Patents for a Canon 200-400mm f/4 and 200-500mm f/5.6 have been found, which include the Canon RF 70-200mm f/2.8 L IS USM Z. You can check out the filing below:

overview

  • [Publication number] P2025080464
  • [Release date] 2025-05-26
  • [Name of invention] Zoom lens and imaging device
  • [Application date] 2023-11-14
  • [Applicant]
    [Identification number] 000001007
    [Name or company name] Canon Inc.
  • To suppress aberration fluctuation and one-sided aperture occurrence that occur during zooming in a small and lightweight zoom lens.
  • [Background Art]
    [0002]
    In a zoom lens, the moving lens group is required to be lightweight in order to suppress the change in the center of gravity that accompanies the movement of the lens group during zooming, to reduce the torque required to drive the lens group, etc. Also, during focusing, it is required that the change in the angle of view is small, i.e., focus breathing is small, and the moving lens group (focus group) is lightweight.
  • [0003]
    In a large-aperture telephoto zoom lens, the refractive power of the first lens group, which is the closest to the object, is generally positive. In this case, by fixing the first lens group, which is the heaviest, and adopting rear focusing, it is possible to reduce the weight of the lens groups that move during zooming and focusing. In addition, since the change in the angle of view due to focus breathing is more noticeable when the aperture is narrowed, it is required that focus breathing be small when the aperture is narrowed.
  • [0004]
    However, if the diameter of the first lens group is kept small while ensuring sufficient peripheral light volume in order to achieve a compact and lightweight zoom lens, the chief ray of the peripheral light flux is likely to shift from the center of the aperture, resulting in a so-called one-sided aperture state. If the aperture is narrowed in a one-sided aperture state, focus breathing due to the movement of the lens group on the image side of the aperture tends to increase. In addition, even if the aperture is opened, the amount of light is unlikely to increase, and the blurred image becomes asymmetrical.
  • The present
    invention provides a zoom lens which is small and lightweight, yet has high optical performance over the entire zoom range and the entire focus range by suppressing the occurrence of aberration fluctuations and one-sided aperture caused by zooming.


Example 1

  • Focal length: 72.00-194.00
  • F-number: 2.90
  • Half angle of view: 16.72-6.36
  • Image height: 21.64
  • Total length: 217.10
  • Back Focus: 37.13


Example 2

  • Focal length: 60.00-180.00
  • F-number: 2.90
  • Half angle of view: 19.83-6.85
  • Image height: 21.64
  • Total length: 210.00
  • Back Focus: 37.12


Example 3

  • Focal length: 100.00-291.00
  • F-number: 2.90
  • Half angle of view: 12.21-4.25
  • Image height: 21.64
  • Total length: 320.20
  • Back focal length: 37.14


Example 4

  • Focal length: 205.00-395.00
  • F-number: 4.10
  • Half angle of view: 6.02-3.14
  • Image height: 21.64
  • Total length: 350.00
  • Back focal length: 43.54


Example 5

  • Focal length: 205.00-495.00
  • F-number: 5.75
  • Half angle of view: 6.02-2.50
  • Image height: 21.64

Godox iT30Pro C TTL Mini Flash

By Louis Ferreira | Published: May 23, 2025


Godox iT30Pro C TTL: B&H Photo / Amazon

Developed as a highly portable TTL flash for use with Canon cameras, the iT30Pro C TTL Mini Flash from Godox is an effective lighting tool with automated flash settings. Offering support for Canon E-TTL / E-TTL II and the built-in Godox 2.4 GHz X wireless radio system, the iT30Pro C can be used as a transmitter or receiver unit. Use it to trigger select Godox flashes with 2.4 GHz X system compatibility. As a receiver, the iT30Pro C can be controlled by an optional Godox transmitter. The flash supports TTL, manual and multi flash modes, HSS, second curtain sync, FEC, WN switch, and other handy functionalities. A compact and versatile lighting control device, the flash features a convenient 2.8″ full-color touchscreen interface for comfortable operation and a shoe-mounted housing for compatibility with a wide variety of cameras. The iT30Pro C is ideal for photographers in need of a compact and reliable camera-mountable light source with TTL capability. The iT30Pro C’s modern and sleek design in black finish will also elevate the aesthetics of your camera.

The First Godox Mini TTL Flash
The iT30Pro C offers automatic and manual controls and works well for photographers of all experience levels, including beginners or those working with smaller-scale shoots. It arrives as the brand’s first TTL flash in a mini format—measuring only 2.6 x 1.9 x 1.8″. The iT30Pro C has a guide number of 49.2′ at ISO 100 and flash durations from 1/1000 to 1/30,000 sec. You can also manually adjust the flash’s output from 1/128 to full power to achieve greater lighting precision.

WN Switch
Effortlessly toggle between W and N modes using an integrated WN switch placed on the side of the flash body. The W mode enables the wide-angle diffuser to extend the flash range, while providing even lighting at a close distance. When selecting the N mode, the flash maintains high light intensity over a longer distance, while the diffuser is off.

Built-In Rechargeable Battery
After charging with the flash’s included USB-C cable, the iT30Pro C’s built-in 7.2V, 900mAh lithium battery provides up to 560 full power flashes with a 1.5 sec recycling time.

2.4 GHz X Wireless Radio System
The Godox 2.4 GHz X radio system is incorporated into the iT30Pro C for transmitter and receiver functionality. The iT30Pro C functions as a transmitter unit for select Godox flash units, while also working as a receiver unit for the separately available XPro, X2, and X3 transmitters. This compatibility with Godox’s X series flashes or transmitters enables more functionality and diverse setups. The iT30Pro C wireless system has a range of 328′, featuring four groups and 32 channels.

Control at Your Fingertips
The iT30Pro C has an intuitive touchscreen interface and onboard controls for easy and quick access to the flash settings. Indicators are available on the LCD panel to inform the remaining battery level.

Firmware Updates
Firmware updates via USB-C port ensure compatibility with the latest camera models and optimal performance.

Canon’s EOS R1 Full-Frame Mirrorless Camera Wins Highest Honor at International Red Dot Design Awards
Canon Inc., the parent company of Canon U.S.A., Inc., a leader in digital imaging solutions, announced that the company’s EOS R1 full-frame mirrorless camera, intended for professionals, won the “Best of the Best,” the highest honor, at the Red Dot Design Award: Product Design 2025 competition hosted by the Switzerland-based Red Dot Award AG. The awards ceremony will be held on July 8 in Essen, Germany.

The EOS R1 camera, released in November 2024, is the first flagship model in the EOS R System series. Thanks to a powerful image processing system introduced in this camera for the first time, and the use of deep learning technology, the EOS R1 camera is designed to achieve a high level of photographic performance required by professional photographers. Through functions such as Action Priority1, which recognizes certain actions including soccer shots by instantly shifting the AF frame, and eye-control AF2, the device is capable of persistently tracking target subjects.

Its rubber grip features a specially designed cross pattern with a strong grip capability that helps improve the camera’s handling performance by protecting the device from being dropped when changing between vertical and horizontal positions. Additionally, locking mechanisms are installed on moving segments of the camera, including the diopter-adjustment dial and card slot cover, to thoroughly prevent unintended operation. Through comfortable operability and a shape rooted in ergonomics, the camera achieves a design fit for professional users.

The EOS R1 camera has received high praise for its design, earning the iF Design Award 2025 (Germany), which is similarly as internationally prestigious as the Red Dot Design Award. This award is a reflection of Canon’s ongoing commitment to create products that expertly blend performance with design.

About the Red Dot Design Award
The Red Dot Design Award, established in 1955, is one of the world’s largest design-centered awards competitions. Excellent designs are chosen in three divisions—Product Design, Brand & Communication Design, and Design Concept. This year, entries from over 60 countries and regions were evaluated by internationally renowned design specialists under nine criteria including innovation, functionality, quality, and ergonomics.
