Canon G7 X Mark III vs Leica C-LUX
The Canon PowerShot G7 X Mark III and the Leica C-LUX are two digital cameras that were announced, respectively, in July 2019 and June 2018. Both the G7X Mark III and the C-LUX are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixels.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G7 X Mark III and the Leica C-LUX? 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.
The physical size and weight of the Canon G7 X Mark III and the Leica C-LUX are illustrated 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.
The G7X Mark III can be obtained in two different colors (black, silver), while the C-LUX is also available in two color-versions, but different ones (gold, blue).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica C-LUX is notably larger (18 percent) than the Canon G7 X Mark III. Moreover, the C-LUX is markedly heavier (12 percent) than the G7X Mark III. In this context, it is worth noting that neither the G7X Mark III nor the C-LUX are weather-sealed.
The battery packs of both cameras can be charged via USB, which can be very convenient 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.

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 G7X Mark III was launched at a markedly lower price (by 29 percent) than the C-LUX, which puts it into a different market segment. 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.
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. 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.
Both cameras under consideration feature an one-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 2.7. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixels. This similarity in sensor specs implies that both the G7X Mark III and the C-LUX have the same pixel density, as well as the same pixel size. It should, however, be noted that the G7X Mark III is a somewhat more recent model (by 1 year) than the C-LUX, and its sensor might have benefitted from technological advances during this time.
The Canon PowerShot G7 X Mark III 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 C-LUX are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
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 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).
Beyond body and sensor, cameras can and do differ across a range of features. For example, the C-LUX has an electronic viewfinder (2330k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G7X Mark III relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon G7 X Mark III and Leica C-LUX in connection with corresponding information for a sample of similar cameras.

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, both cameras under consideration feature an 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 G7 X Mark III and the Leica C-LUX 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 G7X Mark III and the C-LUX have zoom lenses built in. The G7X Mark III has a 24-100mm f/1.8-2.8 optic and the C-LUX offers a 24-360mm f/3.3-6.4 (focal lengths in full frame equivalent terms). Hence, the Canon and Leica provide the same view at the wide-angle end, but the Leica has more tele-photo reach at the long end. The G7X Mark III offers the faster maximum aperture.
Concerning the storage of imaging data, both the G7X Mark III and the C-LUX 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.
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 G7 X Mark III and Leica C-LUX and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X Mark III has a microphone port, which is missing on the C-LUX. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the G7X Mark III and the C-LUX are recent models that are part of the current product line-up. The G7X Mark III replaced the earlier Canon G7X Mark II, while the C-LUX does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Leica websites.
So what is the bottom line? Is there a clear favorite between the Canon G7 X Mark III and the Leica C-LUX? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon PowerShot G7 X Mark III:
- Better sound: Can connect to an external microphone for higher quality sound recording.
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (30 vs 10 flaps/sec) to capture the decisive moment.
- Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/3.3).
- More compact: Is smaller (105x61mm vs 113x67mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 36g or 11 percent) and hence easier to carry around.
- Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 1 year after the C-LUX).
Reasons to prefer the Leica C-LUX:
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (1240k vs 1040k dots).
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Longer lasting: Gets more shots (370 versus 235) out of a single battery charge.
- More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
- More heavily discounted: Has been on the market for longer (launched in June 2018).
If the count of relative strengths (bullet points above) is taken as a measure, the G7X Mark III is the clear winner of the match-up (11 : 6 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.
How about other alternatives? Do the specifications of the Canon G7 X Mark III and the Leica C-LUX place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G7X Mark III or the C-LUX perform in practice. 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.
This is why hands-on reviews by experts 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], 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 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
