Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G3 X and the Panasonic Lumix DMC-LX5? 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 G3 X and the Panasonic LX5 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 LX5 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 LX5 is notably smaller (25 percent) than the Canon G3 X. Moreover, the LX5 is substantially lighter (63 percent) than the G3X. It is worth mentioning in this context that the G3X is splash and dust resistant, while the LX5 does not feature any corresponding weather-sealing.

Concerning battery life, the G3X gets 300 shots out of its Canon NB-10L battery, while the LX5 can take 400 images on a single charge of its Panasonic DMW-BCJ13 power pack.

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 LX5 was launched at a markedly lower price (by 50 percent) than the G3X, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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.

Of the two cameras under consideration, the Canon G3 X features an one-inch sensor and the Panasonic LX5 a 1/1.7-inch sensor. The sensor area in the LX5 is 60 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 4.4. The sensor in the G3X has a native 3:2 aspect ratio, while the one in the LX5 offers a 4:3 aspect. The LX5 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 LX5 (10MP), but the G3X nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 2.14μm for the LX5) due to its larger sensor. Moreover, the G3X is a much more recent model (by 4 years and 10 months) than the LX5, 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 LX5 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-LX5 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.

In terms of underlying technology, the G3X is build around a BSI-CMOS sensor, while the LX5 uses a CCD 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 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 LX5, with an overall score that is 22 points higher. This advantage is based on 1.8 bits higher color depth, 1.5 EV in additional dynamic range, and 2 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, but the G3X provides a higher video resolution than the LX5. It can shoot video footage at 1080/60p, while the Panasonic is limited to 720/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The G3X and the LX5 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-LVF1 for the LX5 – are available as accessories. The table below summarizes some of the other core capabilities of the Canon G3 X and Panasonic LX5 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G3X has a touchscreen, while the LX5 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

Both the G3X and the LX5 have zoom lenses built in. The G3X has a 24-600mm f/2.8-5.6 optic and the LX5 offers a 24-90mm f/2.0-3.3 (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 LX5 offers the faster maximum aperture.

Concerning the storage of imaging data, both the G3X and the LX5 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 LX5 cannot take advantage of Ultra High Speed SD cards.

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 G3 X and Panasonic Lumix DMC-LX5 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 LX5. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the G3X and the LX5 have been discontinued, but can regularly be found used on ebay. The LX5 was replaced by the Panasonic LX7, while the G3X does not have a direct successor. Further information on the features and operation of the G3X and LX5 can be found, respectively, in the Canon G3 X Manual (free pdf) or the online Panasonic LX5 Manual.

If the number of relative strengths (bullet points above) is taken as a guide, the G3X is the clear winner of the match-up (20 : 8 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 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 G3 X and the Panasonic LX5 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 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 G3X or the LX5 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.

Expert reviews

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], 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 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.
