Cameras
The camera system on the iPhone 6s includes a 12 MP rear camera with an f/2.2 aperture and 1/3.0" sensor size, capable of producing good quality images. Features such as PDAF, dual-LED dual-tone flash, and HDR contribute to a varied photography experience. The ability to shoot 4K video at 30 fps was pioneering at its release, and it offers additional modes including 1080p at both 60 fps and 120 fps, and 720p at 240 fps for slow-motion capture. The 5 MP front camera, equipped with HDR and panorama functions, is competent for selfies and video calls, capturing video at 720p at 30 fps.
