For our latest camera comparison, we put the Canon 1DX up against the Sony A7 III. Let’s start with the dynamic range. It’s great on both cameras. The Sony A7 III has 15 Stops of DR. While the Canon 1DX has 13 Stops of DR. If you’re not experienced with color grading you might have a problem dealing with Sony Log footage. When it comes to obtaining Dynamic Range. The Sony has many options when it comes to Log Profiles for Color Grading. The 1DX Mark II doesn’t have flat color profiles for grading. But, if you hack the camera, you can access them.
When it comes to skin tones Sony Cameras aren’t usually praised. Yet, the Sony A7III has stepped up their game with new color science. Which makes the A7 III better than previous Sony Alpha Cameras. Yet, out of the box the Canon 1DX produces better skin tones in camera. One trick around this for Sony Alpha Shooters is to buy EOS PRO Color. I’ve found that with these color profiles, you lose a little dynamic range. Gaining a better highlight roll off and better skin tones.
Both cameras perform well when it comes to autofocus. The Canon 1DX working better when it comes to tracking in-video modes.
The Canon 1DX has an optical Viewfinder so that can be hard for video in bright situations. As you have to look at the screen to watch the video. The Sony A7 III screen is not the best quality. But I find the viewfinder awesome when shooting photography and Video.
The Sony A7III has more options when it comes to video codecs and more usability in post production. The A7III files are smaller and easier to edit or create proxy files.
The Canon 1DX has huge files when it comes to video, about 30 minutes of footage is around 128GB. So memory cards are going to fill up fast. This is due to the camera using motion JPEG. I know a lot of people like the quality it produces. But a lot of professionals think it’s a huge pain, especially the processing power it takes to edit these files.
