iPhone7+ 56mm equiv "portrait mode"
I considered switching from Samsung and picking up an iPhone7+ just for the 56mm equivalent camera's field of view. I assumed the "portrait mode" would be pretty awful in implementation. As it turns out, sometimes it is. But sometimes, it's not so bad.
For the discerning photographer, I don't think this will enter their arsenal as it can't be relied upon (yet?) but for the average iPhone buyer, I think they'll be incredibly happy with it.
The longer a thread, the more likely that someone mentions Henri Cartier-Bresson or Ansel Adams.
