The iPhone 7 Plus has two back cameras, but the lens field in EXIF has six different values:




  • iPhone 7 Plus back camera 3.99mm f/1.8

  • iPhone 7 Plus back camera 6.6mm f/2.8

  • iPhone 7 Plus back dual camera 3.99mm f/1.8

  • iPhone 7 Plus back dual camera 6.6mm f/2.8

  • iPhone 7 Plus back iSight Duo camera 6.6mm f/2.8
