Who should opt for the Canon EOS-1D X Mark II?
If you are a photographer primarily interested in capturing fast-action sports, the EOS-1D X Mark II’s blazingly fast 14 fps burst rate and huge 170 frames RAW buffer (in our tests, the buffer was actually only limited to the CFast memory card’s capacity) will help you capture the optimal moment(s) when the action is at its peak. And if your sporting event is held in inclement weather, the 1D X II’s extra weather sealing will certainly be appreciated.
If you’re primarily a studio photographer who doesn’t need more than roughly 20 MP of resolution, the 1D X II’s gigabit Ethernet port is a great asset for tethered shooting.
Those using their DSLR to capture video will appreciate the 1D X II’s 4K recording at 60 fps, although the larger body may prove cumbersome in some setups. A benefit for some filmmakers (and a drawback for others) is the 1D X II’s approximate 1.3x focal length crop factor utilized in 4K video recording allowing for wider angles of view to be captured at the same focal length compared to the 5D Mark IV featuring a 1.74x crop factor.
Nearly every photographer can benefit from the 1D X II’s higher resolution metering sensor, and AF point-linked Spot metering feature (very helpful) is only available on 1-series bodies. The ability to change focus screens is another benefit of the 1D X II that could prove important for some photographers.
Who should opt for the Canon EOS 5D Mark IV?
If you need more resolution than the EOS-1D X Mark II offers, require built-in Wi-Fi/NFC, prefer a smaller and lighter camera body and/or your budget simply does not extend to the level of a 1-series body, the EOS 5D Mark IV will likely prove to be a great choice.
Sharing many important primary features with the EOS-1D X Mark II (with reasonable compromises on others), the EOS 5D Mark IV is the second-most versatile camera Canon has ever produced (the 1D X II being the most versatile). Considering that the 5D Mark IV costs over 40% less than the 1D X II (USA MSRP), those compromises will seem very reasonable for a great number of pro, semi-pro, enthusiast and hobbyist photographers alike.
