Question: what is difference between the iphone 6 and 7?
Answer: The iPhone 7 and iPhone 6s have 12-megapixel sensors on the back, but where the real difference comes is with aperture, pixel size, and post-processing. The 7 has f/1.8 aperture compared with the 6s's f/2.2, giving it a bigger pixel size, optical image stabilization, and longer exposure.
