Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G15 and the Nikon D850? 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 G15 and the Nikon D850. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D850 is considerably larger (123 percent) than the Canon G15. It is noteworthy in this context that the D850 is splash and dust-proof, while the G15 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G15 has a lens built in, whereas the D850 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 D850 and their specifications in the Nikon Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 G15 was launched at a lower price than the D850, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 G15 features a 1/1.7-inch sensor and the Nikon D850 a full frame sensor. The sensor area in the D850 is 1895 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 1.0. The sensor in the G15 has a native 4:3 aspect ratio, while the one in the D850 offers a 3:2 aspect.
With 45.4MP, the D850 offers a higher resolution than the G15 (12MP), but the D850 nevertheless has larger individual pixels (pixel pitch of 4.35μm versus 1.89μm for the G15) due to its larger sensor. Moreover, the D850 is a much more recent model (by 4 years and 10 months) than the G15, and its sensor will 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 D850 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D850 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D850 for good quality output (200 dots per inch) amounts to 41.3 x 27.5 inches or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inches or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inches or 69.9 x 46.6 cm. The corresponding values for the Canon G15 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Canon PowerShot G15 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Nikon D850 are ISO 64 to ISO 25600, with the possibility to increase the ISO range to 32-102400.
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. Of the two cameras under consideration, the D850 offers substantially better image quality than the G15 (overall score 54 points higher). The advantage is based on 6.5 bits higher color depth, 3.3 EV in additional dynamic range, and 4 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.
|Nikon D850||Full Frame||45.4||8256||5504||4K/30p||26.4||14.8||2660||100|
|Canon 5DS||Full Frame||50.3||8688||5792||1080/30p||24.7||12.4||2381||87|
|Canon 5DS R||Full Frame||50.3||8688||5792||1080/30p||24.6||12.4||2308||86|
|Nikon D5||Full Frame||20.7||5588||3712||4K/30p||25.1||12.3||2343||88|
|Nikon D810||Full Frame||36.2||7360||4912||1080/60p||25.7||14.8||2853||97|
|Nikon D610||Full Frame||24.2||6016||4016||1080/30p||25.1||14.4||2925||94|
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, but the D850 provides a better video resolution than the G15. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. The G15 and the D850 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The adjacent table lists some of the other core features of the Canon G15 and Nikon D850 along with similar information for a selection of comparators.
|Canon 5DS R||optical||Y||3.2||1040||fixed||n||1/8000s||5.0||n||n|
One difference between the cameras concerns the presence of an on-board flash. The G15 has one, while the D850 does not. While the built-in flash of the G15 is not very powerful, it can at times be useful as a fill-in light.
The Nikon D850 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 G15 writes its imaging data to SDXC cards, while the D850 uses SDHC or XQD cards. The D850 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G15 only has one slot. The D850 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G15 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 G15 and Nikon D850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Canon 5DS R||Y||mono||mono||Y||-||mini||3.0||-||-||-|
It is notable that the D850 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G15 does not provide wifi capability.
Studio photographers will appreciate that the Nikon D850 (unlike the G15) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The D850 is a recent model that features in the current product line-up of Nikon. In contrast, the G15 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the G15 was succeeded by the Canon G16. 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 G15 and the Nikon D850? Which camera is better? The listing below highlights the relative strengths of the two models.

If the number of relative strengths (bullet points above) is taken as a guide, the D850 is the clear winner of the contest (28 : 8 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 G15 and the Nikon D850 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 G15 or the D850. 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 (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.

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.
