Complete D-SLR System Guide

With 10 companies offering D-SLRs today, there’s something for everyone

Like the K10D, the GX-10 is loaded with goodies: a 10.2-megapixel resolution, a body-integral anti-shake system (Samsung calls it OPS-Optical Picture Stabilization) that works with all lenses, a two-tier anti-dust system, a rugged body that's dustproof and weather-resistant, an attractive ergonomic design and lots more.

System Accessories:
All three Samsung D-SLRs will accept Pentax lenses, of which there are many. Samsung also offers a pair of Schneider D-Xenon lenses, an 18-55mm and a 50-200mm, for the GX-1 models (these lenses can be used on Pentax D-SLRs, too). GX-1 accessories include the External Flash SEF-PZF, a remote control, an AC adapter and a case. Additionally, a number of Pentax accessories can be used with the Samsung cameras, as well. The Samsung D-SLRs come with the Digimax Master CD, which allows users to download, view, edit and save RAW and JPEG images.


Sigma's new SD14 features a 4.6x3-megapixel version of the unique Foveon X3 image sensor. While conventionalimage sensors record data for just one primary color at each pixel site, interpolating the other color data for each site via complex algorithms, the Foveon sensor records data for all three primary colors—blue, green and red—at each pixel location. The result is much better image quality for a given horizontal-by-vertical pixel count (which is 2652 x 1768 pixels for the SD14). We haven't yet had a chance to try the SD14, but the images in the camera brochure (which were all shot at ISO 100 and focused and exposed manually) look terrific.

Camera-wise, the SD14 features a 2.5-inch LCD monitor, simplified controls for easy operation, a high-eyepoint pentaprism finder that shows 98 percent of the actual image area, a built-in flash unit and a built-in dust protector for the sensor that can be used or removed at a touch (and that sits far enough in front of the sensor that any dust that adheres to it will be so far out of focus as to not appear in images).

Previous Sigma D-SLRs shot only RAW images; the SD14 also will do JPEGs. And the Sigma Photo Pro 3 RAW image-processing software offers three processing modes to suit your needs: per camera settings, auto adjustment and custom.
