Olympus E-M1X vs Panasonic S1R

The Olympus OM-D E-M1X and the Panasonic Lumix DC-S1R are two enthusiast cameras that were officially introduced, respectively, in January 2019 and February 2019. Both the E-M1X and the S1R are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-M1X) and a full frame (S1R) sensor. The Olympus has a resolution of 20.2 megapixels, whereas the Panasonic provides 46.7 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 Olympus OM-D E-M1X and the Panasonic Lumix DC-S1R? 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.

Body comparison

The physical size and weight of the Olympus E-M1X and the Panasonic S1R 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 width, height and depth dimensions are rounded to the nearest millimeter.

The E-M1X can be obtained in two different colors (black, silver), while the S1R is only available in black.

Compare E-M1X versus S1R top
Comparison E-M1X or S1R rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1R is notably smaller (23 percent) than the Olympus E-M1X. However, the S1R is slightly heavier (2 percent) than the E-M1X. 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-M1X gets 870 shots out of its BLH-1 battery, while the S1R can take 380 images on a single charge of its DMW-BLJ31 power pack. As can be seen in the images above, the E-M1X has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the S1R, Panasonic provides the DMW-BGS1 vertical grip as an optional accessory (see here on eBay). The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

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

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 E-M1X was launched at a somewhat lower price (by 19 percent) than the S1R, which makes it more attractive for photographers on a tight budget. 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 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-M1X features a Four Thirds sensor and the Panasonic S1R a full frame sensor. The sensor area in the S1R is 284 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-M1X has a native 4:3 aspect ratio, while the one in the S1R offers a 3:2 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Olympus E-M1X and Panasonic S1R sensor measures

With 46.7MP, the S1R offers a higher resolution than the E-M1X (20.2MP), but the S1R nevertheless has larger individual pixels (pixel pitch of 4.30μm versus 3.34μm for the E-M1X) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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 S1R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S1R for good quality output (200 dots per inch) amounts to 41.8 x 27.9 inch or 106.3 x 70.9 cm, for very good quality (250 dpi) 33.5 x 22.3 inch or 85 x 56.7 cm, and for excellent quality (300 dpi) 27.9 x 18.6 inch or 70.8 x 47.3 cm. The corresponding values for the Olympus E-M1X are 25.9 x 19.4 inch or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inch or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inch or 43.9 x 32.9 cm for excellent quality prints.

The E-M1X has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Both cameras have the capacity to capture high quality composite images by combining multiple shots after shifting the 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-M1X has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 64-25600. The corresponding ISO settings for the Panasonic Lumix DC-S1R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

E-M1X versus S1R 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the S1R provides a faster frame rate than the E-M1X. It can shoot movie footage at 4K/60p, while the Olympus is limited to 4K/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the S1R offers a substantially higher resolution than the one in the E-M1X (5760k vs 2360k dots).

One feature that is present on the S1R, but is missing on the E-M1X 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 E-M1X has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the S1R does not have a selfie-screen.

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-M1X 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-M1X writes its imaging data to SDXC cards, while the S1R uses SDHC or XQD cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Moreover, both the E-M1X and the S1R support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s, on both slots.

 

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-M1X and Panasonic Lumix DC-S1R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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

Travel and landscape photographers will find it useful that the E-M1X has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the E-M1X and the S1R are recent models that are part of the current product line-up. Neither of the two has a direct predecessor, so perhaps they will constitute the origins of new camera lines for Olympus and Panasonic. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Panasonic websites.


Review summary

So what is the bottom line? Which of the two cameras – the Olympus E-M1X or the Panasonic S1R – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Olympus OM-D E-M1X:

  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.83x vs 0.78x).
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (18 vs 9 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (870 versus 380) on a single battery charge.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • More affordable: Was introduced into a lower priced segment (19 percent cheaper at launch).

ilogo

Advantages of the Panasonic Lumix DC-S1R:

  • More detail: Has more megapixels (46.7 vs 20.2MP), which boosts linear resolution by 55%.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 2360k dots).
  • 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 compact: Is smaller (149x110mm vs 144x147mm) and will fit more readily into a bag.
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.

If the count of relative strengths (bullet points above) is taken as a measure, the S1R emerges as the winner of the match-up (12 : 9 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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-M1X 09:12 S1R

How about other alternatives? Do the specifications of the Olympus E-M1X and the Panasonic S1R 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the E-M1X and the S1R 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.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
