In our recent iPhone 6 Plus teardown, we dove deep into the new iSight camera, to get a look at what makes it so special. We found a complex array of electromechanical actuators that trigger the optical image stabilization, and got a peek at the sensor. But that's about as far as our technology took us. Enter our buddies at Chipworks, and their super-scopes. They've recently published some awesome images and expert analysis that should satisfy even the most ravenous technophile appetites.
For example, they found that the iPhone 6 Plus camera chip, fabricated by Sony, is a stacked (Exmor RS), back-illuminated CMOS image sensor (CIS) featuring 1.5 µm generation pixels. Their tools also let us see the much-touted "focus pixels"—pixels specifically tasked with checking focus and doubling the autofocus speed of this camera compared to its predecessor.
