Canon EOS 5D Mark III vs EOS R6 Overview and Optics
The Canon EOS R6 outperforms the Canon EOS 5D Mark III in optics, with a score of 79/100 compared to the 5D Mark III’s 67/100. Both cameras share some similar specifications, such as the CMOS sensor type, full-frame sensor size, and megapixels, with the 5D Mark III offering 22.3 and the R6 offering 20.1. Despite these similarities, the EOS R6 surpasses the 5D Mark III in several key aspects.
The R6’s higher score stems from its faster shooting speed of 20 frames per second (fps), compared to the 5D Mark III’s 6 fps. Additionally, the R6 features a more advanced Digic X processor, resulting in improved image processing capabilities. The R6 also boasts a higher DXOMARK sensor score of 90, compared to the 5D Mark III’s score of 81, which reflects the R6’s superior image quality. Furthermore, the R6 utilizes the Canon RF lens mount and offers image stabilization, while the 5D Mark III relies on the older Canon EF lens mount and lacks image stabilization.
However, the 5D Mark III does have a slight advantage in terms of megapixels, with 22.3 compared to the R6’s 20.1. This difference may benefit photographers who require larger image sizes for printing or cropping purposes.
Taking these factors into account, the Canon EOS R6 emerges as a more advanced and capable camera in terms of optics when compared to the Canon EOS 5D Mark III. The R6’s faster shooting speed, better processor, higher sensor score, and additional features such as image stabilization make it a superior choice for photographers seeking optimal image quality and performance. While the 5D Mark III offers a slightly higher megapixel count, the R6’s other advantages outweigh this minor edge.

Megapixels The higher the number of megapixels, the more detail the cameras sensor can capture. | 22.3 MP | 20.1 MP | |
|---|---|---|---|
Image Resolution Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution. | 5760 x 3840 px | 5472 x 3648 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 | 23.9 x 35.9 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. | 6 fps | 20 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 EF | Canon RF | |
Image Processor The image processor in the camera converts the information collected on the sensor for digital storage on the memory card. | Digic 5+ | Digic 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. | 25,600 | 102,400 | |
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. | 102400 | 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. | 61 | 1,053 | |
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. | Optical (pentaprism) | Electronic | |

Canon EOS 5D Mark III vs EOS R6 Video Performance
The Canon EOS R6 outperforms the Canon EOS 5D Mark III in video capabilities, scoring 91/100 compared to the 5D Mark III’s 56/100. Both cameras share some common specifications, but the EOS R6 offers significant improvements in video quality and features.
Both the Canon EOS 5D Mark III and the Canon EOS R6 have Full HD video resolution. However, the EOS R6 also offers 4K video resolution, with maximum dimensions of 3840 x 2160, compared to the 5D Mark III’s 1920 x 1080. This means the EOS R6 provides four times the video resolution of the 5D Mark III, resulting in sharper and more detailed footage.
The EOS R6 also boasts a higher maximum video frame rate at 120fps, whereas the 5D Mark III’s maximum is 60fps. This allows the EOS R6 to capture smoother slow-motion footage and gives users more creative flexibility when shooting videos.
Additionally, the Canon EOS R6 has built-in time-lapse functionality, which the 5D Mark III lacks. This feature enables users to easily create stunning time-lapse sequences without needing additional equipment or software.
The Canon EOS 5D Mark III does not have any specific advantages in video capabilities over the EOS R6. The R6’s superior video quality, higher frame rate, and built-in time-lapse functionality make it the clear winner in this comparison.
Considering these factors, the Canon EOS R6 is the better choice for videographers and content creators who need high-quality video features. The EOS 5D Mark III, while still a capable camera, falls short in comparison to the R6’s advanced video capabilities.
