Olympus E-PM2 vs Panasonic S1

The Olympus PEN E-PM2 and the Panasonic Lumix DC-S1 are two digital cameras that were announced, respectively, in September 2012 and February 2019. Both the E-PM2 and the S1 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-PM2) and a full frame (S1) sensor. The Olympus has a resolution of 15.9 megapixels, whereas the Panasonic provides 24 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Olympus E-PM2 and the Panasonic S1. 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 E-PM2 can be obtained in four different colors (black, silver, red, white), while the S1 is only available in black.

Compare E-PM2 versus S1 top
Comparison E-PM2 or S1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1 is considerably larger (133 percent) than the Olympus E-PM2. Moreover, the S1 is substantially heavier (278 percent) than the E-PM2. It is noteworthy in this context that the S1 is splash and dust-proof, while the E-PM2 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the E-PM2 gets 360 shots out of its Olympus BLS-5 battery, while the S1 can take 400 images on a single charge of its Panasonic DMW-BLJ31 power pack. The power pack in the S1 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 E-PM2 was launched at a markedly lower price (by 80 percent) than the S1, which puts it into a different market segment. 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.

Sensor comparison

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. 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 Olympus E-PM2 features a Four Thirds sensor and the Panasonic S1 a full frame sensor. The sensor area in the S1 is 276 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-PM2 has a native 4:3 aspect ratio, while the one in the S1 offers a 3:2 aspect.

Olympus E-PM2 and Panasonic S1 sensor measures

With 24MP, the S1 offers a higher resolution than the E-PM2 (15.9MP), but the S1 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.76μm for the E-PM2) due to its larger sensor. Moreover, the S1 is a much more recent model (by 6 years and 4 months) than the E-PM2, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the S1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic S1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S1 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus E-PM2 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

Unlike the E-PM2, the S1 has the capacity to capture high quality composite images (96MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Olympus PEN E-PM2 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Panasonic Lumix DC-S1 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

E-PM2 versus S1 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 S1 offers substantially better image quality than the E-PM2 (overall score 23 points higher). The advantage is based on 2.5 bits higher color depth, 2.3 EV in additional dynamic range, and 1.8 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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 S1 provides a better video resolution than the E-PM2. It can shoot movie footage at 4K/60p, while the Olympus is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the S1 has an electronic viewfinder (5760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-PM2 relies on live view and the rear LCD for framing. 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 Olympus E-PM2 and Panasonic S1 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the S1, but is missing on the E-PM2 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

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 S1 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 Panasonic S1 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.

The E-PM2 writes its imaging data to SDXC cards, while the S1 uses SDXC or XQD cards. The S1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-PM2 only has one slot. The S1 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the E-PM2 can use UHS-I cards (up to 104 MB/s).

Connectivity comparison

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 Olympus PEN E-PM2 and Panasonic Lumix DC-S1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-PM2 does not provide wifi capability.

Studio photographers will appreciate that the Panasonic S1 (unlike the E-PM2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The S1 is a recent model that features in the current product line-up of Panasonic. In contrast, the E-PM2 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the E-PM2 from Olympus. Further information on the features and operation of the E-PM2 and S1 can be found, respectively, in the Olympus E-PM2 Manual (free pdf) or the online Panasonic S1 Manual.

Review summary

So what is the bottom line? Is the Olympus E-PM2 better than the Panasonic S1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Olympus PEN E-PM2:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (110x64mm vs 149x110mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 748g or 74 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (80 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2012).

ilogo

Arguments in favor of the Panasonic Lumix DC-S1:

  • More detail: Has more megapixels (24 vs 15.9MP), which boosts linear resolution by 25%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better image quality: Scores substantially higher (23 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.5 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.3 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.8 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/60p vs 1080/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2100k vs 460k dots).
  • More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (9 vs 8 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (400 versus 360) out of a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 6 years and 4 months of technical progress since the E-PM2 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the S1 is the clear winner of the contest (30 : 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.

E-PM2 05:30 S1

How about other alternatives? Do the specifications of the Olympus E-PM2 and the Panasonic S1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 E-PM2 and the S1 in practical situations. 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.

Expert reviews

This is why hands-on reviews by experts 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
