The Good Excellent low-light capabilities. Vertical grip configuration is comfortable and effective. Quick, effective autofocus. Incredible burst shooting speeds. Weatherproof body.

The Bad Two hands required to change shooting mode. Wi-Fi connectivity requires a separate module. No USB 3.0 interface. No headphone monitoring.

The Bottom Line Designed for sports and demanding professional photographers, the Canon EOS 1D X is an excellent SLR which will not disappoint.

9.3 Overall

The 1D X has taken its time to reach production, first being announced in October 2011. As cameras finally hit store shelves for professionals around the world, much of the fanfare has been subdued by releases like the Nikon D4, which hit the market first.

Canon has chosen to replace the full-frame 1Ds Mark III and APS-H 1D Mark IV with a single camera, the 18-megapixel full-frame 1D X, which uses dial Digic V processors.

Make no mistake, this camera is an extreme photographic machine for professionals. If the ridiculous continuous frame rate doesn't give that away, then the price tag certainly will.

Design and features

Befitting a camera of its class and stature, the 1D X is dust- and splash-proof, coming with a rugged fit and finish to ensure a robust user experience. It's made of magnesium alloy, which is sturdy and will stand up to the tough conditions a sports and professional SLR lives through, with weatherproofing to seal the deal.

The camera has two main grips, one for regular landscape shooting and the other, a close replica for portrait shooting. Grips ensure that the body sits firmly in the hand, with buttons and dials all within easy reach. Access to AF-ON, exposure lock and shutter buttons are available in both shooting configurations. Even though the 1D X is a beast of a camera, the ergonomic feel doesn't make it seem all that cumbersome.

The rear of the camera houses a 3.2-inch, 1.04-million dot LCD screen, which is bright and easy to see in daylight situations as it offers a 170-degree viewing angle. Like other Canon high-end models, a control wheel with a Set button at its centre gives access to menu options and shooting controls.

Dual CompactFlash slots are hidden under a locking door at the back. The slots offer four functionalities for shooting: single card recording; overflow control; separate recording of different sized images to each card; redundancy recording (or RAW and JPEG on either card).

The 1D X has a ridiculous native ISO range of 100-51,200, that promises a lot when it comes to low-light performance. Fortunately, the firmware update, which was released in October 2012, makes the AF points far more visible when shooting in dim situations. Without the firmware update, the points are black (rather than the regular glowing red).

Anyone familiar with the 5D Mark III will feel right at home on the 1D X, as the menu systems and options are pretty much the same. Dual joysticks provide a tactile, firm response when moved. One usability quirk is the fact that you have to use two hands to adjust shooting modes between PASM; one to press the mode button and the other to turn a dial. The viewfinder is big, bright and efficient, offering 100 per cent coverage.

Canon offers a top and rear LED panel for displaying and adjusting shooting options. Also, within the menus, Canon has provided an actuation (shutter) counter, so you don't need to take it for a service to get this figure.

The 1D X is compatible with a wireless transmitter and GPS unit, though unfortunately, we were not supplied with one for review. Also on the connectivity front, expect a 3.5mm microphone jack, HDMI, remote port and also an Ethernet jack. The 1D X does miss out on a headphone jack for monitoring audio during and after recording.


In this section, we'll discuss the use of the wired LAN functionality of the 1D X. Unfortunately, we were not supplied with a wireless adapter, so we cannot comment on its performance. However, functionality should be similar.

The 1D X gives you access to four main functions when connected via Ethernet: FTP transfer; download and tethering through EOS Utility; WFT Server for download and tethering through a web browser; and viewing images on a DLNA TV using the camera as a media server.

Like the Nikon D4, the Canon 1D X doesn't have a DHCP server built-in, so for automatic configuration that's plug-and-play, you will need to plug the camera into an intermediary device, such as a router with a DHCP server. Otherwise, you need to set a static IP address on both the camera and the computer manually.

Once the camera has been configured and can be seen by the computer, the EOS Utility can access the camera in a number of ways, to pull down images or to tether. The tethering option works exactly the same as when the camera is connected via USB, allowing access to exposure control, a preview image and fine-tuning autofocus. When we tested the tethering functionality using Live View, it was efficient and very quick, with only a very small amount of latency noticeable.

The 61-point AF system performs incredibly well in a range of shooting situations. All the focusing controls are found on a dedicated page in the camera's menu system and are similar to the options provided on the 5D Mark III. Users get the choice between six cases for AF situations, from a multi-purpose scenario, through to specific settings for fast-moving subjects. When it comes to tracking fast-moving subjects, like kids and skateboarders, the 1D X is in a class of its own.
