Sigma's SD1 DSLR Has 46 Megapixels, Kind Of

Now, I’ll be the first to admit that the Foveon sensor has its advantages, but I’m not sure the fact that your sensor has three layers means you get to triple the number of megapixels the camera “has.” I guess it technically does have all those pixels, but the output image will still be around 15 megapixels. Kind of a conundrum.

In any case, 15 is enough, and you’re guaranteed some serious image quality with that layered sensor. What else has this thing got for us?

Well, for such a long press release, there really isn’t a lot of information. It’s got a magnesium, weather-sealed body, 11 autofocus points, and it saves to CF type I cards. A 3″ LCD at 480×320 rounds out the package (I’m guessing they mean 460,000 dots, not pixels).

Not a bad camera by any stretch of the imagination, though they seem to be leaning very heavily on that sensor. A high-res LCD and large ISO range are really requisite these days for a camera to be competitive, from the sub-$1000 level to around $3000, at which point specialization kind of takes over. Since we don’t have a price or release date yet, it’s hard to judge where this thing lands. We’ll keep you posted, though.

Sigma SD1 Press Release

The Sigma Corporation is pleased to announce the new SIGMA SD1 Digital SLR Camera, incorporating a 46 megapixel (4,800×3,200×3 layers) 24×16mm APS-C X3 direct image sensor.

The SIGMA SD1 is Sigma’s flagship digital SLR model, adopting a lightweight yet solid magnesium alloy for its body and O-ring sealing connections to make a weather-resistant design throughout for use in harsh conditions.

The SIGMA SD1 incorporates a 24×16mm APS-C X3 direct image sensor and dual “TRUE (Three-layer Responsive Ultimate Engine) II ”image processing engines. The combination of the 46 megapixel (4,800×3,200×3 layers) sensor and dual TRUE II processing engines ensure the high resolution images are processed quickly with high definition and a smooth and subtle graduation of color.

The SD1 is SIGMA’s latest digital SLR camera which meets high requirements of professional and enthusiast photographers for all types of photography.

This product is showcased at Photokina 2010 in Koln, Germany.

46 megapixel 24×16mm APS-C X3 Full-color image sensor

The 46 megapixel (4,800×3,200×3 layers) 24×16mm APS-C X3 direct image sensor featured in the Sigma SD1 captures all primary RGB colors at each and every pixel location, ensuring the capture of full and complete color. Using three silicon-embedded layers of photo detectors, stacked vertically 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. Since color moire is not generated, the use of a low-pass filter is not required, meaning light and color, generated by the 46 megapixel APS-C X3 direct image sensor is captured with a three-dimensional feel.

Dual TRUE II image processing engine

The SD1 incorporates a dual “TRUE (Three-layer Responsive Ultimate Engine) II” image processing engine which improves the processing speed and overall quality of the final image. The unique image-processing algorithm provides high resolution power and reproduces high definition images with richly graduated tones.

CF card

The SD1 adopts the TYPE I CF Card. This camera is compatible with the UDMA enabling fast processing of large amounts of data.
* It is not possible to use Microdrives and TYPE II CF cards.

11 point twin cross sensor

The autofocus system features an 11 point twin cross sensor. The shifted twin cross type sensor improves AF accuracy.

Magnesium body

The Sigma SD1 adopts a lightweight yet solid magnesium alloy body designed to withstand rough use and shocks in harsh conditions.

Weather-resistant design

Buttons and connections benefit from O-ring sealing connections to prevent dust and water getting inside the camera body.

Large, highly visible 3.0” TFT color LCD Monitor

The SD1 camera features a 3.0 inch TFT color monitor. This 460,000 pixel resolution LCD monitor benefits from a wide viewing angle, making it easy to check focusing and composition.

Optional lenses

The SD1 can be used with over 40 Sigma lenses such as ultra-wide, ultra-telephoto, macro and fisheyes which adopt the latest technology such as the FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, SLD glass, Aspherical lenses, Sigma’s own unique Optical Stabilizer function, Hyper Sonic Motor and Sigma’s Super Multi Layer Coating. They meet the various and demanding requirements of all types of photographers.
