Released in 2004, Dynax 7D has about 369 mm² of sensor area, 6.31 MP effective resolution, and a 760 g body. Use these values to narrow the field, not as an overall image-quality score.


The D40 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 2 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.
