DxOMark

DxO Mark proclaims that it's a website for people who are passionate about image quality. It's still in beta version, and it "features the first database of objective digital camera image quality measurements entirely accessible via the internet."

In addition to the Image Quality Database itself, the website proposes its new DxOMark Sensor scale, which allows it to rank digital camera with a single number for photographers to evaluate and compare models.

Certainly an interesting concept, and quite useful for buyers when confronted with the myriad of camera choices. Being interested in the new Canon 5D Mark II, I'll be keen to have a look at DxO Mark's measurements when these are published.
