I've had the D-300 for several months now. First; it is a wonderful camera in many ways..perhaps one of the best in the APS-C sensor arena. I am somewhat disappointed in it's low light ISO performance even at ISO 400-800. I know it's an improvement over the D-200 in sensor design, but still, it seems this sensor will not produce professional quality images at even ISO 400. Here's a sample I shot with the SB-600 and simply dragges the shutter a little. Personally, for me, it's unusable. I wonder if anyone has feels the same? Comments that you should have bought a 700 or D3 are forgone conclusions.
