Canon G16 vs Nikon D2X
The Canon PowerShot G16 and the Nikon D2X are two digital cameras that were announced, respectively, in August 2013 and September 2004. The G16 is a fixed lens compact, while the D2X is a DSLR. The cameras are based on a 1/1.7-inch (G16) and an APS-C (D2X) sensor. The Canon has a resolution of 12 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 G16 and the Nikon D2X? 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 G16 and the Nikon D2X. 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 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 D2X is considerably larger (186 percent) than the Canon G16. It is noteworthy in this context that the D2X is splash and dust-proof, while the G16 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G16 has a lens built in, whereas the D2X 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 D2X and their specifications in the Nikon Lens Catalog.
Concerning battery life, the G16 gets 360 shots out of its NB-10L battery, while the D2X can take 3800 images on a single charge of its EN-EL4a power pack. As can be seen in the images above, the D2X has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G16 was launched at a lower price than the D2X, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon G16 features a 1/1.7-inch sensor and the Nikon D2X an APS-C sensor. The sensor area in the D2X is 786 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.65 and 1.5. The sensor in the G16 has a native 4:3 aspect ratio, while the one in the D2X offers a 3:2 aspect.
With 12.2MP, the D2X offers a higher resolution than the G16 (12MP), but the D2X nevertheless has larger individual pixels (pixel pitch of 5.52μm versus 1.87μm for the G16) due to its larger sensor. However, the G16 is a much more recent model (by 8 years and 11 months) than the D2X, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The Canon PowerShot G16 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Nikon D2X are ISO 100 to ISO 800, with the possibility to increase the ISO range to 100-3200.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 D2X has a markedly higher DXO score than the G16 (overall score 5 points higher), which will translate into better image quality. The advantage is based on 1.1 bits higher color depth, 0.8 EV of lower dynamic range, and 1 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.
|3.||Canon G1 X Mark II||1.5-inch||13.0||4160||3120||1080/30p||21.5||10.8||581||58|
|5.||Canon G1 X||1.5-inch||14.2||4352||3264||1080/24p||21.7||10.8||644||60|
|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras are not only capable of taking still images, but can also record movies. The G16 indeed provides movie recording capabilities, while the D2X does not. The highest resolution format that the G16 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The G16 and the D2X 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 G16 and Nikon D2X along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The G16 has one, while the D2X does not. While the built-in flash of the G16 is not very powerful, it can at times be useful as a fill-in light.
The Canon G16 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 G16 writes its imaging data to SDXC cards, while the D2X uses Compact Flash 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 G16 and Nikon D2X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G16 offers wifi support, while the D2X 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 D2X (unlike the G16) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The G16 is a recent model that features in the current product line-up of Canon. In contrast, the D2X has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D2X was succeeded by the Nikon D2Xs. 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 how do things add up? Which of the two cameras – the Canon G16 or the Nikon D2X – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon PowerShot G16:
- More dynamic range: Captures a larger spectrum of light and dark details (0.8 EV of extra DR).
- Broader imaging potential: Can record not only still images but also 1080/60p movies.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (922k vs 235k dots).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Comes with a built-in lens, while the D2X requires a separate lens.
- More compact: Is smaller (109x76mm vs 158x150mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the D2X).
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 8 years and 11 months of technical progress since the D2X launch.
Arguments in favor of the Nikon D2X:
- Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.1 bits more color depth).
- Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (5 vs 2.2 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 (3800 versus 360) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been around for much longer (launched in September 2004).
If the count of relative strengths (bullet points above) is taken as a measure, the G16 comes out slightly ahead of the D2X (13 : 12 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 G16 and the Nikon D2X 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 incomplete and does no justice, for example, to the way the G16 or the D2X perform in practice. 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 expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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, please note that some of the review sites have changed their methodology and reporting over time.
