Canon 1D X versus Canon 1D X Mark II

The Canon EOS-1D X and the Canon EOS-1D X Mark II are two professional cameras that were revealed to the public, respectively, in October 2011 and February 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The 1DX has a resolution of 17.9 megapixel, whereas the 1DX Mark II provides 20 MP.

Body comparison

An illustration of the physical size and weight of the Canon 1D X and the Canon 1D X Mark II is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 1DX – represents 100 percent across all the size and weight measures).

In this particular case, the Canon 1D X and the Canon 1D X Mark II have exactly the same width and height, and, thus, have identically-sized bodies. However, the 1DX Mark II is slightly lighter (1 percent) than the 1DX. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Canon EF Lens Catalog.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 1DX Mark II was launched at a somewhat lower price (by 12 percent) than the 1DX, which makes it more attractive for photographers on a tight budget. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

While the two cameras under review share the same sensor size, the 1DX Mark II offers a higher resolution of 20 megapixel, compared with 17.9 MP of the 1DX. This megapixel advantage translates into a 6 percent gain in linear resolution. On the other hand, these sensor specs imply that the 1DX Mark II has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 6.57μm versus 6.95μm for the 1DX). However, it should be noted that the 1DX Mark II is much more recent (by 4 years and 3 months) than the 1DX, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the 1DX Mark II has a markedly higher DXO score than the 1DX (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.3 bits higher color depth, 1.7 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 1DX Mark II provides a better video resolution than the 1DX. It can shoot movie footage at 4K/60p, while the 1DX is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 1DX and the 1DX Mark II are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The table below summarizes some of the other core capabilities of the Canon 1D X and Canon 1D X Mark II in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The 1DX Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the 1DX has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the 1DX was succeeded by the Canon 1DX Mark II.

Summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 1D X and the Canon 1D X? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon EOS-1D X:

  • More heavily discounted: Has been available for much longer (launched in October 2011).

Reasons to prefer the Canon EOS-1D X Mark II:

  • More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
  • Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.7 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/60p vs 1080/30p).
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More affordable: Was released into a lower priced segment (12 percent cheaper at launch).
  • More modern: Reflects 4 years and 3 months of technical progress since the 1DX launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 1DX Mark II is the clear winner of the contest (8 : 1 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs.

1DX 01:08 1DX Mark II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 1DX and the 1DX Mark II in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
