Olympus E-M10 III versus Sony RX100 V
The Olympus OM-D E-M10 Mark III and the Sony Cyber-shot DSC-RX100 V are two digital cameras that were officially introduced, respectively, in August 2017 and October 2016. The E-M10 III is a mirrorless interchangeable lens camera, while the RX100 V is a fixed lens compact. The cameras are based on a Four Thirds (E-M10 III) and an one-inch (RX100 V) sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Sony provides 20 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.
Body comparison: Olympus E-M10 III vs Sony RX100 V
The physical size and weight of the Olympus E-M10 III and the Sony RX100 V are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the E-M10 III – represents the basis or 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 V is considerably smaller (42 percent) than the Olympus E-M10 III. In this context, it is worth noting that neither the E-M10 III nor the RX100 V are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 V has a lens build 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 find an overview of optics for the E-M10 III and their specifications in the Micro Four Thirds Lens Catalog.
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, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also 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. 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.
Sensor comparison: Olympus E-M10 III vs Sony RX100 V
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 tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 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-M10 III features a Four Thirds sensor and the Sony RX100 V an one-inch sensor. The sensor area in the RX100 V is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the E-M10 III has a native 4:3 aspect ratio, while the one in the RX100 V offers a 3:2 aspect.
Despite having a smaller sensor, the RX100 V offers a higher resolution of 20 megapixel, compared with 15.9 MP of the E-M10 III. This megapixel 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 a somewhat more recent model (by 10 months) than the RX100 V, and its sensor might 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 the E-M10 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
For most cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Review summary: Olympus E-M10 III vs Sony RX100 V
So what is the bottom line? Is there a clear favorite between the Olympus E-M10 III and the Sony RX100 V? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer 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: Features a larger and more technologically advanced imaging sensor.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- Longer lasting: Can take more shots (330 versus 220) on a single battery charge.
- More modern: Is somewhat more recent (announced 10 months after the RX100 V).
Arguments in favor of the Sony Cyber-shot DSC-RX100 V:
- More detail: Has more megapixels (20 vs 15.9MP), which boosts linear resolution by 14%.
- 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).
- Faster burst: Shoots at higher frequency (24 vs 8.6 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has an integrated lens, whereas the E-M10 III necessitates an extra lens.
- More compact: Is smaller (102x58mm vs 122x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens build in (unlike the E-M10 III).
- More heavily discounted: Has been on the market for longer (launched in October 2016).
If the count of relative strengths (bullet points above) is taken as a measure, the RX100 V comes out slightly ahead of the E-M10 III (8 : 7 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the E-M10 III or the RX100 V. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
