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 D800E has the larger sensor area. More area usually means greater light-gathering potential, though real image quality still depends on sensor architecture and generation.
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 D800E has the larger sensor area. The D800E has the lighter body. The D800E has the higher effective resolution. The D800E is the newer release. Also consider the lens system and subjects you shoot.
