The reason why there is no argument about the 5dii vs the 6D regarding low light is that the 6D is a much newer camera, and more specifically built for travel and low-light performance, thus a much better choice. There is really no need for debate. LENR comes with every canon FF DSLR nowdays. The 6D records the settings used for canon EF lenses. supports Wi-Fi 5 (802.11ac) Canon EOS 5D Mark III. Panasonic Lumix S5. 802.11ac wireless works on the 5GHz frequency range. It offers higher transfer rates, improved reliability, and improved power consumption. It provides advantages for gaming and HD video streaming. The shutter life rating on the 6D’s shutter is 100K actuations. The 5D3 is rated for 150K. If you are the kind of user who is likely to hit the higher shutter count during your use of the camera, this is definitely a consideration. That being said, replacing a shutter is around $300; it’s not the price of a new camera. Honestly, I think that the 6D is a great camera for landscape photography. I think that the 5D4 will beat the 6D in dynamic range, and slightly edge the 6D in low light /noise performance. IMO the main advantage between the two, besides the 5D4 having higher MP, would be the AF points (61 vs 11) and cross-point AF (11 vs 1), and dual cards. We tested the Canon EOS R6 Mk II with a Canon RF 24-105 f4 lens from the manufacturer. Lensrentals also loaned us RF 15-35mm , RF 24-70mm f2.8 , and RF 70-200 f2.8 lenses.

The Canon EOS 6D and the Canon EOS 5D Mark III are both full-frame DSLRs, but while the 5D is designed as a rugged, professional camera, Canon really managed to cut down on size and weight for the 6D.

Overall audio features (like the headphone jack) not as great as the 5D mark III, but definitely better than the 5D mark II. That's why we always use the 5D mark III as a main camera, and close ups for lapel mic'd shots. And of course, the primary yet somehow not as practical reason of getting the 6D over the 5D mark II. The body has the same ergonomics and controls as the current 5D series but an older version of the menu system. It's still easy to navigate though. The 5D3 was a decent step up in image quality. The original 6D had better image quality than the 5D3, but the ergonomics, controls, and menu system aren't as good. Remarkable for its time, really—especially at higher ISOs. To me the R5 sensor is clearly a couple of generations beyond the 6D. For my use, the areas where the R5 annihilates the 6D are: 1) AF precision/accuracy. 2) AF tracking ability. 3) Low light AF sensitivity. 4) AF speed. 5) FPS. Honestly, I loved the 6D. 4fU6H.
