Apple's granted patents and patent applications over the last couple of months have revealed a significant interest in camera lens systems that attach to the iPhone's existing camera, enhancing its photo taking capabilities much like third-party lens attachment solutions from companies like Olloclip.

In a newly published patent application (via Patently Apple), Apple explores a bayonet lens attachment mechanism to fix a separate lens to an iPhone. Bayonet is a type of pin-based of lens mount that is designed to precisely align the mechanical and electrical features between a lens and a body in a traditional camera, preventing the components from rotating.

According to Apple, this attachment method is superior to other solutions such as a separate case that lenses can be mounted to or a magnetic attachment system that may not be strong enough to keep a lens attached while in motion. Apple describes both a case and a magnetic mount as "undesirable" and "unsightly."

Attachment mechanisms are provided. The attachment mechanisms may be configured to couple accessory devices, such as lens devices to an electronic device. For example, a lens may be coupled to the exterior of an electronic device with first and second attachment mechanisms.



The application explains in detail how a lens can be mounted to an iPhone or other device through a bayonet attachment, with the iPhone or other device possessing a cavity that the can attach to a lens and the bayonets being located around the aperture of the lens. It also describes quick release methods, should a device with a lens attached by dropped or otherwise damaged.

While there are a range of third-party add-on lenses for the iPhone and the iPad, none of the available solutions are able to use an attachment method as Apple describes due to the fact that such a system would have to be manufactured directly into the iPhone. Instead, they use magnets, cases, or other less than ideal attachment solutions that would be unable to compete with a native solution from Apple, should the company choose to pursue camera enhancements in the form of lens attachments.

Apple has also explored other attachment methods in recent years, including a magnetic lens attachment system that was detailed in a patent granted in January and a similar lens attachment system that worked with a removable back panel used to swap in different lenses , unveiled in 2012
