Apple to use bayonet-style mounts for interchangeable lenses on the iPhone 6?
The iPhone 6 might come with a "bayonet attachment mechanism", allowing users to easily snap interchangeable lenses on the back of their devices. This is suggested by a recent patent, granted to Apple today. The company touts that unlike similar "eyelets, hook, and loop fasteners", the described lens-holding mechanism does not deviate from Apple's aesthetics. In addition, Apple's bayonet mechanism is apparently configured to let go if you drop your iPhone, preventing any damage.
Apple's invention fits directly over what-seems-to-be a protruding iPhone camera unit. The coupling mechanism does not position itself via magnetic force, as it uses a more traditional approach – a set of tiny bezels around the camera unit allow users to gently screw the interchangeable lens.
As we already mentioned, although the bayonet mount fits perfectly in place, it will easily decouple itself if you drop your phone. This is ensured by the ramped surface of both the iPhone's camera unit and the interchangeable lens.
This concept falls in line with the recent rumors and leaks, which suggest that Apple's next iPhone might come with a protruding camera. We also heard that the upcoming flagship might come with a camera unit that supports swappable resin lenses. The iPhone 6 might also be the first Apple-branded device to sport OIS (optical image stabilization).
