We have some very unique lens patterns from Canon. The first lens is 15 to 60 mm f/2.8. This is being developed for Canon RF mount, most importantly the lens has inner zoom mechanism and from the overall details, it look like a part of the Canon L series lens with highest grade optics possible. The 15-60mm F2.8 lens is a very unique focal length, it will be nowadays more accepted than the 24-70mm focal length without a doubt., take a look at the details below
overview
- [Publication number] P2024079936
- [Release date] 2024-06-13
- [Name of invention] Zoom lens, and imaging device and imaging system having the same
- [Application date] 2022-12-01
- [Applicant]
[Identification number] 000001007
[Name or company name] Canon Inc.
- 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.
In addition to the 24-105mm, examples of the inner zoom structure “15-60mm F2.8” and “22-80mm F2.8” are also included. The 15-60mm F2.8 looks very convenient. Details are unclear as to whether these will become the “F2.8 Z” series under consideration in the future, or whether they were born during the development process of the 24-105mm F2.8 in Aqua. (Although there are rumors that other Z series will appear) it is too early to expect their

Canon’s latest patent allows users to explore more AUTOFOCUS modes while shooting a video. The patent describes that even if a user is recording video, during the recording the new AF modes allow users to enhance the user experience to the next level.
The Lenses Control Button will allow to explore more AF modes on the camera screen allowing users to select the type of AF modes they want during the shoot
So users will get these three new functions in upcoming Canon cameras
As you can see the user will have three different options on the camera screen the
1. first the manual focus is not executable during the autofocus
2. The second option is the manual focus, which is executable for the lens’s focus ring, even when the camera is in fully autofocus mode.
3. The third option is the manual focus is executable after the autofocus is complete
A lens apparatus connected to a camera, includes: a focus lens; a driving unit which drives the focus lens; an operation input unit; a mode switcher that switches between first and second modes relating to selection between AF and MF and a selection of an operation target of the operation input unit, and a controller, in which the controller, in the first mode, controls the driving unit based on an input from the operation input unit and controls a driving of the focus lens unit in MF, and in which the controller, in the second mode, outputs a control signal to change image pickup parameter based on input from the operation input unit, controls the driving unit in AF based on an AF control signal input from the camera when a set value input from the camera is AF-executable, and does not perform AF when the set value is AF-not-executable.

Canon next next-generation vlogging camera patent surfaced today, the design being shown in the patent is slightly different from the existing Canon V10 camera. Also, the sensor area shown in the figure resembles an APS-C sensor instead of a 1-inch sensor being used in the Canon V10 camera, take a look at the images below
Now you have noticed the difference at the front and top part of the vlogging camera and now it’s time to look at the rear part of the camera and notice the difference in button labels compared to the existing Canon V10 camera.
As you can see we do have differences on the rear side of the camera too, and we have a mode dial on the rear side like a Canon Mirrorless camera instead of the old style of circular center fixed button layout like Canon V10.
More Images of the same
The upcoming model will be called Canon V100 or V10 mark II or may be Canon V1, we don’t know yet, but for sure Canon will make vlogging centered camera in near future.

In Canon’s latest patent, we can see that Canon is working to improve the low-light sensitivity of their sensors, specifically with dense photodiode architecture. This becomes particularly important when pixel sizes decrease and pixel count increases, as is the case with higher-resolution sensors. It’s a significant challenge for camera makers to maintain proper low-light sensitivity under these conditions. To overcome this, Canon is developing new technology to enhance the performance of its sensors.
Canon Latest Patent Summary
- Introducing a light shielding layer in the optical waveguide around each pixel to prevent light leakage and color mixing between pixels, and to preserve phase difference information.
- Forming an optical waveguide from near the surface of a photoelectric conversion unit to the upper end of an insulating film to prevent light scattering and absorption by wiring inside the pixel.
- Adjusting the refractive index of a non-reflective film on the bottom surface of the optical waveguide of a pixel corresponding to each color to manage variations in light receiving sensitivity between colors.

In a recent Canon patent, it is very clearly visible that Canon is working on a tilt-table viewfinder for their full-frame mirrorless camera, even camcorders. In general, once a patent surfaces on the web, it roughly takes one or two years to become a real product, specifically at least 2 years when we are talking about a Canon patent. So we have to wait for that. At the same time, it is also to be noted that not every patent becomes a real product, so you have to consider all these factors before jumping to any specific conclusion
This is not the first time someone is testing out or at least tried out a tilting viewfinder a few years back Panasonic Lumix GX 9 (Panasonic G9 Mark II Rumors) camera was one of the first compact mirrorless cameras to feature a tilting find after that Fuji also introduced a tilting viewfinder in their gfx series camera so undo not new in any way new and we have to wait to see in which model Canon introduces

- An object of the present invention is to suppress an increase in the size of an electronic device while securing a large rotation angle of a finder portion.
- Description of the Related Art
Conventionally, a viewfinder unit provided in an electronic device such as an imaging device is known. For example, in an electronic device having a viewfinder unit such as an electronic viewfinder, the viewfinder unit is arranged on the upper part of the back side of the electronic device body. The finder section of the finder unit can be slid out from the main body of the electronic device, and the finder section can be tilted and rotated upward from the pulled out state, thereby increasing the degree of freedom in shooting posture. Are known.
- [0005]However, in Patent Document 1, since the distance between the contact position of the pair of leaf springs with respect to the base plate and the rotating shaft of the holder is long, the contact position moves so as to draw a large arc locus during rotation. . If the finder section rotates excessively, the plate spring section will come off the fixed plate, so there is a restriction on the rotation angle of the finder section. On the other hand, if an attempt is made to design the rotation angle to be large, it is necessary to enlarge the fixing plate, which leads to an increase in the size of the imaging apparatus main body.
- SUMMARY OF THE INVENTION It is an object of the present invention to suppress an increase in the size of an electronic device while securing a large rotation angle of a viewfinder.

Yes, for the first time a Camera maker is working on introducing vibration mode inside the G series compact camera. I don’t know the exact reason behind this, maybe they will adopt android OS soon? So, in which mode you will put your camera, vibrate, silent or Ringing?
Patent Details [Via using Machine translation]
SUMMARY OF THE INVENTION It is an object of the present invention to provide an electronic device capable of transmitting an appropriate vibration feeling without relying on vibration-generating means even when the operation speed of an operation unit is high.
An electronic device as one aspect of the present invention includes an operation unit, a position detection unit capable of detecting an operation position of the operation unit, a vibration unit that generates vibration, and a detection signal output from the position detection unit. and a control means for controlling the driving of the vibration means based on the information about the operation of the operation section that has been received, wherein the control means controls that a predetermined operation position of the operation section is detected by the position detection. If the elapsed time from detection by means is less than a predetermined time, the vibration means is driven so that the current amplitude or frequency of vibration does not decrease, and if the elapsed time is greater than the predetermined time, the vibration means is driven. It is characterized by driving such that the current amplitude or frequency of vibration is reduced.
