Camera Overview — Sigma DP3 Merrill

The Sigma DP3 Merrill is a fixed-lens compact camera built around a 46MP APS-C sensor, processed by a Dual TRUE II Image Processing Engine. Aimed at photographers who want serious imaging capability in a compact body, the DP3 Merrill packs a surprising amount of resolution into its metal chassis, which measures 121.5 x 66.7 x 80.6 mm and weighs 400g. The camera shoots both RAW and JPEG, giving users flexibility in their post-processing workflow.

Its ISO range runs from 100 to 6400, covering a reasonable spread of lighting conditions. On the back, a 3.0-inch TFT LCD with 920,000 dots of resolution serves as the primary composition and review tool, as no viewfinder is specified. Autofocus is handled via contrast detection, and manual focus is also available.

Storage is handled by SD and SDHC cards, and the camera connects to a computer via USB. Burst shooting is supported at up to 4 frames per second. Video capture is available at up to 30fps in 8-bit with a Standard color profile.

The metal body has no weather sealing, and the camera does not include Wi-Fi or Bluetooth connectivity. Battery life is rated at approximately 100–150 shots per charge using a Lithium-Ion battery.
