Canon Patent: RF 18-35mm f/1.8 DS & RF 120-300mm f/2.8 DS (Defocus Smoothing)

Defocus Smoothing

And here is another Canon patent application for two RF-mount lenses with Defocus Smoothing technology.

Canon patent application 2022175307 (Japan, published 11/25/2022) discusses optical formulas for two RF-mount lenses with Defocus Smoothing technology, RF 18-35mm f/1.8 DS & RF 120-300mm f/2.8 DS. No surprise Canon is porting this technology to the RF-mount. From the patent literature:

To provide a variable power optical system that obtains a good apodization effect over the entire zoom range and that has a small change in T number with variable power.

Description of the Related Art

Conventionally, in order to obtain an appropriate blurred image, there has been known an optical system equipped with a filter whose transmittance distribution changes, such as an apodization filter whose transmittance decreases as the distance from the optical axis increases. ing. Patent Literature 1 discloses an optical system in which apodization filters are arranged before and after the aperture of a single-focus lens.

However, since the optical system disclosed in Patent Document 1 is a single focus optical system, it is insufficient as a method for obtaining a sufficient apodization effect in each zoom state of the variable magnification optical system. In addition, as a specific requirement of a variable-magnification optical system, it is required that the change in brightness, that is, the T-number, is small when the magnification is varied, especially in video shooting.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide a variable magnification optical system and an optical apparatus which have a good apodization effect over the entire zoom range and have a small change in T-number due to variable magnification.

Example 1

  • Focal length: 18.60-33.78
  • F-value: 1.80-1.86
  • Half angle of view: 37.69-23.05

Canon Patent: RF 24-120mm f/2.8 IS & RF 85mm f/1.4 IS

Canon Patent

A new Canon patent application for a RF 24-120mm f/2.8 IS and RF 85mm f/1.4 IS lenses.

Canon patent application 2022175604 (Japan, published 11/25/2022) discusses optical formulas for two RF mount lenses, RF 24-120mm f/2.8 IS and RF 85mm f/1.4 IS. From the patent literature:

An object of the present invention is to reduce the size and weight of a movable group decentered with respect to an optical axis, while suppressing the occurrence of chromatic aberration due to the movable group.

Example 1

  • Focal Length: 24.72-116.36
  • F-value: 2.91
  • Half angle of view: 37.12-10.53
  • Image height: 21.64
  • Total length: 178.45-204.02
  • Back focus: 14.59

Example 2

  • Focal length: 82.47
  • F-value: 1.45
  • Half angle of view: 14.70
  • Image height: 21.64
  • Overall length: 126.52
  • Back focus: 13.50

Example 3

  • Focal length: 103.16-387.89
  • F-value: 4.64-7.30
  • Half angle of view: 11.84-3.19
  • Image height: 21.64
  • Total length: 176.10-288.59
  • Back focus: 15.98-63.01

  • Same Dual Pixel CMOS AF II from EOS R3 and EOS R6 Mark II
  • Internal 8K 60p video recording (8K RAW video spec to be confirmed)
  • Internal 4K 30p/60p/120p video recording (all by oversampling)
  • FHD 240p video recording
  • Focus breathing correction for video
  • New overheat prevention design similar to EOS R6 Mark II, at least 40min for 8K video, and over
