    Re: Sigma DP0 Quattro shots

    Here is another from my short holiday on the south coast of England last week. The weather was pretty appalling most of the time and so the photographs are a bit miserable.

    I like what I'm seeing, even if it's miserable weather. It's what we live with and have to work with in Blighted. Capturing the mood without ending up with a flat, grey image is very difficult.

    We're off to France tomorrow for a quick road trip down to Cahors and then the Carcassonne area. Taking the DP0Q (plus my A7s for any indoor/low light pics) and I'm sneaking into the glove box my DP3M as I can't bring my self to leave that behind.

    Two architecture pictures, trying out polarizer and 1000x ND filter on the Quattro.
    30s and 15s exposure.

    Re: Sigma DP0 Quattro shots

    I am afraid I have taken advantage of Amazon's 30-day return capability to send back my DP0Q.

    The highlights problem reported elsewhere for Quattro sensors was the deciding factor. I found it really difficult to get around. I did try using Lee Seven5 filters with good results. Sharpness of the lens is not disputed. It is sharper than my CV Ultron 21. But the sensor lets it down for me.

    I am not trying to put anyone off purchasing the camera just reporting my experience. As I do mostly landscape-type photography, reproduction of sky is paramount. If the truth be known I should only working with MF film but I can't lug cameras like the Hasselblad or similar around town with me any more.

    I also have to add that I found the sensor noisy even at base iso, especially pulling out shadow detail. I've never found that with my Merrill-sensor cameras.

    I doubt if anyone from Sigma will read this but seriously, what a wasted investment. Sigma camera owners are all gagging for a CSC with an evf. I don't care if it take 30 seconds to save a photograph. I don't care if I can only use it up to iso400 (although I have had fine results up to iso800 with my DP2M). What I want is a single body with a Merrill sensor and 3-4 interchangeable lenses, a 21, 35, 50 and 90.

    Come on Sigma - what is so difficult about that?

    Re: Sigma DP0 Quattro shots

    I think the main problem is that it takes a great deal of investment to build such a system. Sigma are a (relatively) small, family owned lens maker that dabbles with cameras. They lose money on making their cameras in a way that more conventional companies wouldn't/couldn't tolerate. If they were to "do a fuji" and build an extensive ILC system from scratch, they would likely go bust. It's probably unlikely that you'll see such a thing from Sigma, ever, IMO. But you never know, they may surprise me and whether in the end it turns out to be a foolish pipedream or inspired business vision, they deserve a lot of credit for being wiling to bring Foveon to market when no one else would.

    Oh, I totally agree. I've always admired their products. The Merrill line is unique. When I was a Nikon shooter I owned several Sigma lenses and they were fantastic quality (and value). I was thinking in terms of interchangeable MF systems like the Fuji and Mamiya systems where there were only a limited line of lenses. You didn't need more because of the IQ of medium format film. The Merrills are very similar which is why I suggested a system with a limited range of lenses. It is the opportunity cost of the Quattro line which is saddening.

    Re: Sigma DP0 Quattro shots

    It's a nice idea and perhaps one that a company like Sony would have deep enough pockets to fund.

    But Sigma are a smallish company building cameras with mainly in-house technology and it shows in their products. For example, the inefficient file sizes from the 3 layer sensor and the huge amount of processing that seems to be required even before the raw gets written to card put big demands on the camera processor, and Sigma don't have those highly specialised, super fast processors of the likes of Digic, Bionz and Expeed at their disposal - they cost too much to develop for a production run of a few tens of thousands of cameras, hence the very slow performance.

    Similarly, Sigma lack cutting edge versions of technologies that other brands take for granted (AF, stabilisation, EVFs). They make excellent optics and solidly built cameras but with the developement budgets they have, I can't see them (working alone) mastering all the various state of the art tech and packaging it in one camera like your suggestion. To me, Sigma seem destined to make nicely screwed together but relatively primitive bodies that offer the mimimum functionality required to make a Foveon sensor work and that's it. Niche product only for a small group of fans who love what they do, not state of the art class leading cameras. In some ways it's a great shame that Foveon doesn't get the chance to be show cased in state of the art bodies; on the other hand the big companies chose to stay away from Foveon so it's only by the grace of quirky Sigma that we have the option at all...

    Hulyss - I would take half of what you have on offer, even a tenth as long as the EVF - which incidentally I agree should be a clip on giving you flexibility to use either an EVF or an optical finder - is developed and as long as I can have one body and 3-4 lenses, one of which needs to be equivalent to 21mm. I don't even need fast lenses. I'll use a tripod or as they are leaf shutters I can shoot them down to 1/30th with ease. And it must be the Merrill sensor. Please!

    Some might say that poooor Sigma corporation can't make it but I say Sigma corporation CAN make it, around 70% of it. No need to be a rocket scientist to see, in this speculation, that 70% of it is largely possible within a year of work for any kind of electromechanical engineer. Just to make a prototype.

    For sure, a new processor is needed. The EVF is completely possible and the money is here !! Kill this damn SA mount, kill the SD camera line and you'll save money, for sure.

    The lenses already exist on the DP. Put a stiff mount on them and power it with the body : You have your First compact LF interchangeable lenses. This is what I call a buzz. Make some bigger ones like f1.2 primes and your ok. here we speak for an APS-C model.

    For FF... SIGMA know they need to do one. They even know they are obliged to do one.

    There is one basic rule, outside pixel world, that many photographers seems to ignore or denies: "The less the enlargement the better the picture".

    FF is the way, even with less pixels than Merrill, picture will be better.

    Even Kasuto Yamaki liked my idea. Have a look in the past, January 2014:

    Re: Sigma DP0 Quattro shots

    Funny really, I have been wanting a way to sometimes make my Merrill pictures look more like my Fuji X-Trans ... Iridient has a 'Foveon Soft Look' Option, which I like because with SPP sometimes they can look too harsh.

    I have also been wanting a way to make my X-Trans images look a bit more Foveon-like because sometimes they are too soft.

    Maybe, for me, a Quattro would be a good compromise?

    You got it. It is SPP the problem and not the sensor. The problem always been in the signal interpretation rather than in the hardware. But, if the sensor is up-scaled, some of those problems would vanish even with poor SPP.

    I'm not Xtrans fan, got the XT1 and all the big glasses ... far away from what can be done with foveon and normal bayer. Xtrans was/is a handicap rather than an evolution. Fuji did FAR better back in the day of the S3/S5 pro. PPl who used them know what I mean. An S5 pro still have better DR at base ISO than a A7Rii... With this hype and PR attitude, for me, Fuji is like a sister enterprise of Sony; nothing more.

    Of course I can backup what I say because I still have numerous RAF done with the touit (not that good lenses...) and other holy trinity lenses. Also on this forum, I seen some early evangelists "I thrown my ff gear and now I'm shooting only XT-1" disappearing like magic

    With time and observation you see how much ppl are unstable.

    Maybe, for me, a Quattro would be a good compromise?
    The best compromise, Imho, is patience. It is also the ability to not rush buying the latest "goody" and trying to spot the cult device, like the D700 and other real good devices out-there (the D810 is good but... it is not something as cool as the D700 was in his time) . The Merrill is cult device. All the Canon devices are cult also. Lenses, cameras ... very good stuff.

    Yes, sorry for the deviation. I just want to tell you that the Quattro is FAR better than the XT-1 for any kind of landscape/architecture shoot (if you bracket). I can, if you want, give you RAF of XT-1 + 12mm Touit combo... you'll see that money do not bring performance

    Re: Sigma DP0 Quattro shots

    I still have a DP2Q and DP1Q. Also, of course, the Merrills.

    I'd buy another foveon based camera - even the Quattro perversion of it - if (a) the highlight clipping issue is resolved; (b) lower noise floor at base and up to 400 ISO and (c) full frame, with about 50% more pixels than the Quattro (that would be the equivalent of 60 bayer pixels).

    I'm perfectly happy with a 3 prime interchangeable lens solution, or even, at a pinch, a new generation of fixed lens cameras with superb optics like the Merrills or the DP0Q have.

    No one was a bigger fan of the Merrills than I was, and no one more disappointed by the issues with the Quattros. I have to believe Sigma can, and will, do better.

    You probably know that SPP over-sharpens X3F files at "zero" sharpening. Recently, I did some "slant-edge" testing on my SD1M comparing some lenses. The results for my sharpest lens confirmed the over-sharpening. For my camera/lens combination a just over neutral setting for sharpness is -1.0. Others over on DPR use -1.8 or even -2.0 and sharpen to taste elsewhere.

    Then there is the effect of down-sampling. If you do that, your image gets sharpened more by which I mean that frequencies that were not aliased but were close to Nyquist will be aliased by normal down-sampling algorithms.

    For this reason I normally shoot the SD1M in low-resolution raw 2336x1568px (shock, horror).

    I have also been wanting a way to make my X-Trans images look a bit more Foveon-like because sometimes they are too soft.
    If you have RawTherapee, their LR de-convolution sharpening plus their micro-contrast can make scenes look pretty gritty. Over on DPR's Sigma Forum, @scottelly offered a "Merrillized" X100(?) image amid a totally unwarranted storm of derision, but some of the efforts there were pretty good. Mine was best, of course

    Maybe, for me, a Quattro would be a good compromise?

    As has already been said, Quattro comes with it's own baggage; quite a step to get more film-like images unless you have exhausted all other possibilities . . .

    Re: Sigma DP0 Quattro shots

    Ted's suggestion about turning down sharpening in SPP is a good one. I use -0.8 but even lower settings are justifiable. Another suggestion: reduce colour noise reduction. I don't know why, but this setting doesn't just reduce colour noise, it also enhances that gritty micro-contrast the Merrill is renowned for - in fact, it kind of creates it.

    Re: Sigma DP0 Quattro shots

    I received my DP0 Q last Friday. A few first shots from the Swiss mountains.

    Re: Sigma DP0 Quattro shots

    I've spent most of the day sorting out my photo library and in particular looking for items I can put into my stock photo account. Eventually, I got back to the captures from the DP0Q I owned for a few weeks. I reproduce them here for anyone interested in seeing more output from the camera.

    One thing which did improve the results was to go straight from SPP6.3 to jpeg. My usual process with Sigma cameras is to use SPP to convert to TIFF, then I import into Lightroom and do any further PP there or if necessary in Photoshop. I have to say that I think going straight from SPP to jpeg may actually improve the results. I don't know if anyone else just uses SPP as a RAW and final processor in this way.

    I freely admit this is a weird collection of photos, so I am not making any claims for my skill and indeed maybe that is where my dissatisfaction with the DP0Q stems. Perhaps my skills are not up to using the camera to its best ability.

    All of these were taken in a place called Hayling Island which is on the south coast of England and is a real island which can only be accessed from the mainland via a bridge. It is stuck a little in a time warp and it also was a location for the constructions of some of the Mulberry Harbour sections used during D-Day (the large concrete constructions below).

    I paid about $900 for an excellent 21mm equiv. lens to which a quirky body with an outstanding sensor was attached. Oh, I almost forgot the lcd EVF and a spare battery was in the package as well. Quite a bargain when considering the IQ this combo can produce.

    Re: Sigma DP0 Quattro shots

    Thanks Louis - they look great to me - you should get another DP0Q!. I rarely bother with TIFF as they clutter up my hard drive! For my DP2Q I am finding that the selected colour mode in SPP makes a big difference on default sharpness. And is it just me or are the reds from these cameras (thinking of the phone box here) on some sort of drug trip?

    Lee, I may indeed do that as and when they fall further in price. My mistake was paying too much for the one from Amazon. They have fallen by roughly £170 since then and unfortunately I think that after Xmas they will fall further as merchants realise no one really wants them (except a select few!).

    I noticed the over-saturated reds, as well. That to me is all part of the Sigma look - almost like Velvia in a way.

    Amazon had one bundled with the LVF-01 for £760 a couple of weeks ago but their prices seem to fluctuate - it's over £800 now. I got my DP2Q + LVF-01 + lens hood for just £600 used but in perfect condition. Just for once I think I got a bargain.

    I wouldn't be surprised to see some sort of cashback scheme from Sigma soon.

    In my opinion, Quattro reds are broken with SPP. One solution to avoid over saturated, noisy reds is to use the portrait color mode. This also keeps the general noise under control.
    "Imaging resource" also measured a "default saturation" of 112% percent for the DP2Q, while especially reds are "pumped" even much more.
    "Dark red is pumped quite a bit, while purples and dark blues are boosted moderately."
    If i can't handle the reds in my images, i sometimes use a Kalpanika (X3F-tools) conversion and "repair" the reds with it, as it seems much more natural in its rendering.

    That is a bargain. Especially as the LVF can be used on any DP Quattro camera - which lowers the cost of owning a DP0Q even more. I must admit I have set up a search on ebay for a s/h DP0Q. I wonder if Sigma disease is treatable?

    Personally, if I could be bothered I would use the hue/saturation controls in Lightroom to balance the reds.

    It is a matter of taste but to me this is the Sigma look.

    Not sure if i can agree to that. What is "the Sigma look"?
    We've seen such different results from every Sigma camera, from the SD9 to SD14, SD15 and SD1, or DP1/2 to DP Merrill and DP Quattro. We had over saturated blues, muted blues, we had green
    color casts, we had reds turning pink, now we have noisy Quattro-reds...
    The only "Sigma look" that i recognize across all models is their pixel sharpness and lack of color moiré.

    Re: Sigma DP0 Quattro shots

    I haven't seen this advertised widely but in the UK, Sigma are offering £150 discount on any Quattro from Black Friday to the end of today (Cyber Monday, LOL) if purchased through an authorised Sigma Camera Centre.

    Park Cameras currently have the DP0Q for £599, I assume this has the discount already applied as they were previously £749 ...

    Yes, I saw that. Predictably the price is going to fall.

    I am going to wait for boxing day and see if Amazon have some going really cheap.

    Very nice colors. Is it only a panorama or is it a "HDR"-panorama? I think the Quattro (and you) handled this high contrast scene very well.

    Welcome, Vadim. I think you'll find an interested audience for your work with Sigma cameras here.

    It's pure (non-HDR) panorama. .X3F -> .TIF(16bit) ->AutoPano Giga -> Adobe Camera RAW -> Photoshop -> JPEGMini

    Sorrento, Mornington Peninsula, Australia. Not the greatest composition but the colours in the sea were vivid. And the sea was cold but didn't stop us having a swim.

    Cold morning in Brailes, Warwickshire. Nice stand of poplar trees lit up by the morning sun. Very watery and misty sky. 21:9 selected in camera to give an Xpan feel.

    Cyclamen. I cropped foreground out as I focussed too far back in the scene. I need to re shoot at a higher iso and much smaller aperture. Hopefully, we'll get a sunny day before they go over.

    Hi Ladies and Gentleman.

    I am purely using the Sigma DP0Q for location portraits which is my shooting style that love to take ultra wide angle. Here is my recent work that I did last Sunday. Minimal touch up for this image.

    Good to see you here Ken.

    This is a small community of Sigma users but I am sure they will be very interested in these examples and any future work you want to share.
