For me, the camera is the most important function of the iPhone, I sure hope the next iPhone has a f/1.7 optical setup or faster!!! I'm tired of f/2.2 and average image quality. Apple sure is SLOW at evolving their iPhone cameras, especially since they advertise so heavily about iPhone photography. As much as I despise android phones, the galaxy note 7 has a fantastic camera and if I have to switch just because of a camera, I'll be doing so with bitterness. But at least my iPhone 6s Plus is paid for an I can still use it for normal stuff and use the Samsung for the photos if I go that route. Sounds rediculas but if Apple doesn't deliver, that will be lame, they will be lame! I don't know what the purpose of a dual lens camera will be, the optics still look like they are f/2.2 (small lenses) from the leaked photos I've seen. The 4.7" iPhone 7 looked to have a larger camera housing, hopefully that will be f/1.4 or 1.7. I just hope apple does the same for the plus.
