The 1D X features Canon’s full-frame 18.1MP CMOS sensor, which creates perfectly detailed, high-resolution images with unprecedented speed and clarity. It provides an extremely accurate 61-point autofocus system with 6 autofocus-point selection methods. In addition, it boasts a 100-51,200 ISO range, allowing for outstanding low-light performance.

This camera uses Dual DIGIC 5+ image processors that deliver speeds of up to 12 fps (RAW + JPEG) and 14 fps (JPEG). The Dual DIGIC 5+ is approximately 17x faster than its predecessor, and features new algorithms that promote greater noise reduction at higher ISOs.

On the video side, the 1D X records 1080p at 24/25/30 fps, as well as 720p at 50/60 fps. It has in-camera audio-level adjustment, timecode embedding, expanded clip length of 30 minutes, and two compression methods (ALL-I and IPB) for optimum quality.

The enlarged 3.2" 1,040K-dot TFT LCD greatly improves image review and live-view recording, while the 100% viewfinder with overlay allows for highly customizable viewing. The 1D X has two CF-slots, and while it comes with a higher-capacity LP-E4N battery, it’s still backwards-compatible with previous LP-E4 batteries.
