One of the big new features of the iPhone 7 is an all new camera system. The iPhone 7 camera includes optical image stabilization with a 12 megapixel sensor. The sensor itself is 60% faster and 30% more energy efficient with a wider f1.8 aperture lens and new six-element lens. The Flash is now a quad LED true tone system. There’s also software enhancements that uses machine learning to read the scene to set focus, exposure, and color. There are over 100 billion operations in 25 milliseconds. The front camera has also been improved with a bump from 5 megapixels to 7 megapixels with auto image stabilization, and the same wide color capture.
The iPhone 7 Plus camera is even better with a dual lens system. The two lenses are wide angle and telephoto. This allows for true optical zoom, rather than just digital zoom of blowing up the pixels. There’s a new software button in the camera app on the 7 Plus allowing you to tap to zoom to 2x. You can zoom to 5x and 10x, but those are digital zoom. There’s also a new depth of field photo system to create the Bokeh art style. The dual camera system creates a depth map to find the subject, and blur the background with a live preview.
