For the camera, the iPhone 11 Pro uses a triple-lens setup, which includes the same focal lengths as found on the iPhone XS – a 26mm “standard” lens with an f/1.8 maximum aperture, plus a 52mm “telephoto” lens, which now has a wider f/2.0 aperture.
A brand new addition for the 11 Pro is the 13mm “ultra wide” lens, with an aperture of f/2.4. All three cameras are backed by 12 megapixel sensors.
