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 »
Canon is at it again with this form factor and finding more ways to combat the most obscure heat problems you can imagine. Why heat is an issue, is aptly described in this part of the patent application. canonrumors.com »
Today, two more patent applications discussing quad-pixel auto-focus sensors have been published by the Japan Patent Office. The first patent application 2023-167634 deals with the fact that scan times will vary between row and column scanning, which could lead to inaccurate auto-focus performance. canonrumors.com »
A patent application (2023-166831) from Canon has just been released for improved cooling for a small form factor camera, that also includes IBIS. The form factor that Canon describes seems to be quite similar to that of the Canon R5C, but smaller. canonrumors.com »
We just went into a long discussion over why reducing heat from IBIS units is a good and absolutely necessary thing for Canon to be looking at, so I think if you need some background, have a go with this patent application here. canonrumors.com »
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 »
Asobinet spotted a new patent that would allow you to control some camera aspects through movement instead of having to operate a menu or buttons: It seems that a vibration device will be embedded in the grip. sonyalpharumors.com »
This patent application (2023-149130)shows some interesting and fairly simplistic optics for 70, 75, and 85mm primes. The 85mm primes are unlikely since we already have the Canon RF 85mm F2. 0 IS STM. canonrumors.com »
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 »
In this patent application (2023-130885), Canon lists quite a few primes with a significant ingress, but also more notably a smaller image circle than what would normally be used for APS-C. For Canon APS-C, that's 13. canonrumors.com »
I recall back to the film days and using the glorious little 55 and 56mm primes. Hardly anyone makes them anymore which I think is a sad state of affairs. Needless to say, this patent application got me a bit intrigued for that very reason. canonrumors.com »
In this Japan Patent Application, JP 2023-118490, Canon is investigating creating smaller built in teleconverters for use in lenses that we would normally not expect to see a teleconverter installed in. canonrumors.com »
