I was not referring to phone lens, although those things are being applied there too. It is now possible to build a telephoto lens for your DSLR, that costs $2 to make, is short and flat, yet has better optics than your current kit. When these become common, it will likely cause another seismic shift in the pure-camera market. Perhaps some of them will actually be bonded with the sensors, unlike what we have today. Regardless, new lens technology -- while likely to make a greater impact on mobile phones -- is largely orthogonal to them.

  Metamaterial lenses seem to be the fusion power of photography. Just one breakthrough that might not happen before they're commercially viable.

> It is now possible to build a telephoto lens for your DSLR, that costs $2 to make, is short and flat, yet has better optics than your current kit. Do you have any references you can share? I'm super interested. edit: For anyone else interested, the key phrase that worked for me was "metasurface lenses".
