The Sigma DP family of compact cameras today got an exciting new addition. The Sigma DP3 Merrill is mostly identical to its siblings the DP1 & DP2 Merrill except for one important part, the lens. It features a 50mm (75mm equivalent) F2.8 macro lens. It has a minimum focus distance of 22.6cm resulting in a 1:3 magnification. The focal length makes the camera very suitable for portrait photography.
