your writeup is a bit misleading when you refer to the "(probably unnecessary) 14 megapixel Foveon X3 sensor". you need to understand the Foveon sensor before making assumptions about it. even though it is a 14 megapixel sensor, it does not output 14 megapixel files. the 14 megapixels are spread across 4 layers (as opposed to one layer in a traditional sensor), thus it only outputs 4.7 megapixel files. so think of it as a very very accurate 4.7 megapixel camera, and then you realize that the 14 megapixel sensor is not only necessary, but its very possibly rather inadequate for professional use.

"the 14 megapixels are spread across 4 layers (as opposed to one layer in a traditional sensor), thus it only outputs 4.7 megapixel files."

14/4 = 3.5

14/3 = 4.7

Sheesh. Am I right or is this something way more complicated than that?
