Jeff Pu said that the camera specifications of the next-generation iPhone, dubbed iPhone 6S, will stay the same as the current iPhone 6 at 8-megapixels, limiting potential catalysts to push [Apple lens supplier] Largan’s stock price higher in the second half of the year.
Pu’s reasoning–that limited supplies of higher-resolution CMOS sensors have lead Apple to make the decision–seems somewhat spurious for a company renowned for its supply chain management, but the idea isn’t an unreasonable one.
While those who know little about photography may buy on numbers, cramming more megapixels into a small sensor can actually hurt image quality. One of the key reasons the iPhone camera is so good is that Apple uses a relatively large sensor with a low pixel density, an approach which is particularly beneficial in low-light photography. The iPhone 6 and iPhone 6 Plus cameras were ranked joint 1st in the highly-respected DxOMark mobile tests.
