Olympus E-M5 III vs Panasonic S5
The Olympus OM-D E-M5 Mark III and the Panasonic Lumix DC-S5 are two enthusiast cameras that were officially introduced, respectively, in October 2019 and September 2020. Both the E-M5 III and the S5 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-M5 III) 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-M5 Mark III 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.
An illustration of the physical size and weight of the Olympus E-M5 III and the Panasonic S5 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 dimensions are rounded to the nearest millimeter.
The E-M5 III 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 notably larger (23 percent) than the Olympus E-M5 III. Moreover, the S5 is substantially heavier (72 percent) than the E-M5 III. 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-M5 III gets 310 shots out of its BLS-50 battery, while the S5 can take 440 images on a single charge of its DMW-BLK22 power pack. The battery packs of both cameras can be charged via USB, 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-M5 III was launched at a markedly lower price (by 40 percent) than the S5, 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-M5 III 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-M5 III has a native 4:3 aspect ratio, while the one in the S5 offers a 3:2 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 24MP, the S5 offers a higher resolution than the E-M5 III (20.2MP), but the S5 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.34μm for the E-M5 III) due to its larger sensor. Moreover, the S5 is a somewhat more recent model (by 10 months) than the E-M5 III, 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-M5 III 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-M5 III 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-M5 Mark III 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.
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"). 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 S5 provides a faster frame rate than the E-M5 III. 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 E-M5 III 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 adjacent table lists some of the other core features of the Olympus E-M5 III and Panasonic S5 along with similar information for a selection of comparators.

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-M5 III 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-M5 III and the S5 write their files to SDXC cards. The S5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M5 III only has one slot. Both the E-M5 III and the S5 support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s (the second slot of the S5 only offers slower UHS-I transfer rates, though).
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-M5 Mark III and Panasonic Lumix DC-S5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S5 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The E-M5 III lacks such a headphone port.
Both the E-M5 III and the S5 are recent models that are part of the current product line-up. The E-M5 III replaced the earlier Olympus E-M5 II, while the S5 does not have a direct predecessor. 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-M5 III better than the Panasonic S5 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-M5 Mark III:
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Faster burst: Shoots at higher frequency (10 vs 7 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (125x85mm vs 133x98mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 300g or 42 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in October 2019).
Advantages of the Panasonic Lumix DC-S5:
- More detail: Has more megapixels (24 vs 20.2MP), which boosts linear resolution by 11%.
- Better image quality: Is equipped with a larger and more technologically advanced sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.68x).
- More detailed LCD: Has a higher resolution rear screen (1840k vs 1040k dots).
- Longer lasting: Gets more shots (440 versus 310) out of a single battery charge.
- Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More modern: Was introduced somewhat (10 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the S5 is the clear winner of the contest (13 : 6 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-M5 III 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-M5 III and the S5 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], 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
