Canon G7 X Mark II vs Nikon D3400
The Canon PowerShot G7 X Mark II and the Nikon D3400 are two digital cameras that were officially introduced, respectively, in February 2016 and August 2016. The G7X Mark II is a fixed lens compact, while the D3400 is a DSLR. The cameras are based on an one-inch (G7X Mark II) and an APS-C (D3400) sensor. The Canon has a resolution of 20 megapixels, whereas the Nikon provides 24 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 G7 X Mark II and the Nikon D3400? 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 side-by-side display below illustrates the physical size and weight of the Canon G7 X Mark II and the Nikon D3400. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
The D3400 can be obtained in two different colors (black, red), while the G7X 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 Nikon D3400 is considerably larger (88 percent) than the Canon G7 X Mark II. In this context, it is worth noting that neither the G7X Mark II nor the D3400 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X Mark II has a lens built in, whereas the D3400 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 D3400 and their specifications in the Nikon Lens Catalog.
Concerning battery life, the G7X Mark II gets 265 shots out of its NB-13L battery, while the D3400 can take 1200 images on a single charge of its EN-EL14a power pack. The power pack in the G7X Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision 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. 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.
The size of the sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G7 X Mark II features an one-inch sensor and the Nikon D3400 an APS-C sensor. The sensor area in the D3400 is 216 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the D3400 offers a higher resolution than the G7X Mark II (20MP), but the D3400 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 2.41μm for the G7X Mark II) due to its larger sensor. Moreover, the D3400 is a somewhat more recent model (by 5 months) than the G7X Mark II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the D3400 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D3400 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3400 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon G7 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 Canon PowerShot G7 X Mark II has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Nikon D3400 are ISO 100 to ISO 25600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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, 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 D3400 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G7X Mark II relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon G7 X Mark II and Nikon D3400 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X Mark II has a touchscreen, while the D3400 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G7X 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 D3400 does not have a selfie-screen.
The Canon G7 X Mark II has 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 G7X Mark II and the D3400 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 PowerShot G7 X Mark II and Nikon D3400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X Mark II offers wifi support, while the D3400 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the G7X Mark II and the D3400 have been discontinued, but can regularly be found used on eBay. The G7X Mark II was replaced by the Canon G7 X Mark III, while the D3400 was followed by the Nikon D3500. 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 G7X Mark II emerges as the winner of the contest (15 : 13 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 G7 X Mark II and the Nikon D3400 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
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 G7X Mark II or the D3400 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 why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
