With all three models, the iPhone X, iPhone 8 and iPhone 8 Plus unveiled, let us see to what extent Apple improved the optics of these mobile computing marvels.

The iPhone X is rocking a dual-camera lens, but it is vertically mounted instead of the horizontally mounted set up on the iPhone 8 Plus. The iPhone 8 still features a single lens, and gets the least amount of love from the company though that does not mean it is not a worthy addition for a smartphone upgrade.
