Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G16 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.

Body comparison

The physical size and weight of the Canon G16 and the Nikon D90 are illustrated in the side-by-side display below. 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 D90 is considerably larger (64 percent) than the Canon G16. In this context, it is worth noting that neither the G16 nor the D90 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G16 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 G16 gets 360 shots out of its Canon NB-10L battery, while the D90 can take 850 images on a single charge of its Nikon EN-EL3e power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Any camera decision will naturally be influenced heavily by the price. 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 D90, 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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G16 features a 1/1.7-inch sensor and the Nikon D90 an APS-C sensor. The sensor area in the D90 is 788 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 D90 offers a 3:2 aspect.

With 12.2MP, the D90 offers a higher resolution than the G16 (12MP), but the D90 nevertheless has larger individual pixels (pixel pitch of 5.53μm versus 1.87μm for the G16) due to its larger sensor. However, the G16 is a much more recent model (by 4 years and 11 months) than the D90, 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 D90 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 200-6400.

In terms of underlying technology, the G16 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. Of the two cameras under consideration, the D90 offers substantially better image quality than the G16 (overall score 19 points higher). The advantage is based on 1.7 bits higher color depth, 0.8 EV in additional dynamic range, and 2.1 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G16 provides a higher video resolution than the D90. It can shoot video footage at 1080/60p, while the Nikon is limited to 720/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The G16 and the D90 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 following table reports on some other key feature differences and similarities of the Canon G16, the Nikon D90, and comparable cameras.

One feature that is present on the D90, but is missing on the G16 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

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 D90 uses SDHC cards. The G16 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.

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 G16 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 G16 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 G16 and the D90 have been discontinued, but can regularly be found used on ebay. The D90 was replaced by the Nikon D7000, while the G16 does not have a direct successor. Further information on the features and operation of the G16 and D90 can be found, respectively, in the Canon G16 Manual (free pdf) or the online Nikon D90 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon G16 and the Nikon D90? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon PowerShot G16:

• Better video: Provides higher definition movie capture (1080/60p vs 720/24p).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with a built-in lens, while the D90 requires a separate lens.
• More compact: Is smaller (109x76mm vs 132x103mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D90).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 4 years and 11 months of technical progress since the D90 launch.

Arguments in favor of the Nikon D90:

• Better image quality: Scores substantially higher (19 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.7 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.1 stops ISO advantage).
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster burst: Shoots at higher frequency (4.5 vs 2.2 flaps/sec) to capture the decisive moment.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (850 versus 360) out of a single battery charge.
• More heavily discounted: Has been around for much longer (launched in August 2008).

If the count of relative strengths (bullet points above) is taken as a measure, the G16 comes out slightly ahead of the D90 (10 : 9 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G16 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.

Expert reviews

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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
