Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony RX100 III and the Olympus E-M10 III. 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-M10 III can be obtained in two different colors (black, silver), while the RX100 III is only available in black.

Compare RX100 III versus E-M10 III top
Comparison RX100 III or E-M10 III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 III is considerably larger (73 percent) than the Sony RX100 III. In this context, it is worth noting that neither the RX100 III nor the E-M10 III are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 III has a lens built in, whereas the E-M10 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-M10 III and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the RX100 III gets 320 shots out of its Sony NP-BX1 battery, while the E-M10 III can take 330 images on a single charge of its Olympus BLS-50 power pack. The power pack in the RX100 III can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony RX100 III features an one-inch sensor and the Olympus E-M10 III a Four Thirds sensor. The sensor area in the E-M10 III is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the RX100 III has a native 3:2 aspect ratio, while the one in the E-M10 III offers a 4:3 aspect.

Sony RX100 III and Olympus E-M10 III sensor measures

Despite having a smaller sensor, the Sony RX100 III offers a higher resolution of 20 megapixels, compared with 15.9 MP of the Olympus E-M10 III. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 3.76μm for the E-M10 III). Moreover, it should be noted that the E-M10 III is much more recent (by 3 years and 3 months) than the RX100 III, 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 the E-M10 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony RX100 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 III for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Olympus E-M10 III are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

The Sony Cyber-shot DSC-RX100 III has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Olympus OM-D E-M10 Mark III are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the RX100 III is build around a BSI-CMOS sensor, while the E-M10 III uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M10 III has a touchscreen, while the RX100 III has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The RX100 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 E-M10 III 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-M10 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-M10 III 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 RX100 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the E-M10 III uses SDXC cards. The E-M10 III supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the RX100 III can use UHS-I cards (up to 104 MB/s).

It is notable that the E-M10 III has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The RX100 III does not feature such an accessory-socket.

Both the RX100 III and the E-M10 III have been discontinued, but can regularly be found used on ebay. The RX100 III was replaced by the Sony RX100 IV, while the E-M10 III was followed by the Olympus E-M10 IV. Further information on the features and operation of the RX100 III and E-M10 III can be found, respectively, in the Sony RX100 III Manual (free pdf) or the online Olympus E-M10 III Manual.

Review summary

So how do things add up? Is the Sony RX100 III better than the Olympus E-M10 III or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Sony Cyber-shot DSC-RX100 III:

  • More detail: Offers more megapixels (20 vs 15.9MP) with a 14% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (10 vs 8.6 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has a lens built-in, whereas the E-M10 III requires a separate lens.
  • More compact: Is smaller (102x58mm vs 122x84mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-M10 III).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been available for much longer (launched in May 2014).

ilogo

Arguments in favor of the Olympus OM-D E-M10 Mark III:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • 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 definition movie capture (4K/30p vs 1080/60p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.62x vs 0.59x).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 3 years and 3 months of technical progress since the RX100 III launch.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M10 III is the clear winner of the contest (16 : 11 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 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.

RX100 III 11:16 E-M10 III

How about other alternatives? Do the specifications of the Sony RX100 III and the Olympus E-M10 III place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens Camera listings 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 remains incomplete and does no justice, for example, to the way the RX100 III or the E-M10 III perform in practice. 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 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.

padding

The above review scores should be interpreted 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
