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.
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.
Summary: As someone who prefers film cameras, but is addicted to digital editing, this camera seemed like a good fit. It is, but you need patience, a lot of patience, and buy a couple of more batteries. I also recommend buying a protective camera case. This camera does not feel like it can take a beating.
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.
