The Canon EOS 6D Mark II takes the lead with a score of 71/100, while the Canon EOS 5D Mark III trails behind with a score of 65/100. Both cameras are DSLRs and were launched at different times – the 5D Mark III in 2012 and the 6D Mark II in 2017. They share similarities in size, with the 6D Mark II being slightly smaller and significantly lighter, weighing only 1.00lbs compared to the 5D Mark III at 2.09lbs.

The 6D Mark II excels with its more recent release and lower launch price of $2000, compared to the 5D Mark III’s $3499. The 5D Mark III, however, has a higher weight, which can be a preference for some photographers looking for a more substantial feel. Ultimately, the 6D Mark II offers better value and a more compact design, while the 5D Mark III may appeal to those who prefer a heavier camera.

Canon EOS 5D Mark III vs EOS 6D Mark II Overview and Optics

The Canon EOS 6D Mark II edges out the Canon EOS 5D Mark III in the optics department with a score of 69/100 compared to 67/100. Both cameras share several specifications, including a full-frame CMOS sensor, Canon EF lens mount, and a lack of image stabilization.

The 6D Mark II’s higher score is due to its superior megapixel count and shooting speed. With 26.2 megapixels, it captures more detail than the 5D Mark III, which has 22.3 megapixels. Additionally, the 6D Mark II has a faster shooting speed at 6.5 frames per second compared to the 5D Mark III’s 6 frames per second. The 6D Mark II also boasts a better processor, the DIGIC 7, which contributes to its improved image quality and speed.

The 5D Mark III, however, has its own advantages. It features a DIGIC 5+ processor, which, while not as advanced as the DIGIC 7, still delivers reliable performance. The 5D Mark III’s DXOMARK sensor score of 81 is only slightly lower than the 6D Mark II’s 85, indicating that the difference in image quality between the two cameras may not be drastic.

Taking these factors into account, the Canon EOS 6D Mark II is the better camera in terms of optics. Its higher megapixel count, faster shooting speed, and more advanced processor give it an edge over the Canon EOS 5D Mark III. While the 5D Mark III remains a competent camera, the 6D Mark II’s improvements make it the superior choice for those prioritizing optical performance.

Canon EOS 5D Mark III vs EOS 6D Mark II Video Performance

The Canon EOS 6D Mark II takes the lead in video capabilities with a score of 57/100, while the Canon EOS 5D Mark III trails closely behind with a score of 56/100. Both cameras feature Full HD video resolution with maximum dimensions of 1920 x 1080. However, the similarities in their video specifications end here.

The Canon EOS 5D Mark III outperforms the 6D Mark II in terms of maximum video frame rate, offering 60fps compared to the 6D Mark II’s 30fps. This higher frame rate allows for smoother video playback and is especially beneficial when capturing fast-moving subjects or creating slow-motion footage.

On the other hand, the Canon EOS 6D Mark II boasts a built-in time-lapse functionality, which the 5D Mark III lacks. This feature enables users to easily capture time-lapse videos without the need for additional equipment or software, making it a more convenient option for those interested in this type of videography.

While the Canon EOS 5D Mark III offers a higher video frame rate, the Canon EOS 6D Mark II’s built-in time-lapse functionality makes it the winner in terms of video capabilities. The 6D Mark II’s additional feature provides an advantage for users looking to create time-lapse videos without extra hassle. However, for those prioritizing smooth playback and slow-motion footage, the 5D Mark III’s higher frame rate might be more appealing. Ultimately, the choice between these two cameras for video capabilities will depend on the user’s specific needs and preferences.
