I should probably clarify - I am in no way considering buying it - I
just find it fascinating watching the Foveon... err... `situation`..
unfold.

It's a pity that the technology just isn't quite there - as it seems to
have great potential, but given that this is a new iteration of the
chip it would be prudent to withhold insults until we see some reviews.
The fact that Polaroid have adopted it - given their chequered history
of late - might just be a sign that they are willing to gamble on
anything...

Unfortunately, the camera also *looks* like one of those horrid
'Megxon'/`DXG` things that get flogged to death on e-bay (or at least
here in Australia they do).. I note those cameras have even more
inflated claims of 5 Mp (from a 2Mp chip!), etc... There's one born
every minute, I guess.

Nice deal, if you have 300 pounds.But I got mine Kodak CX 7300 (99 euro)
Lexar sd 128 MB card (33 euro) orbit charger with 4 nicd sanyo aa batteries
(11 euro) and I heard from more experienced amateurs that it is not
necessary to get crispier photos with more megapixel it is the firmware that
makes for sharp pictures.

According to all accepted definitions of a pixel, the Polaroid x530 is a 1.5
megapixel camera (with three photosites per pixel).

In literature for the Sigma cameras, it's made pretty clear that it's a 3.42
megapixel camera (with three photosites per pixel), even though they try to
claim that this means 10.2 megapixels, everyone knows it's really not. I'm
afraid that the compact camera buyer may be less sophisticated and not
realize the true resolution of the Polaroid x530.

I'd say the Sigma is neither 3.42 nor 10.2 Mpixels as we have come to
perceive the notion of "pixel". Speaking for myself, I wouldn't compare
Foevon pixel with traditional pixel. Just watch the pictures and if you
are happy with them, fine.

If they did like the photos you would never get them to admit it. They have
a bias and they are interested in passing that bias on to others.

That's true, I do have a bias - against junk that doesn't work.

I'm relatively new to this list, but in looking over the archives that
are within the recent past, you seem to have a very strong opinion about
the Foveon chip technology.

Could you explain in terms other than "it's junk" why you don't like it.
I'm speaking about in terms of image quality, not how the technology
is implemented or constructed, or how it is advertised or promoted, etc.

Have you ever worked with, owned, used a camera with a Foveon chip?
What is your area of expertise in digital imaging?

You sound like you have a very solid "opinion" about this technology,
but I'd like to understand beyond your opinion, what it is about this
product that you find so objectionable (again, in terms of image quality).

I have never touched a Sigma camera. I have seen their results though.
It's a 3.42MP camera regardless of how they try to spin the numbers.
Skin tones bear a striking similarity to Homer Simpson. What more do
you need? And they charge a fortune for the thing.

As for my experience, I have been doing photography since 1966 and had
my own portrait studio for 16+ years, photographing hundreds of
weddings and thousands of portraits. I have studied with some of the
best portrait photographers in North America, was one of the first
three CPPs in the State of WA, and earned my AFPh from PPW back about
1990.

I'm curiuos about the skin tone issue. I looked upp the image gallery
for SD9 on dpreview and I couldn't see anything abnormal there.
Maybe my monitor or my eyes are compensating :)

Your monitor and your eyes are fine, the photos speak for themselves.

Yes the do...bleeeech!

But then what do you expect from a 3.42MP toy?

You really don't see the green and magenta stipple in skies and water?

I've not claimed that the camera is perfect and without issues, I just don't
let the idiotic comments of Randall and the like go by without comment which
any subjective person can tell are over the top. No one can accuse me of
being a shill either unless they are being dishonest, they cannot produce
anything I've posted which makes me one. If they try, they might want to
check the posts in which I've commented on other's photos and cameras.

There are times when I get skies that are a bit noisy but not much at all.
I don't see that problem at all in water. Yellow skin tones are a problem
occassionally but easily correctible, I suspect it's a problem with the raw
converter rather than the sensor. Does no one else edit digital images?
Conditions are rarely, if ever, perfect for shooting.

*You're* the idiot for defending this poorly designed and overpriced
piece of junk.

Very likely. In close-ups, the *blue* whites of the eye are the
result.

It's more likely to be a sensor issue, for two reasons that have been
discussed here about a year ago. One reason is the lack of a "color
optimum pre-filter" to correct for the color difference between human
color matching functions and spectral sensor sensitivity. It could
have been corrected, but Foveon/Sigma chose to not include it (perhaps
to save cost, and prevent further loss of sensitivity).
See page 352 (page 4) in the following
http://www.foveon.com/docs/Century.pdf .

Another reason is that when one analyzes the Raw file data (by a
modified DCRAW version), it confirms that color separation is almost
non-existent, and the data has to be significantly processed to
separate the colors. Given that, it is short of a miracle that the
cameras reproduce color as they do, although with some shortcomings.

> Does no one else edit digital images?

Sure, but usually not to correct omissions in the sensor design
(leaving out the color filter).

> Conditions are rarely, if ever, perfect for shooting.

Such is a photographers fait ...
