I can sympathize with the seller, although I
personally wouldn't give up a G-series because I have my iPhone. The best camera is the one that's with you, and my iPhone is always there. Not only that, but the device is location-aware, I can post-process the photos right there, and I can publish them
anywhere at that very instant. I much prefer a proper camera's output quality and ergonomics, but the great convenience the iPhone camera offers makes it, quite simply, fun and viable.
For example, this picture isn't a work of art. They seldom are from the iPhone. But it's satisfying. Time was effectively stopped, and that beautiful instance was preserved by the device.
