Canon G9 X vs Panasonic G3
The Canon PowerShot G9 X and the Panasonic Lumix DMC-G3 are two digital cameras that were officially introduced, respectively, in October 2015 and May 2011. The G9X is a fixed lens compact, while the G3 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (G9X) and a Four Thirds (G3) sensor. The Canon has a resolution of 20 megapixels, whereas the Panasonic provides 15.8 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 G9 X and the Panasonic Lumix DMC-G3? 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 side-by-side display below illustrates the physical size and weight of the Canon G9 X and the Panasonic G3. 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 G9X can be obtained in two different colors (black, silver), while the G3 is available in four color-versions (black, brown, red, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G3 is considerably larger (70 percent) than the Canon G9 X. In this context, it is worth noting that neither the G9X nor the G3 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X has a lens built in, whereas the G3 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 G3 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the G9X gets 220 shots out of its NB-13L battery, while the G3 can take 270 images on a single charge of its DMW-BLD10 power pack. The power pack in the G9X can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 G9X was launched at a lower price than the G3, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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 G9 X features an one-inch sensor and the Panasonic G3 a Four Thirds sensor. The sensor area in the G3 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 G9X has a native 3:2 aspect ratio, while the one in the G3 offers a 4:3 aspect.
Despite having a smaller sensor, the Canon G9 X offers a higher resolution of 20 megapixels, compared with 15.8 MP of the Panasonic G3. 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 G3). However, it should be noted that the G9X is much more recent (by 4 years and 5 months) than the G3, 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 G9 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G9X 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 G3 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.
The Canon PowerShot G9 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-G3 are ISO 160 to ISO 6400 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the G9X has a notably higher overall DXO score than the G3 (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.5 bits higher color depth, 1.7 EV in additional dynamic range, and 0.4 stops of reduced 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 are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G9X provides a higher frame rate than the G3. It can shoot video footage at 1080/60p, while the Panasonic is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G3 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G9X relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon G9 X, the Panasonic G3, and comparable cameras.

The Canon G9 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 G9X and the G3 write their files to SDXC cards. The G9X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G3 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 G9 X and Panasonic Lumix DMC-G3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G9X offers wifi support, while the G3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the G9X and the G3 have been discontinued, but can regularly be found used on eBay. The G3 was replaced by the Panasonic G5, while the G9X was followed by the Canon G9 X Mark II. 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 how do things add up? Is the Canon G9 X better than the Panasonic G3 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon PowerShot G9 X:
- More detail: Offers more megapixels (20 vs 15.8MP) with a 15% higher linear resolution.
- Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.

- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (270 versus 220) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been around for much longer (launched in May 2011).
If the count of relative strengths (bullet points above) is taken as a measure, the G9X is the clear winner of the match-up (17 : 9 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 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 G9 X and the Panasonic G3 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G9X or the G3. 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 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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
