Marcel Sauder, a freelancing photograph with plenty of experience, reported about the D3 here and for those of us not able to read German here is my translation:
“The D3 outshines everything I hold in my hands so far (Canon, Nikon, Pentax, Mamiya)!”
“I tested the following lenses and each of them is still top with the D3: 85/1.4, 50/1.4, 200/2.0, 70-200/2.8″
“Auto white balance is sensational and beats the pants off the D2X. Doing available light the D2X was disapointing but the D3 delivered”
“The new AF is able to detect colours and features a face/eye detection, the cam was able to follow the eyes/the face until you turn away. If you don’t want the feature you can turn it off “
