Fantastic work! Looked at the pencil sharpener too.

That is a well-thought concept. I especially like the idea to attach the components to the lens and the camera itself to the smartphone magnetically, like a Mag-Safe charger to a laptop.

But here’s the question:

Since the camera lens is not connected hardware-wise to the phone - how will the data (pictures) be transferred to the phone? I estimate the phone’s display will be served as the viewfinder and the pictures will be stored in the phones flash drive. I could imagine that the camera lens will be connected via bluetooth, but wouldn’t it result in a too low data transfer rate? When I transfer pictures from my phone to my laptop via bluetooth it takes several seconds per picture. An alternative Idea regarding the data transfer I could think of is to attach a cable from the lens to the charging port.
