The Canon EOS R outperforms the Canon EOS 5D Mark III with a score of 74/100 compared to the latter’s 65/100. Both cameras share some similarities, such as being part of the Canon EOS series and having a full-frame sensor. However, the EOS R, a mirrorless camera, has several advantages. It is lighter, weighing 485g compared to the 5D Mark III’s 950g, and more compact, with dimensions of 136 x 98 x 84mm versus the 5D Mark III’s 152 x 116 x 76mm. Moreover, the EOS R offers a lower launch price of $2300, while the 5D Mark III was initially priced at $3499.
On the other hand, the 5D Mark III, a DSLR camera, has its own benefits. It was released in 2012, providing users with a longer track record and more established reputation. Despite having a higher score, the EOS R does not necessarily make the 5D Mark III obsolete. Both cameras serve different purposes and cater to different preferences. Ultimately, the choice between the Canon EOS R and Canon EOS 5D Mark III depends on the individual photographer’s needs and priorities.
Canon EOS 5D Mark III vs EOS R Overview and Optics
The Canon EOS R emerges as the winner in optics with a score of 73/100, outperforming the Canon EOS 5D Mark III, which scored 67/100. Both cameras share some common specifications, including a CMOS sensor, full-frame sensor size, and an absence of image stabilization.
The EOS R excels with its higher megapixel count of 30.3, compared to the 5D Mark III’s 22.3 megapixels. This increased resolution allows for more detailed and sharper images. Additionally, the EOS R boasts a superior shooting speed of 8 frames per second versus the 5D Mark III’s 6 frames per second, enabling better capture of fast-moving subjects. Furthermore, the EOS R’s Digic 8 processor and higher DXOMARK sensor score of 89 contribute to improved overall image quality and performance.
However, the 5D Mark III has its advantages as well, particularly in terms of lens compatibility. The camera uses the Canon EF lens mount, which supports a vast range of lenses. On the other hand, the EOS R utilizes the newer Canon RF mount, which has a more limited lens selection at present.
In terms of optics, the Canon EOS R outperforms the 5D Mark III with its higher resolution, faster shooting speed, and better overall image quality. Nevertheless, the 5D Mark III may still appeal to those who prioritize lens compatibility and the availability of a wider selection of lenses.

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 8 | |
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 | 40,000 | |
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 | 102400 | |
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 | 5,655 | |
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 R Video Performance
The Canon EOS R outperforms the Canon EOS 5D Mark III in terms of video capabilities, scoring 70 out of 100 compared to the 5D Mark III’s score of 56. Both cameras share some common specifications, such as the ability to record video at high frame rates. However, the EOS R has several advantages over the 5D Mark III, which contribute to its higher score.
One of the key differences between the two cameras is their maximum video resolutions. The EOS R can record 4K video with dimensions of 3840 x 2160, while the 5D Mark III is limited to Full HD with dimensions of 1920 x 1080. This means that the EOS R can capture more detail in its videos, making it a better choice for those who prioritize video quality. Additionally, the EOS R has built-in time-lapse functionality, which allows users to create stunning time-lapse videos without the need for additional equipment or software.
Despite these advantages, the 5D Mark III does have one edge over the EOS R: its maximum video frame rate. The 5D Mark III can record video at up to 60fps, while the EOS R is limited to 30fps. This higher frame rate allows for smoother video playback and can be beneficial for certain applications, such as sports or action photography.
Taking all of these factors into consideration, the Canon EOS R is the clear winner in terms of video capabilities. Its higher resolution and built-in time-lapse functionality make it a more versatile option for videographers. However, the 5D Mark III’s higher frame rate may still be appealing to some users, depending on their specific needs.
