Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G9 X and the Olympus XZ-1? 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 G9 X and the Olympus XZ-1 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 size dimensions are rounded to the nearest millimeter.

The G9X can be obtained in two different colors (black, silver), while the XZ-1 is also available in two color-versions, but different ones (black, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus XZ-1 is notably larger (27 percent) than the Canon G9 X. Moreover, the XZ-1 is markedly heavier (32 percent) than the G9X. In this context, it is worth noting that neither the G9X nor the XZ-1 are weather-sealed.

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.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 XZ-1 was somewhat cheaper (by 6 percent) than the G9X at launch, but both cameras fall into the same price category. 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.

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. 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 features an one-inch sensor and the Olympus XZ-1 a 1/1.7-inch sensor. The sensor area in the XZ-1 is 60 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 4.4. The sensor in the G9X has a native 3:2 aspect ratio, while the one in the XZ-1 offers a 4:3 aspect.

With 20MP, the G9X offers a higher resolution than the XZ-1 (10.1MP), but the G9X nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 2.13μm for the XZ-1) due to its larger sensor. Moreover, the G9X is a much more recent model (by 4 years and 9 months) than the XZ-1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

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 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 Olympus XZ-1 are 18.3 x 13.8 inches or 46.5 x 35 cm for good quality, 14.7 x 11 inches or 37.2 x 28 cm for very good quality, and 12.2 x 9.2 inches or 31 x 23.3 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 Olympus XZ-1 are ISO 100 to ISO 6400 (no boost).

In terms of underlying technology, the G9X is build around a BSI-CMOS sensor, while the XZ-1 uses a CCD 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.

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 review, the G9X provides substantially higher image quality than the XZ-1, with an overall score that is 29 points higher. This advantage is based on 2.7 bits higher color depth, 1.9 EV in additional dynamic range, and 2.1 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.

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 G9X provides a higher video resolution than the XZ-1. It can shoot video footage at 1080/60p, while the Olympus is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The G9X and the XZ-1 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the XZ-1 can be equipped with an optional viewfinder – the VF-2. The adjacent table lists some of the other core features of the Canon G9 X and Olympus XZ-1 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 XZ-1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon G9 X and the Olympus XZ-1 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.

Both the G9X and the XZ-1 have zoom lenses built in. The G9X has a 28-84mm f/2.0-4.9 optic and the XZ-1 offers a 28-112mm f/1.8-2.5 (focal lengths in full frame equivalent terms). Hence, the Canon and Olympus provide the same view at the wide-angle end, but the Olympus has more tele-photo reach at the long end. The XZ-1 offers the faster maximum aperture.

Concerning the storage of imaging data, both the G9X and the XZ-1 write their files to SDXC cards. The G9X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the XZ-1 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 G9 X and Olympus XZ-1 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 XZ-1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the G9X and the XZ-1 have been discontinued, but can regularly be found used on ebay. The XZ-1 was replaced by the Olympus XZ-2, while the G9X was followed by the Canon G9 X Mark II. Further information on the features and operation of the G9X and XZ-1 can be found, respectively, in the Canon G9 X Manual (free pdf) or the online Olympus XZ-1 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon G9 X and the Olympus XZ-1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon PowerShot G9 X:

• More detail: Offers more megapixels (20 vs 10.1MP) with a 44% higher linear resolution.
• Better image quality: Scores substantially higher (29 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.7 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (1.9 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (2.1 stops ISO advantage).
• Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 614k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (6 vs 2 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (98x58mm vs 111x65mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 66g or 24 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 4 years and 9 months of technical progress since the XZ-1 launch.

Advantages of the Olympus XZ-1:

• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.0).
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Gets more shots (320 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 January 2011).

If the count of individual advantages (bullet points above) is taken as a guide, the G9X is the clear winner of the match-up (16 : 6 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 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 G9 X and the Olympus XZ-1 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing 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 XZ-1 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning.
