Canon G3 X vs Panasonic GF3
The Canon PowerShot G3 X and the Panasonic Lumix DMC-GF3 are two digital cameras that were officially introduced, respectively, in June 2015 and June 2011. The G3X is a fixed lens compact, while the GF3 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (G3X) and a Four Thirds (GF3) sensor. The Canon has a resolution of 20 megapixels, whereas the Panasonic provides 12 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-GF3? 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 GF3 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 size dimensions are rounded to the nearest millimeter.
The GF3 can be obtained in five different colors (black, brown, pink, red, 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 GF3 is notably smaller (24 percent) than the Canon G3 X. It is worth mentioning in this context that the G3X is splash and dust resistant, while the GF3 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 GF3 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 GF3 and their specifications in the Micro Four Thirds Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.
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. 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 more expensive and 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 GF3 a Four Thirds sensor. The sensor area in the GF3 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 GF3 offers a 4:3 aspect.
Despite having a smaller sensor, the Canon G3 X offers a higher resolution of 20 megapixels, compared with 12 MP of the Panasonic GF3. 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 4.33μm for the GF3). However, it should be noted that the G3X is much more recent (by 4 years) than the GF3, 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 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 GF3 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 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-GF3 are ISO 160 to ISO 6400 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under review, the G3X provides substantially higher image quality than the GF3, with an overall score that is 14 points higher. This advantage is based on 0.8 bits higher color depth, 2.3 EV in additional dynamic range, and 0.2 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G3X provides a higher frame rate than the GF3. 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 range of features. The G3X and the GF3 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 table below summarizes some of the other core capabilities of the Canon G3 X and Panasonic GF3 in connection with corresponding information for a sample of similar cameras.

Concerning the storage of imaging data, both the G3X and the GF3 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 GF3 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-GF3 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 hotshoe, while the GF3 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
The G3X is a recent model that features in the current product line-up of Canon. In contrast, the GF3 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the GF3 was succeeded by the Panasonic GF5. 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? Is there a clear favorite between the Canon G3 X and the Panasonic GF3? Which camera is better? The listing below highlights the relative strengths of the two models.

- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- More compact: Is smaller (108x67mm vs 123x77mm) and will fit more readily into a bag.
- More heavily discounted: Has been around for much longer (launched in June 2011).
If the count of individual advantages (bullet points above) is taken as a guide, the G3X is the clear winner of the match-up (20 : 4 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 GF3 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 incomplete and does no justice, for example, to the way the G3X or the GF3 perform in practice. 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 adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
