Canon G7 X Mark II vs Nikon D90
The Canon PowerShot G7 X Mark II and the Nikon D90 are two digital cameras that were officially introduced, respectively, in February 2016 and August 2008. The G7X Mark II is a fixed lens compact, while the D90 is a DSLR. The cameras are based on an one-inch (G7X Mark II) and an APS-C (D90) sensor. The Canon has a resolution of 20 megapixels, whereas the Nikon provides 12.2 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 D90? 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 D90. 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 dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D90 is considerably larger (110 percent) than the Canon G7 X Mark II. In this context, it is worth noting that neither the G7X Mark II nor the D90 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 D90 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 D90 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 D90 can take 850 images on a single charge of its EN-EL3e 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. 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 G7X Mark II was launched at a lower price than the D90, 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. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 D90 an APS-C sensor. The sensor area in the D90 is 222 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.
Despite having a smaller sensor, the Canon G7 X Mark II offers a higher resolution of 20 megapixels, compared with 12.2 MP of the Nikon D90. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 5.53μm for the D90). However, it should be noted that the G7X Mark II is much more recent (by 7 years and 5 months) than the D90, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon G7 X Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X Mark II for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Nikon D90 are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 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 D90 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 200-6400.
In terms of underlying technology, the G7X Mark II is build around a BSI-CMOS sensor, while the D90 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
For many cameras, data on sensor performance has been reported by DXO Mark. 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. 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G7X Mark II provides a higher video resolution than the D90. It can shoot video footage at 1080/60p, while the Nikon is limited to 720/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D90 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 adjacent table lists some of the other core features of the Canon G7 X Mark II and Nikon D90 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X Mark II has a touchscreen, while the D90 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 D90 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.
The G7X Mark II writes its imaging data to SDXC cards, while the D90 uses SDHC cards. The G7X Mark II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D90 cannot take advantage of Ultra High Speed SD 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 G7 X Mark II and Nikon D90 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 D90 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 D90 have been discontinued, but can regularly be found used on ebay. The D90 was replaced by the Nikon D7000, while the G7X Mark II was followed by the Canon G7 X Mark III. 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.
So what conclusions can be drawn? Is there a clear favorite between the Canon G7 X Mark II and the Nikon D90? Which camera is better? The listing below highlights the relative strengths of the two models.

- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (850 versus 265) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been around for much longer (launched in August 2008).
If the number of relative strengths (bullet points above) is taken as a guide, the G7X Mark II is the clear winner of the match-up (18 : 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. 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.
How about other alternatives? Do the specifications of the Canon G7 X Mark II and the Nikon D90 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G7X Mark II or the D90. 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 where reviews by experts come in. 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.

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