This is an interesting patent application (2025-012993) showing a strange lens configuration. The embodiments show a potential RF fish eye zoom, even though that is not the focus of the patent application.
By inserting a lens grouping identified as (LC) into the lens, Canon is able to reduce the distortion. For this to work, seemingly [. . . ]

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 »

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 »

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 »
2024-01-13 09:39
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 »
2023-12-28 11:03
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 »

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 »

In this patent application (2025-023282), Canon is looking to make the power zoom motors much smaller for future lenses. Canon is exploring using 1, 2, or even more voice coil motors to move the elements necessary to zoom the lens.
In this patent application (2025-019790), Canon explores the use of more resin elements to make up some pretty interesting lenses. We have to preface this by saying that a lot of Canon lenses have resin elements; it is not unheard of, even in the realms of L lenses.
In this patent application (2025-001041), Canon describes improvements to how dual lens VR lenses focus and calibrate the focus across both lenses. This series of patents (there have been a few) made me marvel at how much we take for granted with our stereoscopic lenses – our eyes- and how seamlessly they adjust independently without [.
