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.
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.
