The 1D X Mark III builds upon its predecessor in many ways, especially when it comes to autofocus. It features an enhanced autofocus system with a new algorithm, subject tracking using Deep Learning Technology, and an optical viewfinder that uses a new autofocus sensor that has 28x the resolution of the 1D X Mark II.
Furthermore, shooters will be able to use 525 AF areas with the Dual Pixel CMOS AF system, covering the image sensor by 90 percent horizontally and 100 percent vertically. And these new AF and AE systems will be able to support much faster frame rates (for photographers, at least) when using either the optical viewfinder (up to about 16fps mechanical shutter) or Live View (up to about 20fps mechanical or electronic shutter).
This new shooter also boasts such intriguing features as an all-new Canon-developed CMOS sensor and DIGIC processor. Canon says the latter will provide higher ISOs, wider dynamic range, greater color representation, and 10-bit HEIF stills.
Unfortunately, there's one update that isn't included, that 1D Mark II users were hoping to see: Higher video resolution, preferably at higher frame rates. However, even though the 1D Mark III still only shoots 4K60P, it does make the jump from 8-bit to 10-bit 4:2:2 Canon Log internal recording.
- Enhanced AF and AE systems
- All-new Canon-developed CMOS sensor and DIGIC processor
- 4K60p with 10-bit 4:2:2 Canon Log internal recording
- Built-in Wi-Fi and Bluetooth low-energy connectivity and GPS technology
- Data transfer speeds twice that of 1D X Mark II (when using built-in Ethernet connection or wireless file transmitter)
- Dual CFexpress card slots
- Illuminated buttons
- Improved weather-sealing
- LP-E19 batteries
Despite getting a few tantalizing details about the 1DX Mark III, not much is known about other important features at this point, including specifics on the image sensor. We still do not know whether we're getting full-frame or something similar to the Mark II's 1.3x crop factor. Also unknown as of press time is ISO range, pricing, and more. It's still early in the development stage, so we'll keep you updated as more announcements come.
