Sigma DP-1 Merrill

Sigma DP Merrill Introduction

The Sigma DP-1, DP-2, DP-3 Merrill are an unusual offering in the prosumer point-and-shoot market. There are three variants of the DP Merrill, all with the same 14.75 X 3 megapixel Foveon “true color” sensor:

Focal lengths above are field-of-view equivalent for full frame; actual focal lengths are 19mm, 30mm, 50mm, nominal figures. Depending on actual focal length and precise sensor size, the above nominal figures are actually closer to 29mm, 46mm, 76mm (multiplier of 35.9 / 23.5 = 1.527).

Sigma calls the DP Merrill a 45 megapixel camera due to its 14.75 X 3 sensor, but finished RGB images are 4704 X 3136 pixels, or 14.75 megapixels at 88.6 MB for a finished 16-bit TIF.
