This patent application (2024-101645) has a bunch of embodiments, allowing us to frame some observations about optical designs that we occasionally see here. It seems very likely that the first embodiment in this patent application is the RF 10-20mm f/4L IS STM. canonrumors.com »
In this patent application (2024-099414), Canon is showing off some interesting embodiments to some inner zoom / inner focus lenses for both full frame and crop cameras. The half-image heights are smaller for both full frame and APS-C and curiously, for all focal lengths. canonrumors.com »
This is an interesting patent application (2024-090359) that is meant to patent some designs that are superficially meant for power zoom-capable lenses. The embodiments display both crop (assuming RF-S) and full-frame lenses. canonrumors.com »
This is an interesting patent application (2024-090416) with some curious lens designs. What struck me mostly was that there seemed to be odd consistencies that you don't usually see in Canon patent application embodiments such as most of the lenses all the exact same size (95. canonrumors.com »
At first, when I was writing up this patent application (2024-082112), I was leaning toward what others are mentioning on the internet that these are for ILC (interchangeable lens cameras) but after reading more, and looking at the back focus distances involved, I think it's more likely that these are for a compact rangefinder styled [...] 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 »
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 »
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 »
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 »
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 »
In this patent application (2024-072582) Canon discusses improving the magnets that drive the motors on various lenses that attach to the camera.

I seem to [...] canonrumors.com »
In this patent application (2024-071858) Canon looks to improve the operation of IBIS on your cameras near and dear to your heart. While we'll never know if this patent will end up in the R1 or the R5 Mark II, all these types of patents silently make the little improvements that ultimately add up to [...] 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 »
In this patent application (2024-071267) Canon shows off a pretty awesome embodiment of a fabled Canon RF 14-20mm F2. 0. We were rumored to see such a lens, but with Canon's supply issues, your guess is as good as mine if it's coming soon. canonrumors.com »
In this patent application (2024-063513), Canon is looking at improving the subwavelength coatings for optical elements. In an optical system constituted by optical elements, reflection of incident light on the surface and inner surface of the optical element is undesirable because it causes a loss in the amount of transmitted light and reflection ghosts. canonrumors.com »
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 »
In this patent application (2024-061921), Canon is showing off some curious embodiments for some prime lenses. These are full-image circle primes with no image stretching so understandably they would be targetted as higher-end primes. canonrumors.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 »
Canon has been exploring quite a bit of methods of doing tilt in a more automated fashion, from having the lens electronically controlled to this patent application (2024-057829) that has the tilt movement controlled inside the camera itself. canonrumors.com »
In this patent application (2024-056859) Canon is looking at improving the reliability of an SPAD sensor. A SPAD (Single Photon Avalanche Diode) sensor, operates by putting the diode into, yes, you guessed it – avalanche mode. canonrumors.com »
In this patent application (2024-055909) Canon discusses quite a few embodiments of an dual fisheye 3D/VR lens similar to the RF5. 2mm f/2. 8L Dual Fisheye. The one of interest, is the APS-C embodiment as it's one that is rumored to be coming out soon. canonrumors.com »
We will be releasing an upcoming series of articles on infrared photography that I've been slowly working through the last few weeks, and this amusingly popped up in the list of patent applications published. canonrumors.com »
In this patent application (2024-053967) Canon is looking to improve the ability of the cameras to calibrate the eye control focus with the photographer. The eye control focus is featured on older EOS film cameras and more notably, the Canon EOS R3. canonrumors.com »
In this patent application (2024-052498) Canon discusses replacing the gel filter at the back of a dual fisheye lens with something a little more robust and user-friendly. As you may know, the Canon RF 5. canonrumors.com »
In this patent application (2024-052503), Canon is looking at providing autofocus for dual lenses, such as the Canon RF5. 2mm f/2. 8L Dual Fisheye lens. The current dual fisheye lens is manual focus only, so this would be a step in the right direction. 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 (2024-043481), Canon looks to improve the molded glass aspherical lens resin. According to Canon, the resins usually have a more difficult time with high humidity, as the optical performance changes with humidity. canonrumors.com »
It's been a slow month patent application-wise, unless, as I told Craig earlier, I start to talk about printer patent applications. No one wants to do that – including yours truly. In this patent application (JP2024-042622), Canon talks about some Ultra-wide full-frame zooms. 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 (JP2024-039231), Canon discusses a new element composition, which is a resin element attached to a glass element to form a unique composite element. This element's goal is to help reduce lens size and also decrease aberrations. canonrumors.com »
This patent application (2024-025274) discusses how to automate the tilt movement given the objects that the user wants in focus, but more importantly when you want to tilt the plane of focus to something other than horizontal or vertical. 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 »
In this patent application (2024-023099) Canon describes quite a few different full-frame super ultra-wide zoom lenses. Now with Canon just having released the pretty incredible Canon RF 10-20mm f/4 L IS STM, this is probably some of Canon's prior research that happened with that lens. canonrumors.com »
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 »
In this patent application (2024-019961) Canon shows off a high-speed stacked sensor using three substrate layers. As you can imagine, sensor layers are like a house, the more floors you have the more flexibility you have, and the more room. canonrumors.com »
In this patent application (2024-010559), Canon explores some new designs for macro lenses. With the Canon RF 100mm f/2. 8L Macro IS USM, any of the longer focal length designs are unlikely to reach production. canonrumors.com »
In this patent application (2024-007656), Canon looks to create small ultra wides for both full frame and crop. One of the designs is curiously either similar or is the RF-S 10-18mm f/4. 5-6. 3. If it is the actual RF-S 10-18, then it also gives us the lowest back focus distance for the RF mount that Canon [. canonrumors.com »
In this patent application (2024-009238) we have a series of telephoto primes for the RF mount. We know these are specifically for the RF mount because the back focus distance is under 44mm. Also, with a more relaxed back focus distance (greater than 20mm) they should work with Canon's tele-extenders. 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 »
This is an odd patent application (2024-006604), let's dive into the dirty details. These embodiments are odd for several reasons. The 18mm image height lenses would have to have an extreme amount of image stretching for full frame. canonrumors.com »
Canon never fully completes something and is always looking at methods to improve the technology they have developed. In this patent application (2024-003432), Canon is looking to improve Eye Control AF's functions. canonrumors.com »
This is a curious patent (Japan Patent Application 2024-002151). When I was quickly culling through the applications my first thought was that it was a curved sensor, but reading more it became a far more curious application. canonrumors.com »
One of the disappointments for me with the RF-S system is the normal kit zoom range from 18-45 instead of 15-45mm. In this patent application, Canon sets out to create a 15-45mm that hopefully isn't plagued with the same quality assurance issues as its older EF-M brother. 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 »
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 »
In this patent application, Canon describes setting lens barrel button functions based on the orientation of the camera body. The idea that they are batting around is that as you change the orientation and you are hand holding a heavy lens, the buttons can be then in an awkward position when you are trying to [. canonrumors.com »
In this patent application (Japan 2023-178037) Canon is describing a tilting EVF for a mirrorless camera. I had the EVF-DC1 for the EOS-M system and loved the tilt function of the EVF. It gave a different perspective and shooting angle and was a useful feature. canonrumors.com »
