Image Stabilization vs Noise

Based on some published information from a review site, IS point and
shoot camera seem to be more noisy than non IS camera. This I'm
blaiming on electrical pickup from the piezo motors used to move
either a lens element or the sensor.

Anyone have any experience or comments on this topic

My immediate reaction is, no, that cannot be. But did the extra noise
disappear when the IS was switched off? If, by noise, you mean image
"grain", I think it extremely unlike that motor interference would be
sufficiently random in nature to look like noise.

It would help if you provided a link to the review
site.

And: Audio noise in movies or video noise in
images or noise you hear from the camera with
your ears? Unclear.

I have three IS cameras and four IS lenses for my
DSLR. None of these types of noise has been an issue.

I would like to read the reviews, too, but I'm guessing the newer IS models
have more megapixles and thus more noise(?).

I Googled it and found some references to acoustic noise with some IS
cameras.

As the other poster said, cranking up the pixel count without increasing the
sensor size will cause more noise.

I'm guessing it's because the p&s IS cameras have "digital" stabilization,
which, in many cases, is merely a bump up for ISO and shutter speed, which,
of course, results in more noise...

Exactly right, as finally concluded in this long thread over the last
two days.

Turn it off, if you can, if you don't need it.

Note too that digital image stabilization (DIS) has neither a
stabilization sensor, nor does any image motion. Just ISO bump up,
which amplifies system noise as well. We finally concluded that calling
this IS was quite misrepresentative.

Optical image stabilization (OIS) has a tilt sensor, and a moving
mirror to shift the image.

Charge motion image stabilization has a tilt sensor, and shifts the
image digitally in the pixels electronically.

Inexpensive consumer cameras just have DIS. No sensor, no piezo motors,
no nothing.

Oh, GAWD.

First most point and shoot cameras with image stabilization have optical
image stabilization just like Canon and Nikon DSLRs. It's only the Fuji
and possibly some other other cheap POS cameras that pretend that they
do by increasing the ISO. Second, optical image stabilization does not
use a "moving mirror", one of the elements in the lens moves, those
elements all being lenses unless its a catadioptric.

The Oly FE-170 I was flummoxed into buying for my daughter for Christmas has
"digital image stabilization," not an expensive camera, at $150, but from a
respected mfr.
I won't argue your other points, (moving mirror?), but some of them move the
sensor, don't they?

My Canons (S3 IS and SD700IS) do it with optical
elements in the lens system .. just as with the
Canon SLR lenses.
