Some questions arose after Canon UK made a small change to the wording for the EOS R3 sensor presentation on their homepage.
Spotted by DC Life, the small change seems to mean something. As you can see in the image on top, Canon UK stated that the EOS R3 sensor was “designed and manufactured by Canon“. Canon USA and Canon Japan just stated the sensor was “developed by Canon“. A small but indeed significant difference. The best part: Canon UK changed their wording shortly after the presentation, and now it’s on line with the other Canon sites. According to DC Life the change was made on April 24. See image below.
So, without starting wild conspiracies: what’s the reason for the change in wording? What immediately comes to mind is that it might be a sensor developed by Canon and manufactures by Sony, as for instance Nikon does. Or it means Canon makes just a part of the sensor which is then assembled with parts manufactured by others. Or it might just mean nothing, a glitch in the text that has been corrected to align it with other Canon sites.
I am pretty skeptical that Canon did not made the EOS R3 sensor in house, i.e. on their own. They have the skills and capabilities. As far as I know, only certain PowerShot cameras have imaging sensors not made by Canon.
What are your ideas on this? Just a glitch, or did Canon not make the EOS R3 sensor and doesn’t want to make too much noise around it? Let us know.
Sony is set to release another innovative imaging sensor, with 128MP resolution and global shutter.
Canon is also rumored to work on an entirely new sensor. Sony, so it seems, will release its imaging sensor before Canon..

Dual Pixel AF was true innovation when first launched by Canon on the EOS 70D. It’s just common sense to assume Canon will develop it further. Welcome Quad Pixel AF.
Here is a Canon patent for a Quad Pixel AF imaging sensor, and it is not the first we spotted. Canon patent application 2020-171060 (Japan) discusses the technology. It’s hard to say when we will see the first commercial Quad Pixel AF sensor. But we know it is coming.
More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production are these:
A new super-specialised 250MP APS-H sensor from Canon is coming soon. Canon itself announced the release.
Canon Japan confirmed the market launch of this new sensor in late October 2020. The 250MP APS-H sensor will be available in both color and monochrome versions. The new sensors are named LI8020SAC (color) and LI8020SAM (monochrome). Typically, this kind of sensors are employed in scientific applications.
Canon has a long history in making multi-purpose or otherwise highly specialized cameras. It seems two more are going to be added. A few days ago two Canon multi-purpose cameras showed up at a Russian certification agency: the ML-100 and the ML-105. I wonder if this sensor will be featured on the ML-100 and the ML-105. Chances are good, in our opinion.
Presentation of the new sensor:
Here is the machine translated text from Canon Japan:
The new product is an ultra-high resolution CMOS sensor with approximately 250 million pixels, which enables you to capture detailed information in an image while shooting a wide range. In addition, by setting the pitch of one pixel to 1.5 μm (micrometer), we have achieved approximately 250 million pixels in APS-H size, making it possible to use it for various purposes. It can be used for various purposes such as FPD (flat panel display) inspection, which has become higher definition due to the development of 4K / 8K video technology, industrial inspection, video production, digital archive, wide area surveillance, microscope, etc. Meet the needs of users.
Get detailed information even in a wide range of shooting with ultra-high resolution of about 250 million pixels
The new product is capable of imaging at ultra-high resolution of about 250 million pixels, which is about 125 times that of full HD (1,920 x 1,080 pixels) and about 30 times that of 4K (3,840 x 2,160 pixels), and can be taken in any shooting range. Sufficient resolution can be obtained by trimming the area and enlarging it with an electronic zoom.
Achieves ultra-high-speed signal reading of approximately 1.25 billion pixels / second
With CMOS sensors, the amount of signal increases as the number of pixels increases, causing signal delays and slight timing deviations. The new product has an ultra-multi-pixel structure of approximately 250 million pixels, but by refining the circuit and advancing signal processing technology, it has achieved an ultra-high-speed signal readout of approximately 1.25 billion pixels per second. This enables ultra-high resolution imaging at a speed of approximately 5 frames / sec even when all pixels are read out.
Supports data output according to user needs with “ROI read function” etc.
The new product is equipped with a “ROI (Region of Interest) read function” that selectively reads only an arbitrary area. If you want to read only a specific area at high speed, you can use the “ROI read function” at 24 fps for 8K (7,680 x 4,320 pixels), 30 fps for 4K (3,840 x 2,160), and 60 fps for full HD (1,920 x 1,080). Video recording is possible. It also has a “thinning out reading function * ” that thins out the entire image area in the vertical direction to read out, so you can select the data output method that suits your needs.
*4 patterns of thinning are possible. 1/3 is about 15fps, 1/5 is about 25fps, 1/7 is about 35fps, and 1/9 is about 45fps.
Canon’ research labs are continuously pushing the technological evolution of image sensors. Here is another one.
Spotted by Image Sensors World, and none else despite what it might seem, the Canon LI7050 is a new high-sensitivity CMOS sensor for network and industrial cameras that enables full-HD color video capture in 0.08 lux environments. Not bad, eh?
Despite a compact pixel array of 1/1.8 inches and pixel size of 4.1 µm, Canon’s newly developed LI7050 sensor makes possible color video recording in low-light environments as dark as 0.08 lux.
Security cameras equipped with the LI7050 can capture video at night in such locations as public facilities, roads or transport networks, thereby helping to identify details including the color of vehicles or subjects’ clothing. What’s more, this compact, high-sensitivity sensor can be installed in cameras for such use cases as underwater drones, microscopes and wearable cameras for security personnel.
Canon’s new sensor is also equipped with an HDR drive function that realizes a wide DR of 120 dB. When recording in an environment with illumination levels between, for example, 0.08 lux and 80,000 lux, the sensor’s wide dynamic range enables video capture without blown-out whites and crushed blacks. During normal drive operation, the sensor realizes a noise level of 75 dB and captures video without blown-out whites and crushed blacks in environments with illumination levels between, for example, 0.08 lux and 500 lux.
Is there already someone claiming the sensor is overheating? If not, here is a video showing of the capabilities of this sensor. We think it’s impressing.
SINGAPORE, 3 August 2020 — Canon announced today the launch in Japan of the LI7050, a new 1/1.8-inch CMOS sensor capable of capturing color images in full-HD even in low-illumination environments as dark as 0.08 lux1.
The recent growth of IoT technologies has in turn generated increasing demand for network and industrial-use cameras—in particular, cameras capable of image capture in full-HD as well as nighttime color recording. Despite a compact body size of 1/1.8 inches and pixel size of 4.1 µm (micrometers), Canon’s newly developed LI7050 sensor makes possible color video recording in full-HD, even under low-light conditions.
The LI7050, while achieving a compact size, features a pixel architecture that enables high sensitivity, thereby making possible low-noise, full-HD color video recording in low-light environments as dark as 0.08 lux. Conventional nighttime monitoring employs infrared cameras and records video in monochrome. However, network cameras equipped with the LI7050 can capture video at night in such locations as public facilities, roads or transport networks, thereby helping to identify details including the color of vehicles or subjects’ clothing. What’s more, this compact, high-sensitivity sensor can be installed in cameras for such use cases as underwater drones, microscopes and wearable cameras for security personnel.
Canon’s new sensor is also equipped with an HDR drive function that realizes a wide dynamic range of 120 dB. When recording in an environment with illumination levels between, for example, 0.08 lux and 80,000 lux, the sensor’s wide dynamic range enables video capture without blown-out whites and crushed blacks. Thanks to this capability, the sensor enables cameras to record high-quality video, even when positioned at building entrances and other locations where there are significant variations in illumination levels. During normal drive operation, the sensor realizes a noise level of 75 dB and captures video without blown-out whites and crushed blacks in environments with illumination levels between, for example, 0.08 lux and 500 lux. The LI7050 supports the MIPI CSI-2 interface utilized by a wide range of consumer and industrial-use cameras, thereby greatly expanding the number of possible equipment combinations. The sensor also meets a variety of industrial needs through such features as a Region of Interest (ROI) function that enables users to select regions to read from the sensor, reducing the amount of read information and allowing for image capture at an increased framerate, and the ability to configure horizontal and vertical inversion directly from the sensor for easy viewing of footage from cameras installed on ceilings and other inverted positions. Canon has begun sample shipments of the LI7050 from today, and is scheduled to officially commence sales in late October 2020.
We compare 4 sensor sizes to see how they compare in print image quality: Hasselblad X1D II 50C, Sony a7R IV, Sony a6600 and Panasonic GH5. See how much difference there is in the Medium, Full-frame, APS-C and Micro 4/3 Sensors.
