Olympus E-M1X vs Panasonic S5
The Olympus OM-D E-M1X and the Panasonic Lumix DC-S5 are two enthusiast cameras that were announced, respectively, in January 2019 and September 2020. Both the E-M1X and the S5 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-M1X) and a full frame (S5) sensor. The Olympus has a resolution of 20.2 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.
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-S5? 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-M1X and the Panasonic S5. 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-M1X can be obtained in two different colors (black, silver), while the S5 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 Panasonic S5 is considerably smaller (38 percent) than the Olympus E-M1X. Moreover, the S5 is markedly lighter (28 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 S5 can take 440 images on a single charge of its DMW-BLK22 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 S5, Panasonic provides the DMW-BGS5 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.
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 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 S5 was launched at a markedly lower price (by 33 percent) than the E-M1X, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Olympus E-M1X features a Four Thirds sensor and the Panasonic S5 a full frame sensor. The sensor area in the S5 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-M1X has a native 4:3 aspect ratio, while the one in the S5 offers a 3:2 aspect.
With 24MP, the S5 offers a higher resolution than the E-M1X (20.2MP), but the S5 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.34μm for the E-M1X) due to its larger sensor. Moreover, the S5 is a somewhat more recent model (by 1 year and 7 months) than the E-M1X, and its sensor might 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 S5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S5 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-M1X 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-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-S5 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). 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 can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the S5 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.
Apart from body and sensor, cameras can and do differ across a variety of features. The E-M1X and the S5 are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2360k dots. The table below summarizes some of the other core capabilities of the Olympus E-M1X and Panasonic S5 in connection with corresponding information for a sample of similar cameras.

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 and the Panasonic S5 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.
Concerning the storage of imaging data, both the E-M1X and the S5 write their files to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. However, while the E-M1X supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s) on both slots, the S5 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-M1X and Panasonic Lumix DC-S5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Olympus E-M1X (unlike the S5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
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 S5 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.
So what is the bottom line? Is there a clear favorite between the Olympus E-M1X and the Panasonic S5? Which camera is better? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Olympus OM-D E-M1X:

If the number of relative strengths (bullet points above) is taken as a guide, the S5 emerges as the winner of the match-up (11 : 8 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.
How about other alternatives? Do the specifications of the Olympus E-M1X and the Panasonic S5 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-M1X and the S5 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 why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
