I thought my understanding of the iPhone 7 plus camera at present was pretty clear but now that I have it I'm not so sure..... PS Sorry for posting a same question, if this is already covered please link me and I'll happily move over there. So my understanding was that at 1x - 1.9x this was a digital zoom provided by the standard lense of the camera. 2x was done by the telephoto lense and 2.1x - 10x was a digital zoom done by the telephoto. I tried to find ANY documentation with a clear explanation of what exactly each camera is performing but alas,apple in their typical vague nature has provide little documentation. With some simple tests covering each lens I can't see when the second (inside) lens is ever used. Even assuming some software magic is done, I can't see any diffrence covering the lens, 2x vs uncovered. This is using as macro of a subject as i can find (a dog hair). Thoughs?
