The Canon EOS 5DS R emerges as the winner with a score of 68/100, while the Canon EOS 5D Mark III follows closely at 65/100. Both cameras are DSLRs and share the same dimensions of 152 x 116 x 76mm. They were released in 2012 and 2015, with launch prices of $3499 and $3900, respectively.

The 5DS R outperforms the 5D Mark III with its lighter weight of 930g, compared to the latter’s 950g. This makes it more convenient to carry around during shoots. However, the 5D Mark III has the advantage of being more affordable, with a launch price that is $401 lower than the 5DS R.

Considering these specifications, the Canon EOS 5DS R is a better camera due to its higher score and lighter weight, while the Canon EOS 5D Mark III is still a viable option for those seeking a more budget-friendly choice.

Canon EOS 5D Mark III vs EOS 5DS R Overview and Optics

The Canon EOS 5DS R emerges as the winner in optics with a score of 73/100, compared to the Canon EOS 5D Mark III’s score of 67/100. Both cameras share several specifications, such as the CMOS sensor type, full-frame sensor size, Canon EF lens mount, and lack of image stabilization. However, there are key differences that make one camera stand out over the other.

The 5DS R’s superior optics score is due to its higher megapixel count of 50.6, which results in greater image detail and larger print sizes. Additionally, the 5DS R has a higher DXOMARK score for the sensor (86) compared to the 5D Mark III’s score of 81, indicating better overall image quality. The 5DS R’s dual Digic 6 processor also contributes to its better performance in processing the high-resolution images.

On the other hand, the 5D Mark III has a faster shooting speed of 6 frames per second, making it more suitable for capturing fast-moving subjects. This advantage may be significant for photographers who prioritize action and sports photography. However, the difference in shooting speed is only a single frame per second, which may not be a substantial enough benefit for some users.

Taking these factors into account, the Canon EOS 5DS R is the better choice for photographers who value high-resolution images, better overall image quality, and advanced image processing capabilities. The Canon EOS 5D Mark III, while slightly faster in shooting speed, does not offer enough advantages to outweigh its lower optics score and fewer megapixels.

The higher the number of megapixels, the more detail the cameras sensor can capture.

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.
Minimum ISO (Native)
Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image.
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.
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.
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.

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.
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.

Canon EOS 5D Mark III vs EOS 5DS R Video Performance

The Canon EOS 5DS R narrowly wins in video capabilities with a score of 57/100, compared to the Canon EOS 5D Mark III, which has a score of 56/100. Both cameras share common features, such as Full HD video resolution and maximum video dimensions of 1920 x 1080.

The 5DS R outperforms the 5D Mark III in terms of time-lapse functionality. This feature is built into the 5DS R, allowing users to create stunning time-lapse videos without needing additional equipment or software. This advantage makes the 5DS R more versatile and convenient for capturing dynamic scenes and events.

On the other hand, the 5D Mark III has a higher maximum video frame rate of 60fps, compared to the 30fps of the 5DS R. This means that the 5D Mark III can capture smoother and more fluid motion, especially in fast-paced scenes or when recording sports events. This higher frame rate gives the 5D Mark III an edge in certain situations where capturing quick movement is crucial.

Taking these factors into account, the Canon EOS 5DS R is a better choice for those who prioritize time-lapse functionality and appreciate its convenience. However, the Canon EOS 5D Mark III is more suitable for users who require a higher frame rate for smoother video capture of fast-moving subjects. Ultimately, the choice between these two cameras should be based on the specific video requirements of the photographer.
