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.
I swear I went through 5 copies until [. . . ]

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.
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 [...]
In this patent application (2024-072582) Canon discusses improving the magnets that drive the motors on various lenses that attach to the camera. This is to prevent the magnetic flux from causing image artifacts especially at high ISO when the sensor is operating at a extremely high level of amplification and thus, sensitivity. I seem to [...]
