We had Nikon came to the office to present the new D3, what a machine! Its such a beast!! Fast out of the box, fast paced shooting mode with vibrant colours! Last month we had Canon who came up with their EOS-1ds Mark III, these are superb machines and at that level the quality is unbelievable...the only downside is the price tag....:)

Also the D700 out at the end of the Month , Looks like another nice addition to the FX range  !

The d700 is full frame.... same sensor as the d3. 

The only difference between D700 and d3 is viever 95%/100% and cleaning system in D700 but if You want camera to studio it's not the best solution
