SD9 sample pictures from Japan

[Erik Magnuson]

I have to agree with SFJP. The resize/compression on these
pictures is too great to make any judgement on anything, except
that the camera is out and working.

Say what? If you click on the second image link you will get a full size, Q96 2:2 sampling image (which is about 6:1 compression).

This is slightly more compression than a typical "fine mode" JPEG from a modern camera, but less compression than typical for "normal mode".

Does anyone else think that the out-of-focus areas on 00291 (vines
on fence closup) look really strange and ugly? This is the 1st shot
we've seen with a large amount of out-of-focus detail. Is it bad
lens "bokeh", CA, processing, or sensor (or a synergistic
combination of all 4).

At least the shadow noise looks really good on this ISO 200 shot.

At 22m FL and f/4.0, using a 20-40mm 2.8-32 wide angle lens, you have some DOF in play. One would also suspect f/4.0 being one of the poor settings for sharpness. But I do wonder about the upper left corner. Is it the camera, the lens, or motion such as handshake/wind? My guess is this lens just isnt best designed for this setting.

Missed the boat. Zoom in on the boat you will see it there also.

There is alot of CA.. I'm glad that I ordered primes so far.

I agree lots of CA. I hope Phil has a review of the lenses as well
as the camera.

About the only thing I would conclude from these images is that they were taken by an amateur photographer. Let's wait for the camera to get into the hands of some experienced photographers.

I am not using a calibrated monitor at this time, so can not say about the noise, but I like the dynamic range. I will have to see how I like them when I get home.

I have the downloaded the full size image 232 (1,4 MB) and see no

What strucks me in this image is the great dynamic that apparently
the processor can accomodate as the shadows are detailed and the
highlights not blown out and the resolution is huge.

Look at the lamp. (But it all has to do with the lens (I think..
According to Karl it also has to do with the sensor and it’s
layers..) I really would like Phil to do a real lens comparison
test)

All those images have really bad CA, but the colours are beautiful!

I agree...

I am a real novice in these discussions, but it is obvious that the lamp
is covered with bright purple spots (CA), if you really zero in on
it.

If one wanted a textbook example of what CA looks like, that lamp
would be it, I would guess.

I hope the problem is the lens.

Maybe we are going to see now why the Sigma lenses have always
cost less ?

I'm looking at the leaf picture, and the amount of the detail in the shadows is pretty darn good. - just adjusted the curves to open up shadows, and there's so much extra to see....

Can you post a link to a cropped section showing this? TIA

Don't really understand what the photographer has got to do with the 00232 shot. It is crisp and well exposed, and it really shows incredible detail on the telephone lines that go into the distance. It also has an incredible dynamic range: if you lighten the shadow area on the right in Photoshop there is much detail to be seen. There is of course some CA but I can't see any banding at all. Overall, I think it is a great testament to what the camera can do – and it can do a great deal.

Attached are links to a few crops that show "problems". possible dust on sensor (or is it birds flying); ca on leaves; star-filter type images on the water, and a funny blue(?) pattern.

Anyone explain the blue pattern in sd92.crop2 or the water patterns?

Sigma started deliverling SD9 from Oct.27.
Some first owners are started uploading SD9 pictures on the web.
Here you can see one of those samples.
Sorry, I'm not photographer of these pictures.

Agreed. I really liked this one too.

Here is the cropped version of the leaves photo:

The noise is there, but it's usable (IMHO)

It appears to me that the blue pattern in 2.crop2.jpg is lens flare; the result of multiple internal reflections of the sun after it enters the lens off-angle. Just look at the position of the blue bands in relation to the entire scene illumination and I think it becomes obvious that the sun's reflection is the cause.

lens flare, and birds...IMHO

You are right about the lamp -- good eyes. But I believe this is sensor blooming, not chromatic abberation. The purple fringing on bright areas is very common in cheap cameras and typically isn't seen much with the better cameras. However, even a D60 with L lens isn't immune to it in some circumstances.

For a more textbook example of chromatic abberation, look at the shadow of the light pole on the wall. See the green fringe on the left and the purple one on the right? That's CA. You can see it even more in the upper left of the image,w ehre some of the branches have green trails to the left of them that extend quite a few pixels. Even the leaf shot shows a purple fringe on some shadows near the left of the image.

But whatever. As usual the pictures look very nice, but have quite a bit of noise in the shadows and a lot of chromatic abberation. I can't wait until we get a review.

Coud the images look better if a "lense hood" was used to "protect" from "unwanted sun/light" (sorry for bad english), see this lense image to understand what I mean

Sorry about that, Erik -- this computer doesn't have Japanese character sets installed, and I didn't find out what the second line of random ASCII characters meant until after I posted that.

Even with the full-size samples, though, these are .JPG files. Still not enough to make decisions on, except perhaps that a polarizing filter would be a good buy if you get this camera.

I have to agree with SFJP. The resize/compression on these

I'm pretty sure these were taken with the 20-40 zoom, a lens that, IIRC, produced pretty high amounts of CA in the Chasseur D'Imanges images.

Here's hoping it's not the sensor, but I fear you might be right.

Yeah, a lens hood would help the flare -- that's what it's used for: to cur off any stray light hitting the lens surface. Extremely wide angle lenses (like this 20-40) are very prone to flare.

It appears to me that the blue pattern in 2.crop2.jpg is lens
flare; the result of multiple internal reflections of the sun after
it enters the lens off-angle. Just look at the position of the blue
bands in relation to the entire scene illumination and I think it
