Sigma Corp. has introduced a successor to the SD14. The SD15 camera incorporates a 14-megapixel Foveon X3 sensor and a 3-inch, 460k-dot LCD screen.

With the X3 sensor, the SD15 can capture all primary RGB colors at every pixel location. Using three levels of photo detectors, the SD15 is able to more accurately reproduce color and offer a sharper image resolution. Up to 21 frames can be captured continuously in RAW mode, thanks to the camera's buffer memory size, which is nearly twice as large as the SD14. Contact-view mode makes it easy for users to view nine thumbnails at once on the 3-inch TFT color LCD monitor.

The SD15 can be used with over 45 Sigma lenses and a variety of flash accessories. The body-only configuration retails for $989.
