One of the main complaints about using ultra-fast lenses is that you can't use the lenses easily wide open in bright sunlight. This is especially true when it comes to video and the use of more limited shutter speeds.
In this series of patent applications, Canon is discussing adding a mechanically actuated ND (Neutral Density) [. . . ]

In these two patent applications, Canon is exploring adding haptic feedback into the grip surface of the camera. These are two separate patent applications but discuss similar functions, so I'll lump them all in here. canonrumors.com »

A couple of patent applications caught my eye over the last week – and of course, with me traveling and living out of a suitcase right now I filed it in my head to revisit. These two patents show some unique pixel structures that we are not used to seeing from Canon. canonrumors.com »

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 [...]
