Samsung Galaxy S7 vs iPhone 7: Camera
Samsung's camera tech is pretty impressive and capable, while also being extremely easy to use and get good results for even the most inexperienced and non-camera-savvy users. It features a 12MP sensor with an f/1.7 aperture size, an optical image stabilisation (OIS) module, dual-LED two-tone flash, and Samsung's amazing dual-pixel phase detection autofocus.
It remains to be seen how well Apple's camera tech performs, but this is where the most advanced changes on the iPhone 7 series have taken place. The standard iPhone 7 model features a 12MP sensor with an f/1.8 aperture, OIS, an updated 6-element lens, a quad-LED TrueTone LED flash with flicker sensor (for capture in artificial lighting), and a new image signal processor. For the larger iPhone 7 Plus model things get even more involved as it has two 12MP sensors in a dual-sensor setup; one sensor has a telephoto lens and the other a wide-angle lens; combining all the image data for a much more detailed image as standard, but also allowing for a x2 optical zoom and 10x software zoom, and Bokeh depth-of-field effects.
