The 8-megapixel camera found in the iPhone 6 and 6 Plus are basically identical, except for the fact that the one in the 6 Plus is equipped with optical image stabilization. As we've explained before, that feature is designed to compensate for hand-shake and camera movement, making it a potentially better solution for taking shots of non-moving objects and stabilizing video.
