Canon Patent: 135mm f/2 1:2 Macro And 200mm f/2.4 1:2 Macro Lenses

Canon patent
View Post

And yet another Canon patent application: 135mm f/2 1:2 Macro And 200mm f/2.4 1:2 Macro Lenses.

Canon patent application 2022-22595 (Japan) discusses optical formulas for two macro lenses: 135mm f/2 1:2 M.

PROBLEM TO BE SOLVED: To provide an optical system capable of expanding a close range in a small size while suppressing the number of focus groups, and an image pickup apparatus having the same.

If the floating focusing method is used to increase the close-up magnification, the number of lenses in each group increases, and it is difficult to drive the focus group at high speed. In the lenses of Patent Document 1 and Patent Document 2, when the number of lenses in the focus group is reduced in order to realize high-speed drive, sufficient aberration performance cannot be obtained because the configuration of each group is not appropriate.

An object of the present invention is to provide an optical system capable of expanding a close range in a small size while suppressing the number of focus groups, and an image pickup apparatus having the same.

Example 1

  • Focal length: 133.0
  • F value: 2.05
  • Half angle of view: 9.24
  • Image height: 21.64
  • Shooting magnification: -0.5

Example 3

  • Focal length: 200.0
  • F value: 2.40
  • Half angle of view: 6.18
  • Image height: 21.64
  • Shooting magnification: -0.5

Example 4

  • Focal length: 199.9
  • F value: 2.80
  • Half angle of view: 6.18
  • Image height: 21.64
  • Shooting magnification: -1.00

Canon Patent: Rotating Built-in Extender (so you may operate it with just your right hand)

canon patent
View Post

A new Canon patent. What about a rotating built-in extender you can operate with just one hand?

Canon patent application 2022-23481 (Japan) discusses methods and technology for a built-in rotating extender.

PROBLEM TO BE SOLVED: To provide an optical device advantageous in terms of operability.

Patent Document 1 discloses a lens device including a lens group that can be inserted and removed with respect to an optical axis by an operating member (lever). Further, Patent Document 2 discloses a lens device having a support structure that supports a filter that can be inserted and removed from the optical axis by an operating member.

If the position and operation direction of the operation member are uniquely determined in Patent Document 1 and Patent Document 2, for example, depending on the operator and the operation situation, it may be disadvantageous in terms of operability. An object of the present invention is, for example, to provide an optical device which is advantageous in terms of operability. An optical device 100 is rotatably fixed to a lens barrel portion 11 around a lens 11L, a lens barrel portion 11 holding at least a part of the lens 11L, and an optical axis O of the lens 11L. It has a rotating housing 12, and the rotating housing 12 includes an extender lens barrel 17 that supports a converter 17L that is inserted and removed with respect to the optical axis O.

The Canon patent application was spotted by asobinet.com. They say:

Yesterday [we found a] a patent application that seemed to envision the 400mm F4 DO IS Extender 1.4 × and 600mm F4 IS Extender 1.4 ×, and now a patent application for the structure of the built-in extender has been published. This time, The fact that the structure of the optical system and the moving parts have appeared in a series of patents suggests that they are seriously considering a telephoto single focal length lens with a patent application for the structure of the built-in extender has been published. built-in extender.
This patent application is not just about the movable parts of the built-in extender, but it also aims to make the movable parts rotating to provide operability suitable for various shooting styles.

For example, the current lens with built-in extender, the EF200-400mm F4L IS USM Extender 1.4 ×, has the extender switching lever positioned for left hand operation, so it is not compatible with right hand operation. In fact, some people have commented that they wished it was placed in a position where it could be used for right-handed operation like Nikon’s, so there may be demand for improved operability.
I am wondering if this structure can be implemented in the telephoto L-series, which requires Robustness, but it seems highly likely that research and development is underway for lenses with built-in extenders. We may see more patent applications like this in the future.

Canon Patent: Switch Between Electronic And Dot-sight Viewfinder

View Post

This seems a rather interesting and innovative Canon patent application. How about switching between dot-sight and electronic viewfinder?

Canon patent application 2022-23783 (Japan) discusses methods and technology for a device that allows to switch between dot-sight and electronic viewfinder. If you want to learn more about dot-sight, have a look here.

PROBLEM TO BE SOLVED: To provide a small display device capable of switching between a sight and an electronic viewfinder.

Conventionally, when a distant moving subject such as a bird or an airplane is photographed by using an image pickup device, a sighting device called a dot sight is widely used. Further, in an image pickup device equipped with a high-magnification lens, a display device such as an electronic viewfinder is widely used in order to enable stable shooting. Patent Document 1 discloses an image pickup apparatus including both an electronic viewfinder and a sighting device.

However, in the image pickup device disclosed in Patent Document 1, since the function of the sighting device and the function of the electronic viewfinder are realized by using different display devices, the size of the image pickup device becomes large.

The display device as one aspect of the present invention is arranged between the image display element, the eyepiece, the objective window, and the eyepiece and the objective window, and is displayed on the image display element. It has a reflective optical element that guides the image to the eyepiece, and the reflective optical element can switch between the first state and the second state by changing the transmission rate, and the first state. In, the image displayed on the image display element can be visually recognized through the eyepiece, and in the second state, the image from the objective window and the image through the eyepiece. It is possible to visually recognize an image in which an image displayed on the display element is superimposed.

According to the present invention, it is possible to provide a small display device and an image pickup device capable of switching between a sighting device and an electronic viewfinder.

Is this cool? Me thinks it is.
