In this patent application (2024-163673), Canon is exploring some lesser-quality super telephoto primes. Could be good news for us peons that don't want to drop 5 digits on a super-telephoto prime.
The designs seem interesting, yet simplistic, so I wouldn't necessarily expect these lenses to cost that much. Canon RF 400mm F4. 0 In this first [. . . ]

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 »

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 [.
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. [...] Source
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
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.
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.
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.
