sound for a digital still cam.

Last summer borrowed my brother Finepix 3800, and the video quality was even a bit less than my new A80.

I bought the A80 and found the sound in movie playback has a soft high frequency 'whine'
in playback. This noise does not appear in the sound memo mode. The sample movies I
took in-store had alot of ambient noise which I assume either masked or cancelled this
noise. The retailer exchanged the camera explaining it as a feedback defect. The camera
that I was given as a replacement does the same thing. The noise is not apparent, or is
softer, when the soundtrack has foreground noise or alot of ambient noise. The sound
is most apparent when a movie is taken in a quiet indoor setting without any intentional
soundtrack added. Also, the sound is less apparent when movies are played back on my
PC (rather than on the camera). Since I purchased this camera to use as a still-shot camera
I consider the movie mode as a bonus, though I find I am using it fairly often. If I'm serious
about taking movies perhaps I should be investing in a camcorder, and accept the A80's
movie-mode limitations? Otherwise I am really satisfied with the A80.

I experience the same annoying sound on my Canon A80. It turns out that that the noise isn't introduced within the circuitry, but is an actual sound picked up by the microphone. If one listens really carefully, one can actually hear this sound (put the lens near your ear), when the camera is in 'record'-mode. The sound dissappears when the camera is in playback mode, which is why there is no noise in sound memos.

My guess is that one of the image processing chips generates the noise, but I have no clue as to whether there is a simple fix for this problem!

I know what you mean. I have both cameras and they both seem to have autogain on recorded sound. In a quietish environment you get a sort of electronic buzz. I get the same sort of noise on my videocamera - so you can't win! (Except perhaps by using an extension mike!)
I extract the sound using cooledit and fix it that way. Cooledit has neat noise removal features. I then re-import the sound to the video using - I think it called videosoft - I'm not at that PC! But I'm sure most video software allows you to import sound.
The only problem I have left is that I can't seem to get any format I save in to re-play on the camera.
