EOS-1D X Mark III vs. EOS-1D X Mark II Comparison

The beauty of perfection. Discover what makes the EOS-1D X Mark III the fastest, most powerful EOS we’ve ever built

The EOS-1D X Mark III is the professional camera best suited for wildlife and sports photographers who want to keep ahead of the competition. Check out why it could be time to upgrade


PIXELS (MEGAPIXELS)	20.2	20.1	A new 20.1 megapixels full frame CMOS sensor is a good balance of performance and resolution that allows for higher ISO performance. Additionally, for major sports and news agencies where speed of sending images is everything, this is the perfect resolution for transmitting images.
AF POINTS/ NO. OF CROSS TYPE AF POINTS	61/41	191/155	New AF system enables high focusing accuracy. The sensor also supports head detection so it recognises athletes in different situations – even if they are wearing goggles or a helmet.
IMAGE PROCESSOR	Dual DIGIC 6+	DIGIC X	The new single DIGIC X Image Processor allows for outstanding image processing speed and camera responsiveness offering 3x times the processing power.
ISO SENSITIVITY	100-51,200 (expandable to 50-409,600)	100-102,400 (expandable to 50- 819,200)	The standard ISO range has been increased, providing the flexibility to shoot under any conditions.
CONT. SHOOTING (OVF/LIVE VIEW)	14 fps/16 fps* no AF tracking	16/20 fps	Capture fleeting moments in a second with fast speeds.
VIDEO	4K video (60p), Full HD (120p)	5.5K RAW (60p), 4K DCI (60p), 4K UHD (60p), Full-HD (120p)	EOS-1D X Mark III is the first EOS-1 series model to support Movie Digital IS. This advanced camera offers 5.5K video that can be recorded internally.
CANON LOG	No	Yes	Shooting with Canon Log captures more detail with 10bit recording.
FOCUSING	Dual Pixel CMOS AF	Dual Pixel CMOS AF (with touchscreen and the new smart controller) + New Low Pass Gaussian Filter	Dual Pixel CMOS AF tracks continuously and consistently and is extremely accurate in acquisition and tracking. Additionally, the new low pass Gaussian filter enables the image to be sharper with less moiré by sampling light points over more pixels.
BATTERY LIFE	Approx. 1,210 shots (at 23 °C) or Approx. 1,020 (at 0 °C)	Approx. 2,850 shots (at 20 °C) or Approx. 2,360 shots (at 0°C)	Increased battery life lets you shoot for longer, allowing more opportunities to get the shot.
CONNECTIVITY	Gigabit Ethernet, external WFT-E8 & WFT-E6 wireless transmitter	Built-in Wi-Fi (and external WFT-E9 booster), Bluetooth, Gigabit Ethernet	The EOS-1D X Mark III is the first EOS 1 series camera to have built in Wi-Fi and Bluetooth.
MEMORY CARD	1 x CompactFlash Type I (UDMA 7 compatible) (Incompatible with Type II and Microdrive), 1x CFast 2.0™	2 x CFexpress Card Type B	CFexpress cards have significantly higher writing speeds, enabling you to shoot RAW movies internally, and offers unlimited shooting for RAW and JPEG at 20 shots/sec.
SHUTTER LIFE	400,000	500,000	Longer shutter life means the EOS-1D X Mark III will shoot more frames before it needs replacing.
FILE FORMATS	CR2 (RAW), JPEG	CR3 (RAW), JPEG, HEIF	HEIF enables images to be smaller than a JPEG without suffering from compressed artefacts. This format also supports larger bit depths.
GPS	Yes	Yes	Built-in GPS is compatible with global satellites and automatically adds geotag information including longitude, latitude and Coordinated Universal Time.
WEIGHT	1,530g	1,440g	A lighter body helps keep the overall weight of your kit low, making it easier to carry the camera around, especially for longer assignments.
