>>4411928>is the sensor also housed in the lens module?Of course, it's just a p&s minus the user interface. It's been done before, like the sony qx100. The improvements appear to be the magnetic attachment and the optical data transfer. Both of which mean you have to buy a new phone to use with it.
None of these improvements address the core problem of this design, which is that you could just buy a real camera instead of yet another stupid dongle for your phone that will become ewaste in 6 months when they drop support for the app.
