microfresnel lens at phones does wide angle and regular simultaneously

Someone asked why not use a wide angle lens (possibly like a clip on) instead of a Selfie stick. You can do both. I know about the lytra, which if modified would likely work. Another way to do it is to have a fresnel lens (or one of the new waveguide lenses) with grooves that are at slightly different angles. the software figures out which image is which, a little like TV interlacing. Doing this at higher than human visual resolution seems very possible, as there are probably 100 MP cameras now.
