Re: Some new SD1 samples!!!

the petriied was nice nbut don't have the sd14 or dp1 quality at base size. i mean it doesnt seem so different from a normal 16 million apsc sensor with a good macro lens in front. It has the same caractheristic of an sd14 file upszied 2,5 , in my opinio uspizing it to 30 million pixel will be ridicolous.

Having reexmined the shots I've found three sharp images:
1. the 70mm macro shot of the petrified wood
2. the B&W car bumper taken with the 50f1.4 at f5.6
3. the landscape taken with the 30mm f1.4 (center only)

conclusion: the SD1 shines only when using the best fixed focal length lenses at their best aperture. Would also really love to see some shots taken at iso 100 using a tripod with mirror up to eliminate any camera shake. And as someone mentioned earlier, using Leica R glass would really help.

Re: Some new SD1 samples!!!

The final firmware and processing better improve.

My guess is they haven't optimized the processing yet. This CAN be improved with software and firmware, which we have seen sigma do in the past.

At the moment, these images only look good when downsized 50%. Effectively the same as using VPS low-mode.

In fact, you could even think of the SD1 as a super-sharp 4MP camera with bigger pixels than the SD14.

Re: not pixel-sharp

This is a 181% crop of the petrified forest shot. Does anyone see any "Bayer-ish" here. Maybe a direct comparison with a D7000 or 7D would be helpful.

Click Original to view full size.

To me it looks like Foveon all the way down.

If this was made with firmware 0.91 - what's fw 1.00 going to look like?

Re: not pixel-sharp

This was one of the best shots in the bunch (to me). I also liked this one:

Both seem to show great detail, and looking at it at pixel level, it looks like the foveon images I like so much, not at all like a bayer image.

Re: not pixel-sharp

And it is ISO200!
I definitely want to see the ISO100 with FW ver.1.0.

Being very fond of rocks, this is a lovely crop!

I agree that most of the other shots don't seem remarkable.... some other hill slopes and rock shots are....kind of what we get running around the US Southwest.. Rick does better.

Re: Some new SD1 samples!!!

Yowch - I can't see one of the wider ones which wouldn't be as good or better with a canon 550D and a Tamron 18-270 superzoom .. that is not 15Mp's worth of SD14/15 pixels , a Nikon D2X in RAW with the same lenses would toast that .

Re: Some new SD1 samples!!!

I'm not impressed so far considering it is a $7K camera.

Re: Some new SD1 samples!!!

In addition to the petrified wood, I looked closely at the last landscape of the painted desert vista. The detail is sure there, lots of detail. Now just add some Foveon punch/pop whatever you wish to call it... that's somewhat lacking.

A lot probably does depend upon post processing. "Artistic" merit... will come from the photographer LOL.

Lenses? I've thought all along best primes would probably be needed for the SD1. I was hoping (snif) to use my 50mm EX, 105mm EX; and to buy a 85mm EX.

Re: comparison essay link?

Hi Jim, the Japanese photo essay made me think of your great photo essay from the SW trek with Rick. Do you have a link? Might be interesting for non-Sigma users to see what the current cameras produced on your shoot.

Does it look like the 8-16mm has a centering issue?

There's one shot where the left side is visibly softer than the right.

It doesn't do any good to have a high resolution sensor if the lenses don't keep up.

Re: not pixel-sharp

this is one(among a few) with weird patterns in the sky....very weird...lokk at the left side...

I could be a much better photographer if i was out there taking pictures, instead of talking here at dpreview....

Re: Some new SD1 samples!!!

completely agree.

in my opinion many here don't even know what a good bayerish sensor can do, and not only in daylight but in any condition, while the foveon seem just a daylight studio sensor.

these files don't have the per pixel sharpness of my sd14, and for this is completely wrong to believe these are 45 million pixel file, but not even 30.

maybe the superb uprez capability are linked to the number of pixel. packing a sensor with 15 million could lower this capability.

in my opinion these files uprez can be similar to a nikon d3x or sony a900, year s behind any medium format.

Re: Enlarge the photo

IMO, these photos in the article are too small to show the merit of X3. Right click on the image and open the image in new window. These are pretty impressive shots.

Re: Some new SD1 samples!!!

We have to wait and see. Maybe the release firmware and software will do the trick, or even a patch.

At the moment these images need to be downsized to 50% in order to match the SD15 pixel quality.

In my opinion, a big part of the problem is the noise reduction algorithm being used. Hope it can be improved or disabled.

...WE SHALL SOON SEE!

Re: Enlarge the photo

i opened them and i m not impressed. any bayerish camera with a good glass can do that. thinking this camera can reach 45 million is cheating, even at 28 is cheating. this camera is on par just with the actual 24 mm full frame.
in my opinion all the photo show a lot of sharpening and artifacts due to this.

i need more sample to a complete evaluation but i'm thinking the foveon magic end up at 4 million pixel.

Re: Some new SD1 samples!!!

in my opinion the fact that they have packed the same sensor with 4 times the number of pixel has something to do with IQ at pixel level.

wile sd14 uprez pretty good, i think like 2- 2,5 times compared to a bayer sensor, these files uprez no more than 1,5 at the moment.

Well, I believe that there may be some bayer camera can do this, but not that much. When considering open at 100% to view the image, the number will be reducing to single number. Just a few photos from FF+great lens satisfy me with the same result under full image view.

Just wait and see for the final firmware.
Nevertheless, I agree that SD1 should not cost this much. A terrible price tag.

Re: Enlarge the photo

well i see a lot of artifacts and a lot of oversharpening, not really great fine details.

i have sd14 and i know the per pixel sharpness at 4 million pixel. is much much better than this.

personally considering all the problems linked to foeveoon, and that seems also in the sd1, i ll take my k5 nigh and day, simply beacuase i can shoot everywhere and in everry ligh tcondition.
in myy opinion thi camera is overpriced even at 2000 dollar.

Well, I don't think these tester will change the setting too much. I tend to believe that they may shoot with default settings mostly and adjust a little bit. It seems like Sigma is facing a new challenge to take care of this new baby chips.
