Typically on the dual camera iPhones, AFAIK the telephoto lens is used for taking Portrait Mode photos. This is the case with my iPhone 7 Plus at least. This will no longer be the case for the iPhone XR. Does it matter? With traditional portrait lenses, you're better off with a mid telephoto, but that's because of perspective and distance, and the way the lens needs to be set up to get the appropriate bokeh. A lot of this no longer applies anymore with this computationally derived Portrait Mode. Still, I wonder what affect this will have on the perspective of Portrait Mode on the XR. I guess one just needs to remember not to get too close to the subject. OTOH, one annoyance I had with the 7 Plus, is if wanted to take a 2-person portrait mode shot with some background, I sometimes couldn't easily fit everything in the frame due to the telephoto lens. This problem would be solved with the XR's wide-angle Portrait Mode. How do you think a wide angle Portrait Mode will affect things? What are the results on other single-lens camera phones with similar portrait modes?
