It's the first five-rear-camera phone. But is that even a big distinction, now? The Samsung Galaxy S10 has three rear cameras (and four on the upcoming 5G version), and a total of six cameras inside and out of the Galaxy Fold.

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.
