DxO, known primarily for its image processing software has got into the hardware business. For years we’ve been seeing a variety of bolt-on/clip-on/glue-on lenses for the iPhone. The DxO One instead plugs into the iPhone and iPad through the lightening port. The lens housing is in the unit and is s significant upgrade to the current iPhone 6 camera (or anything we’ll see in the iPhone 6s). There is a 20 Megapixel, one inch sensor, and an F Stop down to 1.8. All of this adds up to better low light performance, better depth of field, and just generally better pictures at a cost of $600 and an additional thing to carry around.
