Canon G3 X vs Panasonic LX7
The Canon PowerShot G3 X and the Panasonic Lumix DMC-LX7 are two digital cameras that were revealed to the public, respectively, in June 2015 and July 2012. Both the G3X and the LX7 are fixed lens compact cameras that are based on an one-inch (G3X) and a 1/1.7-inch (LX7) sensor. The Canon has a resolution of 20 megapixels, whereas the Panasonic provides 10 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 G3 X and the Panasonic Lumix DMC-LX7? 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.
An illustration of the physical size and weight of the Canon G3 X and the Panasonic LX7 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The LX7 can be obtained in two different colors (black, white), while the G3X 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 Panasonic LX7 is notably smaller (20 percent) than the Canon G3 X. Moreover, the LX7 is substantially lighter (59 percent) than the G3X. It is worth mentioning in this context that the G3X is splash and dust resistant, while the LX7 does not feature any corresponding weather-sealing.

|Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.|
The price is, of course, an important factor in any camera decision. 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 LX7 was launched at a markedly lower price (by 50 percent) than the G3X, 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.
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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon G3 X features an one-inch sensor and the Panasonic LX7 a 1/1.7-inch sensor. The sensor area in the LX7 is 64 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 4.65. The sensor in the G3X has a native 3:2 aspect ratio, while the one in the LX7 offers a 4:3 aspect. The LX7 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.
With 20MP, the G3X offers a higher resolution than the LX7 (10MP), but the G3X nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 2.05μm for the LX7) due to its larger sensor. Moreover, the G3X is a much more recent model (by 2 years and 11 months) than the LX7, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon G3 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G3X 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 Panasonic LX7 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.
The Canon PowerShot G3 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 Panasonic Lumix DMC-LX7 are ISO 80 to ISO 6400, with the possibility to increase the ISO range to 80-12800.
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"). Of the two cameras under review, the G3X provides substantially higher image quality than the LX7, with an overall score that is 13 points higher. This advantage is based on 0.7 bits higher color depth, 0.6 EV in additional dynamic range, and 1.8 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a range of features. The G3X and the LX7 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. However, optional viewfinders – the EVF-DC1 for the G3X and the DMW-LVF2 for the LX7 – are available as accessories. The adjacent table lists some of the other core features of the Canon G3 X and Panasonic LX7 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 G3X has a touchscreen, while the LX7 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G3X 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 LX7 does not have a selfie-screen.
The Panasonic LX7 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.
Both the G3X and the LX7 have zoom lenses built in. The G3X has a 24-600mm f/2.8-5.6 optic and the LX7 offers a 24-90mm f/1.4-2.3 (focal lengths in full frame equivalent terms). Hence, the Canon and Panasonic provide the same view at the wide-angle end, but the Panasonic has less tele-photo reach at the long end. The LX7 offers the faster maximum aperture.
Concerning the storage of imaging data, both the G3X and the LX7 write their files to SDXC cards. The G3X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the LX7 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 G3 X and Panasonic Lumix DMC-LX7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G3X has a microphone port, which is missing on the LX7. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The G3X is a recent model that features in the current product line-up of Canon. In contrast, the LX7 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the LX7 was succeeded by the Panasonic LX10. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.
So what is the bottom line? Which of the two cameras – the Canon G3 X or the Panasonic LX7 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the number of relative strengths (bullet points above) is taken as a guide, the G3X is the clear winner of the match-up (17 : 9 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 G3 X and the Panasonic LX7 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Travel-Zoom 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 G3X and the LX7 in practical situations. 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.
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], 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 above review scores should be interpreted 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
