Andy - I don't remember where exactly, but I know I have seen something like this online in one of the forums either here, or DPReview etc, in the last day or two. It compared the D2x, D3 and D300 at ISOs of 100 and 200. My take on results were basically, they were all quite close in sharpness and detail. This was kind of expected due to similar Mp ratings. The D2x has a slightly warmer cast to the image compared to the newer cameras, some might argue the D3 had more tonal range, but for my money the D300 seemed to be the equal or better. You cannot judge too much by these jpegs on a monitor for sure, but it was an apples to apples test and given the testing was done by a regular forum member, should be above reproach. THe end result I had no regrets going for the D300 for me, it gives similar image quality or better in a small package. Combined also with the improvements in on board image processing etc, and this was a good thing. Do not know if I would upgrade to a newer camera unless I really needed better high ISO quality. Also for much of what I do I do not need FF at the moment, also I have been considering the D3 for the other reasons, namely, high ISO and high frame rates for shooting high school basketball, without flash, but my D300 is doing better then any camera I have owned before. ....Keep looking the thread is out there, if I find it will post the link.....Good luck and good shooting..Don
