Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G9 X and the Nikon D100? 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 G9 X and the Nikon D100. 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.
The G9X can be obtained in two different colors (black, silver), while the D100 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 D100 is considerably larger (194 percent) than the Canon G9 X. In this context, it is worth noting that neither the G9X nor the D100 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X has a lens built in, whereas the D100 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 D100 and their specifications in the Nikon Lens Catalog.
Concerning battery life, the G9X gets 220 shots out of its NB-13L battery, while the D100 can take 370 images on a single charge of its EN-EL3 power pack. The power pack in the G9X can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

|Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.|
The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G9X was launched at a lower price than the D100, 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 size of the imaging sensor is a crucial determinant 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. 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 G9 X features an one-inch sensor and the Nikon D100 an APS-C sensor. The sensor area in the D100 is 219 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 G9 X offers a higher resolution of 20 megapixels, compared with 6 MP of the Nikon D100. 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 7.85μm for the D100). However, it should be noted that the G9X is much more recent (by 13 years and 7 months) than the D100, 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 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G9X for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inch or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inch or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inch or 46.3 x 30.9 cm. The corresponding values for the Nikon D100 are 15 x 10 inch or 38.2 x 25.4 cm for good quality, 12 x 8 inch or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inch or 25.5 x 16.9 cm for excellent quality prints.
The Canon PowerShot G9 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Nikon D100 are ISO 200 to ISO 800, with the possibility to increase the ISO range to 200-1600.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The G9X indeed provides movie recording capabilities, while the D100 does not. The highest resolution format that the G9X can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D100 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G9X relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon G9 X and Nikon D100 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 G9X has a touchscreen, while the D100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The Canon G9 X 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 G9X writes its imaging data to SDXC cards, while the D100 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 G9 X and Nikon D100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G9X offers wifi support, while the D100 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the G9X and the D100 have been discontinued, but can regularly be found used on eBay. The D100 was replaced by the Nikon D200, while the G9X was followed by the Canon G9 X Mark II. 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? Is there a clear favorite between the Canon G9 X and the Nikon D100? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon PowerShot G9 X:
- More detail: Offers more megapixels (20 vs 6MP) with a 82% higher linear resolution.
- Broader imaging potential: Can record not only still images but also 1080/60p movies.

Arguments in favor of the Nikon D100:
- 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.
- 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 (370 versus 220) 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 February 2002).
If the number of relative strengths (bullet points above) is taken as a guide, the G9X is the clear winner of the match-up (16 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 G9 X and the Nikon D100 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the G9X and the D100 in practical situations. 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 hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.
The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
