Summary: Anyone who pays attention to the compact camera market has had their eyes on the Sigma DP1 for some time now. Ever since the original prototype was unveiled back in 2006, fans have been clamoring over Sigma’s concept of taking a DSLR sensor and outfitting it for a pocket-size digital camera.
Excerpt: Sigma’s DP1 is unusual for a digital compact camera, in that it has an APS-C-size sensor, as found in many digital SLRs. Sigma has done an excellent job in keeping the DP1’s wide-angle 28mm equivalent lens small, but there’s a price to pay.
Pros: Large DSLR-like APS-C size Foveon sensor and high-quality 28mm f/4 wide-angle lens; compact dimensions; excellent picture quality at lower ISOs.
Cons: Noise levels higher than current crop of DSLRs; menu-driven operation for most features; poor battery life.
