Canon S120 vs Olympus E-PM1
The Canon PowerShot S120 and the Olympus PEN E-PM1 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-PM1 is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (S120) and a Four Thirds (E-PM1) 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-PM1? 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-PM1 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 size dimensions are rounded to the nearest millimeter.
The E-PM1 can be obtained in six different colors (black, silver, brown, pink, purple, 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-PM1 is notably larger (19 percent) than the Canon S120. In this context, it is worth noting that neither the S120 nor the E-PM1 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-PM1 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-PM1 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.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The S120 was launched at a lower price than the E-PM1, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 tend to be more expensive and 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-PM1 a Four Thirds sensor. The sensor area in the E-PM1 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-PM1 offers a higher resolution than the S120 (12MP), but the E-PM1 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-PM1, 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-PM1 are ISO 100 to ISO 12800 (no boost).
In terms of underlying technology, the S120 is build around a BSI-CMOS sensor, while the E-PM1 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.
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 S120 has a notably higher overall DXO score than the E-PM1 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.3 bits higher color depth, 1.6 EV in additional dynamic range, and 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 can also record movies. 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-PM1. It can shoot video footage at 1080/60p, while the Olympus is limited to 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. The S120 and the E-PM1 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-PM1 can be equipped with an optional viewfinder – the VF-2. The table below summarizes some of the other core capabilities of the Canon S120 and Olympus E-PM1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The S120 has one, while the E-PM1 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-PM1 write their files to SDXC cards. The S120 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-PM1 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 S120 and Olympus PEN E-PM1 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-PM1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the S120 and the E-PM1 have been discontinued, but can regularly be found used on ebay. The E-PM1 was replaced by the Olympus E-PM2, while the S120 does not have a direct successor. Further information on the features and operation of the S120 and E-PM1 can be found, respectively, in the Canon S120 Manual (free pdf) or the online Olympus E-PM1 Manual.
So how do things add up? Is there a clear favorite between the Canon S120 and the Olympus E-PM1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon PowerShot S120:
- Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1.6 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 460k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster burst: Shoots at higher frequency (12.1 vs 5.5 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-PM1 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-PM1).
- 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.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- 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-PM1 launch.
Reasons to prefer the Olympus PEN E-PM1:
- Better low-light sensitivity: Can shoot in dim conditions (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 (15 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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-PM1 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-PM1 in practical situations. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
