iPhone cameras: Apple is researching novel lens systems with periscope technology

Slowly but surely, Apple and other smartphone manufacturers are reaching the limits of what is technically possible with conventional means with the cameras of the devices. Both in Cupertino and elsewhere, people are therefore thinking intensively about innovative solutions, for example new types of periscope systems. Among other things, these would make it possible to reduce the number of lenses commonly used today from three or even four to just one or two, to construct stepless zoom cameras and to save space in the housing.
