Sigma introduced its first digital SLR camera, the SD9, to the market in October 2002, and has established strong support from a wide range of photographers both amateur and professional alike. The second model, the SD10, released on to the market in November 2003 continued to build on the support of loyal photographers. However, demand for JPEG’s greater convenience in image handling has increased and in order to meet this demand the new SD14, powered by Foveon X3® direct image sensor, now includes JPEG mode with high image quality, high performance and versatility.
The Foveon X3® direct image sensor featured in the Sigma SD14 digital SLR can capture all primary RGB colors at each and every pixels arranged in three layers, insuring the capture of full and complete color. Using three silicon-embedded layers of pixel sensors, stacked to take advantage of silicon’s ability to absorb red, green, and blue light at different respective depths, it efficiently reproduces color more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor. Until now, all other image sensors have featured a just single layer of pixels and each pixel captures only one color of light, which has been filtered through a single color filter. Since conventional image sensors of Bayer pattern filter mosaic capture only one-third of the color, complicated computation is required to interpolate the color they miss. Interpolation leads to color errors, color artifacts and a loss of image detail. Low pass filters must then be used to reduce color artifacts. The use of low pass filters adversely affects sharpness and resolution of the final image captured.

The SIGMA SD14 incorporates both RAW and JPEG image recording formats enabling photographers to capture the highest possible picture definition and small file sizes. There are four JPEG recording modes: Super High (14.15 million pixels: 4608×3072 pixels), High (4.64 million pixels: 2640×1760 pixels), Medium (2.1 million pixels: 1776×1184 pixels), Low (1.03 million pixels: 1296×864 pixels). Super High can be used for A3 (297×420mm / 11.6”×16.5”) or larger prints. High for A4 size (210×297mm / 8.2”×11.6”) printing. Medium can be used for regular size printing. Low can be used for web-page and e-mail transmission. There is a choice of three JPEG recording quality: Fine, Normal and Basic.
The SD14 comes complete with SIGMA Photo Pro 3.0 software, a RAW image developer that converts all RAW data quickly and easily. Adjustments can be made in three separate modes. The X3F Mode stores the original settings of the image at the point of capture. In the Auto Adjustment Mode, the software analyzes and automatically makes adjustments to the RAW data. The Custom Mode allows the photographer to make individual adjustments (exposure, contrast, shadow, highlight, saturation, sharpness and fill-light for example). Subtle or dramatic changes can be made by the photographer easily and quickly by simply adjusting the slider controls within the software.
The X3F Mode stores the original settings of the image at point of capture. Photographers` personal modifications can be saved to the RAW, X3F file for future use. SIGMA Photo Pro 3.0 supports 8-bit TIFF, 16-bit TIFF, and JPEG file formats and also outputs images in color space (s.a. sRGB and AppleRGB). The default setting for resolution is the same as the resolution selected when capturing the image on the camera (High, Medium, or Low). It is also possible to half, (for sending via e-mails) or double (for high quality enlargements, max. 18.58 million pixels:5,280×3,520pixels)the resolution when processing the image.
The new auto focus sensor features 5 focusing points (center, left, right, up and down) ensuring consistently fast and precise focusing. The AF metering features a cross type sensor in the center of the screen. Selecting the AF point can be done automatically or manually by photographer.
Most digital SLR cameras are typically vulnerable to dust entering the body especially when the lens is removed for changing. Dust and dirt entering through the lens mount of a digital camera can be seriously detrimental to image quality. The dust protector of the SIGMA SD14 prevents dust from entering and adhering to the image sensor. Even if dust adheres to the dust protector it will not have an adverse influence on image quality as the dust protector is located away from the image sensor and is therefore out of focus.
The new layout of control buttons insures quick identification of the desired functions and easy use of the multifunction interface in operating camera settings. Clearly marked buttons make it easy for the photographer to display and adjust the most important settings, namely ISO, resolution, JPEG quality and file type, and white balance, on one screen, using one button. The top LCD panel incorporates a backlight, which enables the camera to be easily controlled in low light or dark conditions.
The durable focal plane shutter mechanism has life cycle of over 100,000 exposures. The shutter is ideally suited to the requirements of digital cameras. This new shutter dramatically reduces the amount of dust and dirt from the shutter mechanism. The photographer can enjoy taking pictures without worrying about dirt and dust adhering to the image sensor either from inside or outside the camera.
The SD14 features a continuous shooting speed of 3 frames per second. Continuous shooting can be accomplished in conjunction with the camera’s predictive auto focus function when photographing fast moving subjects. The camera’s high-speed image processing circuits are capable of handling large data files generated by the high-resolution 14 megapixels high quality sensor. The number of images that can be captured in continuous shooting mode is dependent upon the resolution setting; High - 6 frames, Medium - 12 frames and Low - 24 frames. These figures apply in either RAW or JPEG mode.
The Sigma SD14 is equipped with three types of metering mode: 8-segment Evaluative Metering, Center Area Metering and Center Weighted Average Metering. This enables the photographer to select the metering mode depending on subject and situation. Exposure compensation function allows the photographer to override the exposure value set by the camera’s exposure meter. Auto Bracketing function allows the exposure to be adjusted by 1/3 EV increments up to ±3 EV from the exposure automatically set by the camera. In situations where it is difficult to determine proper exposure, the auto bracketing function allows a sequence of pictures to be taken of the same subject at three different exposure levels; Appropriate Exposure, Under Exposure and Over Exposure.
The SD14 is equipped with a newly developed pentaprism viewfinder, which has 98% (vertical and horizontal) coverage with 0.9x magnification, an 18mm eye point and –3 to +1.5 dpt dioptric adjustment.
The SD14 camera features a new, large 2.5 inch, 150,000 pixel resolution LCD monitor. The LCD monitor displays 100% of the image, allowing the photographer to easily and accurately confirm the image composition. It features playback options including single frame, thumbnail display (9 images), and three types of magnification (which is achieved by use of the 4-way controller). Shutter speed, aperture and other settings can be seen by pressing the INFO button. The large menu interface makes reviewing images and navigating menu options easy.
The Sigma SD14 camera’s built-in flash offers an angle of coverage of 17mm (equivalent to 28mm with 35mm full size) lens with a guide number of 11 (ISO 100). Built-in flash can be synchronized to a shutter speed up to 1/180 sec. This built-in flash enables automatic S-TTL shooting, which allows simple, easy control of advanced photography techniques.
The mirror lock-up mechanism raises the mirror thus preventing vibration when the shutter is released. This prevents camera shake, and is especially effective for macro photography, using extremely long telephoto lenses or scientific work. Use of a remote controller (sold separately) or cable release (sold separately) also reduces the possibility of camera shake.
The top LCD panel allows the photographer to quickly and accurately confirm information such as resolution setting, metering mode, battery status, and the number of images that can be recorded on the CF card. It also incorporates an orange backlight, which enables the camera to be easily controlled in low light or dark conditions.
The Lithium-ion Battery BP-21 (included with the camera) can shoot approximately 500 images on one full charge. It takes about 120 minutes to fully charge with Battery Charger BC-21 (also included). The optional power grip PG-21 has a vertical shutter release button and can hold two BP-21 batteries, supplying more than enough power for most shoots. The AC Adapter SAC-21 (sold separately) enables the Sigma SD14 to obtain power from the mains supply.
The SD14 can be used with over 40 Sigma lenses such as ultra-wide, ultra-telephoto, macro, and fisheye. The EF-500 DG SUPER, EF-500 DG ST, and EM-140 DG for Macro Photography flashguns offer fully automatic S-TTL flash dedication. Other accessories include the power grip (PG-21), cable release (CR-21), remote controller (RS-31) and the AC adaptor (SAC-21). These accessories ensure that the SD14 system is both user-friendly and versatile.

I dont think that the real final picture has one frame with 14 mb resolution. at sigma one has to divide this 14 by 3 and this is the actual framesize because they split this 14mb into rgb so the final actual picture resolution is somewhere between 4-5 mb and this resolution is rather poor.

The 14MP JEGP is interpolated from sensor data. The unstated issued is once interpolated from the sensor data, how much compression is applied to the JPEG when it is saved to the card,
( eg. Level 8 vs. Level 12 in PSE 4 )
A reliable report indicates the SD-14's 'effective' resolution is plus 35%
of one layer of the Foveon X3 chip:
2652 x 1769 = 4,691,388 + 35% =
6,333,378 'pixels'.
However these pixels are adjacent to each other on the sensor surface and there is
no 'guessing' as to the color and intensity of the light hitting neighboring pixels.
On standard CCD/CMOS there is a great deal of 'guessing' as to color at adjacent pixels as they have only 25% RED, 25% Blue and 50% Green.
On the Sigma SD-14, interpolating upto a 14 MP JPEG is not much of a problem regarding the detail and color of the original sensor data. If Sigma save an almost 'lossless
jpeg' to the card, thi is significant news IMHO.
With all of this promise, I am astonished that on another web site, a thread exists which states the owner of Sigma was photographing displayed Sigma SD-14 Booth Display prints at Photokina, with a Sony camera, for purposes of the poster showing all just how the SD-14 prints look like, with even a comment on the levels of graininess of the prints.
Does not Sigma have full size samples for media distribution at this time?
I hope they can deliver on their press release claims. As a people/rint guy, I would be tempted to switch.

It is a fact that most Bayer users out there just do not understand the Foveon concept at all.
And they just do not understand that Megapixels do not account for image quality. Here the Foveon sensor excels - it is common knowledge that this sensor's pixels are very clean compared to Bayer sensors (because of no guesswork) and it's images enlarge much better than a Bayer image.
This is also why Foveon images can be printed to huge sizes with astonishing results. It is also the only digital image which has been described by may as the closest to 35mm film and even approaching medium format results.
So forget Megapixels - it means nothing - the proof is in the pudding!

Max,
I hope you don't think the 12mp of the D2x or the 16mp of the 1Ds Mk II is uninterpolated! The D2x has 3 million R pixels, 6 million G pixels and 3 million B pixels. The 1Ds Mk II has 4 million R, 8 million G and 4 million B pixels. The Sigma has 4.7 million R pixels, 4.7 million G pixels and 4.7 million B pixels. Pretty close to the above two, I would say.
In all fairness though, the 3.4x3-megapixel SD9 and SD10 didn't actually produce a resolution rivalling 10mp Bayer cameras - more like 6mp ones. At least when photographing a high-contrast test chart. So I think the test results of the SD14 will be closer to those of 8-10mp Bayer cameras.
However, in real life there are low-contrast, high-detail subjects too, such as hair, foliage or grass, and this is one area where even the most advanced Bayer cameras are underperforming. With these subjects, the Foveon sensor technology has the upper hand, so I'd say for portrait and landscape photographers the SD14 might even be a better choice than the Canikon flagships. (Not to mention the complete lack of colour moiré!)

Zoltán, I hear what you're saying about the Bayer interpolation, but
not all interpolations are created equal. The Bayer CCD interpolates
color information, which is not nearly as important to the perceived
resolution as the intensity information interpolation of a Sigma CCD.

One advantage of the Foveon/SD system over Bayer cameras that is often overlooked is that raw file size for an image of more or less the same quality is much smaller (roughly 1/2). This is beneficial relative to data storage requirements and image processing time. One would also expect better signal to noise ratio due to the larger incident light capture area in the case of a Foveon sensor stack, but so far as I know this has yet to be demonstrated.

hi zoltan,
I take a file of a 8 mpixel lumix picture and get about 22 mbyte picture file out of it which fills 2xA4 I use in my books. every other methode below gives flat picture for this size -I tried it-. The next is I buy a canon eos 400 and have really enough pixels for this. the marketing people can turn it in any way they want, its wrong - its the pixels who give the detail and the more pixel the better the detail ! but in any case lets forget about this for the moment. with my sony stuff the other day I encountered all blue pictures in my dcr 2000vx -video-, sony repaired it without charges, but now I encounter the same stuff on a other sony I have a dsc-t9 cybershot. since this is a completly different thing I wonder, can someone give me a idea?

I've been intrigued by capabilities of a Foveon CMOS sensor since before Sigma started producing their SD9 camera.
When I learned that Foveon made a deal with Sigma, I was very unhappy. That meant that to use Foveon sensor I was limited to Sigma bodies and (what's more important) to using Sigma lenses. That, in turn, meant that I will probably never find out, because I will never buy a Sigma lens...

I own a Sigma SD9. What it does, it does very well but it has great limitis also.
The quality is very nice at 100 ISO. I was not very happy with the photos shot at 400 ISO. Battery life is not very good with the SD9. I will be very interested in the SD14 but I really wish they would offer it with other lens mount options.... ie Nikon and Canon.
Then I would consider it even more seriously since it could become a part of my overall interchangeable Nikon fleet!

I have a SD9 and had a Canon Digital Rebel. On copy stand work the Sigma was great. The Canon was OK. Out in the field shooting landscapes I liked the Canon. The canon was lighter, had longer battery life and the user interface was better. If I am shooting objects with fine detail I want the Sigma.
As a rule of thumb for resolution divide the Foveon mega pixels count by 3 and the Bayer filter camera’s by 2. So the SD14 should look about like a 9 mega pixel Bayer camera. The nice thing about the Foveon camera is that all three colors will have the same resolution. Bayer cameras have half the resolution in red and blue as in green. Because humans perceive green better then red or blue, the Bayer camera’s perceived resolution is the green resolution.

Charles, can you predict the quality of this camera based on your knowlege of the SD-9, and ideas about more pixels, this certainly looks like a work-horse!
Thanks!

Nick the answer is no, the sensor in the SD9 and SD10 has larger pixels then the SD14’s sensor (9.2 vs 7.8um). I would think this would lead to more noise. I do think the resolution will be higher, but there is so much more to image quality. I do have it in my budget to buy one, but not until I see some reviews.
