In this installment of yet another we-just-made-it-up series called “Nail in the Coffin,” we recognize our limitations – and then go on to ignore them.
When you have a hammer, everything looks like a nail. When you have Apple on the brain like I do, almost everything looks like it can be used by Apple to disrupt…something. Except in this case, maybe, it’s really true: a “wafer thin” flat lens that obviates the need for curved glass? Sounds like just the thing for an iPhone internal zoom lens.
None of us at planet5D have any idea what the practical limitations of this technology are, but we do know this: one of the keys to Apple supplanting traditional cameras is upping their game in optics, and this looks like a game-upper.
Yeah, OK, it also looks like a way to make ILC mirrorless optics even smaller and lighter too — and with fewer lenses in their systems than Canon or Nikon, it might be less costly to for Sony, Panasonic, Olympus, or Fuji to make the transition.
Either way, this flat lens technology from Harvard feels like another nail in the coffin of what are now considered traditional video DSLRs.

This New Flat Lens May Revolutionize the Lens Industry
When it comes to optical technology, or more specifically lenses, sharpness is the name of the game. In fact, accurate sharpness in terms of color reproduction is typically how you can discern a good lens from a bad one.
Poor lenses typically suffer from a phenomenon called chromatic aberration, where colors are distorted due to different wavelengths. Chromatic aberration is usually identified by “purple fringing” in an image’s areas of contrast and it can be pretty annoying if you are trying to get a clean and crisp image.
Newer lenses have their optics designed to minimize chromatic aberration, whereas older lenses tend to feature more color distortions. However, no matter what lens manufacturers do, they will always have to deal with color distortion if they are using curved lenses. But what if lenses weren’t curved?
This was the question proposed to a team of Harvard physicists who have successfully created a wafer-thin lens that uses only flat glass elements. The lens pushes the boundaries of what is physically possible in optics.
