    Re: Sigma DP2 Quattro Shots

    What I have seen so far from the Quattro is excellent, but also seems to be comparable to what a Sony A7r with one of the e-mount primes produces. The Merrill is different enough to keep it around. The Quattro does not get my money although it can make for an "Aston with Quattro inside" .

    Quentin,

    what is your take on the 39MP JPEGs from camera? I really don't like to use the Sigma raw converter.

    Uwe,

    Not tried one as yet - as I rarely use jpegs out of camera, although I hear they are much better with the Quattro.

    Been setting up the Quattro for use with Nodal Ninja pano head. Not as easy as with the Merrill due to the odd shape.

    Will shoot a jpeg or two tomorrow

    Probably, but I have reduced them now in any event. Much less apparent in the original Tiff.

    Uwe,

    From Raw, or in-camera jpeg? I tried an in-camera S-Hi jpeg and it looked a bit oversharpened. This sample does not look over sharpened.

    From Raw

    If you want to use in camera S-Hi you need to sharpening to -10 :-). But I gave up any JPEGs in camera today because I got bad banding in skies.

    Conclusion: Be patient with Photo Pro :-)

    Re: Sigma DP2 Quattro Shots

    It sounds to me like many of you are trying really hard to convince yourselves that the Quattro is better than the Merrill.

    Most of this is subjective as is any Art form.

    I will be receiving my Quattro loaner tomorrow and I will find out for myself.

    These "how many Angels can dance on the head of a pin ?" arguments get tedious.

    Try the camera for yourself and then decide if it suits you better than a comparable Merrill.

    Good shooting.

    I actually like the rendering of the Merrill over the Quattro much more. I see the Q kind of X-TRANS flat rendering if I dare say
    I find the Q more 2-D over the Merrill that shows incredible 3-D rendering.
    Colors apart, they seem quite correct with the Q. The M is a bit off. I though find color fidelity less important unless you shoot documentary. B&W images are really off true colors, but well accepted
    (May I say that colors perceived on the WWW are screwed up anyhow. Monitors not calibrated and what do we have?)

    Anyways... Who likes the one over the other is a taste category question not to be objective answered. Photography aught to be art at the end of the day.

    The information gathered in this thread is pretty informative and a good guide to the potential buyer.

    Wonder what will be shown around when the Q's are matured?

    Re: Sigma DP2 Quattro Shots

    Looking at these comparisons: https://www.flickr.com/photos/preben...57645396604688

    The landscapes (Q1, M1, Q2, M2) were taken handheld and at different times. The Quattro looks better, but the Merrill images don't look representative of what I can get out of my Merrill.

    M3 is better than Q3.

    The flower images are out of focus, and don't tell me anything.

    M6 is better than Q6.

    M7 is much, much, better than Q7.

    Just when I think there's a test that finally shows the Quattro is "better", I see an image from the Merrill that blows me away once again.

    I think the Quattro can only get better though. I hope so. Maybe I'll pick up a DP1Q.

    Re: Sigma DP2 Quattro Shots

    When you look at comparison shots done by someone else, then unless they are tripod mounted raw files, you are judging the photographer and his personal choices as much as the camera. I think what we all wanted was an improved Merrill, but what we have been given is a different camera, and none of us have enough experience with it yet. I will continue to give my Q a thorough work out over the next few days and weeks before I reach a definitive conclusion.

    In the meantime, lets see some more shots taken with the Q

    You probably right. Europe will be open sea then?

    Look at Fuji. Even though they spit out a new camera every second day, they find it worth to satisfy owners of cameras solving bugs even on few generations before the newest newest most fantastic.
    I like them for doing that But it shows how poorly matured many first gen cameras are.
    I blame the shareholders for it. Employees performance bonuses and that sort of quantity oriented values.

    I start to like the Quattro. All handheld by the way.

    Actually my main issue is Photo Pro. Good developers would make it more usable and at least 10x faster.

    Re: Sigma DP2 Quattro Shots

    This is kinda hard to say but those image have a bit of a "step away from Foveon, step in towards Bayer" kinda feel to them. That's not bad quality, but it's just not quite what the Foveon used to be.

    That said- try shooting the Quattro in low res mode- that should give you a true X3 color capture.

    As for SPP being made faster- agree with you 300% I found out looking at an app on the Mac that it doesn't use the GPU.

    Re: Sigma DP2 Quattro Shots

    This looks like junk and is junk. But it is part of some art work.



    Here is a art work:




    This art actually tells a story. The river Leine snakes through Hannover (double n in German). Each of the three cubes contains junk recovered from the Leine in a well defined quite small stretch and at a certain year. There are plaques that list all of it.

    Motion blur handheld. The 39MP rendering shows even very minor shake:


    This may look ok at this size but it shows motion blur. Yes, the DP2Q deserves a tripod :-)

    Well, Sigma doesn't have that excuse. Family-owned and family-run company. They do have to feed their employees tho, so some stuff gets pushed out the door a bit early.

    Looks good, but any better than resizing normal size (19 mp?) files up to 39 mp in photo zoom or perfect resize?

    New sensor, same lens = better bokeh? Really? The Quattro files look comparable to the Sony A7r ones. Nice with lots of resolution and good color but lacking the Foveon bite.

    In these examples, the sharpness of the quattro is as good as merrill.
    Only small details are contrasted with merrill. But I think these example, including landscapes, large numbers of small contrasting details merrill, remove the modeling and depth to photos.

    nice photos Ustein.

    Re: Sigma DP2 Quattro Shots

    An option worth trying is to turn "off" all noise reduction and sharpening (-2), export as a 16 bit TIFF S-HI (so a 39mp file) then add a little sharpening to taste. This gives a very respectable imitation of a circa 40mp MF image, with excellent pixel level detail and sharpness.

    so here is a crop from a S-HI version of the train line shot, moderately sharpened using smart sharpen in Photoshop:

    >This gives a very respectable imitation of a circa 40mp MF image, with excellent pixel level detail and sharpness.

    I second this. Too bad there is no 39MP mode for the DP2M.

    Re: Sigma DP2 Quattro Shots

    Thank you Quentin and Uwe for posting these images.

    While it appears that the resolution is good and fine detail capture stellar... Quentin's last 100% crop appears to be shot through a very weak soft focus filter. There is still a thin veil of diffusion in this image. I've never seen this on any other camera... and I think that for certain applications it could be very desirable.

    Surprising that the resolution can be so good in-spite of this. I think this shows the potential of the sensor with more mature software development...

    I think that because of this slight diffusion the yet to be released DP3Q will be an even better portrait camera as well as being better suited for certain things like floral photography and portraiture.

    In the event Sigma improves Sigma Photo Pro, it might be useful for those who appreciate this slight diffusion to save the current copy of SPP as Sigma may do away with this haze in future releases. Personally I like it for the aforementioned applications.

    Lawrence,

    Some of the diffusion effect is because the image was shot through glass and the crop is a distance away on a slightly hazy day.

    I did two tests with photozoom. Accentuation worked with photoshop.



    The same version accentuated.


    Click on the thumbnail.
    Then the image.

    Spp, seems to me as good as photozoom for interpolations.
    My examples are just more contrasted and accentuated.

    Re: Sigma DP2 Quattro Shots

    Its fine, Uwe. I use several sharpening and upscaling tools, none of which I have with me on my office Laptop (they are on my main processing PC back at home). Just shows how good the files can be, particularly S-HI, and where most of the post processing is done outside of SPP.
