This is our standard studio scene comparison shot taken from exactly the same tripod position. Lighting: daylight simulation, >98% CRI. Crops are 100%. Ambient temperature was approximately 22°C (~72°F).
Apart from the D3X's significantly higher resolution once again the most obvious difference here is the 'per pixel' sharpness, which is simply superb on the D3X. The D3X default sharpening is higher than the D3 but again part of the difference appears to be due to a weaker AA filter on the D3X. As expected the D3X resolves a significantly higher amount of detail than its sister model, but color and tone characteristics are very similar.
