A newly discovered Canon patent illustrates the lengths that companies are considering when it comes to cooling the latest and greatest camera gear. In this case: a detachable fan that replaces the optical viewfinder of a 1D X-like DSLR.
The patent was unearthed by Canon News, who speculates that it may have been something the […]. petapixel.com
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 »

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 »

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 »

Okay, I know this is beating a dead horse as a matter of fact, the horse has been beaten to death, dragged off, and turned into glue already.

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 »

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 »

Over the years I've seen some crazy designs patented by Canon and applications like this one are fun to read. I mean, here's a patent application where someone was told. “Go nuts, see what you can do”. 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 »

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. canonrumors.com »
2023-09-28 14:08
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 »

There are times I see a cool patent, and look at it and can't for the life of me explain what it does. I still may have gotten this one wrong, but I don't think so. I actually sat on this patent all weekend and even forced Craig into an Irish triple expresso before finally [. canonrumors.com »

Thanks to improvements in sensor design, iPhone and Android smartphones are gaining traction with enthusiast and professional creators. However, one area that has lagged behind developments in imaging sensors is image stabilization.
This patent application (Japan 2023-125903) has a lot of esoteric fast zoom lenses in some very nontraditional focal lengths. Many of the embodiments are missing the image height, however since we also have the half angle of view, we can work backward to verify if these lenses are meant for full frame or for APS-C.
Canon has filed a patent in Japan that shows what appears to be a compact built-in teleconverter that relies upon external controls and internal actuators to provide photographers with quick access to various focal lengths. [Read More]
