Canon G7 X vs Leica Digilux 3
The Canon PowerShot G7 X and the Leica Digilux 3 are two digital cameras that were revealed to the public, respectively, in September 2014 and September 2006. The G7X is a fixed lens compact, while the Digilux 3 is a DSLR. The cameras are based on an one-inch (G7X) and a Four Thirds (Digilux 3) sensor. The Canon has a resolution of 20 megapixels, whereas the Leica provides 7.4 MP.
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 and the Leica Digilux 3? 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 and the Leica Digilux 3 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 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 Digilux 3 is considerably larger (106 percent) than the Canon G7 X. In this context, it is worth noting that neither the G7X nor the Digilux 3 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X has a lens built in, whereas the Digilux 3 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 Digilux 3 and their specifications in the Four Thirds Lens Catalog.
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 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 G7X was launched at a lower price than the Digilux 3, 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.
The size of the imaging sensor is a crucial determinant 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon G7 X features an one-inch sensor and the Leica Digilux 3 a Four Thirds sensor. The sensor area in the Digilux 3 is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the G7X has a native 3:2 aspect ratio, while the one in the Digilux 3 offers a 4:3 aspect.
Despite having a smaller sensor, the Canon G7 X offers a higher resolution of 20 megapixels, compared with 7.4 MP of the Leica Digilux 3. 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 Digilux 3). However, it should be noted that the G7X is much more recent (by 8 years) than the Digilux 3, 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 G7 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X 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 Digilux 3 are 15.7 x 11.8 inches or 39.8 x 29.9 cm for good quality, 12.5 x 9.4 inches or 31.9 x 23.9 cm for very good quality, and 10.5 x 7.8 inches or 26.6 x 19.9 cm for excellent quality prints.
The Canon PowerShot G7 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Leica Digilux 3 are ISO 100 to ISO 1600 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 are not only capable of taking still images, but also of capturing video footage. The G7X indeed provides movie recording capabilities, while the Digilux 3 does not. The highest resolution format that the G7X can use is 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the Digilux 3 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G7X relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon G7 X and Leica Digilux 3 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 G7X has a touchscreen, while the Digilux 3 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G7X has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the Digilux 3 does not have a selfie-screen.
The Canon G7 X 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.
Concerning the storage of imaging data, both the G7X and the Digilux 3 write their files to SDXC cards. The G7X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the Digilux 3 cannot take advantage of Ultra High Speed SD cards.
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 and Leica Digilux 3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

If the count of relative strengths (bullet points above) is taken as a measure, the G7X is the clear winner of the match-up (18 : 7 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 G7 X and the Leica Digilux 3 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR 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 or the Digilux 3 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
