You can see from the details below that the iPhone 11 Pro cameras have a fixed aperture and ISO and shutter speed have a narrow range. Compare to my Fuji X-T2 + Fujinon XF16-55mmF2.8 R LM WR lens. The iPhone 11 Pro cameras have a fixed aperture of ƒ/1.8, ƒ/2.0, ƒ/2.2 and ƒ/2.4. The lenses can not be stopped down. The iPhone 11 Pro always shoots wide open. The iPhone 11 Pro cannot shoot at ISO higher than 3072. The slowest shutter speed is 1s which limits its use for long-exposure photography. Without software trickery, the iPhone 11 Pro is limited in its ability to create long exposure images or aperture priority images or photographs in low light.
