Nikon introduced the new D700 SLR, their second digital camera with an FX format CMOS image sensor. The sensor is 23.9 x 36mm, almost the same size as 35mm film camera.
Why do photographers want a 35mm film sized sensor? The lenses on the FX format cameras don’t have the 1.5x crop factor of the DX sensor cameras, so you can spend a lot more money getting wide angle lenses. For example, this AF NIKKOR 14mm f/2.8D ED lens on the D700 is going to be the equivalent of a 21mm lens on a DX format sensor camera.
Priced at $2,999.95 USD, the Nikon D700 is a little more attainable than the Nikon D3 at $4,999.95 USD, I guess.
With all the improvements over a few short years, the Nikon D700 is at least 10 times better than my D70.
