Canon Patent: RF-S 33mm f/1.8 And Other Lenses

Canon Patent

Here is a new Canon patent application for a bunch of lenses, of which one might already have releases.

Canon patent application 2024082112 (Japan, published 6/19/2024) discusses optical formulas for three lenses:

From the patent literature:

  • [Background Art] With the miniaturization and high pixel count of image sensors, optical systems used in imaging devices are required to be small and have high optical performance. In order to satisfy these requirements, Patent Document 1 proposes an optical system consisting of a first lens with positive refractive power, a second lens with negative refractive power, a third lens, a fourth lens, a fifth lens, and a sixth lens arranged in order from the object side to the image side. The lens surface on the object side of the first lens is convex near the optical axis. The lens surface on the image side of the second lens is concave near the optical axis. The lens surface on the object side of the third lens is convex near the optical axis. The lens surface on the image side of the fourth lens is convex near the optical axis. The lens surface on the object side of the fifth lens is convex near the optical axis. The lens surface on the image side of the sixth lens is concave near the optical axis.
  • In order to reduce the overall length of an optical system, it is effective to adopt a telephoto type power arrangement and strengthen the positive refractive power on the object side and the negative refractive power on the image side. However, when the power arrangement of a telephoto type is strengthened, a large pincushion distortion occurs, making it difficult to simultaneously correct distortion and curvature of field with a limited number of lenses. In addition, when the power arrangement of a telephoto type is strengthened, the back focus becomes shorter and the exit angle of the off-axis light beam becomes larger.
  • The optical system described in Patent Document 1 employs a telephoto power arrangement to reduce the overall length, and uses multiple aspheric lenses to correct distortion and curvature of field, but the Petzval sum of the entire system is large and the exit angle of the off-axis light beam is also large. Therefore, when attempting to apply the optical system described in Patent Document 1 to an imaging device with a large image sensor, the correction of curvature of field and the reduction in peripheral light amount become issues.
  • The present invention provides an optical system that is small, lightweight, and has high optical performance.
  • In the optical system L0 of each embodiment, the final lens Lp is preferably made of plastic. The diameter of the final lens Lp is generally large, and using glass as the material for the final lens Lp is not preferable because the lens weight becomes heavy.

Canon Patent: 15-60mm f/2.8 And 22-80mm f/2.8 With Inner Zoom Mechanism

Canon Patent

A new Canon patent for two lenses with inner zoom mechanism. Canon patent application 2024079936 (Japan, published 6/13/2024) discusses optical formulas for two (likely RF-mount) lenses with an inner zoom, i.e. they do not extend or retract when zooming:

  • 5-60mm f/2.8
  • 22-80mm f/2.8

From the patent literature:

  • A zoom lens that has a high zoom ratio and a large aperture ratio, yet is compact, lightweight, and provides high image quality, and that allows high-speed zoom operation.
  • Background Art
    There is a demand for a zoom lens that is compact and lightweight throughout its entire system, has excellent correction of chromatic aberration and other aberrations, and has high optical performance. There is also a demand for a zoom lens that has a short focal length at the wide-angle end, a large zoom ratio, a small F-number, a large aperture ratio, and is easy to manufacture. There is also a demand for a zoom lens that allows high-speed zoom operation.
  • However, the zoom lens described in Patent Document 1 has a tendency to have a large lens diameter due to its small F-number, and the large front lens diameter leads to an increase in size and weight. In addition, if the refractive power of the second lens group is increased in order to reduce the front lens diameter, it becomes difficult to achieve high image quality.
  • The present invention provides a zoom lens that has a high zoom ratio and a large aperture ratio, yet is compact, lightweight, and provides high image quality, and is capable of high-speed zoom operation.

Example 1

  • Focal length: 24.72-101.86
  • F-number: 2.90
  • Half angle of view: 41.19-11.99
  • Total length: 212.40
  • Back Focus: 11.98-21.74

Example 2

  • Focal length: 15.45-58.20
  • F-number: 2.90
  • Half angle of view: 41.5-13.2
  • Image height:
  • Overall length: 144.55
  • Back focal length: 13.62

Example 3

  • Focal length: 24.71-116.38
  • F-number: 2.90
  • Half angle of view: 41.3-10.0
  • Image height:
  • Overall length: 231.23
  • Back focus: 11.38-23.01

Example 4

  • Focal length: 22.60-82.99
  • F-number: 2.90
  • Half angle of view: 44.3-14.1
  • Image height:
  • Overall length: 216.25
  • Back Focus: 11.83-22.33

Here is a new Canon patent application. Does the patent refer to the Canon RF 24-70mm f/2.8L IS?

Canon patent application 2024078721 (Japan, published 6/11/2024) discusses optical formulas for a 28-70mm f/2.8 IS lens.

From the patent literature:

  • The present invention provides a compact zoom lens that has a high zoom ratio, good optical performance over the entire zoom range from the wide-angle end to the telephoto end, and has a large aperture and an image stabilization mechanism.
  • Background Technology
    In recent years, zoom lenses used in imaging devices such as digital cameras using solid-state imaging elements and silver halide film cameras are required to be small in size, have high optical performance, have a large aperture, and be equipped with an image stabilization mechanism (anti-vibration mechanism).
  • In order to achieve this, it is important to appropriately set the zoom type of the zoom lens and the lens group that moves during zooming.
  • The present invention provides a compact zoom lens that has a high zoom ratio and good optical performance over the entire zoom range from the wide-angle end to the telephoto end, has a large aperture, and has an image stabilization mechanism.
