Canon 6D Mark II versus Canon G9 X Mark II

The Canon EOS 6D Mark II and the Canon PowerShot G9 X Mark II are two digital cameras that were officially introduced, respectively, in June 2017 and January 2017. The 6D Mark II is a DSLR, while the G9X Mark II is a fixed lens compact. The cameras are based on a full frame (6D Mark II) and an one-inch (G9X Mark II) sensor. The 6D Mark II has a resolution of 26 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 6D Mark II vs Canon G9 X Mark II

An illustration of the physical size and weight of the Canon 6D Mark II and the Canon G9 X Mark II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button 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 6D 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 Mark II is considerably smaller (64 percent) than the Canon 6D Mark II. It is worth mentioning in this context that the 6D Mark II 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 6D 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 6D Mark II and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 6D Mark II gets 1200 shots out of its LP-E6N battery, while the G9X Mark II can take 235 images on a single charge of its NB-13L power pack.

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

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G9X Mark II was launched at a lower price than the 6D 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 6D Mark II vs Canon G9 X Mark II

The size of the sensor inside a digital camera is one of the key determinants 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. 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.

Of the two cameras under consideration, the Canon 6D Mark II 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 6D Mark II and Canon G9 X Mark II sensor measures

With 26MP, the 6D Mark II offers a higher resolution than the G9X Mark II (20MP), but the 6D Mark II nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 2.41μm for the G9X Mark II) due to its larger sensor. Moreover, the 6D Mark II is a somewhat more recent model (by 5 months) than the G9X Mark II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The 6D Mark II has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

6D Mark II versus G9X Mark II MP

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 6D Mark II provides substantially higher image quality than the G9X Mark II, with an overall score that is 20 points higher. This advantage is based on 2.5 bits higher color depth, 0.6 EV of lower dynamic range, and 2.5 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Canon 6D Mark II vs Canon G9 X Mark II

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 6D Mark II 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 6D Mark II and Canon G9 X Mark II along with similar information for a selection of comparators.

  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • 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.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (1200 versus 235) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More modern: Is somewhat more recent (announced 5 months after the G9X Mark II).


Arguments in favor of the Canon PowerShot G9 X Mark II:

  • More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
  • Faster burst: Shoots at higher frequency (8.2 vs 6.5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the 6D Mark II requires a separate lens.
  • More compact: Is smaller (98x58mm vs 144x111mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the 6D Mark II).
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • 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 January 2017).

If the count of relative strengths (bullet points above) is taken as a measure, the 6D Mark II is the clear winner of the match-up (15 : 9 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

6D Mark II 15:09 G9X Mark II

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 6D Mark II or the G9X Mark II. 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 where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, 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 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.
