This may look out of place on a list of iconic cameras, but just as the Kodak Brownie was instrumental in the democratisation of photography in the early 20^th century, so the iPhone drove its own, entirely digital revolution. Indeed it’s arguably the most important camera of this century so far. Where the Brownie allowed anyone to take photographs, the iPhone opened up the process to a hitherto unimagined degree. Freed from the need to print, it enabled users to share photographs instantly with anyone else in the world, thanks to social media apps such as Facebook and Instagram. But this could be achieved using a small, slim device that slipped easily into a shirt pocket or handbag. It decimated the point-and- shoot camera market in a matter of years.
