Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M5 Mark III and the Olympus Stylus 1s? 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 side-by-side display below illustrates the physical size and weight of the Olympus E-M5 III and the Olympus Stylus 1s. 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 Stylus 1s is only available in black.

Comparison E-M5 III or Stylus 1s rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus Stylus 1s is notably smaller (5 percent) than the Olympus E-M5 III. It is worth mentioning in this context that the E-M5 III is splash and dust resistant, while the Stylus 1s does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the Stylus 1s has a lens built in, whereas the E-M5 III is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-M5 III and their specifications in the Micro Four Thirds Lens Catalog.

The power pack in the E-M5 III can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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 Stylus 1s was launched at a lower price than the E-M5 III, despite having a lens built in. 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.

Sensor comparison

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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus E-M5 III features a Four Thirds sensor and the Olympus Stylus 1s a 1/1.7-inch sensor. The sensor area in the Stylus 1s is 81 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 4.5. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

In terms of chip-set technology, the E-M5 III uses a more advanced image processing engine (TruePic VIII) than the Stylus 1s (TruePic VI), with benefits for noise reduction, color accuracy, and processing speed.

Olympus E-M5 III and Olympus Stylus 1s sensor measures

With 20.2MP, the E-M5 III offers a higher resolution than the Stylus 1s (11.8MP), but the E-M5 III nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 1.91μm for the Stylus 1s) due to its larger sensor. Moreover, the E-M5 III is a much more recent model (by 4 years and 6 months) than the Stylus 1s, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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 Olympus E-M5 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M5 III for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Olympus Stylus 1s are 19.8 x 14.9 inches or 50.4 x 37.8 cm for good quality, 15.9 x 11.9 inches or 40.3 x 30.2 cm for very good quality, and 13.2 x 9.9 inches or 33.6 x 25.2 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.

Unlike the Stylus 1s, the E-M5 III has the capacity to capture high quality composite images (80MP) 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-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 Olympus Stylus 1s are ISO 100 to ISO 12800 (no boost).

One difference between the cameras concerns the presence of an on-board flash. The Stylus 1s has one, while the E-M5 III does not. While the built-in flash of the Stylus 1s is not very powerful, it can at times be useful as a fill-in light.

The E-M5 III 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 Stylus 1s 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, the E-M5 III is one of those camera that have an additional 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 Olympus Stylus 1s 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 Stylus 1s write their files to SDXC cards. The E-M5 III supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the Stylus 1s cannot take advantage of Ultra High Speed SD cards.

It is notable that the E-M5 III has a microphone port, which is missing on the Stylus 1s. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the E-M5 III and the Stylus 1s are recent models that are part of the current product line-up. The Stylus 1s replaced the earlier Olympus Stylus 1, while the E-M5 III followed on from the Olympus E-M5 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus website.

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better image quality: Features a larger and more technologically advanced imaging 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 jpgs: Has a more modern image processing engine (TruePic VIII vs TruePic VI).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.68x vs 0.58x).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 7 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards.
  • More modern: Reflects 4 years and 6 months of technical progress since the Stylus 1s launch.


Arguments in favor of the Olympus Stylus 1s:

  • Ready to shoot: Has an integrated lens, whereas the E-M5 III necessitates an extra lens.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the E-M5 III).
  • Longer lasting: Gets more shots (450 versus 310) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been around for much longer (launched in April 2015).

If the count of relative strengths (bullet points above) is taken as a measure, the E-M5 III is the clear winner of the match-up (23 : 6 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-M5 III 23:06 Stylus 1s

How about other alternatives? Do the specifications of the Olympus E-M5 III and the Olympus Stylus 1s place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom Camera listings 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 Stylus 1s 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.

Expert reviews

This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
