Like it would take a lot to stomp a Sigma into the dust. For once, you
may have gotten it right.

No surprise there.

It is hard to see a reason for the SD14, but there will be a few
people that will buy it.
Sigma seems to always be about 2 to 3 years behind, if they came out
with the SD14
in 2003 they might have had something, but now who cares?

well, compared to the sd10, it is heaven.  the camera now has more than
one autofocus point and in-camera jpegs!  

anyway, supposedly the sd14 is 'as good as a 10 megapixel bayer
sensor.'  but 10 mpix bayer cameras with more features cost half as
much as the sigma and they can use a wider selection of lenses and
accessories.  

if the camera was $499, it might warrant a second look, but certainly
not at $1600.

Well, the cheapest metal bodied camera right now is the Canon 30D at
around $1100.00 for the body.  $1600 does seem excessive but it's
possible this is intentional.  Remember the idea of creating a demand
for presige?  Price is prestige.  Maybe they rationalized that if they
sold it for $800, they wouldn't sell as large a total $ volume as at
$1600 to Sigma adherents?

Does Sigma have "adherents"? I bought a Sigma lens for my XTi, but only
because it was a lot cheaper than the corresponding Canon lenses and a
colleague at work told me it was a better value. I didn't even know Sigma
made cameras.

Actually they do.  There are those who have joined the Cult of Foveon
and there are others who just like the lenses--contrary to popular
belief, Sigma makes some very good lenses--their big failings have been
quality control and the quality of their reverse engineering of the EOS
mount (the xxxD ain't done 'til the Sigmas won't run), not their optical
design, at least not on the lenses in the higher end of their price
range.

I'm glad to see the retailers finally coming to their senses and stating
the true resolution, not what the marketing people tell them to write.
"B&H: SD14, 4.7 Megapixel, SLR, Digital Camera."

It might sell well against the Olympus E-500, if they could get the
price down to $400 for the body only.

I think they'll be happy with a niche market, they likely didn't bank
on anything beyond that.
No one is going to sell a metal shelled camera for less than $1000
today.

Looks like the SD14 is busting a.s on the 5Ds color, and detail without a
lowpass filter, NO morie seen.
 Only if it was good on Hi ISO.

Fuji's S-5 seems to be the best bet when it comes to a "prosumer"
camera.  The Nikon D200 body, better noise control and compatibility
with all Nikon accessories.  Costs a bit, but WAY less than Canon's 5D
with FAR better lens support.

Stick with the 5D if image quality is your main concern. You also get a
lot better selection of lenses, including lenses that aren't possible on
the Nikon mount. You'll soon forget about the few extra hundred dollars.

My test cam went back today. I have been unable to get an image any way
matching the EOS 5D in sharpness at 12 megapixels. It simply isn't the
same. In fact it's less detailed than a D200/D80/A100 etc 8 megapixel
blown up to 12. Pity because it has great colour and many excellent
features.

$2200 is a fair bit for a "niche" camera, but the users on the Fuji
group on dpreview seem to like it.
I'd love to see this thing tested, if dpreview ever gets around to
it.  Assuming it's "worth" it to them to test it (or the Sigma).

Just remember that Mike Chaney's QImage program is primarily based on
selling you the idea that he knows how to resample (upsize) images
better than anyone else (and I'm not claiming that he's right or wrong).

More precisely, he is one of the few people who will sell you a
program with a gui frontend to various upsizing algorithms. If I spent
a couple of months reading journals, selected the 10 best algorithms I
could find, and wrote a command-line program that upsized better than
his (let's assume that this can be done, and assume further that I
could do it), how much would you pay me for it?

I don't think the problem is getting the hang of anything. But if he
starts out by splitting out the red part of the CFA (which, fairly
obviously, has around 1/4 the total pixels of the total array) and
comparing that to the full image from a non-CFA imager, it occurs to
me that he is setting out to prove a point rather than to investigate
anything.

His arguments are perfectly fine and his conclusions may or may not be
right (I suppose they're not as far wrong as most people here would
immediately think, but have no idea, not having used a non-CFA
camera), but he hardly seems like an impartial observer.

And, of course, he would only be impartial if his conclusions matched the
expected from the Canonista crowd.
I think his comments re looking at the pictorial results instead of the
"numbers" are appropriate, regardless in which "camp" you reside.  Good
advice at any time but usually ignored.

Your irony is misplaced, I am not a "Canonista" (I don't own a Canon
camera and actively dislike the idiotic cheerleading of canon going on
here and elsewhere).

Did you read that link? He starts by comparing the red part o the CFA
(ie 1/4 of the pixels) to the full image of another camera. If you
consider this "looking at the pictorial results" or impartial, well, I
don't see how a meaningful conversation can occur between us.

You also appeared to miss my second paragraph. But never mind, carry
on replying to what you think is being said instead of what is
actually being said.

Your categorization of my comments as irony is interesting and I'm relieved
to see you dislike the cheerleading as well!

Not only did I read it, I took the time to understand it.  Interesting that
you consider his premise of starting comparative commentary from the weak
point of the "normal DSLR" to result in your "biased" view of his comments.
I feel he started out by exposing the weak points of both designs accurately
and furthermore pointed to them photographically.
Conversations are only meaningful when both parties give credit to the
other's agenda-free position.  Given that understanding, you may be right.

Since here is where you pointed out his non-impartiality, perhaps my
understanding of the obvious is better than your statement of whatever it is
you thought you said.

Please explain how

"His arguments are perfectly fine and his conclusions may or may not
be
right (I suppose they're not as far wrong as most people here would
immediately think, but have no idea, not having used a non-CFA
camera), but he hardly seems like an impartial observer."

can be interpreted to mean that I disagree with or dislike his
conclusions. I was pointing out that he quite obviously started by
blatantly throwing out 3/4 of the available pixels in the canon. This
is hardly impartial; did he study colour accuracy in the sigma?
especially as the ISO goes up? Look at fig. 5 in
http://www.foveon.com/files/CIC10_Lyon_Hubel_FINAL.pdf
and tell me how easy it is to separate R, G and B. Or look at the
acrobatics needed to properly convert the sigma files (the R G and B
separation isn't very good so the off-diagonal elements in the colour
matrix are huge). Is the response of each separate channel linear? How
much does it deviate? These things can be worked out from papers put
out by Foveon themselves (with a bit of effort), and they are not very
pretty.

Look, I'd love for Foveon sensors to work, I find the low ISO
photographs excellent in terms of sharpness (but it is partly due to
the fact that they can get away with not having an AA filter because
aliasing is less visually objectionable than in CFA cameras). But they
do have their problems and it is easy to see why they have them (so it
is not just a problem of the particular implementation but something
that really does need more work). He said not a single thing about
these; instead, he talked only about sharpness. That tells me he was
out to make a point, not to test things. It doesn't mean that I will
ignore what he says, just that it rings a warning bell.

Just like all the people here who concentrate on signal/noise ratio to
the complete exclusion of resolution, ergonomics etc, or other
examples I can think of.

I am sure he did this partly on purpose to have fun with the reactions.

the sample images bear this out - the color isn't quite right (i.e. the
yellow skin tones) and there are weird color blotches, particularly as
the iso is increased.

Of course he was out to "have fun with the reactions" and to point out the
obvious in a comparison of AA vs. non-AA captures.  He also pointed out some
glaring firmware shortcomings as well.  However, let's not forget he also
pointed out some obvious shortcomings in the production of the AA filter
equipped 5D's images.
My God he actually had the fortitude to stray into that hallowed ground of
Canon criticism and that, in my opinion and especially in this theatre, is
interesting in itself!!
In my opinion, whether or not the Foveon is ultimately successful will
depend upon whether or not the bodies can be made publicly acceptable (as in
the mass market) before the development funds are exhausted.  No astonishing
news there.

which demonstrates the effect of an anti-alias filter and not the
difference in sensor design.

what he neglected to mention is that the eye can't see lower chroma
resolution very well.  what matters to humans is luminance resolution
(measured with a b/w res chart), and the 5d easily wins there.

true.  and the fact that the sigma is priced at 2-3 times what
competing cameras cost, yet delivers less, does not bode well for its
success.

I think they mainly have to do something about the colours and about
the noise. If they manage to get good consistent colours up to, say,
ISO 1600 (from what I've seen, things currently turn nasty much before
that; it has to do with what I wrote above, I think), and if they
manage to get a bit higher resolution (no matter what he says,
upsampled images from the SD10 I've looked at seem significantly worse
than from my D200; I don't know how different it is from the SD14,
don't forget that we can also sharpen which this guy didn't seem to),
then everything is fine.

I saw some pbase gallery of SD14 images today, very disappointing.
There were lots of ISO 800 images, and there was quite a bit of noise;
not so bad, it was high frequency so probably not disturbing in a
print, and I don't mind high-frequency noise anyway. But the problem
was that it was there at lower ISOs too, even at 100! I assume the
photographer lifted the shadows and that's why, but it's still
unacceptable.

I hope they manage to solve these problems, as an idea it's great
(mainly because you can avoid the AA filter since you don't exacerbate
aliasing/ringing artefacts by colour interpolation) but currently I
personally wouldn't pay so much for this camera. Well, plus I wouldn't
really like to be forced to use only Sigma lenses, and the camera
itself is not all that impressive, but that's another story.

foveon sensors need an anti-alias filter too.  it is just that the
artifacts on a bayer sensor are very noticable and *really* ugly, but
on a foveon sensor, the artifacts get mistaken for additional detail.

every discrete sampling needs a low-pass filter (oversampling also
helps, which is another plus for more luminance sampling locations).

except that the pictorial results are flawed - look at the sample
picture of the ribbon.  the canon image has far less of the ribbon in
focus than the sigma.  out of focus images don't tend to resolve all
that well...

Could this (out of focus effect on the ribbon) be attributed to the Bayer
Blur (color based because of chip design) that seems to be the basis of his
hypothesis?
By the way, the ribbon shot is gone since the update today !!
Interesting.

hmm.. so it is.  i guess he got a lot of flack for that one.

anyway, the focus in the two ribbon images was drastically different.
the canon one had much less depth of field and appeared to be focused
in a different spot than the sigma one was.  he said he used the same
f/stop on both, so this is not too surprising.  he also said he didn't
tweak anything in the raw processing, but the sigma software applies a
healthy dose of sharpening by default.  

his tests do not take into account all the variables between the two
cameras, different sensor sizes and raw workflow.

Looking at the pictorial results, I could hardly agree with him.  Especially
when it seems he used his majik algorithm to improve the Sigma shot, but not
the Canon shot.  All thinks were not equal in that "test."

I think if you give it some serious thought you will find that not only
"thinks", but the "things" in the test were not equal.
Nor were they intended to be!!

he claims that the sd14 is sharper but his raw workflow differs (in
particular, the sharpening), as does the framing (for instance, with
the girl pic).  so the differences he is seeing could be due to any of
a number of reasons.  from looking at his samples, it looks like he is
mistaking aliasing artifacts for real detail.  

here's a blowup of one of his images:

he also tried using the sd-14 at a wedding, and was very dissatisfied:

someone else shot this at iso 800 - you call this good?
<http://www.pbase.com/cgreek/image/75713153/original>

not only is it noisy, but the color blotches are simply horrifying.
those blotches are even visible (but not as dramatic) in the iso 100
blowup from above.

A side issue perhaps, but Mike states:
"Also tried Canon's DPP 2.0 for 5D and several other converters but
Bibble produced the best resolution"

I haven't tried Bibble on 5d images - I use Nikon, and I'm not going to
load a Bibble trial version again just to test it out.
But I did do my own extensive tests on *nef files, and Bibble Pro
produced *by far* the softest tiff or jpeg images of any of the raw
converters that I have tried (RSP and RSE, UFraw, Capture, Capture NX,
SilkyPix, and a few others).  It wasn't a subjective "it looks softer",
but a significant difference.
Does Bibble really work well on Canon raw files?

I think you need to follow the threads from this pro photographer more
closely.  He comes to a different conclusion than what you allude to.    He
sees more resolution in his SD14 prints than he does in his 5D prints.

Of that might just mean that his preparation of 5D files for printing may be
flawed or that his printing system is doing the wrong thing to prepare 5D
files for printing.

Could be, but my point was that the OP was technically taking something out
of context.  The same shooter whose thread he referenced has been more than
pleased with his results from the SD14.

Sure, I was just commenting that I don't think the testing was valid, as
ever show us the prints!!
