The only way Canon will give you full frame 4K from the 5D Mark IV is if they have a pixel binning mode like Sony does on the A7R II. But as we saw from that camera, the image quality of 4K when pixel binning is used takes quite a drastic hit, with moire & aliasing as well as 2-3 stops worse low light performance. Weight: 5D Mark IV is 115 g lighter than D850. The 5D Mark IV weighs 1.76 lb / 800 g, while Nikon D850 offers 2.01 lb / 915 g. 4K Video: The 5D Mark IV can record in UHD 4K (3840 x 2160) at 30 FPS, while D850 can record DCI 4K (4096 x 2160) at 30 FPS. GPS: The 5D Mark IV comes with GPS, and D850 doesn’t. A truly versatile camera, EOS 5D Mark IV delivers DCI 4K shooting at up to 30 fps and the ability to extract 8.8MP JPEG images from 4K videos. Expanded auto focus 61-point (41 cross-type) AF covers an expanded sensor area and delivers focus at EV-3 in viewfinder shooting mode, or EV-4 in Live View mode. Along with the ability to capture full HD video clips at 1920 x 1080 resolution, Canon’s EOS 5D Mark II Digital SLR camera features a 21.1-megapixel full frame 24 x 36mm CMOS sensor, DIGIC 4 imaging processor and significantly lower noise, with an expanded sensitivity range from ISO 50 to ISO 25,600. Canon offers ‘uncropped’ 4K recording in a few cameras, including the EOS 90D and EOS M6 Mark II. Here, the full width of the image sensor is used to shoot an image, with the height of the image being cropped to give the correct aspect ratio for video playback. The camera then processes the image to reduce it to the correct 4K resolution. For the first time in an EOS 5D series DSLR camera, the EOS 5D Mark IV features built-in Wi-Fi® 1 and Near-Field Communication (NFC)™ 1 providing for the easy transfer of images and MP4 movies to compatible mobile devices, as well remote shooting when using the Canon Camera Connect App 2. The EOS 5D Mark IV also includes a built-in GPS 3 The EOS 6D Mark II is noticeably more compact than the EOS 5D Mark IV. The Canon EOS 6D Mark II has a revised AF system that’s considerably more advanced than the 11-point AF system with one cross-type point on the original EOS 6D. This latest model inherits the 45-point all-cross-type AF system from the EOS 80D. To keep differentiation between platforms, it's understandable not to bring that over to the 5D. The internal processing and record speeds, especially for 4k, aren't what the camera was designed to do. But to not bring H.265—a format available from Samsung on the NX-1 since 2014—into the Mark IV is a big missed opportunity. Most tests see .
