Now you can check it vs D60 and others in building picture.

Just one word: moirè
As in, there is NO moirè in that shot, where as in his 1Ds sample it's clearly evident:

Overall, I was little disappointed with these shots. That 20-40 zoom lens seems to be popular, but I'm not sure that it's making the camera look good.

The 20-40 on the Sigma? Or on the 1Ds ? I haven't read (or perhaps I overlooked) what Yamada was using.

Well, I can't read Japanese, but below the last picture in the SD9 batch, it says 20-40mm F2.8.
I'm assuming that this is the lens they used for all of the shots.
For their 1Ds shots, it appears that they used Canon's 16-35L F2.8 lens.
It's hard to make good ultrawide zooms. Canon's 16-35L has 3 aspherical elements, 2 fluorite elements, costs $1400, and it can still be a bit soft. I don't know much about the Sigma 20-40mm zoom, but I don't have high expectations. The CA this lens produced on the latest Chasseur D'images shots was pretty bad.
The moire on the 1Ds shot is interesting. Some people over in the Canon forum (and in the new Kodak FAQ) have been saying that moire isn't a problem with higher resolution sensors. My answer to this has been that if it's a problem with a low resolution sensor, it can be guaranteed to be a problem with a higher resolution sensor from a further distance.
Of course, you can also get moire with a foveon sensor. It's just that it's much more difficult to get that kind of red/blue pattern. The Foveon sensor could still get B&W moire.

I wonder is Sigma sending the test camera out with these lenses, or are photographers able to try on their own lenses (I'm assuming the latter... and if so, perhaps this is all that Yamada had at the time?)
This is the lens we're talking about?
http://www.sigmaphoto.com/Html/pages/20_40_ex.htm
The site at Photozone rates it as follows:
Sigma AF 2.8 20-40mm EX DG --- 3.46 (2) = good
http://www.photozone.de/2Equipment/easytxt.htm
I didn't see it at the Photodo site yet.
Indeed....
Exactly!
Now, that will be interesting to see, and I'm waiting to examine some shots like that eventually.

Chasseur D'images were shot with the Sigma AF 2.8-4 17-35mm EX (HSM) not the Sigma AF 2.8 20-40mm EX DG. The 20-40mm lens has a higher rating.

The few lenses that have been used are certainly a poor match for the SD9. The 50mm prime looked good sharpness wise, but these zoom lenses are rather soft when matched with the SD9.
The 50mm has a rating of 4.2 on photodo and 4.65 on photozone
The 20mm - 40mm zoom 3.46 on photozone
The 17mm-35mm zoom 3.1 on photodo and 3.02 on photozone

Here is the English wording...
---------------------------------------------------------------------
" Sigma * SD9 "
Beta Edition photograph taken on the spot data
The FOVEON X3 was loaded from sigma
Digital single-lens reflex " SD9 " was announced formally.
You can obtain each data of the RGB in 1 pixel,
As the model which loads the new generation CMOS image pickup element of attention,
The picture quality is about greatly to become matter of concern.
This time, was only 1 day, but
It was possible to photograph with the beta edition model of the same machine.
Because Web release of that data becomes rescindment,
Is small amount, but we would like to publish those which are taken picture on the spot with the same machine.
The data which is published here is the JPEG file, but
As for the knitting machine because of the RAW data private machine, in order to play back with general-purpose environment,
One time, it is necessary to develop with the thawing software of attachment.
This time with the private software, it develops picture setting automatically.
That data the same software is used, those which are retained with the JPEG data of quality 10 are released.
Furthermore, because this data is in a state where contour emphasis processing and the like does not catch,
To consider this point, administering the アンシャープマスク and the like according to need,
The capability should have been known probably.
In addition, this beta edition body is early ones relatively,
Until in the picture quality aspect it becomes product edition, you call the schedule which still improves.
Because of that, to the last development midway, you call capability at present time.

not very useful though...

Look at the picture of the ship, near the top of the mast. Three big spots. (2 on the right, 1 on the left) (There are alaso about 3-4 more other spots distributed across the photo.) Whats going on here?
I thought the SD9 had a built in protector to keep dust off of the sensor. Was this due to the use of an extremely high f-stop?...

This is ufair! Samples seposed to be taken with fixfocal lenses, othervise dubm people will blame sensor for lens abberations.

The pictures are taken on different days, so lighting, etc. are different. I download both samples at ISO100.
If you scale the D60 image down the the SD9 image sice and compare them up close they are very similar in sharpness. Including some sharpending artifacts around som of the letterin the banners.
The D60 seems to have less noise. The SD9 has no color moire on the side of the building.
The sky in the D60 is very grey, but I assume that was the sky color on that day, so it makes color compairision difficult.

More importantly try upsampling the SD9 image then comparing...impressive eh?
Upsampled SD9 vs D60 is much like Upsampled D60 vs 1DS.
Sure there is not moire in SD9 sample but in terms of image detail I don't see much improvement

There's a quality to some of the SD9 pics that I am having difficulty putting my finger on--it reminds me abit of old b&w movies that have been colorized. There also seems to be some very subtle color bleed, as though the camera is exaggerating radiosity.
