Having read many Reviews of cameras using the small 1/2.33 sensor (6 mm x 4.5 mm) it appears evident that beyond 12 MP both the low light performance and the resoluition suffer when more than 12 MP are crowded onto this smaall sensor. In almost all reviews of the 14-16 MP cameras based on the 1/2.33 sensor, reviewers comment that "noise reduction, even at base ISO, is blurring detail". And it would appear that this is not a limit imposed by technology, but by the laws of physics. When the pixel size gets down to about twice the wavelength of light, the only way to make real gians in resolution by increasing MP is to use a larger sensor. This would in turn necessitate a larger lens and heavier, much more expensive camera.
A lot of that noisecould be explained as congealed particles of bog turf dangling from the cow's hair.
