The Canon EOS 6D Mark II takes the lead with a score of 71/100, while the Canon EOS Rebel T8i / 850D trails behind at 59/100. Both cameras are DSLRs, with the 6D Mark II announced in 2017 and the T8i / 850D in 2020. They share similar dimensions, but the 6D Mark II is lighter at 453g compared to the T8i’s 515g.

The 6D Mark II’s higher score highlights its better performance and features, justifying its $2000 launch price. On the other hand, the T8i / 850D is a more budget-friendly option at $750, making it a suitable choice for those looking for a more affordable DSLR.

When considering these cameras, the Canon EOS 6D Mark II is the superior option due to its better performance and lighter weight. However, the Canon EOS Rebel T8i remains a viable alternative for those seeking a more budget-friendly DSLR.

Canon EOS 6D Mark II vs Rebel T8i Overview and Optics

The Canon EOS 6D Mark II emerges as the winner in the optics comparison with a score of 69/100, while the Canon EOS Rebel T8i / 850D trails behind with a score of 57/100. Both cameras share some common specifications, such as a CMOS sensor, no image stabilization, and compatibility with Canon EF lens mounts.

The 6D Mark II boasts a higher megapixel count of 26.2 compared to the 24 megapixels of the Rebel T8i / 850D, allowing for more detailed images. Additionally, the 6D Mark II has a full-frame sensor, which contributes to better low-light performance, dynamic range, and image quality compared to the Rebel T8i / 850D’s APS-C sensor. The 6D Mark II’s sensor also has a higher DXOMARK score of 85, indicating superior overall performance.

On the other hand, the Rebel T8i has a faster shooting speed of 7.5 frames per second, compared to the 6D Mark II’s 6.5 frames per second. This advantage may be beneficial for capturing fast-moving subjects, such as sports or wildlife photography. Also, the Rebel T8i has a more advanced processor, the Digic 8, which could result in faster image processing and improved performance in certain aspects.

Considering these factors, the Canon EOS 6D Mark II is the better choice for photographers seeking superior image quality, low-light performance, and overall sensor performance. However, the Canon EOS Rebel T8i / 850D may still appeal to those who prioritize faster shooting speeds and an advanced processor, while still offering compatibility with the vast range of Canon EF lenses.

Canon EOS 6D Mark II vs Rebel T8i Video Performance

The Canon EOS Rebel T8i / 850D outperforms the Canon EOS 6D Mark II in video capabilities with a score of 83/100 compared to the 6D Mark II’s 57/100. Both cameras share common features such as built-in time-lapse functionality, providing users with creative options for capturing dynamic scenes.

The Rebel T8i boasts superior specifications, most notably its 4K video resolution and maximum video dimensions of 3840 x 2160. This camera also offers a higher maximum video frame rate of 60fps, resulting in smoother footage. These factors contribute to the T8i’s higher score and make it a better choice for those prioritizing video quality.

On the other hand, the 6D Mark II offers Full HD video resolution with maximum video dimensions of 1920 x 1080 and a maximum video frame rate of 30fps. While these specs are inferior to the T8i / 850D, they still provide decent video quality for casual users or those with less demanding video needs.

In comparing these two cameras, it is clear that the Rebel T8i / 850D delivers superior video performance with its 4K resolution and higher frame rate. This camera is the better choice for videographers and enthusiasts seeking the best possible video quality.

Ultimately, the choice between these two cameras depends on the user’s specific video requirements and preferences.

Canon EOS 6D Mark II vs Rebel T8i Features and Benefits

The Canon EOS 6D Mark II wins the features comparison with a score of 83/100, while the Canon EOS Rebel T8i / 850D scores 70/100. Both cameras share several specifications, such as a 3-inch screen size, 1,040,000-dot screen resolution, touchscreen capabilities, flip screen, WiFi, and Bluetooth connectivity.

The 6D Mark II outperforms the Rebel T8i mainly due to its GPS feature, which the latter lacks. This GPS functionality allows photographers to geotag their images, making it easier to organize and locate photos based on location data. This feature is particularly useful for travel and landscape photographers who want to keep track of where their shots were taken.

On the other hand, the Rebel T8i / 850D does not have any clear advantages over the 6D Mark II in terms of features. Both cameras are evenly matched in all other aspects, as mentioned earlier.

Taking all points into consideration, the Canon EOS 6D Mark II is the superior choice when it comes to features, mainly because of its GPS capabilities. This makes it a more versatile option for photographers who require location data for their work. The Canon EOS Rebel T8i, while lacking GPS, still offers a solid set of features that make it a decent choice for those who do not need geotagging capabilities.

Canon EOS 6D Mark II vs EOS Rebel T8i / 850D Storage and Battery

The Canon EOS 6D Mark II outperforms the Canon EOS Rebel T8i/850D in storage and battery with a score of 45/100 compared to 35/100. Both cameras share common specifications, such as one memory card slot and compatibility with SD, SDHC, and SDXC (UHS-I) cards. Neither camera supports USB charging.

The 6D Mark II excels due to its longer battery life of 1200 shots, using the LP-E6N battery type. This advantage allows photographers to capture more images before needing a battery replacement. Meanwhile, the Rebel T8i/850D’s battery life is limited to 800 shots, utilizing the LP-E17 battery type.

In this comparison, the 6D Mark II emerges as the superior choice for storage and battery capabilities.
