On Friday I was allowed to use the D800, as the Institution I´m working at, is testing cameras (we need a lot of them for our photographers). The 5DMk3, we tested some days ago is very good, when you don´t have much light and you are not allowed to use an flashlight. But my heart stopped beating, when I saw the quality of the D800s pictures we took in the operating theatre, outside of the building (landsape,...) and shooting portraits. The quality is great! Really great! The product specialist of the selling company used lightroom to optimize the imagequality. But the result was amazing.
I took some pictures of flyinging birds around the builiding and landing helicopters. As the helicopters were approaching fast and I had just some seconds to take the shot, I can say, that the AF is very fast.
As I´m owning just Canon cameras, I´ll pray for an pedant from Canon (or an payable 7D MKII)
