Looks like a very clever feat. Really impressed.

But grumpy-old-me would immediately point out to the much smarter than I engineers that developed this prototype there has been a very stupid reason why (traditional) camera makers have not been using magnetically-only attach mechanisms to fix lenses on a camera body.

Quality lenses can be very expensive—and I have very little doubt that lenses that come with their own integrated sensor and are operated through a micro proprietary laser beam thingy, will also be very expensive—and as rudimentary as it is a locking mechanism, unlike tiny magnets, will made pretty sure the lens won't ever fall off the camera and end its live on the ground in tiny very expensive shreds of high-tech splattered all over the place.

Sure, one could easily add a locking mechanism on the lens and on the phone but wouldn't that go against the Unquestionable True Religion that says You Shall not Use Fat Phones—because fuck practicality, thin design is what's it's all about. Just askin' ;)
