The greater resolution metering sensor in the 1D X II is beneficial to almost every photographer, and the AF point-linked Spot metering function is only accessible on 1-series models. An additional advantage of the 1D X II that may be relevant to certain photographers is the option to switch between different focus displays. The list of launch pricing provides an indicator of the market sector that the camera maker has been aiming its products towards.  
The device contains a standard memory slot, which allows you to expand the built-in internal storage capacity with inexpensive memory modules, or to quickly recover data from a memory card, such as images. When you use autofocus tracking, after you have chosen your subject and pressed the shutter release halfway down, the autofocus will follow your subject as it moves. The greater the number of focus points, the greater the degree of freedom in selecting whatever area of the picture to concentrate on.  
  
In addition, they're both sensitive down to -3EV, which means that you can use either camera to focus automatically in near darkness. Due to the fact that phase-detection autofocus is substantially quicker than contrast detection autofocus, clearer photographs may be captured. A hot shoe may be used to connect an external flash, as well as light meters, viewfinders, rangefinders, and other accessories to a camera or other device.  
When compared to contrast detection autofocus systems, phase detection autofocus systems are far quicker. When filming scenarios with a lot of quick motion, the movies remain crisp and clear. Although it may be possible to choose from a variety of different frame rates, the resulting recordings are often of inferior resolution. The EOS 5D Mark IV is the second-most versatile camera Canon has ever made, and it shares several significant core characteristics with the EOS-1D X Mark II.  
  
Excellent picture quality from RAW files; increased dynamic range; excellent high ISO performance; fast 7fps burst rate with an infinite JPEG buffer; and a small footprint. 4K footage of exceptional quality for the cinema; Wi-Fi is pre-installed. The Dual Pixel CMOS AF system performs well. A camera sensor's color depth, dynamic range, and low-light sensitivity are all evaluated by DxoMark, which also provides an overall score for the sensor. The 5D MIV has earned 91 points, which is three points greater than the 1D X MII, which is the other camera in this comparison. Also bear in mind that when comparing two interchangeable camera bodies, the weight of the bodies is not the only thing to consider; you must also consider the weight of the lenses that will be used with the cameras. The fact that both the Canon 5D MIV and the Canon 1D X II use the identical Canon EF lens mount and Full frame sized sensors means that lenses will not be a distinction in terms of overall system size.  
Canon EOS 5D Mark IV is a DSLR camera in the Advanced class, whereas Canon EOS-1D X Mark II is a DSLR camera in the Professional class.  
This makes it easier to take pictures in portrait orientation and provides it more battery life, both of which are beneficial. Canon offers the BG-E20 vertical grip as an optional attachment for the 5D Mark IV in order to give a comparable level of capability for the camera. Once again, I shared a mm f/2.8L IS II USM lens between two camera bodies in the studio while maintaining the same position for the subject, who was photographed under similar lighting conditions all of the time. Despite the fact that I shot freehand, as you can see from the picture, the model's head and hair served as a direction for where she should be placed inside the frame. The auto image style and white balance were employed in this scenario just to assess how they would behave in an informal test setting.  
The table below summarizes the connection of the Canon EOS-1D X Mark II and Canon EOS 5D Mark IV, in particular, the interfaces the cameras offer for accessory control and data transmission. The cameras are listed in descending order of compatibility with the relevant devices. The Canon EOS-1D X Mark II and the Canon EOS 5D Mark IV are two professional cameras that were introduced to the public, respectively, in February 2016 and August 2016. Both cameras are based on the Canon EOS-1D X Mark II sensor. Cameras with higher resolutions are more expensive; the 1DX Mark II has 20 megapixels, whilst the 5D Mark IV has 30.1 megapixels. Because none of these bodies are equipped with sensor-based image stabilization, you will need to purchase lenses that provide optical stabilization.  
  
Unfortunately, since Wi-Fi is not incorporated into the camera, it is only available as an optional feature. As a result, the camera only includes an in-body GPS receiver. It is possible to construct a short film by putting together a sequence of images shot from the same location over a lengthy period of time. A terrific method to catch things like the setting sun or clouds moving across the sky is using a long exposure photography technique.  
The size of the sensor included inside a digital camera is one of the most important factors influencing picture quality. The same technical generation of sensor will have smaller pixels, but a big sensor will have larger individual pixel-units that will provide superior low-light performance, a broader dynamic range, and a richer color depth than smaller pixels in a sensor of the same technological generation. Furthermore, when employing narrow depth-of-field to separate a subject from its backdrop, a big sensor camera will provide the photographer with extra creative alternatives. Larger sensors, on the other hand, are more costly and result in larger and heavier cameras and lenses, which are less portable.
