The Canon EOS R5 outperforms the Canon EOS 1D X Mark III with a score of 86/100 compared to 75/100. Both cameras were released in 2020 and share some specifications, such as being produced by Canon and having similar dimensions. The R5 has the advantage of being a mirrorless camera, making it lighter at 680g compared to the 1D X Mark III’s 738g. Additionally, the R5 has a lower launch price of $4499 versus the 1D X Mark III’s $6500.

The 1D X Mark III, as a DSLR, has its own merits, but the R5 proves to be a better choice due to its higher score, lighter weight, and more affordable price. Both cameras have their strengths, but the Canon EOS R5 stands out as the winner in this comparison.

Canon 1D X Mark III vs R5 Overview and Optics

The Canon EOS R5 takes the lead in optics with a score of 88/100, while the Canon EOS 1D X Mark III trails with a score of 74/100. Both cameras share several specifications, including a CMOS sensor, Digic X processor, shooting speed of 20 frames per second, and full-frame sensor size.

The EOS R5 outperforms the 1D X Mark III in several aspects. It boasts a higher megapixel count at 45, compared to the 1D X Mark III’s 20.1, resulting in better image resolution. Additionally, the R5 has a superior DXOMARK sensor score of 95, compared to the 1D X Mark III’s 91, indicating improved overall image quality. The R5 also features image stabilisation, which the 1D X Mark III lacks, allowing for steadier shots and better low-light performance. Furthermore, the R5 uses the Canon RF lens mount, which offers a wider range of modern lenses with improved optical performance.

On the other hand, the 1D X Mark III uses the Canon EF lens mount, which provides access to a vast selection of lenses, including older and more affordable options. This can be an advantage for photographers with an existing collection of EF lenses or those on a budget.

To sum up, the Canon EOS R5 excels in image resolution, sensor performance, and lens compatibility, making it the superior choice for photographers prioritising optics. However, the Canon EOS 1D X Mark III offers compatibility with a broader range of lenses, which can be beneficial for photographers with existing EF lenses or budget constraints.

Canon 1D X Mark III vs R5 Video Performance

The Canon EOS R5 emerges as the winner in video capabilities with a score of 100/100, while the Canon EOS 1D X Mark III scores 91/100. Both cameras share some common specifications, including a maximum video frame rate of 120fps and built-in time-lapse functionality.

The Canon EOS R5 outperforms the Canon EOS 1D X Mark III in terms of video resolution and dimensions. The R5 boasts an impressive 8K maximum video resolution (8192 x 4320), which is notably higher than the 1D X Mark III’s 4K maximum video resolution (4096 x 2160). This difference allows the R5 to produce videos with higher image quality and detail, making it a more suitable option for professional videographers.

The Canon EOS 1D X Mark III, despite having a lower video score, still offers solid video capabilities. It can capture high-quality 4K videos, which are sufficient for most users and purposes. However, when compared to the R5, it falls short in terms of resolution and detail.

Taking these factors into account, the Canon EOS R5 is the superior choice for filmmakers and videographers seeking top-of-the-line video capabilities. Its 8K maximum video resolution and larger dimensions provide a significant advantage over the Canon EOS 1D X Mark III. That being said, the 1D X Mark III remains a viable option for those who do not require the highest possible video resolution and are content with 4K quality.

Canon EOS 1D X Mark III vs EOS R5 Features and Benefits

The Canon EOS R5 wins the features comparison with a score of 87/100, while the Canon EOS 1D X Mark III scores 74/100. Both cameras share several specifications, including a 3.2-inch screen size, 2,100,000-dot screen resolution, touchscreen, and WIFI connectivity.

The EOS R5 outperforms the 1D X Mark III in two key areas. Firstly, it has a flip screen, which allows for more versatile shooting angles and better framing, particularly for vlogging or self-portraits. Secondly, the R5 features Bluetooth connectivity, enabling easier and more efficient pairing with smartphones and other devices for remote control and image transfer.

On the other hand, the 1D X Mark III has GPS functionality, which the R5 lacks. This feature allows photographers to geotag their images, making it easier to organize and locate photos based on the shooting location. The GPS feature is particularly beneficial for wildlife, landscape, and travel photographers who need precise location data.

In conclusion, the Canon EOS R5 offers more advanced features, such as a flip screen and Bluetooth connectivity, which make it a better choice for photographers who prioritize versatility and ease of use. However, the Canon EOS 1D X Mark III’s GPS functionality provides an advantage for those who require geotagging capabilities. Ultimately, the choice between these two cameras will depend on the specific needs and preferences of the photographer.
