Sony patents camera lens design that moves two groups to focus
Sony has filed a patent for an optical system used in cameras. It features four groups of lenses, with the second and fourth groups sliding along the center line to adjust focus when taking pictures.
In the filing’s own words
An optical system according to the present disclosure includes, in order from a side of an object toward a side of an image plane: a first lens group having positive refractive power; a second lens group having positive refractive power; a third lens group; and a fourth lens group having positive refractive power. The second lens group and the fourth lens group move on an optical axis upon focusing.
What exactly they claim (claim 1)
1. An optical system comprising, in order from a side of an object toward a side of an image plane: a first lens group having positive refractive power; a second lens group having positive refractive power; a third lens group; and a fourth lens group having positive refractive power, wherein the second lens group and the fourth lens group move on an optical axis upon focusing.
