Per BMX. this is so. His comment implied that in order to get the instant shutter performance they chose to only write 5 MP images.
Has anyone heard if it is only a 5mp sensor, or are they using a larger sensor and only "using" 5mp to keep the instant shutter speed up to par? If it is a larger sensor, maybe same as GSII, I wonder if someone could change the option for instant shutter?
We need ifixit to tear one apart so we can see what is going on inside...
