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.
