“Our plans for the SD15 were originally shared with the photo community at photokina in 2008 because we wanted our customers to know that we’re committed to the SD camera system and our outstanding Foveon technology,” said Mark Amir-Hamzeh, general manager of Sigma Corporation of America. “It’s been long-awaited, for sure, but it’s worth the wait. We are really pleased with the image quality we’re getting from this camera.”

The Sigma SD15 uses the Foveon X3 direct image sensor. The SD15 also utilizes Sigma’s True II image processing engine, a new 77-segment AE sensor, large 3-inch LCD, improved user interface, and the SecureDigital (SD) media card for recording images. The camera also ships with Sigma’s Photo Pro (SPP) 4.0 software. Sigma has expanded the auto bracketing feature from three to five frames for added flexibility.

Other features include a 5 point AF, an added ISO stop of 3200 for a full ISO range of 50-3200, Analog Front End (AFE) and larger buffer than the previous model, the SD14. The SD15′s buffer allows for the shooting of 21 raw images continuously. The SD14 was only capable of shooting six raw images continuously.

The SD15 utilizes the Sigma SA bayonet mount for lenses. The camera features a diopter adjustment; single AF, continuous AF, and manual focus modes; eight white balance settings including custom; exposure compensation; X-sync at 1/180 of a second, hot shoe and sync terminal, manual pop-up built-in flash and S-TTL Auto Flash metering system. Compatible Sigma external flash units include the EF-530DG Super, EF-530DG ST, and EM-140 DG. Optional compatible accessories include a battery power grip, remote controller and cable release switch.

The SD15 is the latest in the company’s SD series of digital single lens reflex camera bodies to utilize the Foveon X3 direct image sensor. The 14MP Foveon X3 sensor captures all primary RGB colors at each pixel location arranged in three layers.
