Canon Filed A Patent For Fish Eye 8-15mm F4, 16mm F2.5, and 17mm F2.5 Lenses

By Louis Ferreira | Published: January 28, 2025


Canon filed a patent for Fish Eye 8-15mm F4, 16mm F2.5, and 17mm F2.5 lenses.

overview

  • [Publication number] JP2025-12993 (P2025-12993A)
  • [Release date] January 24, 2025 (2025.1.24)
  • [Name of invention] Lens device and imaging device
  • [Application date] July 14, 2023 (2023.7.14)
  • [Applicant]
    [Identification number] 000001007
    [Name or company name] Canon Inc.
  • By adding another optical system to a master optical system, distortion is suppressed while avoiding an increase in the size of the entire optical system.
  • 2. Description of the Related Art
    [0002]
    As a method for obtaining a wide-angle lens with low distortion from a fisheye lens, Patent Document 1 discloses a method for converting the projection method of a fisheye lens to a general projection method by placing an aspherical dome-shaped lens with negative refractive power on the object side of the fisheye lens (master optical system). Patent Document 2 discloses a method for changing the projection method by exchanging an intermediate portion between the object side and image side of the optical system.
  • Placing a dome lens on the object side of a fisheye lens as in Patent Document 1 leads to an increase in size of the entire optical system. Furthermore
    , the method of replacing an intermediate part of the optical system as in Patent Document 2 requires replacement work and the configuration to enable replacement becomes complicated.
  • The present invention
    provides a lens device that can suppress distortion while avoiding an increase in the size of the entire optical system by adding another optical system to the master optical system.

Canon Filed A Patent For Internal Zoom Wide-Angle 16-30mm F2.8, 15-35mm F2.8, and 14-28mm F2.8 Lenses With Electronic Control

By Louis Ferreira | Published: January 27, 2025


Canon filed a patent for internal zoom wide-angle 16-30mm F2.8, 15-35mm F2.8, and 14-28mm F2.8 lenses with electronic controls.

overview

  • [Publication number] JP2025-11796 (P2025-11796A)
  • [Release date] January 24, 2025 (2025.1.24)
  • [Name of invention] Zoom lens and imaging device
  • [Application date] July 12, 2023 (2023.7.12)
  • [Applicant]
    [Identification number] 000001007
    [Name or company name] Canon Inc.
  • A zoom lens having high optical performance is provided.
  • 2. Description of the Related Art
    [0002]
    Patent Document 1 discloses a zoom lens that moves the first lens group toward the object side and the second lens group toward the object side when focusing, thereby reducing the change in the angle of view. Patent Document 2 discloses a zoom lens that has two focusing groups, a focusing group and a final lens group within the first lens group, and switches the group that moves when focusing according to the zoom position.
  • [0004] In the zoom lens disclosed in Patent Document 1, the correction is made by zooming using a zoom cam, so correction is difficult in a configuration that does not allow motorized zooming, such as an interchangeable lens. In the zoom lens disclosed
    in Patent Document 2, the lens in the first lens group, which has a large lens diameter and is heavy, is moved, so it is difficult to motorize it, and it is also difficult to reduce the change in the angle of view over the entire zoom range. For this reason, it is difficult to realize a zoom lens with high optical performance with the configurations disclosed in Patent Documents 1 and 2.
  • During zooming, the first lens group B1 and the seventh lens group B7 are fixed, and the second lens group B2 to the sixth lens group B6 move toward the object side. The zoom lens 1a of this embodiment has the following features: since the overall length does not change during zooming, there is little change in the center of gravity, which is advantageous for dust resistance; furthermore, the zoom torque is low, which makes it easy to accommodate a later-installed electric zoom attachment; and it is therefore suitable for use in video photography.
  • The image height indicates both the paraxial image height and the real image height, and it is assumed here that image distortion caused by distortion aberration is corrected by processing the captured image.


Example 1

  • Focal length: 16.40-30.00
  • F-number: 2.88
  • Half angle of view: 52.84-35.80
  • Image height: 21.64
  • Real image height: 18.61-21.42
  • Total length: 158.40
  • Back Focus: 17.19


Example 2

  • Focal length: 15.40-34.50
  • F-number: 2.88
  • Half angle of view: 54.55-32.09
  • Image height: 21.64
  • Real image height: 18.61-22.06
  • Total length: 179.35
  • Back focus: 20.01-25.54


Example 3

  • Focal length: 14.42-27.40
  • F-number: 2.88
  • Half angle of view: 56.31-38.30
  • Image height: 21.64
  • Real image height: 18.61-22.06
  • Total length: 154.50
  • Back focus: 13.95-18.90
