The Sigma DP2X is mostly gets compared to pro digicams and mirrorless. The Sigma DP2X's top rivals come from Canon (such as the PowerShot S120) and Sony (such as the Alpha NEX-6)

Competitor classes

compared toPro digicam competitors

Generally, some of the advantages of the Sigma DP2X compared to pro digicam competitors include: it has a much larger sensor (sigma x3 20.7x13.8mm vs 1/1.8" 7.49x5.52mm), has a slightly wider wide angle lens (24 mm vs 28 mm), has a CMOS-family sensor (CMOS vs CCD) and supports an external flash.

However, on average it has a slightly narrower aperture (f/2.8 vs f/1.8), has a slightly smaller screen (2.5" vs 3"), has a much lower resolution screen (230k dots vs 1,230k dots), is much larger (mid size (113×60×56 mm) vs compact (100×59×29 mm)) and doesn't have image stabilization (none vs lens).
