Inspired by Andy Day's post about his Canon 6D, I though I would add my thoughts on the Canon 5D Mark II, especially as we have had several upgrades since then, like the 5D Mark IV that I have Canon 5D Mark IV vs Canon 5D Mark III at Base ISO. Canon 5D Mark IV at ISO 100. Canon 6D Mark II. Canon 77D. Canon 7D Mark II. Canon 90D. Canon G5X Mark II. Canon G7X Mark II. Canon G9X Mark II. At +1 EV, the 6D II appears similar to the 5D Mark IV. At +2 EV, we see images from both the 6D II and 5D IV beginning to lose some color detail in the brightest portions of the image. The two cameras appear similar at this point and with the exception of the bottom-most yellow block, they are about the same at +3 EV. Has phase-detection autofocus for videos. Canon EOS 6D Mark II. Sony a7R IV. A phase-detection autofocus system is faster than a contrast detection autofocus system. Even when recording scenes with a lot of fast movements, the videos are sharp and clear. has continuous autofocus when recording movies. Canon EOS 6D Mark II. 他のフレームレートを選択することも可能だと思われますが、それらの録画は、通常低解像度です。. 位相差検出オートフォーカスにより動画を録画するとき、高速なビデオオートフォーカスを行います. Canon EOS 5D Mark IV. Canon EOS 6D Mark II. 位相差検出オート Canon EOS 5D Mark IV: 7fps. Canon EOS 6D Mark II: 6.5fps. The 7fps continuous shooting mode of the EOS 5D Mark IV has a slight but negligible advantage over the EOS 6D Mark II's 6.5fps rate, but its in burst depth where the two differ more from each other. If they need dual card slots the 5D Mark IV is the better choice. Also the 5D Mark IV offers 4K video over 1080p video that the 6D Mark II offers. But I think OP would be better off with the 6D Mark II. -Demetrius. 40D, 5D IV, EF 16-35mm F/2.8L III, EF 24-70mm F/2.8L II, EF 28-135mm F/3.5-5.6 IS USM, EF 50 F/1.8 STM. 430EX III-RT & 600EX II-RT Canon EOS 6D Mark II is more versatile than Canon EOS 5D Mark III (90 a 82). The handling of Canon EOS 6D Mark II (66) is more effective than that of Canon EOS 5D Mark III (56). But, as you may know, the technical performance is meaningless if applied to the wrong context. DAfP.
