People used heavy film cameras, awful lenses, rusty shutters amidst a raging war to take incredible pictures (Magnum photographers). If they had iPhone cameras back 50 years ago, they'd kill to get such a small camera system in their pockets.
Good photography (and cinematography) is largely a conceptual thing - put the right brain behind the tools, however limited, and they'll produce incredible content. This is hardly surprising. It is the Jimmy Hendrix equivalent of using an eBay cheapie to shred incredible music. Or look up Robert Rodriguez's El Mariachi film shot with a total budget of $7000. No shit!
