The Canon 5D Mark IV does not output 4k from its HDMI port, which was a big complaint among users when it was released in 2016 (it does record 4k internally, however). For my workflow, this was not an issue as I’m almost always shooting and editing in 1080p. No camera in recent memory has received or, dare we say it, deserved this amount of hype. The Canon EOS R5 is a powerhouse performer in every possible respect; its 8K video outclasses many of the best cinema cameras, its shooting speed puts it on par with the best cameras for sport, and its 45MP sensor outmuscles all but a few of the best mirrorless cameras, and its 8-stop in-body image 12-21-2017 06:27 PM. There are no official specifications that mention a 1.7x crop factor when shooting 4K with the EOS 5D Mark IV. I see where some web sites mentioned that but nothing from Canon which means I cannot substantiate whats on a third party site. Even if [ : Dual Pixel RAW ] is set to [Enable], you cannot record [ ] or [ ] images appended with the Dual Pixel data (only possible with images). If [ : Record func+card/folder sel. ] is set to [Rec. separately] and the image-recording quality is set to [ ] for one card and [ ] or [ ] for the other, Dual Pixel RAW shooting cannot be performed. It even includes Bluetooth, focus bracketing and illuminated buttons while the Canon 5D Mark IV does not. Of course, there is one important factor to keep in mind—the price. The Nikon D850 is the more expensive of the two at $3,296.95 MSRP while the Canon 5D Mark IV is about $200 cheaper at $3,099.00 MSRP for the body only. The Canon EOS 5D Mark IV is one heck of a nice upgrade from the Canon 5D MK III. It has an improved sensor of 30.4 megapixel CMOS sensor with a Digic 6+ processor and 4K video at 23.98, 24, 25 and 30 fps. The Verdict. 9. out of 10. Canon EOS R5. The Canon EOS R5 remains the best Canon camera for most uses, and one of the best stills cameras full stop. Two years after release, it's proved to be everything the professional workhorse we'd hoped for thanks to superb autofocus, super rapid burst shooting and the added bonus of up to 8K video. On the 5D Mark IV the 1.75x crop when shooting 4K in the common 16:9 aspect ratio gives you a 50mm field of view from a wide angle 28mm, which is a bit shit. Where is the sweet spot? Obviously the Sony A7S II leads the field on sensor size in 4K but surprisingly the crop sensor mirrorless cameras tick quite a few boxes even for those looking And I shoot sports (indoor hockey) from Canon with 70-200/2.8, Nikon 70-200/2.8 and from mirrorless small camera with 70-200/2.8 equivalent. Without any modifications, I posted pictures from the same shooting to different people = none was able to determine which camera is where (Nikon setup was 8K, Canon about 5K and mirrorless about 2.5K). Camera: Canon 5D IV. Hello, I have recently started recording in 4K (4096x2160 - 29.97 fps - MOV) I noticed that I can't import it to my PC when the videos get longer, 20 sec videos work fine. But anything above that it just won't show up when I try to import it to Windows. They run fine on my camera, I can replay them etc. KeEYem5.
