Canon G9 X Mark II vs Nikon D780
The Canon PowerShot G9 X Mark II and the Nikon D780 are two digital cameras that were officially introduced, respectively, in January 2017 and January 2020. The G9X Mark II is a fixed lens compact, while the D780 is a DSLR. The cameras are based on an one-inch (G9X Mark II) and a full frame (D780) sensor. The Canon has a resolution of 20 megapixels, whereas the Nikon provides 24.3 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 PowerShot G9 X Mark II and the Nikon D780? 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.
The physical size and weight of the Canon G9 X Mark II and the Nikon D780 are illustrated in the side-by-side display below. 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 measures are rounded to the nearest millimeter.
The G9X Mark II can be obtained in two different colors (black, silver), while the D780 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 Nikon D780 is considerably larger (194 percent) than the Canon G9 X Mark II. It is noteworthy in this context that the D780 is splash and dust-proof, 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 built in, whereas the D780 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 D780 and their specifications in the Nikon Lens Catalog.
Concerning battery life, the G9X Mark II gets 235 shots out of its NB-13L battery, while the D780 can take 2260 images on a single charge of its EN-EL15b power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G9X Mark II was launched at a lower price than the D780, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 imaging sensor is a crucial determinant 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G9 X Mark II features an one-inch sensor and the Nikon D780 a full frame sensor. The sensor area in the D780 is 640 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors.
With 24.3MP, the D780 offers a higher resolution than the G9X Mark II (20MP), but the D780 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 2.41μm for the G9X Mark II) due to its larger sensor. Moreover, the D780 is a much more recent model (by 3 years) than the G9X Mark II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Nikon D780 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D780 for good quality output (200 dots per inch) amounts to 30.2 x 20.1 inches or 76.8 x 51.1 cm, for very good quality (250 dpi) 24.2 x 16.1 inches or 61.4 x 40.9 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inches or 51.2 x 34.1 cm. The corresponding values for the Canon G9 X Mark II 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 D780 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot G9 X Mark II has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Nikon D780 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, but the D780 provides a better video resolution than the G9X Mark II. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the D780 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 following table reports on some other key feature differences and similarities of the Canon G9 X Mark II, the Nikon D780, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The G9X Mark II has one, while the D780 does not. While the built-in flash of the G9X Mark II is not very powerful, it can at times be useful as a fill-in light.
The Canon G9 X Mark II and the Nikon D780 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 G9X Mark II and the D780 write their files to SDXC cards. The D780 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G9X Mark II only has one slot. The D780 supports UHS-II cards (on both slots), while the G9X Mark II can use UHS-I cards.
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 PowerShot G9 X Mark II and Nikon D780 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|12.||Nikon Z6 II||Y||stereo||mono||Y||Y||micro||3.2||Y||-||Y|
It is notable that the D780 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G9X Mark II does not feature such a mic input.
Studio photographers will appreciate that the Nikon D780 (unlike the G9X Mark II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the G9X Mark II and the D780 are recent models that are part of the current product line-up. The G9X Mark II replaced the earlier Canon G9 X, while the D780 followed on from the Nikon D750. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.

If the count of individual advantages (bullet points above) is taken as a guide, the D780 is the clear winner of the contest (25 : 8 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the G9X Mark II and the D780 in practical situations. 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 following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
