Interesting response from Panasonic regarding image quality-
This is very interesting. It actually jives with my impression that the Panasonic/Leica noise looks different to me than most digicam noise. It's monochromatic, almost like film grain and relatively acceptable to my eyes. Most digican noise (especially high ISO noise) consist of color noise that is very distracting to me. Combine a low-light shot with red, green, and other color noise and the result is not good.
I don't know if I buy their explanation, but anyways...

Thank you for your e-mail. Our technical staff has advised that information
has appeared on various web sites regarding the image quality of the DMC-LC5
still photos when viewed at 100% size on a computer screen.
The concern centres around the fact that some parts of the picture
occasionally contain what appears to be noise, making it appear "posterized"
or "solarized". This is evidenced by a granular appearance on the surface
of a photo being shown on a computer monitor, occurring occasionally in
areas with mild colour transitions, mild contours, or three-dimensional
attributes.
This granular appearance is similar to what would appear on larger prints
from analog film. This information is very important for the expression of
depth and surface character --> the three-dimensional appearance of a
printed photo. This three-dimensional quality is not typically
characteristic of most Digital Still Cameras. The reason for this is that
most Digital Camera manufacturers optimize their picture quality for
two-dimensional viewing on a computer screen. Thus, they look good on the
computer screen, but may lose some of their depth and surface detail when
printed. The Lumix picture, on the otherhand, is optimized for print
quality and attempts to recreate the photographic characteristics of film,
and as such, contains this information that may look strange on a computer
screen, but contributes to its excellent print quality. We feel that it is
much more important to focus on print quality, rather than on-screen
quality, since people want to print high quality photos from their Camera.
The on-screen photo is usually used for viewing and e-mailing, where high
picture quality is not the primary concern, and is not even achievable on a
monitor.
Please be confident that these "artifacts" that occasionally appear on the
computer screen are not noise or compression artifacts, and do not show up
in the printed photo. They are an important part of the image data,
responsible for mild colour and contour changes that provide the printed
image with its excellent detail and three-dimensional characteristics. And
even when this phenomenon occurs on-screen, the printed photos look great.
In addition, please keep in mind that a number of these on-line reviews are
done by people who have never actually used the cameras and are based on
images they have downloaded over the net, often a degraded image quality.
Serious photographers do not take these reviews seriously since they feel
that photo quality should only be judged on photos, not on computer
monitors. We encourage you to view a printed photo, or better yet, one that
has been developed, before judging image quality based on what you see on a
computer screen. Many of our retail dealers can show you printed photos
from our Camera.
We hope the above information is helpful to you.
Sincerely,
Customer Care Centre
Panasonic Canada Inc.
