They also have similar megapixel counts, with the Canon EOS R5 having 45 megapixels and the Sony a7R III having 42.4 megapixels.

The Canon EOS R5’s higher score is due to its faster shooting speed and advanced processor. It has a shooting speed of 20, which is double that of the Sony a7R III’s 10. This means the Canon EOS R5 can capture images more quickly, allowing for better action shots and faster response times. The EOS R5 also has a more advanced DIGIC X processor, which contributes to improved image quality, faster processing, and better performance.

On the other hand, the Sony a7R III has a higher DXOMARK score for its sensor, scoring 100 compared to the Canon EOS R5’s 95. This means the Sony a7R III’s sensor is capable of capturing higher quality images in terms of dynamic range, color depth, and low-light performance. Additionally, both cameras have different lens mounts, with the Canon EOS R5 using the Canon RF mount and the Sony a7R III using the Sony FE mount. This difference may be a deciding factor for those who already own lenses compatible with one of the mounts.

Considering the Canon EOS R5’s faster shooting speed and advanced processor, it is the superior camera in terms of optics. However, the Sony a7R III’s higher DXOMARK score and different lens mount might make it a more suitable choice for some photographers, depending on their needs and existing equipment.

The Sony a7R III, while falling short in comparison to the Canon EOS R5, still offers a respectable 4K video resolution and a maximum video frame rate of 30fps. Although it lacks built-in time-lapse functionality, it can still capture time-lapse videos with external equipment. Despite its lower score, the Sony a7R III remains a solid option for those who do not require the advanced video features of the Canon EOS R5.

Given the significant difference in video capabilities, the Canon EOS R5 emerges as the clear winner in this comparison. Its superior video resolution, frame rate, and built-in time-lapse functionality make it an ideal choice for filmmakers and content creators seeking top-of-the-line video performance. The Sony a7R III, while not as impressive in this aspect, remains a viable option for those with less demanding video requirements.

The Canon EOS R5 comes out on top with a feature score of 87/100, while the Sony a7R III trails slightly behind with a score of 83/100. Both cameras share several key features, such as touchscreen capability, flip screens, and a lack of built-in GPS. Additionally, both cameras come equipped with WIFI and Bluetooth connectivity.

The Canon EOS R5 outperforms the Sony a7R III in terms of screen size and resolution. The R5 has a larger screen at 3.2 inches compared to the a7R III’s 3-inch screen. Furthermore, the R5 boasts a higher screen resolution of 2,100,000 dots, while the a7R III has a resolution of 1,440,000 dots. These differences contribute to the R5’s superior display and overall user experience.

Though the Sony a7R III does not surpass the Canon EOS R5 in any particular feature, it is important to note that it is still a high-quality camera. With a feature score of 83/100, the a7R III showcases a competitive and comparable set of features to the R5, making it a viable option for photographers who may prefer the Sony brand or have existing Sony equipment.

Considering the differences between the Canon EOS R5 and the Sony a7R III, the R5 takes the lead due to its larger screen size and higher resolution. However, the Sony a7R III remains a strong contender in the market, offering a solid set of features that closely rival those of the R5. Ultimately, the choice between these two cameras will depend on personal preferences and brand loyalty.

The Canon EOS R5 wins the storage and battery comparison with a score of 68/100, while the Sony a7R III scores 65/100. Both cameras have two memory card slots and accept SD/SDHC/SDXC (UHS-II compatible) cards. The EOS R5, however, also accepts CFexpress cards, providing faster transfer speeds and larger storage capacities.

The Sony a7R III has the advantage in battery life, offering 650 shots per charge, compared to the EOS R5’s 320 shots. However, the Canon EOS R5 uses the LP-E6NH battery type and offers USB charging, which the a7R III lacks with its NP-FZ100 battery.

Considering these factors, the Canon EOS R5 has superior storage capabilities due to its CFexpress compatibility, but the Sony a7R III has a longer battery life. USB charging in the EOS R5 provides added convenience for users. Despite the slight scoring difference, both cameras offer reliable storage and battery performance suitable for various photography needs.
