Multi-lenses smartphones


Smartphones are now many to integrate two or three lenses, or more. Some even have real optical zooms.

IPhones 11 are required, they have an optical block with three lenses:

  • The wide angle remains the main block, with the best quality, with a "large sensor" of 1/2.55" whose photos are not measured, 1.4 microns, fully carpeted with focus pixels stabilized with six elements, with a focal length of 4.25 mm (equivalent to 26 mm), which opens at ƒ/1.8.
  • The telephoto lens retains its 1/3.4" sensor with small 1 μm photosites, but its optics is stabilized with six elements, with a focal length of 6 mm (equivalent to 52 mm), fully open to ƒ/2 , 0.
  • The very wide angle, finally, the block less well provided of the three. Its optics have "only" five elements, opens at f/2.4, and is not stabilized. While its 1.54mm focal length is reported as a 14mm equivalent, its sensor probably does not seem likely to be 1/4".
