As it turns out, everything…
Both cameras sport the same full frame 18.1MP CMOS sensor, same Dual DIGIC 5+ processors, same 3.2″ LCD and everything else inside and out.
The only physical difference between the two cameras is the badge on the front and a trade-off between a flash sync port (1D X) and a headphone jack (1D C).
The video capture capabilities of the cameras as you find them on the shelf of retailers, however, are massively different. While both cameras capture video, the 1D C captures full 4K video using an 8-bit 4:2:2 high bit rate Motion JPEG compression scheme in addition to 1080p HD video at up to 60fps.
The Canon 1D X is crippled through Canon’s firmware to only have the ability to capture 1080p HD video at a max of 30fps (although you can capture 60fps if you bump the resolution down to 720p), which Canon caps at 29:59 minutes due to European tax restrictions.
Accordingly, that $13k price tag on the 1D C is for a few lines of code in the camera’s firmware that enable you to capture 4K resolution . . . and, of course, the headphone jack.
Is Canon being a little greedy on the 1D C pricing, or are there justifiable reasons for pricing the 4K camera nearly double the price of its 1080p-shooting twin?
