Summary: I use Nikon D5100 and Nikon D800E with few f/1.2 and f/1.4 G. Nikon's and Sigma's sharpest Prime Lens, but I prefer the photos from this Sigma when shot out door, especially still life and landscapes.
Summary: I love its phenomenal image quality light years ahead of everything else. it is a king of all kings. I hate its retarded impotent deign. Where is your pride and ego, Sigma? Hire the best designers and electronics engineers in the world and make earth shattering killing compact camera - 1/2" thin...
Excerpt: Much has been written about this enigma of a camera. Many have criticised its slowness and lack of High ISO performance. That was when the camera was first released. The latest edition of the Sigma RAW conversion software version 6.03 seems to address all the noise issues.
I actually use this as my walk around camera and love everything it makes

Summary: It's not a camera for everyone, but if you are looking for something different, here it is. the IQ is incredible, the Quattro line is an improved version of the Merrill line. I actually use this as my walk around camera and love everything it makes.
Summary: Superb image quality. Search SIGMA DP2 on Flickr for examples. Also see It's big brother the SIGMA DP2 Merrill's examples. Both cameras easily yield astounding professional results when controls are mastered.
Summary: This small nondescript black box is no good in low light. After taking a shot, you need to wait 15 seconds before you can chimp (but you can continue shooting). So you need to use it like you use a film camera loaded with a roll of Kodachrome.
Excerpt: Camera Body and Screen First thing that strikes you is this is a small dense camera. It is beautifully built and feels like a step up from cameras of a similar size such as the Panasonic GF1. It's all metal besides the controls and lens casing, and feels solid and cool to the touch.
Summary: You will love this camera or hate it. I love it. I've realized, after reading reviews of each of the Sigma DP cameras and owning them all (DP1, DP2, DP1m, DP3m), that the negative reviews are mostly written by people who don't actually own the cameras.
Summary: Let me first clarify some concept regarding this camera (Sigma DP2 Quattro)...Since most of the reviews out there claims that this camera is awful for shooting photos in low light and at high ISOs (and maybe they are right).
