Good read....thanks for sharing this insight. I don't get too excited about any more, but originally had some concerns, because of the larger sensor and higher resolution. I am just watchful and quick to clean and make an effort to pay attention during post processing. It is very interesting that with certain image presets such as conversion to B&W or using more detailed tools of CS5 and/or Nik Software that I will see instances of dust that I might not have seen in the original image. It is just a fact of live with more resolution the more we will see it sometimes.
