A few years back, I decided to ditch my trusty DSLR and take an entirely different approach to digital photography.
I wanted something that didn t feel like a chore to haul around but could still take respectable images.
I ended up going with a micro four thirds system and haven t looked back although recent developments at Harvard may one day change my mind.
Researchers there have developed a lens built of transparent quartz that s coated with millions of microscopic titanium dioxide towers arranged in specific patterns to focus light.
The end result is that light focused through a 600nm metalens can achieve the same resolution and magnification as a traditional 5-6cm glass lens.
Assuming everything pans out, we could see smartphones with DSLR-quality cameras arrive sooner than we think.
