I also have the D7K on Pre-Order. The sensor and pixel size are very important, but there are other factors. The D7K comes with the new Xpeed 2 processor and the 2,016-pixel RGB (3D Color Matrix) sensor. Now days, it is all about firmware.
Nikon has yet to introduce a “dog” for a camera. However, there is always a first time and we know nothing about the D7K. The Chase Jarvis photos taken with the D7000 are just ridiculous, imho. His pictures are supposed to extol the virtues of the camera and he takes one of a cowboy in a cloud of dust! Unbelievable!!!
If the camera is a dog, I will return it - have plan “B” in place. I will go straight to the Leica X1. When Leica announced the X1, I just finished purchasing the D-Lux 4 and D5K. They are both gone, now. On the other hand, it would cost me ~ $2,500 for the X1, viewfinder and extra battery – ridiculous! The recently announced Fuji X100 is a better camera for less than half the price of the Leica. However, it is the Leica colors that I’m after and the X100 does not have them.
If I had ~$22,000 I would go after the M9 and three lenses, but I don’t. Therefore, the only Leica I will ever be able to afford is the X1. I really hope and pray that the D7K works out.
