Canon S120 vs Panasonic GX7
The Canon PowerShot S120 and the Panasonic Lumix DMC-GX7 are two digital cameras that were revealed to the public in August 2013. The S120 is a fixed lens compact, while the GX7 is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (S120) and a Four Thirds (GX7) sensor. The Canon has a resolution of 12 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 S120 and the Panasonic Lumix DMC-GX7? 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 S120 and the Panasonic GX7 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 width, height and depth dimensions are rounded to the nearest millimeter.
The GX7 can be obtained in two different colors (black, silver), while the S120 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 GX7 is considerably larger (48 percent) than the Canon S120. In this context, it is worth noting that neither the S120 nor the GX7 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the S120 has a lens built in, whereas the GX7 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 GX7 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 S120 was launched at a lower price than the GX7, despite having a lens built in. 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. 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 S120 features a 1/1.7-inch sensor and the Panasonic GX7 a Four Thirds sensor. The sensor area in the GX7 is 423 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
With 15.8MP, the GX7 offers a higher resolution than the S120 (12MP), but the GX7 nevertheless has larger individual pixels (pixel pitch of 3.77μm versus 1.89μm for the S120) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.
The resolution advantage of the Panasonic GX7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX7 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Canon S120 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 S120 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-GX7 are ISO 125 to ISO 25600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 consideration, the GX7 offers substantially better image quality than the S120 (overall score 14 points higher). The advantage is based on 1.3 bits higher color depth, 0.3 EV in additional dynamic range, and 1.5 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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, and both provide the same movie specifications (1080/60p).
Beyond body and sensor, cameras can and do differ across a range of features. For example, the GX7 has an electronic viewfinder (2760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the S120 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 S120, the Panasonic GX7, and comparable cameras.

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 GX7 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 Canon S120 and the Panasonic GX7 both have 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 S120 and the GX7 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.
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 S120 and Panasonic Lumix DMC-GX7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX7 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The S120 does not feature such an accessory-socket.
Both the S120 and the GX7 have been discontinued, but can regularly be found used on eBay. The GX7 was replaced by the Panasonic GX85, while the S120 does not have a direct successor. 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 S120 better than the Panasonic GX7 or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon PowerShot S120:
- Faster burst: Shoots at higher frequency (12.1 vs 5 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has a lens built-in, whereas the GX7 requires a separate lens.
- More compact: Is smaller (100x59mm vs 123x71mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the GX7).
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
Arguments in favor of the Panasonic Lumix DMC-GX7:
- More detail: Has more megapixels (15.8 vs 12MP), which boosts linear resolution by 15%.
- Better image quality: Scores substantially higher (14 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
- Better low-light sensitivity: Can shoot in dim conditions (1.5 stops ISO advantage).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (350 versus 230) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
If the count of relative strengths (bullet points above) is taken as a measure, the GX7 is the clear winner of the contest (13 : 5 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.
How about other alternatives? Do the specifications of the Canon S120 and the Panasonic GX7 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 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 S120 or the GX7 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.
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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
