Telephoto and low light Also, the camera, lenses, and sensors don't all update every year. Early on in Apple's tick-tock approach to design iteration, camera updates were the "s" models ("tock") in release cycle. Now they seem to be just incrementing the number and you have to pay attention to what if any changes they make. This time they did 4x pixels and do pixel binning for regular shots and low light.
