Some new infos about dp2Q from the touch and try event. + JPEG samples from Yodobashi and MapCamera
9

Thanks to people in Japan. They are sharing infos on Twitter which they got from the touch and try event.

I am summarizing them.

1. dp2Q has a better screen. It's not as good as current Sony's screen, but it is as good as Olympus's screen from a couple years ago.

2. The leather look alike part of the grip was a plastic at the CP+, but it is now a rubber.

3. You can choose the color of the grid line. White or black. DPM has only a black grid line.

4. SIGMA is going to publish new dp2Q Image samples which are taken by Yukio Uchida in Taiwan.

5. Yukio Uchida says "The resolution spec of dp2Q is about 1.3x times to DP2M, but I felt it was about 1.5x". "The contrast and sharpness of DP2M were a bit strong, but dp2Q is natural so it makes the gradation on Chromemode more smooth." "dp2Q's RAW data is easier than DP2M's RAW to edit and try in several ways. DP2M's editing was a walking on the one way path to the best goal." "However, if you like to check the newspaper every day and shoot it, you will prefer the DPM to dpQ."(Maybe he is talking about the sharpness.)

6. Some DPM users claim if you edit the RAW file, it is hard to tell which is the dpQ and DPM, but JPEG shows a huge difference. SIGMA rep said they focused on JPEG as well. The pics in this article are JPEG, which is taken as RAW+JPEG. http://photo.yodobashi.com/sigma/imp/dp2q.html

This is the original size of jpeg sample. http://photo.yodobashi.com/sigma/img/imp/dp2q/08b.jpg

7. After all, the difference of IQ is not so big, but the user experience is a big difference. Easy to use, quick response, and great IQ.

Edit, MapCamera also released new samples of dp2Q. I don't know are they taken by RAW or JPEG. http://news.mapcamera.com/KASYAPA.php?itemid=24737

Thanks for posting. Unfortunately, Google's translation is not very clear, but the colors do seem natural.

thank you for report. from what I understand, they give Q more flexibility and friendly in post-processing. possibility of increasing micro-contrast and sharpness in SPP. what I see as benefit is possibly in B&W rendering is better. my opinion as was before is that this is fine-tuned Merrill or Foveon sensor.

That is a smarter way to explain!

Thanks! Looks good. Glad to heat the samples will be changed.

Low-lilght Waterfall

The full-size low-light waterfall looks very good and very clean.  I increased the brightness to max (150) to see what was behind it.

Brightess 150 in Photoshop 5.5

Okay, but not convinced.

I think that's it; better user experience (responsiveness) while maintaining good IQ.

The downside seems to me, that IQ has changed but it's neither better nor worse. It only seems different ... the resolution might be little higher now, but I didn't see fine color detail so far in any sample. In contrary ... beside the old birds, the linked one from yodobashi is horrible in the shadows. And the six samples from DigitalCamera.jp don't seem to be less hard detailed/sharpened than Merrill samples. I even think, they look harder ... may be because I always tend to use -0.7 sharpness with Merrills, okay.

The ones from MapCamera are downsized. Yet you can see line noise in the ISO 800 image. Less color blotches here, but no fine color detail as well.

Of course, we will have to wait for RAW, since every reviewer chooeses his own development settings ... and the images may actually be better than they got developed from the reviewers.

Are you serious?

Some luminance is maintained, but color seems lost almost everywhere. It's even worse than a Merrill sample. I'm used to decrease chrominance noise reduction in SPP as far as possible, to get color back (and some blotches of course) in the shadows. But few blotches are still better than no color at all ...

Bare in mind that Rick used the JPEG not the RAW to increase the brightness, I would imagine that editing the RAW would yield better results.

I'm aware of that. I wasn't wondering, why Rick didn't improve the JPEG but why he seems satisfied with the result. I think you can see the missing color and the funny blue and green blotches even without brightening the dark parts. So there already is a flaw ... I can only hope we would have gotten better color rendition with different export settings out of raw.

My interest was in showing noise and blotching.

Re: The ISO 800 shot looks good..

I'm very impressed by some the high ISO shots.

3200 - Forget it

Still 800 looks borderline, but very usable!

There's some vertical banding going on.

I thought that when I looked at the link. It is taken at ISO100, but it is hard to tell with the bokeh and that it might have possibly be raining.

Very unlikely, that it is raining drops 100% vertical with fix distances in between. I would also like to say it is line noise ("banding") for sure. And it's not the only image ...

I did see a few vertical brighter thin stripes, if that is what you mean about the vertical banding in some places then I do see them. Rain could be a possibility, I'm just not ruling out the possibility that it is not vertical banding.

Maybe I am not noticing the vertical banding that you both are seeing.

To me this sounds quite allright. That's why I call it line noise instead of banding. Banding is a term matching for quite a lot of effects (e.g. posterisation in color gradients without dithering).

The shot is way underexposed..just look at the histogram and the greens are the most underexposed.  So you wouldn't expect much color.  This is more likely an issue with the exposure of the shot and not the sensor.  I believe it is a credit to the new sensor that when you push this underexposed shot, you don't see the noise and blotching that you get with the M series.

Also, as a further comment, and not related, the black and white images look very good IMHO.
