Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon G9 X Mark II and the Nikon D4. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The G9X Mark II can be obtained in two different colors (black, silver), while the D4 is only available in black.

Size Canon G9 X Mark II vs Nikon D4
Compare G9X Mark II versus D4 top
Comparison G9X Mark II or D4 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D4 is considerably larger (342 percent) than the Canon G9 X Mark II. It is noteworthy in this context that the D4 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 D4 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 D4 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 D4 can take 2600 images on a single charge of its EN-EL18 power pack. As can be seen in the images above, the D4 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the G9X 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. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 Mark II was launched at a lower price than the D4, 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.

Sensor comparison

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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G9 X Mark II features an one-inch sensor and the Nikon D4 a full frame sensor. The sensor area in the D4 is 641 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.

Canon G9 X Mark II and Nikon D4 sensor measures

Despite having a smaller sensor, the Canon G9 X Mark II offers a higher resolution of 20 megapixels, compared with 16.2 MP of the Nikon D4. 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 7.29μm for the D4). However, it should be noted that the G9X Mark II is much more recent (by 5 years) than the D4, 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 G9 X Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G9X 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 D4 are 24.6 x 16.4 inches or 62.6 x 41.7 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.3 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.8 cm for excellent quality prints.

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 D4 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-204800.

In terms of underlying technology, the G9X Mark II is build around a BSI-CMOS sensor, while the D4 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.

G9X Mark II versus D4 MP

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"). Of the two cameras under consideration, the D4 offers substantially better image quality than the G9X Mark II (overall score 24 points higher). The advantage is based on 2.8 bits higher color depth, 0.6 EV in additional dynamic range, and 2.5 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.

One difference between the cameras concerns the presence of an on-board flash. The G9X Mark II has one, while the D4 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 D4 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.

The G9X Mark II writes its imaging data to SDXC cards, while the D4 uses Compact Flash or XQD cards. The D4 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.

Connectivity comparison

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 D4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G9X Mark II offers wifi support, while the D4 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Nikon D4 (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 D4 have been discontinued, but can regularly be found used on ebay. The D4 was replaced by the Nikon D4S, while the G9X Mark II does not have a direct successor. Further information on the features and operation of the G9X Mark II and D4 can be found, respectively, in the Canon G9 X Mark II Manual (free pdf) or the online Nikon D4 Manual.

ilogo

Advantages of the Nikon D4:

  • Better image quality: Scores substantially higher (24 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.8 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.5 stops ISO advantage).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (11 vs 8.2 flaps/sec) to capture the decisive moment.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Gets more shots (2600 versus 235) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been around for much longer (launched in January 2012).

If the number of relative strengths (bullet points above) is taken as a guide, the D4 is the clear winner of the contest (19 : 15 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.

G9X Mark II 15:19 D4

How about other alternatives? Do the specifications of the Canon G9 X Mark II and the Nikon D4 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 says little about, for example, the shooting experience and imaging performance of the G9X Mark II and the D4 in practical situations. 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.

Expert reviews

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 (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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
