Canon 1D X versus Canon 70D
The Canon EOS-1D X and the Canon EOS 70D are two digital cameras that were announced, respectively, in October 2011 and July 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1DX) and an APS-C (70D) sensor. The 1DX has a resolution of 17.9 megapixel, whereas the 70D provides 20 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.
Body comparison: Canon 1D X vs Canon 70D
The physical size and weight of the Canon 1D X and the Canon 70D are illustrated in the side-by-side display below. Three successive views from the front, the top, and the rear 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 side – the 1DX – represents the basis for the calculations across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 70D is considerably smaller (46 percent) than the Canon 1D X. Moreover, the 70D is substantially lighter (51 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. A larger imaging sensor (as in the 1DX) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (70D). You can find a comprehensive 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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 70D was launched at a markedly lower price (by 82 percent) than the 1DX, which puts it into a different market segment. 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: Canon 1D X vs Canon 70D
The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 1D X features a full frame sensor and the Canon 70D an APS-C sensor. The sensor area in the 70D is 61 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the 70D offers a higher resolution of 20 megapixel, compared with 17.9 MP of the 1DX. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.11μm versus 6.95μm for the 1DX). However, it should be noted that the 70D is a somewhat more recent model (by 1 year and 8 months) than the 1DX, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the 1DX provides substantially higher image quality than the 70D, with an overall score that is 14 points higher. This advantage is based on 1.3 bits higher color depth, 0.2 EV in additional dynamic range, and 1.6 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).
Feature comparison: Canon 1D X vs Canon 70D
Beyond body and sensor, cameras can and do differ across a range of features. The 1DX and the 70D 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 70D in connection with corresponding information for a sample of similar cameras.

Review summary: Canon 1D X vs Canon 70D
So what is the bottom line? Is there a clear favorite between the Canon 1D X and the Canon 70D? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS-1D X:
- Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.3 bits more color depth).
- Better low-light sensitivity: Requires less light for good images (1.6 stops ISO advantage).
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- Faster burst: Shoots at higher frequency (14 vs 7 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (1120 versus 920) on a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in October 2011).
Reasons to prefer the Canon EOS 70D:
- More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More compact: Is smaller (139x104mm vs 158x168mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 796g or 51 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (82 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year and 8 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the 70D comes out slightly ahead of the 1DX (8 : 7 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 before making a camera decision.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 1DX or the 70D handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
