This is a nice direction for the thread...too many critics will make "near future" SD9 owners reluctant to post images.

Yes. Prime is any lens that has fixed FL. They tend to produce better image quality because the lens is designed for that one focal length.

Is the dark spot in the sky above the distant building in the middle (to the left and straight up from the guy on the sidewalk with the moving briefcase) planet X, a dust spot, or some kind of funky lens shadow?
Other than that, I like what I see in terms of detail.

The irony of someone calling Sigma lenses "proprietary" is quite amusing. Even if Nikon or Canon were the "standard", Sigma mounts can be changed to fit any of them. In this way Sigma is possibly the least proprietary lens line out there (except, arguably, Tamron with their adapters).

Is that Planet X, the Dark Planet, again in the upper right quadrant, or is that what dust looks like?

Here is similar example of the EOS-1D turning bright green ligts into white and red into yellow from photo EOS-1Ds_Skyline_35mm.
Sorry I dont know how to add picture to this email.

P.S. Sigma hase only 12-bit ADCs or up to 72 dB dynamic range, 717,
I believe, hase 16-bit ADCs or up to 92 dB dynamic range, what in
order of magnitude higher.
--No "preproduction" excuses this time. Here is yet another example
of the SD-9 turning bright red lights into pure white from photo
3022 (circled in white). Notice that there seems to be a pretty
steep threshold as some of the lights are still OK (circled in
cyan). Most interesting is the top stoplight that's half blown and
half red.
We've seen this before in the night shots and the Toyota race car
reflections. We could even see it on the imaging-resource 717 vs.
SD-9 train station shots but I couldn't be sure if the original
lights were red or not. Like I suspected, this will NOT be the
ideal camera for taking photos of Christmas lights or fireworks.

Chromatic aberrations don't bug me without hard evidence that it's any worse than what would be expected given the limitations of the lenses used.
The blooming we're seeing in some of these shots does bug me. What do I mean? Areas where bright white regions seem to be causing magenta, blown out looking eruptions around their edges WITHOUT complementary green or blue eruptions.
Other digital SLR sensors will do this occasionally, e.g.,
http://www.pbase.com/image/5122466
This is different from classical CA. I have one lens that is really prone to this kind of effect, even towards the center of the frame - a junk Canon 28-80. My decent lenses don't do this much with my D30 or D60. I'll try to post some examples soon.

Sorry but I do not see it that way, I treat this forum as a place where people with common interest share their info/opinion/news. If you willing so spend the time to post and read the post it show that you are a dedicated photographer, pro or not. So the quality does count. Its not a place where you just post whatever you like. Notice when Phil post stuffs he always tries his best to give us the best quality possible(He readjust the SD9 sample twice and gives explaination of what he did). Posting sample is good, yes, but such is just a way of contributing to the forum. I'm not bashing the photographer in anyway but just amusing that you guys treating him like GOD. He's probably thinking nothing of it. I probably will be the same. When I get my hand on the SD9, you guys will see plenty of my samples(I'm #23 on SS).
Happy shooting.

I hope I did not misread ths but am assuming this post is suggesting that Sigma will remount alens should one change camera bodies. This rumour has appeared in several places on this board and when I first read it I felt better about potentially buying the SD9. However, it is just a rumour. I wrote Sigma as did several others and we each received the sam eor similar response.. Sigma cannot remount a lens
Quote from my Sigma reply:
Dear Sir,
Thank you for your e-mail and inquiry.
The Sigma SA AF mount system is completely different with Nikon or Canon system,
therefore, it is not possible to change mount.

If I misread the point to the thread above me I apologize upfront. Just did not want anyone to believe they can buy a Sigma lens for the SD9 and later change it to fit a Canon/Nikon body!

What in the heck are you talking about? Why are you assuming that there is any relationship between Hirokun (who posted the links) and Asai (who appears to be posting the photos, but not specifically in this forum.)
Phil is a professional reviewer. This is someone sharing his initial impression.
Perhaps sensitivity lessons are in order then.
You certainly have extremely low standards for godhead.
Yes, please come back when you have finally something to contribute other than catty remarks.

Maybe I was confused but I thought "kalahari" had asked if the SA mount could be swapped to the other mounts, but maybe he only asked about changing other mounts to SA. I guess your message clears things up.
Too bad that the Sigma lenses can't be remounted, but hey, the same is true for Nikon, Canon, etc. A common lens mount would be really cool, but i don't think it will ever happen.

OK, folks. Here are some examples from my D60 with two lenses:
28-80 II
24-85
The first is a junk lens. The second is a mid-range lens.
The posts are:
20-80@50mm F5.6
same as above with false color filter enabled
28-80@50mm F8
same as agove with false color filter enabled
24-85@50mm F5.6
same as above with false color filter enabled
24-85@50mm F8
same as above with false color filter enabled
http://www.pbase.com/parr/video_card
Some caveats: These tests were not perfectly scientific for several reasons. I did not use a tripod. I used a flash which varies the power based upon the scene. Small movements could cause big differences in the exposure.
That said, I believe that these are indicative of what I've observed with these lenses through use. Some observations.

- The 28-80II might be a little sharper than my 24-85 at 50mm. I've noticed this in other tests too. 50mm is the sweet spot for the 28-80II.
- Heavily overexposed areas (e.g. the gold contacts on the video card) show evidence of charge leakage in all shots.
- The 28-80II has severe purple fringing at F5.6, whlie the 24-85 does not.
- The purple fringing is mostly gone for both lenses at F8.
- The false color filter does a lot for these images. Many of the chip pins have very weird colors without it.

You're obviously going after this problem with some enthusiasm.
I recall discussions in the past, however, that ended up inconclusive.
Earlier in this thread I suggested that the purple fringing might be due
to near UV (in the secondary spectrum). Are you using a haze filter on
either lens? Do you have a haze filter you can try on one or the other to
see if the purple fringing is reduced? This may be a long shot -- I still
think this problem is probably electronic, but if it could be solved
with a good haze filter, that would be nice to know. Photographers in
earlier days used a yellow filter on their lenses to reduce the effects
of chromatic distortions (with B&W).
Good luck,
Darrell

As it turns out, I keep a UV filter on the 24-85, but not on the 28-80 II. I do this for protective reasons only. Digital cameras have UV filters built in and don't benefit from adding a UV filter. The 28-80II just isn't worth the cost of a good filter.
Anyway, I do have a comparable filter at the right size for the 28-80II (B+W multicoated UV), so I just did a quick test at F5.6. Adding the filter didn't help at all.

I agree with you 100%. Also I am glad the photographer tried to push the camera. How are you supposed to learn about the limitations of a camera without pushing it? If what we see in these pictures causes CMOS meltdown, then we need to look for another technology.
I am also glad to see the post. I have never understood the need for all the personal attacks. I wish people would stick to subject matter at hand instead of resorting to attacks.

Who knows the real truth! Sometimes I wonder if emails get messed up via translation but know Sigma did email a few people including myself that re mounting the lenses was NOT an option. is too bad since that would have made the decision to buy an SD9 a little easier! Least the people buying Nikon mounts can switch from Nikon cameras to Fuji or Kodak. Options are always nice! I hope the SD9 does very well in both sales and in performance and I plan to watch it closely. At same time the newly announced Pentax is also deserving of watching! Tis all fun though and good news is no matter which DSLR we end up with , it won't take long before we realize we are much worse than the camera lol

Ron, try a B&W 420 or a Haze-2A. Most so-called UV filters don't do much of anything in the band that silicon responds to.
