Canon 6D Mark II vs G9X
The Canon EOS 6D Mark II and the Canon PowerShot G9 X are two digital cameras that were officially introduced, respectively, in June 2017 and October 2015. The 6D Mark II is a DSLR, while the G9X is a fixed lens compact. The cameras are based on a full frame (6D Mark II) and an one-inch (G9X) sensor. The 6D Mark II has a resolution of 26 megapixels, whereas the G9X provides 20 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 6D Mark II and the Canon PowerShot G9 X? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
An illustration of the physical size and weight of the Canon 6D Mark II and the Canon G9 X 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.
The G9X can be obtained in two different colors (black, silver), while the 6D Mark II is only available in black.
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 (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 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 built 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 compare the optics available 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 can take 220 images on a single charge of its NB-13L power pack. The power pack in the G9X can be charged via the USB port, which can be very convenient when travelling.

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 was launched at a lower price than the 6D Mark II, despite having a lens built 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.
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 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.
In terms of chip-set technology, the 6D Mark II uses a more advanced image processing engine (DIGIC 7) than the G9X (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.
With 26MP, the 6D Mark II offers a higher resolution than the G9X (20MP), but the 6D Mark II nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 2.41μm for the G9X) due to its larger sensor. Moreover, the 6D Mark II is a somewhat more recent model (by 1 year and 8 months) than the G9X, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 6D Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 6D Mark II for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 cm. The corresponding values for the Canon G9 X are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.
The 6D Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 6D Mark II has a native sensitivity range from ISO 100 to ISO 40000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon PowerShot G9 X are ISO 125 to ISO 12800 (no boost).
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, with an overall score that is 22 points higher. This advantage is based on 2.9 bits higher color depth, 0.4 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).
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 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 along with similar information for a selection of comparators.

One feature that is present on the 6D 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 6D Mark II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the G9X does not have a selfie-screen.
The Canon 6D Mark II and the Canon G9 X both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the 6D Mark II and the G9X write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 6D Mark II and Canon PowerShot G9 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 6D Mark II has a hotshoe, while the G9X does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Travel and landscape photographers will find it useful that the 6D Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The 6D Mark II is a recent model that features in the current product line-up of Canon. In contrast, the G9X has been discontinued (but 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. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what is the bottom line? Which of the two cameras – the Canon 6D Mark II or the Canon G9 X – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

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 (19 : 8 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon 6D Mark II and the Canon G9 X place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.
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 shooting experience and imaging performance when actually working with the 6D Mark II or the G9X. 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 ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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.
