Summary: The DP3 is a good camera for portrait. Owner should have a second camera to avoid frustration. Very bad at high ISO Have a small dynamic range (that's one reson for having a second camera). You should be prepare to light darker spots. Very easy to over saturate reds. Slow shutter.
Excerpt: I've never seen so ambigous reviews for a camera as for the dp Merrills. Therefore I was hesitating to get one. After using the dp3 for a few days I must say that I'm very happy with it. The key thing is that you use it for applications it fits.
Summary: Pretty much everything the others have said is true, in my experience. The things that make the DP's fun and challenging for some are exactly the things that make others crazy. It's completely understandable, if one were to randomly buy a DP camera without researching it.
Excerpt: It's a slow beast, but if you have the patience to use it right, the IQ is astonishing. Not higher than 400 ISO, however. I use it in the studio (because it SYNCs) and it because practically replaces a Hasselblad w/80mm.
Summary: Awesome awesome awesome camera! but this is more of an artists tool then a consumer camera. I must assume that if you're aware of the Sigma cameras and the Foven sensor, you know what you're getting into with slow processing and writing times, huge raw files, and horrible ISO performance past 400.
Summary: If you are willing to work at it, this camera will deliver phenomenal images. However, it will not deliver those images every time. You have to work at it. As far as "ease of use" goes, my cell phone tops this camera in the point and shoot category.
Excerpt: I got the Sigma "dp3m" after reading about its extremely good image quality. From the reviews I gathered that the camera was not very good otherwise, and this is in a sense true, but my experience has been all-round positive.
Summary: Pros * with sufficient light, it takes outstanding photographs * the detail is incredible * light weight Cons * lousy battery life Note 1: It's not a consumer-friendly point-and-shoot, nor an action photographer's dream.
