Yes.. 4S = 8 MP. iPhone 5 = 8 MP with some "enhancements". iPhone 5S = 8MP with some "enhancements".
iPhone 6 = 8MP with "enhancements"??
I know megapixels aren't everything, but good luck telling the masses that the camera is really improving if you try that again.
iPhone 5S camera ACTUALLY is better than iPhone 5 camera in almost every aspects.
It's not just marketing ....
Megapixels aren't anything, above 5-6 Mpixel. Sensor dimensions, aperture, lenses are way more important.
