The new iPhones are already very capable cameras. Thanks to the FusionLens 2.0 lens system, you can do even more on your smartphone. This clip-on device allows you to take immersive selfies and shoot super-wide anamorphic video in 23:9 right on your phone.
You can switch between your cameras quickly and operate both cameras to capture 360 images. FusionLens has an upgradeable mount, so you can use it with future iPhones. Expected to ship in March. You can order yours here.
