DxOMark review for the Nikon D3X
Key sensor characteristicsThe Nikon D3X features a very high resolution full-frame format CMOS sensor with 24.6Mpix. The D3X and the Sony A900 are the only two cameras at that level of resolution within the professional D-SLR category, but the D3X features a 14-bit Analog/Digital (A/D) converter which, as shown below, plays a significant role in boosting its capture performance when compared to the Sony A900 (with only a 12-bit A/D converter).The D3X’s lower ISO setting (down to ISO 78) compared to other Nikons certainly help as some dxomark metrics such as dynamic range are considered at lowest
