One of the iPhone 7 's big selling points is its new camera. Apple upgraded the phone's back camera to 12 megapixels, with a larger f/1.8 aperture lens for capturing more light in your shots. On the front, it has a 7-megapixel camera, up from five in last year's model.But if taking photos is one of the most important things you do with your phone, then you want to know for sure: Is the iPhone 7's camera really the best one out there?
