I don't know which is the best camera, and although image quality isn't everything if I thought that the Pentax produced the best image quality I'd probably have placed it at number 1 and provided reasons why the others could be good buys too, if I thought that they could be.

Taking things to an extreme, for example, Nikon D700 Vs Camera phone. The Nikon is the best camera but I want to carry it in by back pocket so I'm placing the camera phone at No.1. There's a part of me that see's the logic in that decision but there's a part of me that wants to put the Nikon at No.1 because it's clearly the best camera and then still make a personal choice to go for the camera phone.

I don't have a problem with someone placing the camera which produced the best image quality last, I just find the concept intriguing. But none of this would stop me buying an Olympus if I wanted one.
