photo, html5: iPhone vs. "pro" camera

How does the iPhone hold up against a serious camera? | The Verge:

It's Fujifilm's X-T1 against the iPhone 5S in a showdown



Nice comparison, and example of using "split overlap images" effect

Strange that so far there are no "replace-able" lenses for smartphones.

Also strange that there are no more "SmartCameras", running apps, only Samsung's experiment.
