Digi Swap is a device that aims to breathe new life into old film cameras. It allows you to connect an iPhone to a still photography camera, so the phone uses the camera’s lens system. A bespoke app takes care of the image capture. According to the Digi Swap website, the system is currently only compatible with the Apple iPhone X, XS, 11, 11 Pro, 12, 12 Pro, 13 and 13 Pro.
