Olympus E-M1 vs Panasonic S1

The Olympus OM-D E-M1 and the Panasonic Lumix DC-S1 are two enthusiast cameras that were officially introduced, respectively, in September 2013 and February 2019. Both the E-M1 and the S1 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-M1) 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

An illustration of the physical size and weight of the Olympus E-M1 and the Panasonic S1 is provided in the side-by-side display below. 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 width, height and depth measures are rounded to the nearest millimeter.

The E-M1 can be obtained in two different colors (black, silver), while the S1 is only available in black.

Size Olympus E-M1 vs Panasonic S1
Compare E-M1 versus S1 top
Comparison E-M1 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 notably larger (34 percent) than the Olympus E-M1. Moreover, the S1 is substantially heavier (105 percent) than the E-M1. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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-M1 gets 350 shots out of its Olympus BLN-1 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Any camera decision will obviously take relative prices into account. 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 E-M1 was launched at a markedly lower price (by 44 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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-M1 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-M1 has a native 4:3 aspect ratio, while the one in the S1 offers a 3:2 aspect.

Olympus E-M1 and Panasonic S1 sensor measures

With 24MP, the S1 offers a higher resolution than the E-M1 (15.9MP), but the S1 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.76μm for the E-M1) due to its larger sensor. Moreover, the S1 is a much more recent model (by 5 years and 4 months) than the E-M1, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the 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-M1 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.

The E-M1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the E-M1, 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 OM-D E-M1 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. 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-M1 versus S1 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 consideration, the S1 offers substantially better image quality than the E-M1 (overall score 22 points higher). The advantage is based on 2.2 bits higher color depth, 1.8 EV in additional dynamic range, and 2.1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

One feature that is present on the S1, but is missing on the E-M1 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, both cameras under consideration feature an 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 Olympus E-M1 and the Panasonic S1 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.

The E-M1 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-M1 only has one slot. The S1 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the E-M1 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 OM-D E-M1 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 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The E-M1 lacks such a headphone port.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

The S1 is a recent model that features in the current product line-up of Panasonic. In contrast, the E-M1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M1 was succeeded by the Olympus E-M1 II. Further information on the features and operation of the E-M1 and S1 can be found, respectively, in the Olympus E-M1 Manual (free pdf) or the online Panasonic S1 Manual.

Review summary

So what conclusions can be drawn? Is the Olympus E-M1 better than the Panasonic S1 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Olympus OM-D E-M1:

  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More compact: Is smaller (130x94mm vs 149x110mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 520g or 51 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (44 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2013).

ilogo

Reasons to prefer the Panasonic Lumix DC-S1:

  • More detail: Has more megapixels (24 vs 15.9MP), which boosts linear resolution by 25%.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better image quality: Scores substantially higher (22 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.8 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.1 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/60p vs 1080/30p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 2360k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.74x).
  • 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 1037k dots).
  • More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
  • Longer lasting: Gets more shots (400 versus 350) out of a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • 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 5 years and 4 months of technical progress since the E-M1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the S1 is the clear winner of the contest (22 : 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-M1 05:22 S1

How about other alternatives? Do the specifications of the Olympus E-M1 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 remains incomplete and does no justice, for example, to the way the E-M1 or the S1 perform in practice. 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 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 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 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.
