I didn't want to insult any D3 owners here by saying that the latest generation of DX sensors outperform the D3 And I've never used a D3 myself, I was just relying on tests I've read online. Sensor technology has really come a long way.
I cannot be insulted at all.
My D3 is somewhat north of150.000 clicks and paid a lot of my bills since I bought her new in 2008.
The IQ of my D600 is better in most situations, but she is not as sturdy and dependable. The IQ and ISO performance of my D500 is superb, so the D3 is mostly a backup device today
