Canon S120 vs Olympus E-PM2
The Canon PowerShot S120 and the Olympus PEN E-PM2 are two digital cameras that were officially introduced, respectively, in August 2013 and September 2012. The S120 is a fixed lens compact, while the E-PM2 is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (S120) and a Four Thirds (E-PM2) sensor. The Canon has a resolution of 12 megapixels, whereas the Olympus provides 15.9 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-PM2? 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 Olympus E-PM2 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The E-PM2 can be obtained in four different colors (black, silver, red, 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-PM2 is notably larger (19 percent) than the Canon S120. In this context, it is worth noting that neither the S120 nor the E-PM2 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-PM2 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-PM2 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.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The S120 was launched at a lower price than the E-PM2, 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.
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. 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 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-PM2 a Four Thirds sensor. The sensor area in the E-PM2 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 15.9MP, the E-PM2 offers a higher resolution than the S120 (12MP), but the E-PM2 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 1.89μm for the S120) due to its larger sensor. However, the S120 is a somewhat more recent model (by 11 months) than the E-PM2, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Olympus E-PM2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-PM2 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 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 Olympus PEN E-PM2 are ISO 100 to ISO 25600 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 E-PM2 offers substantially better image quality than the S120 (overall score 16 points higher). The advantage is based on 1.4 bits higher color depth, 0.3 EV in additional dynamic range, and 1.9 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the S120 provides a higher frame rate than the E-PM2. It can shoot video footage at 1080/60p, while the Olympus is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The S120 and the E-PM2 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-PM2 can be equipped with an optional viewfinder – the VF-4. The adjacent table lists some of the other core features of the Canon S120 and Olympus E-PM2 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The S120 has one, while the E-PM2 does not. While the built-in flash of the S120 is not very powerful, it can at times be useful as a fill-in light.
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-PM2 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-PM2 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-PM2 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the S120 and the E-PM2 have been discontinued, but can regularly be found used on eBay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Canon and Olympus. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Olympus websites.
So what conclusions can be drawn? Is the Canon S120 better than the Olympus E-PM2 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Canon PowerShot S120:
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- More detailed LCD: Has a higher resolution rear screen (922k vs 460k dots).
- Faster burst: Shoots at higher frequency (12.1 vs 8 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-PM2 requires a separate lens.
- More compact: Is smaller (100x59mm vs 110x64mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-PM2).
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- 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: Is somewhat more recent (announced 11 months after the E-PM2).
Advantages of the Olympus PEN E-PM2:
- More detail: Has more megapixels (15.9 vs 12MP), which boosts linear resolution by 15%.
- Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).
- Better low-light sensitivity: Can shoot in dim conditions (1.9 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 (360 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 on the market for longer (launched in September 2012).
If the count of relative strengths (bullet points above) is taken as a measure, the S120 comes out slightly ahead of the E-PM2 (11 : 10 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-PM2 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the S120 or the E-PM2. 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 why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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 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.
