So, what exactly was used? According to AppleInsider, two iPhone 5s’ were mounted onto $75 BeastGrip lens adaptors that allowed them to use threaded lenses, including the $38 Neewer 0.3X Baby Death 37mm Fisheye Lens, as well as a Schneider iPro lens, which you can buy in a kit for $230. Oh! I almost forgot — they also used one of Freefly’s $5,000 MōVI M5 gimbal stabilizers for all of those beautiful handheld shots. As far as software goes, the “fast and dirty” edits were made using iMovie, while the $5 FilMic Pro was used to offer more control over their cameras — it’s kind of like the Camera+ for video.
