Canon has filed a new patent in Japan that aims to reduce the vibrations caused by a mechanical shutter. Japanese patent application number 2022-039332 outlines the issue of shutter shock and proposes a novel design that uses electromagnets to increase the precision of shutter position and control the shutter's speed to reduce shutter shock. dpreview.com »

Engineers with Tohoku University have detailed a new project in which a CMOS sensor with a global shutter is able to record ultra-high-speed footage without the constraints of existing technology, namely short-duration recording and low resolutions. dpreview.com »

Canon announced today that it has developed a CMOS sensor with a global shutter, perhaps paving the way to future Canon DSLRs that don’t suffer from the “rolling shutter” effect. CMOS sensors have come to dominate the consumer camera industry in recent times, offering a cheaper product compared to CCD sensors. However, one advantage that […] petapixel.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 [...]
