Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G5 X and the Leica Q2? 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 G5 X and the Leica Q2 is provided in the side-by-side display below. 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 Leica Q2 is notably larger (22 percent) than the Canon G5 X. Moreover, the Q2 is substantially heavier (103 percent) than the G5X. It is noteworthy in this context that the Q2 is splash and dust-proof, while the G5X does not feature any corresponding weather-sealing.

Concerning battery life, the G5X gets 210 shots out of its Canon NB-13L battery, while the Q2 can take 370 images on a single charge of its Leica BP-SCL4 power pack. The power pack in the G5X 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. 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.

Any camera decision will obviously take relative prices into account. 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 G5X was launched at a markedly lower price (by 84 percent) than the Q2, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G5 X features an one-inch sensor and the Leica Q2 a full frame sensor. The sensor area in the Q2 is 645 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 46.7MP, the Q2 offers a higher resolution than the G5X (20MP), but the Q2 nevertheless has larger individual pixels (pixel pitch of 4.30μm versus 2.41μm for the G5X) due to its larger sensor. Moreover, the Q2 is a much more recent model (by 3 years and 4 months) than the G5X, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the Q2 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica Q2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Q2 for good quality output (200 dots per inch) amounts to 41.8 x 27.9 inches or 106.3 x 70.9 cm, for very good quality (250 dpi) 33.5 x 22.3 inches or 85 x 56.7 cm, and for excellent quality (300 dpi) 27.9 x 18.6 inches or 70.8 x 47.3 cm. The corresponding values for the Canon G5 X are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The Canon PowerShot G5 X has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Leica Q2 are ISO 50 to ISO 50000 (no boost).

In terms of underlying technology, the G5X is build around a BSI-CMOS sensor, while the Q2 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 Q2 offers substantially better image quality than the G5X (overall score 34 points higher). The advantage is based on 5 bits higher color depth, 1.2 EV in additional dynamic range, and 2.4 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 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 Q2 provides a better video resolution than the G5X. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the Q2 offers a substantially higher resolution than the one in the G5X (3680k vs 2360k dots). The following table reports on some other key feature differences and similarities of the Canon G5 X, the Leica Q2, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The G5X has one, while the Q2 does not. While the built-in flash of the G5X is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the Q2 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Canon G5 X and the Leica Q2 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.

The G5X is equipped with a zoom lens, while the Q2 comes with a built-in prime. The G5X has a 24-100mm f/1.8-2.8 optic and the Q2 offers a 28mm f/1.7 (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 Q2 offers the faster maximum aperture.

Concerning the storage of imaging data, both the G5X and the Q2 write their files to SDXC cards. The Q2 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G5X can use UHS-I cards (up to 104 MB/s).

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 G5 X and Leica Q2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The Q2 is a recent model that features in the current product line-up of Leica. In contrast, the G5X has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the G5X was succeeded by the Canon G5 X Mark II. Further information on the features and operation of the G5X and Q2 can be found, respectively, in the Canon G5 X Manual (free pdf) or the online Leica Q2 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon G5 X or the Leica Q2 – 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.

Arguments in favor of the Canon PowerShot G5 X:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More compact: Is smaller (112x76mm vs 130x80mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 365g or 51 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (84 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in October 2015).

Reasons to prefer the Leica Q2:

• More detail: Has more megapixels (46.7 vs 20MP), which boosts linear resolution by 53%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (34 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (5 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.2 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.4 stops ISO advantage).
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• More detailed viewfinder: Has higher resolution electronic viewfinder (3680k vs 2360k dots).
• Faster burst: Shoots at higher frequency (10 vs 5.9 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.7 vs f/1.8).
• Longer lasting: Gets more shots (370 versus 210) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More modern: Reflects 3 years and 4 months of technical progress since the G5X launch.

If the number of relative strengths (bullet points above) is taken as a guide, the Q2 is the clear winner of the contest (17 : 11 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 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 G5 X and the Leica Q2 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 says little about, for example, the shooting experience and imaging performance of the G5X and the Q2 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.

Expert reviews

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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
