Sigma SD14


Sigma's latest D-SLR delivers better color and performance

First Look: Sigma SD14

The 2.5-inch LCD has a large, bright screen for reviewing images. It also offers access to the improved menu system, making it easier to navigate through often-used camera features and controls.

5)
Eyeglass wearers will appreciate the redesigned pentaprism, which provides 98% coverage with a generous eyepoint of 18mm. The viewfinder also features a built-in diopter with a range of -3 to +1.5 to customize the viewfinder to your eyes.

6)
With three different metering modes (8-segment Evaluative, Center-Area and Center-Weighted Average), the SD14 provides the versatility needed to ensure accurate exposures under a wide variety of lighting conditions.

7) For photographers who enjoy macro photography, night scenes or use super-telephoto lenses, the inclusion of mirror lock-up is a big plus. This simple feature helps ensure sharp pictures at slower shutter speeds when the camera is susceptible to camera vibration during exposure.

8)
The camera's built-in flash offers convenience and generous coverage for focal lengths as wide as 17mm (28mm/35mm equivalent). The camera's S-TTL metering system helps to deliver accurate flash exposure, whether the flash is used as a primary light source or as fill.

Tricks Of The Trade:
The Foveon X3 sensor is based on a unique tri-layered sensor—the pixels of each layer capture the red, green and blue spectrum. All other sensors use the Bayer pattern, where a photosite captures only one color (R, G, B) and must have complete color interpolation in order to have a full-color image. The SD14 dedicates each layer to a specific color, eliminating the need for interpolation to achieve accurate color. While an anti-aliasing (blurring) filter is needed for a Bayer pattern sensor, none is needed for the Foveon sensor, resulting in a cleaner, better-resolved image for each pixel. Therefore, according to Foveon, the resolution of the camera isn't strictly based on actual photosites, but on the combination of each layer (2652 x 1768 x 3), for a rated resolution of 14.1 megapixels.
