Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G3 X and the Panasonic Lumix DMC-GX800? 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: Canon G3 X vs Panasonic GX800

An illustration of the physical size and weight of the Canon G3 X and the Panasonic GX800 is provided 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.

The GX800 can be obtained in three different colors (black, silver, red), while the G3X is only available in black.

Size Canon G3 X vs Panasonic GX800
Compare G3X versus GX800 top
Comparison G3X or GX800 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX800 is notably smaller (27 percent) than the Canon G3 X. It is worth mentioning in this context that the G3X is splash and dust resistant, while the GX800 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G3X has a lens built in, whereas the GX800 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 GX800 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G3X gets 300 shots out of its NB-10L battery, while the GX800 can take 210 images on a single charge of its DMW-BLH7 power pack.

Note: Measurements and pricing do not include easily detachable parts, such as 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. 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.

 

Sensor comparison: Canon G3 X vs Panasonic GX800

The size of the sensor inside a digital camera is one of the key determinants 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. 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 G3 X features an one-inch sensor and the Panasonic GX800 a Four Thirds sensor. The sensor area in the GX800 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 G3X has a native 3:2 aspect ratio, while the one in the GX800 offers a 4:3 aspect.

Canon G3 X and Panasonic GX800 sensor measures

Despite having a smaller sensor, the Canon G3 X offers a higher resolution of 20 megapixels, compared with 15.8 MP of the Panasonic GX800. 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 3.77μm for the GX800). Moreover, it should be noted that the GX800 is a somewhat more recent model (by 1 year and 6 months) than the G3X, 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 GX800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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 inch or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inch or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inch or 46.3 x 30.9 cm. The corresponding values for the Panasonic GX800 are 23 x 17.2 inch or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inch or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inch or 38.9 x 29.2 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-GX800 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

G3X versus GX800 MP

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 consideration, the GX800 has a markedly higher DXO score than the G3X (overall score 10 points higher), which will translate into better image quality. The advantage is based on 1.8 bits higher color depth, 1 EV in additional dynamic range, and 0.2 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GX800 provides a better video resolution than the G3X. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison: Canon G3 X vs Panasonic GX800

Apart from body and sensor, cameras can and do differ across a range of features. The G3X and the GX800 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. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1. The adjacent table lists some of the other core features of the Canon G3 X and Panasonic GX800 along with similar information for a selection of comparators.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

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, the GX800 is one of those camera that have an additional 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 Panasonic GX800 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 G3X and the GX800 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: Canon G3 X vs Panasonic GX800

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.

ilogo

Arguments in favor of the Panasonic Lumix DMC-GX800:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.8 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Faster burst: Shoots at higher frequency (10 vs 5.9 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • More compact: Is smaller (107x65mm vs 123x77mm) and will fit more readily into a bag.
  • More modern: Was introduced somewhat (1 year and 6 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the G3X is the clear winner of the match-up (15 : 11 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 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.

G3X 15:11 GX800

How about other alternatives? Do the specifications of the Canon G3 X and the Panasonic GX800 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G3X or the GX800. 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: Canon G3 X vs Panasonic GX800

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
