Nokia's cameras don't do extra levels of optical zoom. Instead, they're all meant to capture a massive amount of data for HDR and depth based photography. The camera array was partially developed by Light, the company that also made the wild 16-lens L16 camera, and has recently announced a partnership to develop more computational photography products with Sony image sensors.

Light's initial 16-lens standalone camera vision was to offer up a Swiss army knife of options for any photo need. Light's L16 camera was reviewed to some disappointment when it debuted, but hinted at a multi-camera phone future. Light was expected to release a phone with nine cameras last year.
