Canon S120 vs Olympus E-P3
The Canon PowerShot S120 and the Olympus PEN E-P3 are two digital cameras that were revealed to the public, respectively, in August 2013 and June 2011. The S120 is a fixed lens compact, while the E-P3 is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (S120) and a Four Thirds (E-P3) sensor. The Canon has a resolution of 12 megapixels, whereas the Olympus provides 12.2 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 Olympus PEN E-P3? 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 physical size and weight of the Canon S120 and the Olympus E-P3 are illustrated 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 size dimensions are rounded to the nearest millimeter.
The E-P3 can be obtained in three different colors (black, silver, white), 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 Olympus E-P3 is considerably larger (43 percent) than the Canon S120. In this context, it is worth noting that neither the S120 nor the E-P3 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 E-P3 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 E-P3 and their specifications in the Micro Four Thirds Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 E-P3, 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 Olympus E-P3 a Four Thirds sensor. The sensor area in the E-P3 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 12.2MP, the E-P3 offers a higher resolution than the S120 (12MP), but the E-P3 nevertheless has larger individual pixels (pixel pitch of 4.29μm versus 1.89μm for the S120) due to its larger sensor. However, the S120 is a much more recent model (by 2 years and 1 month) than the E-P3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The Canon PowerShot S120 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Olympus PEN E-P3 are ISO 200 to ISO 12800 (no boost).
In terms of underlying technology, the S120 is build around a BSI-CMOS sensor, while the E-P3 uses a CMOS 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.
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 review, the S120 has a notably higher overall DXO score than the E-P3 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.5 bits higher color depth, 1.8 EV in additional dynamic range, and 1.1 stops of reduced 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 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 S120 provides a higher frame rate than the E-P3. It can shoot video footage at 1080/60p, while the Olympus is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. The S120 and the E-P3 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 E-P3 can be equipped with an optional viewfinder – the VF-3. The adjacent table lists some of the other core features of the Canon S120 and Olympus E-P3 along with similar information for a selection of comparators.

The Canon S120 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 S120 and the E-P3 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 Olympus PEN E-P3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S120 offers wifi support, while the E-P3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the S120 and the E-P3 have been discontinued, but can regularly be found used on ebay. The E-P3 was replaced by the Olympus E-P5, while the S120 does not have a direct successor. Further information on the features and operation of the S120 and E-P3 can be found, respectively, in the Canon S120 Manual (free pdf) or the online Olympus E-P3 Manual.
So how do things add up? Which of the two cameras – the Canon S120 or the Olympus E-P3 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Advantages of the Canon PowerShot S120:
- Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1.8 EV of extra DR).
- Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
- More detailed LCD: Has a higher resolution rear screen (922k vs 614k dots).
- Faster burst: Shoots at higher frequency (12.1 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Has a lens built-in, whereas the E-P3 requires a separate lens.
- More compact: Is smaller (100x59mm vs 122x69mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-P3).
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 2 years and 1 month of technical progress since the E-P3 launch.
Arguments in favor of the Olympus PEN E-P3:
- Better low-light sensitivity: Can shoot in dim conditions (1.1 stops ISO advantage).
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (330 versus 230) 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 June 2011).
If the count of relative strengths (bullet points above) is taken as a measure, the S120 is the clear winner of the match-up (12 : 7 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 S120 and the Olympus E-P3 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 says little about, for example, the shooting experience and imaging performance of the S120 and the E-P3 in practical situations. 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 expert reviews are important. 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
