Canon 1D X versus Canon G9 X Mark II

The Canon EOS-1D X and the Canon PowerShot G9 X Mark II are two digital cameras that were announced, respectively, in October 2011 and January 2017. The 1DX is a DSLR, while the G9X Mark II is a fixed lens compact. The cameras are based on a full frame (1DX) and an one-inch (G9X Mark II) sensor. The 1DX has a resolution of 17.9 megapixel, whereas the G9X Mark II 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 G9 X Mark II

The side-by-side display below illustrates the physical size and weight of the Canon 1D X and the Canon G9 X Mark II. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions 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).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G9 X Mark II is considerably smaller (79 percent) than the Canon 1D X. It is worth mentioning in this context that the 1DX is splash and dust resistant, while the G9X Mark II does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X Mark II has a lens build in, whereas the 1DX is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the 1DX and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 1DX gets 1120 shots out of its LP-E4N battery, while the G9X Mark II can take 235 images on a single charge of its NB-13L power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 G9X Mark II was launched at a lower price than the 1DX, despite having a lens build in. 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 G9 X Mark II

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 G9 X Mark II an one-inch sensor. The sensor area in the G9X Mark II is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 1D X and Canon G9 X Mark II sensor measures

Despite having a smaller sensor, the G9X Mark II 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 2.41μm versus 6.95μm for the 1DX). However, it should be noted that the G9X Mark II is much more recent (by 5 years and 2 months) than the 1DX, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

1DX versus G9X Mark II MP

For most cameras, data on sensor performance has been reported by DXO Mark. 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 G9X Mark II, with an overall score that is 17 points higher. This advantage is based on 1.9 bits higher color depth, 0.7 EV of lower dynamic range, and 2.4 stops in additional low light sensitivity.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G9X Mark II provides a faster frame rate than the 1DX. It can shoot movie footage at 1080/60p, while the 1DX is limited to 1080/30p.

Feature comparison: Canon 1D X vs Canon G9 X Mark II

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 1DX has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G9X Mark II relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon 1D X and Canon G9 X Mark II along with similar information for a selection of comparators.

The G9X 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.

Review summary: Canon 1D X vs Canon G9 X Mark II

So what is the bottom line? Which of the two cameras – the Canon 1D X or the Canon G9 X Mark II – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS-1D X:

  • Better image quality: Scores substantially higher (17 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.9 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (2.4 stops ISO advantage).
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (14 vs 8.2 flaps/sec) to capture the decisive moment.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (1120 versus 235) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More heavily discounted: Has been available for much longer (launched in October 2011).

Advantages of the Canon PowerShot G9 X Mark II:

  • More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
  • More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Ready to shoot: Comes with an integrated lens, while the 1DX requires a separate lens.
  • More compact: Is smaller (98x58mm vs 158x168mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the 1DX).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Reflects 5 years and 2 months of technical progress since the 1DX launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 1DX comes out slightly ahead of the G9X Mark II (12 : 11 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

1DX 12:11 G9X Mark II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 1DX or the G9X Mark II handle or perform in practice. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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, please note that some of the review sites have changed their methodology and reporting over time.
