Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M10 Mark III and the Sony Cyber-shot DSC-RX100? 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: Olympus E-M10 III vs Sony RX100

An illustration of the physical size and weight of the Olympus E-M10 III and the Sony RX100 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-M10 III can be obtained in two different colors (black, silver), while the RX100 is only available in black.

Comparison E-M10 III or RX100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 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 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 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.

The power pack in the RX100 can be charged via the USB port, which can be very convenient when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. 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

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-M10 III features a Four Thirds sensor and the Sony RX100 an one-inch sensor. The sensor area in the RX100 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 offers a 3:2 aspect.

Olympus E-M10 III and Sony RX100 sensor measures

Despite having a smaller sensor, the RX100 offers a higher resolution of 20 megapixels, compared with 15.9 MP of the 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 5 years and 2 months) than the RX100, 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 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 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inch or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inch or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inch or 46.3 x 30.9 cm. The corresponding values for the Olympus E-M10 III are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 cm for excellent quality prints.

The Olympus OM-D E-M10 Mark III has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

ilogo

Advantages of the Sony Cyber-shot DSC-RX100:

  • 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 (10 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 built in (unlike the E-M10 III).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More heavily discounted: Has been around for much longer (launched in June 2012).

If the number of relative strengths (bullet points above) is taken as a guide, the E-M10 III is the clear winner of the match-up (16 : 8 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 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.

How about other alternatives? Do the specifications of the Olympus E-M10 III and the Sony RX100 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-M10 III or the RX100. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews: Olympus E-M10 III vs Sony RX100

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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
