New Sigma SD1 Merrill Foveon-Based DSLR

Sigma is reintroducing a renamed version of its previously announced 46MP, Foveon-based flagship DSLR, the Sigma SD1. Now called the Sigma SD1 Merrill after the late inventor of the Foveon chip—Richard “Dick” Merrill—the new camera is virtually unchanged except for the name and its present selling price, which at $2,299.00 (at B&H), is thousands of dollars less than its original selling price.
Like its original incarnation, the SD1 Merrill is designed around a unique Foveon imaging sensor. Unlike conventional CCD and CMOS imaging sensors, it records RGB channels through each pixel as opposed to the traditional 1-pixel, 1-color channel methodology used in conventional CCD and CMOS imaging sensors. As a result, Sigma refers to the SD1 Merrill’s APS-C format imaging sensor as its 46MP “True II Image processing engine.”
The newly named camera is compatible with all Sigma SA-mount optics and can capture stills in the form of JPEG or RAW files at continuous burst rates of up to five frames per second at full resolution. Other features found on the Sigma SD1 Merrill include a TTL phase difference detection AF system, a 77-segment metering system, a pentaprism finder with approximately 98% image viewing, a top ISO of 6400, and a 3.0", 460k-dot LCD.
