Reasons to choose D3s
Released in 2009, D3s has about 860 mm² of sensor area, 12.1 MP effective resolution, and a 1,240 g body. Use these values to narrow the field, not as an overall image-quality score.


The D3s and D4 have the same sensor area. Compare pixel density, sensor architecture, and release generation to understand likely image-quality differences.
These cameras were released 3 years apart. Consider sensor generation when comparing pixel metrics.
Amber marks the value that is generally preferable in this comparison context. It is not an overall camera score.
The D3s and D4 have the same sensor area. The D3s has the lighter body. The D4 has the higher effective resolution. The D4 is the newer release. Also consider the lens system and subjects you shoot.
