Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G5 X and the Leica M10 (Typ 3656)? 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 G5 X and the Leica M10 are illustrated 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 size dimensions are rounded to the nearest millimeter.

The M10 can be obtained in two different colors (black, silver), while the G5X 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 Leica M10 is notably larger (31 percent) than the Canon G5 X. It is noteworthy in this context that the M10 is splash and dust-proof, while the G5X does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G5X has a lens built in, whereas the M10 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 M10 and their specifications in the Leica M Lens Catalog.

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. 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 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 lower price than the M10, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G5 X features an one-inch sensor and the Leica M10 a full frame sensor. The sensor area in the M10 is 638 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 23.8MP, the M10 offers a higher resolution than the G5X (20MP), but the M10 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 2.41μm for the G5X) due to its larger sensor. Moreover, the M10 is a somewhat more recent model (by 1 year and 3 months) than the G5X, and its sensor might 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 M10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica M10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10 for good quality output (200 dots per inch) amounts to 29.8 x 20 inches or 75.6 x 50.7 cm, for very good quality (250 dpi) 23.8 x 16 inches or 60.5 x 40.6 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inches or 50.4 x 33.8 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 M10 (Typ 3656) are ISO 100 to ISO 50000 (no boost).

In terms of underlying technology, the G5X is build around a BSI-CMOS sensor, while the M10 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 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 M10 offers substantially better image quality than the G5X (overall score 24 points higher). The advantage is based on 3 bits higher color depth, 0.9 EV in additional dynamic range, and 2.2 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The G5X indeed provides movie recording capabilities, while the M10 does not. The highest resolution format that the G5X can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G5X has an electronic viewfinder (2360k dots), while the M10 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Canon G5 X and Leica M10 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The G5X has one, while the M10 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 Canon G5 X and the Leica M10 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.

Concerning the storage of imaging data, both the G5X and the M10 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of 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 M10 (Typ 3656) and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G5X and the M10 have been discontinued, but can regularly be found used on ebay. The G5X was replaced by the Canon G5 X Mark II, while the M10 was followed by the Leica M11. Further information on the features and operation of the G5X and M10 can be found, respectively, in the Canon G5 X Manual (free pdf) or the online Leica M10 Manual.

Review summary

So how do things add up? Is the Canon G5 X better than the Leica M10 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon PowerShot G5 X:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Broader imaging potential: Can record not only still images but also 1080/60p movies.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (5.9 vs 5 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the M10 requires a separate lens.
• More compact: Is smaller (112x76mm vs 139x80mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the M10).
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• 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 at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been on the market for longer (launched in October 2015).

Advantages of the Leica M10 (Typ 3656):

• More detail: Has more megapixels (23.8 vs 20MP), which boosts linear resolution by 9%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (24 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (3 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.2 stops ISO advantage).
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More flexible: Takes interchangeable lenses and can thus be used with different optics.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More modern: Was introduced somewhat (1 year and 3 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the G5X is the clear winner of the match-up (16 : 12 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 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.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the G5X and the M10 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 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 are only valid when referring to cameras in the same category and of the same age.
