Canon 1D X Mark II versus Canon G9 X

The Canon EOS-1D X Mark II and the Canon PowerShot G9 X are two digital cameras that were announced, respectively, in February 2016 and October 2015. The 1DX Mark II is a DSLR, while the G9X is a fixed lens compact. The cameras are based on a full frame (1DX Mark II) and an one-inch (G9X) sensor. Both cameras offer a resolution of 20 megapixel. 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 Mark II vs Canon G9 X

The side-by-side display below illustrates the physical size and weight of the Canon 1D X Mark II and the Canon G9 X. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 1DX Mark II – represents the basis or 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 is considerably smaller (79 percent) than the Canon 1D X Mark II. It is worth mentioning in this context that the 1DX Mark II is splash and dust resistant, while the G9X does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X has a lens build in, whereas the 1DX Mark II 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 Mark II and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 1DX Mark II gets 1210 shots out of its LP-E19 battery, while the G9X can take 220 images on a single charge of its NB-13L power pack. As can be seen in the images above, the 1DX Mark II has a battery grip build in. This facilitates image-taking in portrait orientation and contributes to its long-lasting power supply.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Any camera purchase will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G9X was launched at a lower price than the 1DX Mark II, 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 Mark II vs Canon G9 X

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 1D X Mark II features a full frame sensor and the Canon G9 X an one-inch sensor. The sensor area in the G9X 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 Mark II and Canon G9 X sensor measures

Even though the 1DX Mark II has a larger sensor, both cameras offer the same resolution of 20 megapixel. This implies that the 1DX Mark II has a lower pixel density and larger individual pixels (with a pixel pitch of 6.57μm versus 2.41μm for the G9X), which gives it a potential advantage in terms of light gathering capacity. In addition, the 1DX Mark II is a somewhat more recent model (by 3 months) than the G9X, and its sensor might have benefitted from technological advances during this time.

1DX Mark II versus G9X MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the 1DX Mark II provides substantially higher image quality than the G9X, with an overall score that is 25 points higher. This advantage is based on 2.6 bits higher color depth, 1.2 EV in additional dynamic range, and 2.7 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 1DX Mark II provides a higher video resolution than the G9X. It can shoot video footage at 4K/60p, while the G9X is limited to 1080/60p.

 

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

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 1DX Mark II has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G9X 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 Mark II and Canon G9 X along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

One feature that is present on the 1DX Mark II, but is missing on the G9X is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The 1DX Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the G9X has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the G9X was succeeded by the Canon G9 X Mark II.

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

So how do things add up? Which of the two cameras – the Canon 1D X Mark II or the Canon G9 X – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Canon EOS-1D X Mark II:

  • Better image quality: Scores substantially higher (25 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (2.6 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (1.2 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (2.7 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/60p vs 1080/60p).
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Easier setting verification: Features 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.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (16 vs 6 flaps/sec) to capture the decisive moment.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (1210 versus 220) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More modern: Is somewhat more recent (announced 3 months after the G9X).


Arguments in favor of the Canon PowerShot G9 X:

  • Ready to shoot: Comes with an integrated lens, while the 1DX Mark II 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 Mark II).
  • 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 heavily discounted: Has been on the market for longer (launched in October 2015).

If the count of relative strengths (bullet points above) is taken as a measure, the 1DX Mark II is the clear winner of the match-up (16 : 7 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 Mark II 16:07 G9X

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 Mark II or the G9X 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 expert reviews are important.

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
