The Canon EOS R6 outperforms the Canon EOS 1D X Mark III with a score of 80/100 compared to 75/100. Both cameras were released in 2020, with the EOS R6 being a mirrorless model and the 1D X Mark III being a DSLR. They share common specifications, such as announcement and release years.
The EOS R6 excels due to its lighter weight of 680g and smaller size of 138 x 98 x 88mm, making it more portable. Additionally, it has a significantly lower launch price of $2499, making it a more budget-friendly option.
On the other hand, the 1D X Mark III has a slightly larger size of 158 x 168 x 83mm and heavier weight of 738g. Despite this, it remains a worthy competitor in the market.���
Considering these factors, the Canon EOS R6 is the better choice for those seeking a more portable and affordable camera, while the Canon EOS 1D X Mark III remains a reliable option for those who prefer DSLR cameras.
The Canon EOS R6 wins in optics with a score of 79/100, while the Canon EOS 1D X Mark III scores 74/100. Both cameras share several specifications, including 20.1 megapixels, a shooting speed of 20, CMOS sensor type, Digic X processor, full-frame sensor size, and similar DXOMARK scores for the sensor (91 for 1D X Mark III and 90 for R6).
The R6 outperforms the 1D X Mark III in terms of optics due to its Canon RF lens mount and built-in image stabilization. The Canon RF lens mount allows for compatibility with the latest Canon RF lenses, which offer improved optical performance and features. The image stabilization feature in the R6 ensures sharper images, especially when shooting handheld or in low-light conditions.
On the other hand, the 1D X Mark III has a slightly higher DXOMARK score for the sensor, but this minimal difference does not significantly impact image quality. The 1D X Mark III uses the Canon EF lens mount, which offers a wide range of lenses but lacks the advancements found in the newer Canon RF lenses.
In terms of optics, the Canon EOS R6 is the superior choice due to its compatibility with cutting-edge Canon RF lenses and built-in image stabilization. The 1D X Mark III falls short in these aspects, making the R6 a better option for photographers seeking the best optical performance. However, the 1D X Mark III remains a strong contender with a vast selection of Canon EF lenses and a marginally higher sensor score.
The Canon EOS 1D X Mark III and Canon EOS R6 are evenly matched in their video capabilities, both receiving a score of 91 out of 100. They share several common specifications, such as 4K video resolution, a maximum video frame rate of 120fps, and built-in time-lapse functionality.
Despite the same video score, the Canon EOS 1D X Mark III has a slight edge over the EOS R6 in terms of video dimensions. It offers a maximum video dimension of 4096 x 2160, whereas the EOS R6 has a slightly lower maximum video dimension of 3840 x 2160. This difference in video dimensions results in a slightly higher quality video output for the 1D X Mark III, making it a better choice for those seeking the best video resolution.
On the other hand, the Canon EOS R6 has no specific advantage over the 1D X Mark III in terms of video capabilities. However, it is essential to consider other factors, such as price, size, and weight, which may influence the buyer’s decision.
Given the similarities in video scores and capabilities, both cameras are suitable for individuals looking to capture high-quality video content. The Canon EOS 1D X Mark III is the better choice for those prioritizing the highest video resolution, while the Canon EOS R6 remains a strong contender, especially when taking into account factors beyond video performance.
The Canon EOS R6 wins the feature comparison with a score of 85/100, while the Canon EOS 1D X Mark III scores 74/100. Both cameras share some common specifications, such as a touchscreen, WiFi connectivity, and similar screen sizes (3 inches for the R6 and 3.2 inches for the 1D X Mark III).
The EOS R6 outperforms the 1D X Mark III with its flip screen and Bluetooth connectivity. The flip screen provides flexibility for various shooting angles and is especially useful for vlogging or self-portraits. Bluetooth allows for seamless file transfer and remote control of the camera, enhancing its usability.
On the other hand, the 1D X Mark III has a higher screen resolution of 2,100,000 dots compared to the R6’s 1,620,000 dots. This results in a sharper and clearer display, which can be helpful when reviewing images or navigating menus. Additionally, the 1D X Mark III includes GPS functionality, allowing for precise location tracking and geotagging of images – a feature unavailable on the R6.
While the EOS R6 is the winner in terms of features, the 1D X Mark III’s advantages in screen resolution and GPS should not be overlooked. Photographers who prioritize a sharper display and location tracking may prefer the 1D X Mark III. However, those who value the flexibility of a flip screen and the convenience of Bluetooth connectivity will find the EOS R6 more suitable.
The Canon EOS 1D X Mark III outperforms the Canon EOS R6 in storage and battery, scoring 87/100 compared to the R6’s 68/100. Both cameras have two memory card slots, but the 1D X Mark III accepts CFexpress Type B cards, while the R6 takes SD/SDHC/SDXC (UHS-II compatible) cards. The 1D X Mark III boasts a significantly longer battery life, with 2850 shots per charge using the LP-E19 battery, as opposed to the R6’s 360 shots with its LP-E6NH battery.
However, the R6 does offer USB charging, which the 1D X Mark III lacks. This feature provides added convenience for users who need to charge their camera on-the-go.
Considering these factors, the Canon EOS 1D X Mark III excels in storage and battery performance, offering a longer-lasting battery and support for faster memory cards. The Canon EOS R6, while having a shorter battery life and slower memory cards, benefits from the convenience of USB charging.
