    Sigma DP2 Quattro samples have been posted

    Can't see any RAW files, but some jpgs have been posted here - Sample gallery | dp Quattro | Cameras | SIGMA GLOBAL VISION

    Let the analysis begin

    Interesting, the EXIF from the samples shows they were taken on 31st March.
    Shows DP2 Quattro of course.
    The output program is Photoshop CS5.

    No wonder, it's the same bird and sample picutre as leaked some weeks ago. ^^

    Yep, a RAW out of a more recent production Quattro would be nice. Nature, no studio with f/13. I think these samples are too old and were made for presentation-PDFs (as stated and once leaked in the xitek-forums) ... not for a showcase.

    Even if they turned off noise reduction, the red/green-blotches are no less present than in Merrill samples ...

    That's what I noticed as well.
    Looking forward to the SPP update and Quattro raw files.

    I would have expected the color rendition to be worse rather than better because less data is being used to reconstruct it.

    There is more than just pure resolution to creating a special sort of image quality.

    It takes terrific micro-contrast and excellent color rendition.

    The whole being greater than just the sum of it's parts.

    I expect the new DPQ1 to be better than it's predecessor but mainly because of the new and improved lens.

    waiting for more images in RAW format.

    Red/Green blotches -> No quattro for me.
    The red/green thing was the main problem for me with my dp2 Merrill. Now there is absolutely no reason to upgrade. (only thing to consider is a dp1 q, if the lens is better)

    Looks promising, but the subject matter is too weird to reach any conclusions. And if shot in March, must be early firmware.

    Yeah, I very much agree, the site samples tell me little over an above the Merrill.

    This page is a bit buried - Key Feature of SIGMA dp2 Quattro?SIGMA CORPORATION

    An interesting overexposure function incorporated into the Quattro. I wonder if this could be applied to a Merrill firmware?

    This is of course a 'nice to have' thing. An auto variable gradient preset for inboard JPEG processing.

    I do not know about others and how they will shoot this camera. To me the obvious thing is to shoot RAW.
    None of all the cameras I've owned through the digital ages had any satisfying RAW to JPEG conversion inside.

    I'm a regular 43 shooter and have always dreamed to own a somewhat compact quality pixel hi-rez camera for art work and large prints. I've been close to purchase the RX1R even knowing that this camera would limit my photography to 35 mm only. That kept me reluctant to jump upwards for the purpose of image quality gain.
    The new Pentax 645Z would indeed cover my needs for hi-rez, but let me down on its bulk realities. It's a no go.

    The DPQ's might fulfill my dreams. I sincerely hope they do.

    Wonder who will be the first to do an in depth review?

    I'd never expect the DPQ's would be like an E-M1 i.e. That would likely be too much to ask from the maker.
    A little less would also do ;-)
    There are actually only two or three things about this camera I would demand.

    - Precise auto focus w. focus peaking
    - Better files vs. the old models
    - Better UI for both the camera and the processing SW

    I now already there are numerous features I don't get and this new generation is all about IQ.

    Yes. I'll pass on DPQ, I will not review it. The upcoming SD (September ??) might worth a review.

    I heard from several that the upgrade of the DP1 is the most appreciated.
    But I hope certainly it regards the whole DPQ family.

    At this moment no one of us is able to elaborate much more. It will have to wait until we have the DP2Q in hand.

    The commercial review sites will likely be the first ones to pass on their impressions, but let the first actual pixel level sample images talk their language, then there's much more to discuss.

    I am sure that Diglloyd will test the cameras thoroughly and show their worth. They have a soft spot for the existing DP's already.

    Re: Sigma DP2 Quattro samples have been posted

    I stumbled over the shutter speed given. 1/2000 - 30 sec.
    I understand this spec is at tad unspecified in detail for the DPQs'. I assume it will be more or less be the same shutter speed gradation as the present DP's shows?

    How did you DP owners come around freezing a moving object in harsh daylight maintaining the wished DOF?
    How did you come around achieving full DOF control and eventual isolating an object by blurring the background for still photos in harsh daylight?

    Have you overcome this issue just by clamping on a ND filter?

    It seems Sigma does not have a built in ND filter?

    I am not a big fan of filters since they all degrade IQ one way or another. I am neither fond of fumbling with filters. It slows you down the wrong way.

    That clearly explains the need of a second camera system which actually is my case anyhow. Who would throw out an EM1 and replace it with a 3 x DPQ?
    I was afraid the DPQs would not show improvements on the shutter speed side. It is of course almost self explaining as they would have to provide new lens designs for all three of them. IMO SIGMA really should have redesigned their lenses with faster leave shutters making the cameras more versatile. At *least* they could have built in a true two stop ND filter a la Fuji X100.

    Nah.. I can argue my self to death, it will not change anything ;-)

    more samples here.

    looking good, but at 100%, it certain looks like there is some "guessing" going-on, just doesn't look as realistic as merrill generation DP.

    @ UHDR

    The images under the lake scene is so overexposed that it's not worth processing. To my book such shots should end up in the garbage bin. Those images are drowned in flare.
    Would have been more informative if Sigma had shown better examples showing highlight clipping in an image that was still worth to save.
    To their credit I would maybe say that they show courage to use such poor images and try to demonstrate how their in camera processor deals with things vs Pro Photo SW? But again, there's not much evidence yet to evaluate the IQ from the DP2Q. Neither if the Photo Pro handles the RAW fast and well for super prints.

    fast: NO
    well: Photo Pro is the best raw converter, because its the only one^^

    Sigma Camera is a world by its own; as I said above: the only reason to get a Sigma Camera is image quality, and the larger the print, the better.
    I have here 60x90 cm prints, (24x36 inch I think) where you can see details from the trees at horizon.

    very strange. when i posted the link, it was to another page with shots of birds in studio. the whole page was in japanese..... i guess they only want to share that within japan...

    EDIT: hmm.... now the first link is to the birds... im confused....

    Your link points at this site Key Feature of SIGMA dp2 Quattro?SIGMA CORPORATION where I see the crops of a DP2Q and D800 shot.
    Underneath there's an overexposed lake scene which is post processed. Underneath that is some horrible overexposed and flared shot that is sought corrected.

    Wow, what a long chat over at DPR.
    Hard to judge those images. In camera processed and who knows what we are looking at?
    It is beyond doubt big OOC JPEG files.

    You can do just as well as that w a Merrill.

    Maybe not. It is hard to tell. I do not have a reference shot to see.

    Foveon ownership is a new kettle of fish for me. I've shot film the most of my life with MF cameras. My first digital camera was a 5D. Then after years a 6D and now EM1.
    Should the DPQ's disappoint, I am planing to buy the Pentax 645Z. Sounds contradictory? Not at all. I wish to make large super prints where the goal is to cram each and every pixel down on paper. The EM1 offer very rich 30 x 40 cm and a tad above prints. At larger sizes I feel the prints starts to wash out.

    I have made stunning 24 x 36 prints w the Merrill.

    I suspect the Quattro can do the same just not better.

    How do you get the software to work? I was only able to view pics on the LCD of the DP3. I was never able to export any photographs. That was disappointing because the Foveon tech is unique. I know SPP has a reputation, but not even being able to export a photo really sucks! You really need at least 3 or 4 batteries too.

    It was maybe a mistake? Read somewhere it is usable for DPQ too. But it could be wrongly quoted.

    I even saw it is usable with older Non-Merrill-DPs. But honestly, I pretty much doubt the quality is good. May help in sunlight though.

    Would be interesting to send live view to a tablet PC ... wouldn't be great as well, but since it's quite a lot bigger, focussing and judging in fix setups at home might be more pleasant.

    Sure you would see the live view spread on a larger surface, should that keep luminance and contrast high.
    Brings me back to encourage Sigma to develop a hi-rez EVF. Should be every man's need for a mirrorless compact camera.
    It is annoying to see the scene and be unable to frame and record it correctly.

    DPs have a display on the backside but it doesnt give you working live view, this is a point to fix.

    Are you saying the camera out of box is unable to shoot an image without the OVF which is optional?

    I think you two disagree what live view is. One wants live view without any delay and flaws, even with augmented helps, the other one in a way just wants to see most of the image he would have seen through a viewfinder.

    I agree it's not excellent live view, but I think it is. And the aperture should be displayed, as well as shutter time and some other things ...
