Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G9 X Mark II and the Leica X1? 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

An illustration of the physical size and weight of the Canon G9 X Mark II and the Leica X1 is provided in the side-by-side display below. 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 measures are rounded to the nearest millimeter.

Both cameras are available in two different colors (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica X1 is notably larger (31 percent) than the Canon G9 X Mark II. Moreover, the X1 is substantially heavier (49 percent) than the G9X Mark II. In this context, it is worth noting that neither the G9X Mark II nor the X1 are weather-sealed.

Concerning battery life, the G9X Mark II gets 235 shots out of its Canon NB-13L battery, while the X1 can take 260 images on a single charge of its Leica BP-DC8 power pack. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G9X Mark II was launched at a markedly lower price (by 73 percent) than the X1, which puts it into a different market segment. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G9 X Mark II features an one-inch sensor and the Leica X1 an APS-C sensor. The sensor area in the X1 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 Mark II offers a higher resolution of 20 megapixels, compared with 12.2 MP of the Leica X1. 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 5.51μm for the X1). However, it should be noted that the G9X Mark II is much more recent (by 7 years and 3 months) than the X1, 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 Leica X1 are 21.4 x 14.3 inches or 54.3 x 36.3 cm for good quality, 17.1 x 11.4 inches or 43.4 x 29 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.2 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 Leica X1 are ISO 100 to ISO 3200 (no boost).

In terms of underlying technology, the G9X Mark II is build around a BSI-CMOS sensor, while the X1 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.

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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G9X Mark II has a touchscreen, while the X1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon G9 X Mark II 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 Mark II is equipped with a zoom lens, while the X1 comes with a built-in prime. The G9X Mark II has a 28-84mm f/2.0-4.9 optic and the X1 offers a 36mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Leica. The G9X Mark II offers the faster maximum aperture.

The G9X Mark II writes its imaging data to SDXC cards, while the X1 uses SDHC cards. The G9X Mark II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X1 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 Mark II and Leica X1 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 X1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the G9X Mark II and the X1 have been discontinued, but can regularly be found used on ebay. The X1 was replaced by the Leica X2, while the G9X Mark II does not have a direct successor. Further information on the features and operation of the G9X Mark II and X1 can be found, respectively, in the Canon G9 X Mark II Manual (free pdf) or the online Leica X1 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon G9 X Mark II and the Leica X1? Which camera is better? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon PowerShot G9 X Mark II:

• More detail: Offers more megapixels (20 vs 12.2MP) with a 28% higher linear resolution.

• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (8.2 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/2.8).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More compact: Is smaller (98x58mm vs 124x60mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 100g or 33 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• 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.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.

• More affordable: Was introduced into a lower priced category (73 percent cheaper at launch).
• More modern: Reflects 7 years and 3 months of technical progress since the X1 launch.

Advantages of the Leica X1:

• Longer lasting: Gets more shots (260 versus 235) out of a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More heavily discounted: Has been around for much longer (launched in September 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the G9X Mark II is the clear winner of the match-up (19 : 4 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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 G9 X Mark II and the Leica X1 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Prime Lens Compact 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G9X Mark II or the X1. 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 why hands-on reviews by experts are important. 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
