The Sigma SD14 is more than just another pretty face in the growing crowd of consumer DSLR cameras. The SD14 improves on the amazing image quality that was hallmark of its predecessors, the SD9 and SD10. The camera has also been refined with several new and much-needed features. I tested the SD14 primarily with a Sigma 17-70mm F2.8-4.5 DC Macro lens provided by the manufacturer.

Sigma’s latest entry in the SD digital SLR camera series features improved handling, along with several new bells and whistles. The camera is controlled by an easily viewed, 2.5-inch rear LCD, an updated four-way controller, three dials, 13 buttons and a red LED status control. The top-panel LCD now has backlighting with a dedicated button.

The newest Foveon X3 sensor is the major selling point for this camera, setting the SD14 apart from other digital SLRs and making stunning prints possible. Foveon’s X3 differs from other the CMOS and CCD sensors in other cameras. Instead of arranging colored pixels in groups, it has three transparent, colored layers (RGB). The theory is that this allows the sensor to collect cleaner, purer color information for better image quality. To protect the X3 sensor there’s a dust shield in the camera body just behind the lens mount. This round, quick-release shield is easily removed without tools and conveniently doubles as an infrared filter.

The SD14′s long-life shutter – rated at 100,000 cycles — makes a barely noticeable, but satisfying sound.

Sigma has moved in a different direction from its previous RAW-only strategy, finally providing the ability to produce JPEG files in the camera. Image quality can be fine-tuned with +/- adjustments (in 0.1 increments) for sharpness, contrast and saturation. The SD14 offers a choice between Adobe RGB and sRGB color spaces. Image files can be sorted into user-created folders in the camera’s file-storage area for easier review.

A flash-exposure compensation control with a dedicated button controls the built-in pop-up flash or an external hot shoe flash. The SD14 is also equipped with a PC connector to control studio flashes and wireless remotes.

The SD14′s sleek, black polycarbonate body is well-finished and rests easily in the hand. Gone are the SD10′s awkward handling and unnecessary heft. This camera will be most comfortable for those with larger-than-average hands.

A command dial surrounding the SD14′s shutter button selects the camera’s exposure settings: Program, Aperture Priority, Shutter Priority and Manual. Shutter speeds range from 1/4000 of a second to 30 seconds, plus a bulb setting.

Metering mode is tied to the multi-use function button and not displayed in the viewfinder. To select a metering mode, you must use both hands while looking at the top LCD. The SD14′s three metering modes — eight-segment evaluative, center and center-weighted average – address most lighting situations.

The quick-set white balance and ISO button displays a menu on the main LCD screen and is operated with the four-way controller. Also on the menu are five sensitivity presets ranging from ISO 100 and 1600, quality and resolution settings, and eight white balance presets, including a custom setting.

The Sigma SD14′s new, multi-point auto focus system particularly attracted me, since it was lacking in previous Sigma DSLRs. It offers five selectable focusing points, as well as an auto setting that chooses the highest contrast point. It also includes a built-in auto focus-assist light on the camera body, separate from the flash.

Camera Experience
Sigma grabbed my attention with the SD14 announcement, but continued release delays caused me some anxiety. However, despite some negative first impressions, after a thorough test I came away liking the Sigma SD14 more than I expected.

I started by taking the camera out one morning to shoot beautifully lit tiger lilies, pumpkin blossoms and flittering butterflies – perfect testing conditions. Twenty minutes later, I had a dead battery and a bunch of disappointing images. Color and focus were off and I had barely captured anything worthwhile. A beautiful red lily, for example, was way oversaturated due to bad white balance.

The next time I took the camera out, I used a tripod, the self-timer and the SD14′s RAW capture mode to produce decent flower and insect photographs at ISO 100.

The auto focus system’s six combinations of focusing points, I learned, did not perform uniformly or reliably. The auto setting only worked in the best light and rarely “found” what I wanted to be in focus. The auto focus-assist light helps in difficult low-light conditions, but it only works with the center sensor. Focusing with the center sensor worked as well as or better than previous Sigma DSLRs. However, the other four auto focus sensors were slow and unpredictable and I often had to reframe when using them.

The active AF sensor flashes, but does not indicate focus lock. I found this confusing, although it’s documented in the manual. The SD14′s focus lock is indicated with one single, separate light in the viewfinder. It’s different from other camera maker’s auto focus indicators, and seems counterintuitive. I was confused by both the AF sensor lock indicator light and the flashing focus point, neither of which indicated what I expected them to. In the end I found it best to ignore them both.

The auto focus point selection button is on the top of the camera under the user’s right thumb. Because it feels the same as nearby buttons it’s difficult to use without looking. Had this not been a test camera, I would have scored the button with a tool the first day so I could feel the difference.

My biggest complaint is that the SD14 requires too much looking at the camera and preparing to shoot. A camera this long in the making should be more current in design and offer more setting information in the viewfinder, rather than just on the LCD. It makes sense to have white balance, ISO, quality and resolution all on one menu; however, taking your eye away from the viewfinder to change ISO or quality might mean missing a shot.

Similarly, changing to a different resolution or quality setting in either RAW or JPEG requires looking at the LCD and thumbing through the options when you might otherwise be taking pictures. Also, like Sigma’s previous DSLRs, the SD14 is not a fast shooter in RAW mode. The camera is much slower than desirable due to slow file-writing times and the buffer filling up.

The SD14′s battery life was problematic. Sigma’s proprietary, lithium-ion rechargeable battery — which comes with a fast charger — seems to have limited cell life. It’s true that new batteries often take a few charge/discharge cycles to work their best. And after five or six full cycles, the SD14 was able to shoot 150 to 200 JPEG photos. But the battery indicator showed low power much of the time. Long exposures were particularly hard on the SD14′s battery life. Even after the initial break-in period, I exhausted a fully charged battery in less than 50 shots, 30 of which were .5 to four-second exposures.

Sigma SD14 pop-up flash
A welcome addition is the SD14′s built-in pop-up flash, which can also act as a trigger for wireless and slaved flash units. Sigma’s latest external flash was not available for testing, but a previous version from the EF-500 series worked fine. Flash white balance was right on target (see “Old Fashioned Couple” photo below). I had a few flash photos that did not work. And because the SD14 will not take a picture while the flash is recharging, it’s impossible to get a photo with no flash.

I upgraded the camera’s firmware and was pleased to find it was one of the better-documented and easier digital camera firmware upgrades I’ve ever made.

Previous Sigma digital SLRs only allowed RAW shooting, so the included Photo Pro software was an integral part of the camera experience. The SD14 can shoot JPEGs now and third party software like Adobe Photoshop Lightroom can handle the Sigma .X3F RAW files. So Sigma’s software performance isn’t as critical as it used to be. However, I did test Sigma’s included Photo Pro 3.0 software on a variety of computers and noticed a few issues:

  • This version was slower to load images than its predecessor, Photo Pro 2.1.
  • Processed files usually wrote more quickly, but adjustments were torturous on slower machines.
  • The software was prone to locking up.

Overall, I enjoyed using the Sigma SD14 DSLR. But I wish it had better auto focus, white balance and battery performance, as well as better menus and more setting information in the optical viewfinder.

Image Quality
The best proof of photographic quality is in printed pictures. Prints from Foveon-equipped Sigma DSLRs never cease to amaze me. When carefully processed from good RAW files, they are second to none. The new Sigma SD14 was no exception. Since the new camera has a JPEG mode, I also shot and printed JPEG photographs while testing the SD14.

The new Sigma has improved noise and bloom control for cleaner, smoother images with better controlled color saturation and detail. In addition to the bulb shutter setting, long exposures up to 30 seconds are now possible. The shutter speed capability of the SD14 is greatly increased over its predecessors and will meet most needs, short of astrophotography or other very long exposure work.

The SD14 produces X3F-RAW images in high, medium and low resolutions (2640 x 1760, 1776 x 1164 and 1296 x 864). JPEG files offer the same resolution options in basic to fine quality, plus a super-high, interpolated resolution of 4608 x 3072.

Sigma has gambled a bit by adding JPEG shooting to the SD14. Some might say it’s about time — everyone else has long had JPEG functionality. However, unlike RAW files, JPEG photos with bad white balance are much harder, if not impossible, to correct after the fact. The SD14′s auto white balance, incandescent and custom white balance settings were unpredictable in less than optimum light. There were also definite color and saturation shifts as ISO sensitivity increased. [PHOTOS] So in spite of the improved image quality of the SD14, JPEG capability increases the chances of less-than-pleasing photos. With RAW-only, previous Sigma DSLRs required attention in post-processing, but were very unlikely to produce final images with bad white balance.

After thoroughly testing the SD14, I’m convinced Sigma has once again delivered a photographic tool that makes clean, beautiful, detailed images. The SD14 isn’t perfect – it could make those beautiful images easier to produce across a wider range of conditions. Auto focus and white balance problems, along with questionable battery performance, make this camera a work in progress.

I’d suggest Sigma introduce immediate firmware improvements to address the SD14′s auto focus and white balance issues. Future camera designs should offer a RAW-plus-JPEG capture mode – standard on most digital SLRs now. I’d also like to see a 25 to 30 percent bigger sensor to better compete with Canon and Nikon full-frame digital SLRs. Sigma should also improve its Photo Pro software’s speed and reliability.

Sigma’s main business is lenses and they make lenses to meet all budgets and photographic needs. Their introduction of more “OS” image-stabilized lenses expand the SD14′s possibilities, while its Foveon X3 sensor produces high-quality photographs that keep it in the game — but barely. As far as image quality goes, the SD14 is an excellent camera. But in terms of functionality and features it’s lagging a bit behind the competition.

Who Should Buy It
Moving beyond the SD10 with additional controls and enhanced in-camera capabilities, Sigma aimed the SD14 at the larger DSLR market. New features and the ability to use older lenses and accessories also make this camera appealing to a wider range of photographers.

Those who will most appreciate the SD14 are current Sigma owners who’ve already invested in Sigma lenses, studio shooters and photographers looking for a high-quality image at a low cost.

    IWow.Image quality is impressive.
    Very informative review.

  • A remarkably balanced review in light of much of the trashing that has taken place already.

    Sigma have, in the meantime, “upgraded” the software by returning to an advanced version of Sigma Photo Pro 2.3. This has latest processing pipeline with better WB response, and it is quicker than 3.0. However, it does not have the same feature set as 3.0.

    The latest firmware includes outstanding ISO 50 performance, which is virtually noiseless.

    Finally, people often forget that the SD14 is the least expensive and (imo) best infrared camera around.

    The SD14 remains a bit quirky and hard to use for most people initially. However, once one has taken the time to get used to it, many of its “foibles” are forgotten or seen as strengths.

    Rick and Laurence,

    Thanks for taking the time to comment on the review!

    And MUCH thanks to Photo John for getting it finished as I had some intervening delays (will elaborate later elsewhere).


    Sigma has indeed continued with both upgrades in the firmware to address several issues, even though there are reports that the ISO 50 option does have dynamic range limitations beyond even the caution that Sigma offers with the firmware update.

    The revised 2.3 (from 2.1) Photo Pro v 3.0 is indeed an improvement. I’ve only used it very briefly, but it does not crash or at least not as dependably as v3. It doesn’t have the JPEG support most notably of the 3.0.

    On the IR score, the new style of easily removed filter/sensor protector is a real neat trick from Sigma that didn’t get the treatment in the review it deserved, but I didn’t shoot more than a handful of IR images and they weren’t ‘ready-for-prime-time’.

    In an upcoming blog I plan on adding a few more thoughts on the overall Sigma experiences I’ve had including some thoughts on comparisons to other cameras I use regularly.

    Shutterbug Magazine in the January 2008 issue has done a comparison of the Foveon Sensor to Bayer technology that is quite interesting. There’s a few comments I’ve got about it but will save for the near future other than to say I feel they made a fair comparison and my impressions and results do not differ widely in the Image Quality obtainable.

    It is nice to see a rare review of this camera. I had noticed that you chose to pass over that there are rather serious color problems starting at ISO 400 and above in your samples. Particularly noticeable is the train on the shelf. While the green in it is completely discolored other colors are bleeding. Some people have thought that the cause of these color problems are related to underexposure. However, if ISO 400 is a even a problem then isn’t this camera of a very limited use?

  • CD Price - drg says:


    The ISO related issues are mentioned, and specifically that there are white balance problems and color shifts that are noticed at increased ISO levels. This is in JPEG files. RAW files processed properly show significantly less color noise than previous FOVEON equipped cameras. The SD14 does very little in camera processing compared to the competition, which may be a weak point for some types of application.

    The Tungsten White Balance issue for JPEG and even in the 3.0 version of Photo Pro when applied to RAW left much to be desired without ‘adjustments’. This appears to have been remedied with a firmware release, and the images I made during testing appear to benefit from a later release of Sigma’s Photo Pro package that also addresses several problems. This software and the latest firmware updates which include an option for ISO 50, were not available at the time of the original testing.

    A few sample images in my gallery, i.e. one entitled “Vignale Nero”, was post processed with a customized profile via ADOBE Lightroom & Photoshop CS3 and though it is an 800 ISO image, the results are obvious. It wasn’t specifically listed as a SD14 image as it was a result of more post processing than is typical for other than a few users.

    Any digital sensor is prone to some problem as a result of under or over exposure if great enough. More of a problem at first with the SD14 was the inconsistent results rather than what could be obtained with a bit of patience.

    There are some limitations and the Foveon equipped Sigmas aim at a rather different market than the average DSLR in a similar price range. As I noted in the review, Sigma is trying to appeal to more users. They still have a way to go, but do have a very unique product to offer to those who need or want it.

    Thanks for your commentary

    I found everything negative I read about this camera to be very true and
    anything positive to be just barely true. Granted, with a lot of work you
    can get a good picture out of this camera but you better be familiar with DSLRs
    and know what you are doing technically.

    With considerable work in PS, you can produce a good photo but
    if you are that experienced you are going to ask yourself, “Why
    am I bothering?”

    I think a lot of people buy this camera and than give in to their
    need to justify their purchase and avoid the personal embarrassment.

    Sigma just doesn’t cut it with this. I wouldn’t give this camera to someone,
    even if I got it for free.

    Thanks for reading.

    Wow, why are people being so harsh? Honestly, the camera isn’t that bad and the only real issues I’ve found are with the white balance which are easily remedied with an expodisc (which I used with other cameras anyway)…

    As for the detail though, it is clearly superior to other brands with the closest MP to MP that I’ve found coming from Fuji Sensors but the Sigma still had an advantage over the 6.3 MP Fuji (technically 12 MP Fuji as film had both low and high sensitivity emulsion layers as well and we wouldn’t call those fake)…

    Anyway, reality is that this camera is very capable and isn’t as bad as some make it out to be, I’ve given it enough of a shot myself and really love what I’m getting out of the body in terms of color and clarity when using SPP and RAW (again RAW is what I’ve always used with these cameras anyway).

  • Martin says:

    Having shot with Nikons for years the Sigma came as somewhat of a culture shock. Feature wise the SD14 is miles behind the latest offerings …. but the key to this camera is understanding the RAW output. While Sigma’s Photo Pro software is not the best, the latest version is fast and great for quick RAW adjustments. Having used Nikon Capture for years my preference is to adjust the White Balance is Sigma Pro, save as a TIFF, open back in Capture to make use of the superb feature set and then save to JPG.

    To sum up, the SD14 is not a camera for the casual shooter, you really do need to understand that Image Quality is everything to it – this is where it really delivers. If you want to take it out on a Sunday afternoon and shoot dozens of frames and expect them all to be useable then this isn’t the camera for you, it excels when some thought is taken into the process, it then can just shock you with one killer image that makes everything else just plain dull.

    If your concerned with the feature set then your probably more tied up in the Canon v Nikon technology race than your photography. The SD14 gives you the raw tools and expects you to do the rest. In someways Sigma should be appluded for not following the herd.

  • Photo-John says:

    Thanks for postng your thoughts and experience with the Sigma SD 14, Martin. I agree that the feel and performance of the Sigma cameras is a little awkward. And I also agree that the image quality is something special. If you’re willing to work slow and put in the post-processing effort, you will be rewarded.
