Canon EOS R6 Mark II vs Sony a7 III Overview and Optics
The Canon EOS R6 Mark II wins the optics comparison with a score of 83/100, while the Sony a7 III scores 81/100. Both cameras have similar specifications, such as 24 and 24.2 megapixels, CMOS sensors, full-frame sensor sizes, and image stabilization. They also have different lens mounts, with the Canon using an RF mount and the Sony using an FE mount.
The Canon EOS R6 Mark II outperforms the Sony a7 III in certain areas. Its shooting speed of 40 is significantly faster than the Sony’s 10, allowing for more efficient and responsive shooting. The Canon’s Digic X processor also provides faster processing and better image quality compared to the Sony’s Bionz X processor.
On the other hand, the Sony a7 III has a higher DXOMARK score for its sensor at 96, compared to the Canon’s score of 91. This means that the Sony’s sensor performs better in terms of dynamic range, color depth, and low-light performance. However, this advantage may not be significant enough to overcome the other benefits provided by the Canon EOS R6 Mark II.
In the optics comparison, the Canon EOS R6 Mark II is the better camera due to its faster shooting speed and more advanced processor. The Sony a7 III does have a slightly better sensor, but this advantage is not enough to make it the winner in this comparison. Both cameras offer excellent image quality and features, but the Canon EOS R6 Mark II’s superior performance makes it the preferred choice for photographers seeking the best optics.

Megapixels The higher the number of megapixels, the more detail the cameras sensor can capture. | 24 MP | 24.2 MP | |
|---|---|---|---|
Image Resolution Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution. | 6000 x 4000 px | 6000 x 4000 px | |
Sensor Type The camera sensor captures light and records the image. Sensors vary in physical size, the number of pixels, and quality. | CMOS | CMOS | |
Sensor Size The sensor size contributes to the overall quality as well as the dynamic and tonal range a camera can capture. As a rule of thumb, the more surface there is to read the light, the more information it will capture. | 24 x 36 mm | 23.8 x 35.6 mm | |
Sensor Format Refers to the most commonly used sensor sizes. |  Full Frame | Full Frame | |
Frame Rate The number of sequential frames per second the camera can write to the memory card when shooting in burst or continuous mode. | 40 fps | 10 fps | |
Lens Mount The lens mount will tell you what type of lens range you can fit onto the camera body. Often the same camera company will have different lens ranges for different cameras. | Canon RF | Sony FE | |
Image Processor The image processor in the camera converts the information collected on the sensor for digital storage on the memory card. | Digic X | Bionz X | |
Aspect Ratio The aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3. |  3:2 | 3:2 | |
Minimum ISO (Native) Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image. | 100 | 100 | |
Maximum ISO (Native) Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise. | 102,400 | 51,200 | |
Minimum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 50 | 50 | |
Maximum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 204800 | 204800 | |
Minimum Shutter Speed The minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory. | 30 s | 30 s | |
Maximum Shutter Speed The maximum shutter speed tells you the length inside 1 second the camera will capture. These can sometimes be extended with accessories such as extra external batteries. | 1/ 8000 s | 1/ 8000 s | |
Autofocus Points Autofocus points show where the camera is focusing graphically as squares or brackets in Live View or on an electronic viewfinder. These points are also used for light meter readings. | 4,897 | 693 | |
In-body Stabilization In-body Stabilization means the camera has a certain technology embedded that counteracts camera shake. |   | | |
Viewfinder Type The viewfinder type is either electronic or optical. Electronic viewfinders will have a small screen in the viewfinder. Optical viewfinders will use prisms and mirrors to look through the lens. | Electronic | Electronic | |

Canon EOS R6 Mark II vs Sony a7 III Video Performance
The Canon EOS R6 Mark II outperforms the Sony a7 III in video capabilities with a score of 83 compared to the Sony’s 70. Both cameras share common specifications, such as 4K max video resolution and max video dimensions of 3840 x 2160. However, the Canon EOS R6 Mark II surpasses the Sony a7 III in certain aspects, making it the winner in this comparison.
One significant advantage of the Canon EOS R6 Mark II is its max video frame rate of 60fps, while the Sony a7 III only offers a max video frame rate of 30fps. This higher frame rate allows for smoother and more detailed video capture, particularly in fast-moving scenes or when shooting slow-motion footage.
Despite its lower video score, the Sony a7 III still delivers high-quality 4K video resolution and impressive video dimensions. However, its lower frame rate and lack of built-in time-lapse functionality give the Canon EOS R6 Mark II a clear advantage in terms of video capabilities.
