Just posted: JPEG and Raw samples from the Sigma SD1. We've been using a production Sigma SD1 for a little while now, and although we have only just started our studio testing, we want to share some of our early 'real world' samples with you. In this gallery you will find images of a broad variety of subjects, shot at different ISO settings, in both Raw and JPEG mode (albeit using, for now, a very limited range of lenses). We have converted the Raw files using Sigma's Photo Pro 5.0 software 'to taste', and performed some minor tweaking of the resultant TIFF files in Adobe Camera Raw.

This gallery contains both JPEG and Raw files, in many cases shot simultaneously. When converting the SD1's Raw files, we have tried simply to get the most out of them using the software available. We converted each file individually and followed no particular workflow. As such, we have deliberately not included any firm conclusions here about the SD1's image quality – we have simply used the camera as an end-user would: with the aim of getting the best results possible, both in-camera and via Raw conversion. We're working on the review at present and will publish additional information, including studio shots, as soon as we can. 

Samples gallery

There are 41 images in the samples gallery. Please do not reproduce any of these images on a website or any newsletter / magazine without prior permission (see our copyright page). We make the originals available for private users to download to their own machines for personal examination or printing (in conjunction with this review), we do so in good faith, please don't abuse it.

Unless otherwise noted images taken with no particular settings at full resolution. Because our review images are now hosted on the 'galleries' section of dpreview.com, you can enjoy all of the new galleries functionality when browsing these samples.

I have experianced terrible autofocusing with my sd14 so I am leary about investing in another sigma. When my focus is perfect, I can print a 5' x 7' print from a raw saved as a16 bit tiff and see no pixels. With the new SD1's 46 mp I cant imagine any canon or nikon coming close to the size and clearity. I just wish i could trust the autofocus. It my be just my camera but i know it isnt the lenses as it does the same thing with all 3 of my sigma lenses. Canon i have to admit has superior autofocus. I also wish the SD1 had luve image and video options but video may not be possible with foveon sensor.

The camera will do better with matched lenses of which there are few. The best ones to date are the 70-200 OS; 50 f1.4; 85 f1.4; 70 f2.8; 50 f2.8. The 8-16 does reasonable well.

The 18-50 f2.8-4.5 OS is a good lens for the money ($200 last time I checked), but is not a good enough lens for this camera.

The comments in this thread with the most hyperbole seem less relevant to me. I'm sure the SD1 is capable of excellent results and may be tricky to get the best out of.

Nothing conclusively bad about these images, with a few glimpses of excellence. Just have to wait and see...One thing's for sure, I won't be waiting in line for one now that I just checked my bank account balance. ;)

I find the images at high ISO kind of crunchy looking. Even what should be (based on what the range of luminance in the subject appears to be) pure black has luminance noise "texture." That's something also common with the m2/3 cameras, even at lower ISOs, but it is a bit disappointing to see it in large shadow areas even after processing from RAW.

And a big ditto ditto to "Sigma needs better lenses for this camera." I find the edges of many of the images to be appallingly un-sharp, sometimes just soft, sometimes linear-blur soft.

Britton ,
i suggest visit some of the threads in the sigma forum where they have found the best way to iron out some of the issues like SPP and also the lens that have been proven to produce good results. I heard things like the default spp sharpens too much the image which in foveon is already supersharp and needs -0.5, using silkypro etc.

I thought that the sample pics labeled "RAW" were supposed to download as Tiff files not JPGS? (Well really they're supposed to be RAW.)

For example sample # 29 RAW (real number 1383077) downloads as a 15.5MB jpg, I guess that may mean it started life as a RAW file. While sample #26 (1383074) downloads as a 6.6MB jpg, so I guess that one started life as a jpg.

What is this mess? Post RAWs if that's what the headline says--I can do my own conversion to tiff, and then maybe to jpg, if I want to send the file to someone via email.

That's great about the final future review. Now let me explain something about the first sentance of the DPreview paragraph, it states: "Just Posted: JPEG and RAW samples from the SD1." That statement DOES NOT mean well there are some JPEGs up on DPreview which stated life as RAW files.

"RAW conversion workflow", you get that's a misuse of the word "workflow". Workflow doesn't mean this is the history of how we got this jpeg.

Change the first paragraph to accurately reflect what kinds of JPEG samples from the SD1 DPreview has posted. (Whatever, some start out as RAW files, who cares if that's no what's been put up here.)

Gee I was excited to download those "RAW" files, and now I've wasted time.

For Fotopizza

There doesn't seem to be much support for your assertion about the SD14 dynamic range superiority from lab tests. It does appear that the SD14 is balanced such that it has better highlight headroom than in typical but that is at the cost of noisy shadows. I'd be interested to see your comparisons of shadow performance between the SD14 and K5.

I tested the SD1 with Sigma`s 70mm Macro, 105mm Macro (old version), 50mm 1.4 HSM and 17-50mm 2.8 HSM OS. The good news: all of these lenses delivered an extremely detailed and sharp output- even the zoom lens, and this was a surprise. Another good news: The 50mm 1.4 HSM always had a problem with focus shift between 1.4-2.8 on my SD14. Really annoying. But, don`t ask me how or why, I`m no technician- focusing was spot on with that lens too on the SD1! First time it was really fun using that lens on a Sigma camera. So, there are good lenses that resolve great detail out of that camera. But unfortunately- the SD1`s internal buffer is not big enough and writing speed to fast CF cards is so extremely slow- as slow as a SD14. So that is one point that can really spoil the fun...

High ISO still being that poor is probably a matter of SPP not working properly. You can`t expect magic from the in-camera JPEG engine.
When it comes to resolution... Take a picture of a (preferably sleeping) cat, especially that extremely fine fur around the nose.
Shot with good Macro lenses on all 3 cameras, the SD14 outresolved a D700 and a 50D. Just because their output was larger this does not translate into more detail- it was just more blurry-something without any detail in the fur.
And when it comes to DR- the SD14 performes almost better in that way than my PhaseOne P45+ Back- if you now how to correctly expose a Foveon camera.
High ISO of course has always been poor- everything from ISO 400 on was just bad with the SD14. But have you ever wondered why no colour-resolution tests with coloured Siemens stars in different colour combinations between Sigma and any other camera are performed? I think, let`s wait and see how the SD1 performes with a working SPP.

DxOMark says 12.9 Evs for the P45+.
PhaseOne says 12 f-stops DR...
...the SD14 has about 10.5 stops useable DR and if tweaked approx. 11.5 stops, but not 12 or more:

or for reference the DP1 with the same sensor than the SD14 - measured at dpreview:

Sorry, but I would think that the PhaseOne with at least 12 stops has more DR than the SD14 with 10.5 useable for color and max. 11.5 stops for B&W ;-)
The SD14 would need at least more than the 12 bit per channel it has and good cooling to get a DR above 12 Evs...
...the SD1 also. ;-)
Maybe You should have Your PhaseOne P45+ Back checked, if it does not deliver a better DR than the SD14...
...or maybe it is getting to hot because of the scenes it has to capture. :-))

SMILE! Hot scenes? Not really- I`m doing mostly industrial photography.
My first back was a Mamiya ZD Back- which was not nearly as bad as competitors like Leaf or Phase One always said. The output of that Back was visibly better then the output of a 5DMkII- the SD14 outperformed it DR wise. My current Back from Phase One is fine, great DR, and I always said the SD14 ALMOST reaches the DR of it. ALMOST. Yes, I saw those tests too- around 11 stops if exposed Foveon-style and processed reallllllllllly carefully is what I would guess. And you can still push the limits a bit. But I never saw a similiar output from any other DSLR I have worked with. And I`m afraid the SD1 will not be pushing the limits DR wise. After my little test session with it, I believe it has lost DR compared to the SD14. But I wish you were right and I would capture more hot scenes! Great Post! Thank you very much!!!!!

Oh, when I saw "RAW" in the headline, I thought downloads of RAW files would be available, not 16 bit Tiffs made from RAW files.

Yes, I know that Sigma hides Sigma Pro Photo 5.0 on a special SD1 website, but it's software one can get without buying the camera, and I'd really like to do my on RAW processing, even if SSP isn't the greatest piece of work (a point made vociferously over that Luminous Landscape's full SD1 review).

Don`t waste your time. The latest SPP fills your image with strange luminance noise patterns that make you cry and run away. That is really a shame for such an totally overprized camera. I can at least expect the Raw converter being perfect and ready to use if I shell out so much money. At at the moment, since shooting JPEG has always been a bad idea with Sigma cameras, no other Raw converter is available for SD1 files and the only one that is, is not working correctly, I don`t see the point in testing the camera right now...

While I'm willing to believe your point about SSP 5.0, I'd still like to experience it myself, and that's why DPReview should post the RAW files.

For that matter sample number 29 RAW (a US pay phone) shot at ISO 3200 looks usable, but I can't be sure if I can't process the RAW file myself.

I agree entirely. But be aware- SPP is still slow (and I`m running it on a twin-8-core 32GB RAM MacPro), constantly crashing, and it will drive you crazy... But sure, there`s nothing better but processing yourself. Be advised, the stripe-like luminance noise pattern you will see in the blue sky (when opening such a RAW file in SPP) is created by SPP- it`s a bug. Nothing to do with the camera.

Using SigmaProPhoto 5.0, I've opened the smaller DP2s' RAW files on my quad core Windows 7Pro laptop without trouble--with "only" 8 gigs of RAM. I'd still like to see some RAWs from an SD1, and frankly there's no reason DPreview can't post them here tomorrow.

From reading various comments on the SD14, SD15 and DP series cameras at Amazon or B+H, I seem to remember some Mac troubles with the SPP 4, though I'm not sure.

Sweet Mary mother of god, my eyes are bleeding haha. Certainly some pretty sharp 15mp APS-C pics here, especially with the macros and the 70-200.

Still, I can't say a 5D Mark 2 with a removed AA filter would not be just as good detail wise downsized to 15mp while enjoying many other advantages.

Would be a lot more impressive for $2K to be honest.

The test here was performed with a production SD1 with latest firmware. Again, the problem right now is the Raw Software Sigma Photo Pro SPP. Since no ther software maker supports SD1 files, you have to fall back on SPP- but that very SPP can not properly handle these files at the moment. It even renders additional luminance noise in stripe-patterns into images shot in bright, high contrast conditions. RAW is, and has always been, THE Sigma camera strenght. Sometimes SPP 4, and sometimes LR or Silkypix was the weapon of choice. But unless Sigma rolls out a bug free SPP version that can really handle the SD1 files, we will never see the true potential of this camera. Guess we still have to wait a little. Sad but true, for a camera that comes with that price tag.

Although these images look good below ISO 800. I see nothing better worth the price tag. I am hoping this is a preproduction model with preprod firmware DP has otherwise my $1700 E-5 gets images this sharp. Again the images look very good at low ISOs so if Sigma work out the higher ISOs (which with this HUGE sensor should not be a problem) the camera will be fantastic. Until then not worth the $$$$$

The sensor is not huge, it's a normal 1.5x crop sensor, like all cheap dslr's. High-ISO was one of the major problems in the old Sigma's, which had much larger pixels.

I have just tested the SD1 myself. In daily work I use Mamiya RZ67 with PhaseOne P45+ Back, Sigma SD14, or occassionally Pentax K-5, Nikon D700, Sony A900.
My own SD1 test was performed with: 105 + 70mm Makros, 50mm 1.4 HSM, 17-50mm f2.8 HSM OS. ALL of these lenses showed exellent results and enormous detail resolution at low ISO, even the zoom lens. The SD1 lacks the enormous highlight DR I`m used to from my SD14, that`s sad. Still, the clean and detailed output at ISO 200 blows everything away that the CaNiSoPenOly community has to offer right now. I would even prefer my SD14 over K5, D700(0), 7D any time- but only as long as the sun is shining or I`m in studio. SD1: Everything above ISO 400 is unsuable at the moment- less so because of the noisy sensor output, but the only RAW software for these files is SPP at the moment- and SPP is so full of bugs- it really can`t handle these files, and very often, it totally spoils or damages the output. Let`s wait untill SPP is working. Dennis

I don`t understand your post. There is no ISO 50 on the SD1.
ISO 50 was available with the SD14 / 15. It had more cons than pros, since ISO 50 on a SD14 crops your highlight DR- and DR is one of the major advantages of the SD14. I really don`t care about DR tests here- I can do my own test and compare my SD14`s DR to the DR of my P45+ Back- and the SD14, IF EXPOSED CORRECTLY, almost beats the P45+ in terms of DR. I also have a K5 in my shelf- I`m only using it in bad weather. On a bright sunny day, the SD14 outperformes the K5 in DR easily (if OVER-exposed correctly) and in terms of sharpness, the K5 produces a bigger output file, with more pixels translated into a blurry-something-anything but details, while the SD14 produces more detail- and detail in the detail. I`m talking of RAW-files at base ISO only, since I need to be obsessed with IQ. High ISO of course is a different thing, the SD14 is years behind here.

So after 6 years of using Sigma and 5 years of working with digital medium format I now realize that is was all just figment. Who knew... Smile. No, seriously. Foveons usually must be over-exposed. Shadows can not be lifted as you can do with other cameras. Even if you try, you will become a victim of the Foveon typical low-light noise: chroma noise in dark, neutral-coloured areas (like steel, concrete, asphalt). But the recovery of extremely bright highlights is just easy with the SD14. When I underexposed a K5, or a D700 for that matter, the way that I get similar nice highlights without clipping and with so much detail, I would be forced to lift the shadows to such an extent, that they just look terrible and filled with so much luminance noise that overlays fine shadow details, that I prefer leaving these shadows as dark as they are. DR wise, I do find the SD14 runs rings around K5 and D7000. No wonder a colleague in UK sold his D3 and A900 for a SD14 to do twilight city panos.

Please dont get it in the wrong way, im not in anyway critisizing you or your abilities as a photographer. Your claims just make no sense. DR has nothing to do with preserving the highlights and fillimg the shadows and then see what the results are. BTW, all tests (by professionals) showed clearly that shadow noise in sonys sensor (D7000, D5100 and K5) is veryy little, so your cameras must be defective. And BTW, i do jhave a DP1s, and made tests against a D300 from a friend of mine, and his camera has a little bit of better DR...and as you observed, my Dp1s shadows when lifted, pretty much SUCK...much more than bayer cameras...even so, the SD1 seems better regarding this...

I believe that- but again there is a big difference between the DP1s and for example my old, first series DP1, especially in DR. As it is between the SD14 and SD15. I can`t believe that all cameras I touch are defective. I`m more than disappointed when it comes to the base-noise, mostly luminance noise at base ISO, I see in files from the K5, D7000, D700 or 7D- and I have used all of them in the last 12 months on the one or the other occassion. One might say that I`m totally spoiled by the absolutely clean output output when overexposed at ISO 100 in good light from a SD14, or from the clean output at ISO50 from my P45+. And I`m for sure no fanboy- I use the tools necessary to deliver my clients the IQ they demand. But when even they ask "can you please use the Sigma for that job- we don`t need huge print sizes but we need these >wow-effect-3d-like-pictures<".... Compared the creamy-clean blue sky delivered by a ISO100 SD14, the output of a ISO 200 K5 or D700 is just grainy...

And yes, as long as the light is good and base ISO can be used, I prefer the SD14 over the 7D. Surpress the base noise at base ISO 7D down to the base noise level at base ISO of a SD14- see whats left of fine details. Try the "sleeping-cat-test". Whas that here,where a colour-resolution-test was performed between a DP2 (?) against a D90 and a M8- the one and only time such a test was done? Interesting how the resolution of a M8 dropped below 900 lp in certain colour combinations. And placing more photosites on the same size sensor like today brings all of a sudden a better output? Aha. And yes, I do find that DR as much to do with how far is the distance between the darkest and the brightest point, untill details disappear at both ends- and how far can I push those limits in Raw processing. My colleague in UK did his well selling twilight-hdr-city-panos with his D3 and later a A900 (6-frame brackets)- untill he tried the SD14. He sold the NiSo gear. And does only 3-frame brackets now.

@fotopizza,

I own a DP1, 2 DP1s and 2 SD14 and they have all the same dynamicrange.
-
There is no and certainly no big difference between the DP1s and the DP1.
-
They all have a DR below 12 Evs.
So every camera that has at least 12 Evs of DR like the PhaseOne P45+, the K5 or D7000, have for sure a bigger DR than the SD14...
-
...if not, they are really defective, or Your post processing isn't that suited for those cameras. ;-)
-
Just leave it as it is:
The SD1 could deliver the best per pixel sharpness,
if used with a lens that has a higher resolution than the sensor in it's diagonal
AND if used without mirror slap on a tripod
AND if used with a proper Software like Silkypix Pro,
which preserves real pixel detail of .X3F whilst giving the output the needed sharpness to see those details:

With all due respect....
"So every camera that has at least 12 Evs of DR like the PhaseOne P45+, the K5 or D7000".....
K5 and D7000 and more than 12 EVs?????
Aha. Either I have missed something, or you mean the K5 and D7000 models that will be introduced at photokina in 2016...
No difference between DP1 and DP1s? Aha.
"Your post processing isn't that suited for those cameras. ;-)"
That is it probably. I`m just too stupid to operate Capture One, Lightroom or Silkypix. How can I run a company, stupid as I am. Let`s settle this with the fact that all my cameras are defective and besides that I`m way to stupid for post processing anyway. So, you are right, and I bail out here. Don`t need to convince anyone with a pre-fixed opinion, and it`s not the first time that CaNiSoPenOly users react like this. As long as my clients see the difference, it`s fine with me- for this conclusion my limited brain power is just enough. Good night my dear friends. No hard feelings. Have fun here.

How I did get my results, so that one is able to reproduce it.
-
My method has the advantage (in comparison to the dpreview method) that You can achieve a software independent result for the true dynamicrange. ;-)
-
dxomark says 14.1 Evs for the K5
and 13.9 Evs DR for the D7000.
-
Even if You substract 1 Ev for the difference between max. DR and useable DR for color pictures,
those cameras have more than 12 Evs,
which is more than the SD14 / DP sensor has.
-
My opinion is certainly not pre-fixed, but based on reproduceable measurements.
-
In addition I am currently no CaNiSoPenOly user,
but a FujiSamSig. :-)
Due to my experience with Sigma, I'll probably add a "So".

No need to take it personal, but I like RAWs.

Just for clarification:
-
The big difference between DP1 and DP1s is especially not in DR but in color reproduction, AWB, suppression of reflections and UV+(N)IR sensibility.
-
However, if one looks at the useable DR for color reproduction within SPP...
...then the DP1s is more than 1 EV better than the DP1 and not vice versa!
-
I like to emphasise the words "color", "reproduction" and "SPP" as the key words in CONJUNCTION with "more than 1 EV better"... ;-)

...and I like to close this with Your wise words:

Wow, what a poor lens to demonstrate the camera. Not one shot looked very sharp. Really, a 18-50 f/2.8-4.5 is the best they could do?

Hi, just a suggestion, it would be great if DPR also include the comparison between SD1 with some cameras without AA filter like M9 or HotRod-ed Nikon cameras, so we can understand whether that sharp images is exclusive to Foveon sensor or not.

It appears to me that quite a few of these images are under-exposed and look pretty bad because of it.
Not using exposure compensation and getting bad photos is the sign of a careless/hurried/ridged photographer-- using default/basic settings at-all-costs for the review [big mistake], is not the camera's fault when shooting in the 100-1600 ISO range. I certainly speak from experience-- I shoot with E-30 and E-510 Olympus cameras.
(I've seen this same problem with many other DPR review images and it causes unecessary 'pseudo-noise' in the dark areas.)
These images don't look they came from a camera worth what Sigma is asking for it!
That, together with a rather slim selection of high-enough, quality lenses for this camera's sensor probably won't generate enough sales to recoup their investment!
Its a shame, if it had a low enough price and better selection of lens I could be interested in the SD1.

Almost all of these images were shot in auto-bracketing mode, and the image closest to the 'correct' exposure was chosen. On a properly calibrated monitor, none of these images appears underexposed.

Few thoughts:
- iso 400 is close to clean (well, maybe NR soft bundle?);
- sigma finally has a device to check lens centering (look at house with blue sky);
- not bad details, but not sure if it is worth the money.

I was very excited to look at these, but I have to say I'm anything but impressed. I don't see the 'amazing detail' others seem to see here.

I agree with a previous comment that these looks oversharpened but don't seem to have the detail I would have expected from a true color pixel sensor.

I also don't think the colors looks particularly impressive, but that's no surprise. The second and third layer color channel is suffering from light loss of the layers above. The signal to noise ratio can't be anywhere close to Beyer sensor, thus it has a clear disadvantage in terms of colors.

The best detail I have seen recently was the samples from the Samsung NX200. That camera even outperforms the Sony A77 and is sharp into the corners and is amazing at handling contrast.

Low ISO images are incredible. This is what the SD1 is all about, not high ISO performance. The downside is that this really shows up the weakness of the lenses. The outer frame performance looks dreadful on pretty much all of these shots - soft with lots of chromatic aberration. Sigma need to release 1 or 2 high performance prime lenses to go with this sensor. Not necessarily wide aperture but sharp across the whole frame.

On my SD1, one of the lenses I've really appreciated the results from is the 17-70 OS. Not the 17-50 F2.8, but the cheap wide-standard, close-focusing zoom.

Incredible Low ISO images are trivial for a sensor with all necessary informations in one (3 layer) pixel...
-
...what else should such a sensor show, if one uses a lense that can resolve higher than the sensor. ;-)
-
The problem is shooting with a really available (not preselected) lens, without tripod and with mirror slap...
-
...real life conditions are the true problem for the SD1.
-
The only reason I would consider a SD1 (below 1000$) is for testing lenses... :-)
...under controlled studio conditions.
A nice "buy" ;-) for test sites like dpreview.
-
But for real life photography, I wouldn't even consider 1000$ for the SD1, because of the existence of other cameras (for real life photography) in the market. Period.

I can just remember when I first came to this site the sample photos were the images that sold me on a camera or at least gave me a good idea of what was capable from the camera. Recently it just feels like DPreveiw has just a few hours with the camera outside of the studio for testing. Nothing against you Barney!

Ouch! Jagged edges all over the place and a LOT of color bleed on even moderately high ISO. Just look at the first photo... The red is bleeding all over the place. But, to be honest, many of the shots look bad simply because the lens used sucks. I do like the details, but it seems this camera will perform best in controlled environment such as a studio.

The color does seem to be very 'deep' or something, and in that sense i do see what they're saying about film-like. But once you up the iso, the noise is nothing like film and horribly digital, but then this is more of a studio or well-lid outdoor shoot camera with fancy lights and reflectors by ppl who have that kinda budget, so that isn't much of a problem. But it gotta see some side-by-sides with a regular bayer sensor cam for the true difference in color rendering (with the same lens)!

Well...guess I'll be the one to rain on the parade. What I see here offer the typical Foveon "look" that some people claim is "film-like." I'll go ahead and disagree that there is nothing film like about these at all. What I see has the normal look of a lack of AA filter...in other words, aliasing artifacts on high contrast transition areas. Color no better than any Bayer camera. A look that appears someone has applied a USM of 500, 0.2, 0.....twice....even when no sharpening is applied.

The sad thing is if these were posted in a Canon or Nikon forum, no one would claim any special look...other than having issues with the high ISO color shifts and oversharpened look of the images.

I love the IQ (of the "from raw" files). At 100% the images look somehow different to (and better than) ones from the Bayer sensor. Reminded me somehow the film's IQ.

Hope the patents for similar tech we have seen from Sony and Panasonic would bear fruits in the near future.

Completely agree with fotopizza re SD14 and it's dynamic range. In bright light or studio the SD14 made my 5D look weak. Trouble is it had a limited ISO range (actually best to stick with 100 ISO only) and slow processing speed, poor battery life etc. Must say was much more wowed by SD14 images than anything I have seen from the SD1 yet. Maybe for Foveon bigger pixels are better pixels.

@ Dougbm_2

Your old 5D has less dynamic range than the SD14 and the 5D MK II...
...no surprise, if one believes DxOMark.

Because they say for the 5D 11.1 Evs, which is probably for B&W and for color it could maybe be around useable 10.1 Evs.
-
But this is not the whole story, because the SD14 does not exceed 12 Evs...
...others do. ;-)
