Canon patent application 2024010559 (Japan, published 01/24/2024) discusses optical formulas for two macro lenses for the RF mount:

  • 50mm f/4 IS Macro
  • 90mm f/4 IS Macro

From the patent literature:

  • An object of the present invention is to provide a compact and high-performance optical system in a macro lens, in which a focus lens group is made lighter and smaller, achieving higher focus stop precision and faster focusing speed.
  • BACKGROUND ART
    A macro lens is known as a lens capable of close-up photography. In recent years, there has been a demand for a macro lens that has high optical performance with little aberration variation in the entire focus region.
  • Patent Documents 1 and 2 disclose macro lenses that correct aberration fluctuations during focusing by moving a large focus lens group during focusing.
  • However, in the macro lenses described in Patent Documents 1 and 2, the actuator becomes large in order to move a large focus lens group, and the focus lens group becomes large, resulting in a decrease in focus stop accuracy and focus speed. There was a problem.
  • The present invention provides a compact and high-performance optical system in a macro lens by reducing the weight and size of the focus lens group, achieving high focus stop precision and high speed focusing speed.

Canon Patent: 10-18mm f/4.5-6.3 and 10-20mm f/4 (with internal zoom)

Canon Patent
View Post

Canon patent application 2024007656 (Japan, published 19/01/2024) discusses optical formulas for two wide angle zoom lenses.

  • 10-18mm f4.5-6.3
  • 10-20mm f/4 with internal zoom mechanism

From the patent literature:

  • An object of the present invention is to provide a zoom lens that has high optical performance, is compact, and has a wide angle of view.
  • BACKGROUND ART
    Wide-angle lenses are widely used for landscape photography, astronomical photography, and the like. Wide-angle lenses are required to have high optical performance and realize a wide angle of view while being compact.
  • Generally, in a negative read optical system, the constituent lens groups are arranged asymmetrically, making it difficult to correct various aberrations such as astigmatism. In particular, when widening the angle of view or downsizing the lens, the refractive power of the lens group closest to the object, which has a negative refractive power, becomes stronger, so that many of the above-mentioned aberrations occur.
  • For this reason, in order to achieve a wide angle of view and miniaturization in a negative lead type optical system, and to properly correct various aberrations such as curvature of field and obtain high optical performance, the refractive power of each lens group must be adjusted. It is important to set these appropriately.
  • In Patent Document 1, various aberrations such as astigmatism and field curvature are corrected by weakening the refractive power of each lens group, but this increases the size of the optical system, which is undesirable.
  • Accordingly, an object of the present invention is to provide a zoom lens that has high optical performance, is small in size, and has a wide angle of view.

Example 1

  • Focal length: 10.30-17.50
  • F value: 4.63-6.13
  • Half angle of view: 53.0-38.0
  • Image height: 11.28-12.95
  • Total length: 74.63-73.78
  • Back focus: 10.97

Example 2

  • Focal length: 15.00-29.10
  • F value: 4.63-6.42
  • Half angle of view: 55.-36.3
  • Image height: 17.85-21.46
  • Total length: 122.37-109.82
  • Back focus: 13.33

Example 3

  • Focal length: 10.30-21.35
  • F value: 4.63-6.33
  • Half angle of view: 53.0-32.5
  • Image height: 11.38-13.66
  • Total length: 84.74-75.36
  • Back focus: 10.97-14.95

Example 4

  • Focal length: 10.30-19.40
  • F value: 4.12
  • Half angle of view: 52.9-35.2

Canon Patent: 400mm F2.8, 500mm F4 And 600mm F4 Lenses

Canon patent
View Post

New Canon patent for you, ladies and gentlemen. Canon patent application 2024009238 (Japan, published 01/19/2024) discusses optical formulas for three telephoto prime lenses, all for fullframe mirrorless cameras.

  • 400mm F2.8
  • 500mm F4
  • 600mm F4

From the patent literature:

  • [Problem] To obtain an optical system that is lightweight and in which aberrations such as chromatic aberration are well corrected.
  • [ Background Art] As a photographing optical system with a long focal length, a so-called telephoto type photographing system has an optical system with positive refractive power on the object side and an optical system with negative refractive power on the image side. optical system is known. A telephoto type photographing optical system is used, for example, in a single focus super telephoto lens.
  • In a super telephoto lens, generally, as the focal length becomes longer, axial chromatic aberration and lateral chromatic aberration occur more frequently. As a method for properly correcting these chromatic aberrations, it is known to increase the number of lenses arranged on the object side and have each lens share the function of correcting the chromatic aberrations. However, a lens placed on the object side of a super-telephoto lens tends to have a large effective diameter, and if the above-mentioned method is used to correct chromatic aberration, the weight of the photographic optical system increases.
  • In the photographing optical system of Patent Document 1, by arranging a positive lens made of a material having low dispersion and anomalous dispersion continuously from the object side, longitudinal chromatic aberration and lateral chromatic aberration can be corrected. I’m trying.
  • In order to further reduce the weight of the optical system, it is important to find an appropriate material and arrangement not only for the positive lens but also for the negative lens.
  • An object of the present invention is to provide an optical system that is compact and in which aberrations such as chromatic aberration are well corrected, and an imaging device having the same.

Example 1

  • Total length: 360.03
  • Back focus: 31.01

Example 2

  • Focal length: 490.00
  • F value: 4.12
  • Half angle of view: 2.53
  • Image height: 21.64
  • Total length: 412.08
  • Back focus: 33.39

  • Focal length: 588.00
  • F value: 4.12
  • Half angle of view: 2.11
