The S6400 was announced 3 years later than the A900 and that is quite a significant gap as far as technology is concerned. Each of these cameras feature different body design with the Nikon S6400 being a Ultracompact camera and the Sony A900 being a Mid-size SLR camera.

Before getting straight to a full comparison, here is a simple introduction of how the S6400 scores against the A900 with regards to portability, imaging, features and an overall rating.

The following is a sample of the gallery pics for Nikon Coolpix S6400 and Sony Alpha DSLR-A900. The whole galleries are viewable at Nikon S6400 Gallery and Sony A900 Gallery.

Typically, it is very tough to visualize the contrast between sensor sizing merely by looking at a spec sheet. The visual here should provide you a clearer sense of the sensor sizing in the S6400 and A900.

Clearly, each of the cameras feature different megapixel count and different sensor sizing. The S6400 with its tinier sensor is going to make shooting shallower DOF trickier and the Sony A900 will resolve more detail with its extra 9 Megapixels. Greater resolution will make it easier to crop pics way more aggressively. The fresher S6400 should have an edge in sensor innovation.
