Canon has published a series of 3 patent applications at the same time dealing with super-telephoto zooms. I know we have recently covered a similar patent application not so long ago, and that usually precludes me from writing up yet-another-article on this.
Personally, I'm always curious when they do multiple submissions at the same time. [. . . ]
The post Canon Patent Application: More Super Telephoto Zooms appeared first on Canon Rumors Buyers Guide.

The thermal hurdles engineers must overcome become even more significant as cameras get increasingly more robust video recording features. A new Canon camera patent hopes to overcome these concerns through a relatively compact active cooling system to keep internal recording media cool. [Read More] petapixel.com »

About 4 years ago, Canon trolled me with a series of patent applications describing a handheld interchangeable lens camera attached to a handheld gimbal system. It appeared as if Canon was thinking about taking the EOS-M in a different direction. canonrumors.com »
2024-08-23 10:27
In this patent application (2024-111453), Canon explores the super telephoto zooms that ended up with the Canon RF 200-800mm f/6.3-9 IS USM. However, there are some other interesting designs in here worth exploring so let's go through them and you'll have to tell me if Canon should have gone for broke and made a 200-1000mm.

If there's one thing I've heard mention quite a bit is people's wish for a long focal length macro lens. In this patent application (2024-103311), Canon is exploring just that. I haven't seen many patent applications in this category, so maybe it's a sign of good things to come. According to Canon; In optical systems [...] Source canonrumors.com »

In this patent application (2024-078721), Canon is showing off some embodiments of some smaller standard F2. 8 zooms. While at first glance, this seems unlikely we should also keep in mind that Tamron's smaller 28-70 F2. canonrumors.com »
2024-06-13 17:09
This is the patent application (2024-079936) that shows off the Canon RF 24-105 F2. 8 Z lens, so it's unknown if this was a one-and-done patent application and the rest of the embodiments will never come out. canonrumors.com »
2024-06-13 16:30
In this patent application (2024-076793), Canon shows off some embodiments of some lenses with internal zoom and focusing. The first embodiment that I'm going to talk about is a constant 60mm in lens length and a constant F4 aperture 12-30mm lens. canonrumors.com »
2024-06-08 19:08
This is an intriguing patent application (2024-074321) because there are a few different embodiments that deserve a closer look than I originally thought reading through it. First, the 20-60mm F2. 8 would cover a lot of focal length bases for me. canonrumors.com »
2024-05-31 06:57
In this patent application (2024-073200) Canon is looking at improving the racking of the lens from near to far to find focus quicker. As you may be aware, major defocus happens when the contrast is too far out of focus that it's just soft with no visible contrast. When this happens, it's nearly impossible for [...] canonrumors.com »

Canon has always delivered great bang for the buck lenses on top of the fabulous L lenses that we enjoy, so it's no surprise that we see a new patent application dealing with the lower end of the spectrum. canonrumors.com »
2024-05-28 10:09
This is more for your curiosity because this isn't for an upcoming product, but one in which has already been released by Canon. But some of you may be interested in seeing some of the background that goes into making such a lens in the Canon universe. canonrumors.com »
2024-05-12 15:54
There's always the feeling I get when the amount of patent applications start to reach a tempo that perhaps it's a sign that Canon is about to do something. Mind you, Canon has trolled me in the past with this, so anything is possible. canonrumors.com »

In this patent application (2024-043295), Canon is concerned about the AF performance of fast tilt-shift lenses. It seems that the incidence angle of light hitting the pixel will cause issues with AF performance around the periphery – especially when the plane of focus is tilted. canonrumors.com »
2024-04-01 07:40
In this patent application (2024-039230), Canon is looking at methods of cooling a hybrid speedlite capable of both continuous and flash lighting. As with most speedlites in the modern era, heat is the biggest problem facing speedlites. canonrumors.com »
2024-03-22 12:37
In this patent application (2024-025100), Canon describes the optical formulas of some pretty impressive zoom lenses. In this patent, we see the impressive Canon RF 24-105 F2. 8L IS USM Z embodiment, and it's just as impressive as the lens is in real life. canonrumors.com »
2024-02-26 07:29
Reading through this patent application (2024-022343) was a “huh, I never thought of that” moment. Canon in this patent is concerned that when some of its high-speed sensors go full out, they draw too much current from the battery causing the voltage to dip. canonrumors.com »

Back in the Canon EOS EF days, Canon made several large super zooms, mainly the Canon EF 100-300mm f/5. 6L, and the Canon EF 35-350mm f/3. 5-5. 6L USM. But outside of the consumer Canon RF 24-240mm f/4-6. canonrumors.com »
2024-01-18 09:41
In this patent application, Canon is illustrating some smaller primes. Since these designs are relatively simplistic, they could be good “bang for the buck” lenses as long as you are not expecting pristine resolving power, as they don't optically fill the entire image circle but rely on software stretching. canonrumors.com »
2023-12-27 14:43
When we were first discussing the series of patent applications on motorized tilt-shift lenses for the RF mount, one of my musings was the ability to use this to automate stitching and various shooting at different shifts and tilts. canonrumors.com »

Do you remember those two patent applications here and here that we talked about Canon looking at doing motorized tilt and shift with the possibility of fine AF control as well? Well, those patent applications were based on a different kind of tilt-shift lens, which involved moving elements instead of shifting and swinging the entire [. canonrumors.com »
2023-11-09 18:00
In this Canon Patent Application (2023-153460) Canon discusses both the need and the method of changing focusing during shift or tilt operations. As with the other patent applications in this series, I should first mention that the tilting and shifting discussed seem to be internal and done by moving optical elements. canonrumors.com »
2023-10-18 12:26
We recently discussed the patent here that talked about a motorized tilt-shift lens. It was my imagination that Canon could expand the functionality far beyond simply lens control. Well, it turns out the smart minds at Canon thought the same. canonrumors.com »
2023-10-04 11:36
This Canon patent application delves into the operation of a motorized tilt-shift lens for what appears like the Canon RF mount. Tilt-shift lenses have complicated and fragile mechanics, and removing some of the fiddly nature from these lenses would help in the field if the ergonomics of controlling the lens were fair. canonrumors.com »
