The Canon EOS 1D X Mark III outperforms the Canon EOS 5DS R with a score of 75/100 as opposed to 68/100. Both cameras are DSLRs, and they share common specifications, such as camera type and manufacturer. The 1D X Mark III, released in 2020, has a launch price of $6500 and boasts a compact size of 158 x 168 x 83mm, with a lightweight build of 738g (1.63lbs).
On the other hand, the 5DS R, released in 2015, has a more affordable launch price of $3900 but is larger at 152 x 116 x 76mm and heavier, weighing 930g (2.05lbs). Despite its lower score, the 5DS R still offers quality performance for its price. Ultimately, the 1D X Mark III’s higher score reflects its superior features and newer technology, making it the better camera choice, while the 5DS R is a more budget-friendly option for those seeking a quality DSLR.
The Canon EOS 1D X Mark III narrowly wins in the optics category with a score of 74/100, compared to the Canon EOS 5DS R’s score of 73/100. Both cameras share several common specifications, such as the CMOS sensor type, full-frame sensor size, Canon EF lens mount, and the lack of image stabilization.
The 1D X Mark III has some advantages over the 5DS R. It boasts a faster shooting speed of 20 frames per second (fps) compared to the 5 fps of the 5DS R, allowing for better capture of fast-moving subjects. The 1D X Mark III also has a higher DXOMARK sensor score of 91, compared to the 5DS R’s 86, indicating better overall image quality and low-light performance. Additionally, the 1D X Mark III utilizes the more advanced Digic X processor, which contributes to faster processing and better overall performance.
On the other hand, the 5DS R has a significant advantage in terms of megapixels, with its 50.6-megapixel sensor offering more than double the resolution of the 1D X Mark III’s 20.1-megapixel sensor. This allows for greater detail and larger print sizes when using the 5DS R. However, the 5DS R’s Dual Digic 6 processor is older and slower compared to the 1D X Mark III’s Digic X processor.
Taking these factors into account, the Canon EOS 1D X Mark III is the better choice for those who prioritize shooting speed and overall performance, while the Canon EOS 5DS R is more suitable for photographers who require high-resolution images. Both cameras offer excellent optics, but their strengths cater to different needs and preferences.
The Canon EOS 1D X Mark III outperforms the Canon EOS 5DS R in video capabilities, with a video score of 91/100 compared to the 5DS R’s score of 57/100. Both cameras share time-lapse functionality built in, which is a useful feature for creating dynamic videos.
The 1D X Mark III excels in video resolution and frame rate. It offers 4K video resolution (4096 x 2160), which is significantly higher than the 5DS R’s Full HD (1920 x 1080) resolution. This difference allows the 1D X Mark III to capture more detail and produce sharper videos. Additionally, the 1D X Mark III has a max video frame rate of 120fps, which is four times faster than the 5DS R’s 30fps. This higher frame rate enables the 1D X Mark III to record smoother videos and capture fast-moving action with greater precision.
While the 5DS R falls short in resolution and frame rate, it still offers time-lapse functionality, matching the 1D X Mark III in this aspect. However, it does not surpass the 1D X Mark III in any video-related specifications.
Considering the significant difference in video scores and the superior specifications of the 1D X Mark III, it is evident that this camera is the better option for videographers. The 4K resolution and faster frame rate make it ideal for capturing high-quality, professional-grade videos. Meanwhile, the 5DS R may be suitable for casual video use, but it cannot compete with the 1D X Mark III in terms of video performance.
The Canon EOS 1D X Mark III emerges as the winner in the features category, with a score of 74 out of 100 points, while the Canon EOS 5DS R trails behind with a score of 59. Both cameras share some common specifications, including a 3.2-inch screen size and the absence of a flip screen. However, the similarities end there, as the 1D X Mark III outperforms the 5DS R in various aspects.
One significant advantage of the 1D X Mark III is its superior screen resolution, boasting 2,100,000 dots as opposed to the 5DS R’s 1,040,000 dots. This results in a sharper and clearer display, which is essential for photographers when reviewing captured images. Additionally, the 1D X Mark III features a touchscreen, while the 5DS R does not. This allows for easier navigation and quicker adjustments to settings.
The 1D X Mark III also surpasses the 5DS R in connectivity features, as it includes both GPS and WIFI capabilities. This makes it simpler for photographers to geotag their images and transfer files wirelessly. On the other hand, the 5DS R lacks these features, which may limit its convenience and ease of use.
Despite its lower feature score, the 5DS R still stands as a reliable camera, although it does not offer any significant advantages over the 1D X Mark III in this category. The 1D X Mark III’s higher score reflects its enhanced features, making it a more versatile and user-friendly option for photographers.
The Canon EOS 1D X Mark III outperforms the Canon EOS 5DS R in storage and battery with a score of 87/100 compared to 65/100. Both cameras share similarities such as featuring two memory card slots and lacking USB charging capabilities.
The 1D X Mark III excels with its superior battery life of 2850 shots and compatibility with CFexpress Type B memory cards, which offer faster read and write speeds. This camera uses the LP-E19 battery type, contributing to its extended battery life.
On the other hand, the 5DS R has a shorter battery life of 700 shots and uses the LP-E6 battery type. However, it accepts a wider variety of memory cards, including SD/SDHC/SDXC (UHS-I compatible) and Compact Flash. This flexibility may be advantageous for some photographers.
Considering these factors, the 1D X Mark III stands out for its impressive battery life and faster memory card compatibility, while the 5DS R offers greater memory card versatility.
