Olympus E-M1 II vs Panasonic S1R
The Olympus OM-D E-M1 Mark II and the Panasonic Lumix DC-S1R are two enthusiast cameras that were officially introduced, respectively, in September 2016 and February 2019. Both the E-M1 II and the S1R are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-M1 II) 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-M1 Mark II 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.
The side-by-side display below illustrates the physical size and weight of the Olympus E-M1 II and the Panasonic S1R. 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 dimensions are rounded to the nearest millimeter.
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 larger (34 percent) than the Olympus E-M1 II. Moreover, the S1R is substantially heavier (77 percent) than the E-M1 II. 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 II gets 440 shots out of its BLH-1 battery, while the S1R can take 380 images on a single charge of its DMW-BLJ31 power pack. The power pack in the S1R can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will naturally be influenced heavily by the price. 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-M1 II was launched at a markedly lower price (by 46 percent) than the S1R, 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.
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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 II 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-M1 II has a native 4:3 aspect ratio, while the one in the S1R offers a 3:2 aspect.
With 46.7MP, the S1R offers a higher resolution than the E-M1 II (20.2MP), but the S1R nevertheless has larger individual pixels (pixel pitch of 4.30μm versus 3.34μm for the E-M1 II) due to its larger sensor. Moreover, the S1R is a much more recent model (by 2 years and 4 months) than the E-M1 II, 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 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 inches or 106.3 x 70.9 cm, for very good quality (250 dpi) 33.5 x 22.3 inches or 85 x 56.7 cm, and for excellent quality (300 dpi) 27.9 x 18.6 inches or 70.8 x 47.3 cm. The corresponding values for the Olympus E-M1 II are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.
The E-M1 II 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-M1 Mark II 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.
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.
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 S1R offers substantially better image quality than the E-M1 II (overall score 20 points higher). The advantage is based on 2.7 bits higher color depth, 1.3 EV in additional dynamic range, and 1.4 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.

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-M1 II. It can shoot movie footage at 4K/60p, while the Olympus is limited to 4K/30p.
Apart from body and sensor, cameras can and do differ across a range 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-M1 II (5760k vs 2360k dots). The adjacent table lists some of the other core features of the Olympus E-M1 II and Panasonic S1R along with similar information for a selection of comparators.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
One feature that is present on the S1R, but is missing on the E-M1 II 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-M1 II 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-M1 II and the Panasonic S1R 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 II writes its imaging data to SDXC cards, while the S1R uses SDXC or XQD cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. However, while the S1R supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s) on both slots, the E-M1 II supports UHS-II only on its first slot and UHS-I (data transfer speed up to 104 MB/s) on the second one.
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 Mark II 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.
The S1R is a recent model that features in the current product line-up of Panasonic. In contrast, the E-M1 II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M1 II was succeeded by the Olympus E-M1 III. 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.
So what conclusions can be drawn? Is the Olympus E-M1 II better than the Panasonic S1R or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Olympus OM-D E-M1 Mark II:
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- 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.

If the count of individual advantages (bullet points above) is taken as a guide, the S1R is the clear winner of the contest (15 : 8 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Olympus E-M1 II 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 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-M1 II and the S1R 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.
This is why expert reviews 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.

The review scores listed above should be treated 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.
