Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M10 Mark IV and the Sony Cyber-shot DSC-RX0? 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 physical size and weight of the Olympus E-M10 IV and the Sony RX0 are illustrated 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 size dimensions are rounded to the nearest millimeter.

The E-M10 IV can be obtained in two different colors (black, silver), while the RX0 is only available in black.

Compare E-M10 IV versus RX0 top
Comparison E-M10 IV or RX0 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX0 is considerably smaller (76 percent) than the Olympus E-M10 IV. It is noteworthy in this context that the RX0 is splash and dust-proof, while the E-M10 IV does not feature any corresponding weather-sealing. More than that, the RX0 is water-proof up to 10m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX0 has a lens built in, whereas the E-M10 IV 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 IV and their specifications in the Micro Four Thirds Lens Catalog.

The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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

Any camera decision will naturally be influenced heavily by the price. 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. 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.

Sensor comparison

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 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 Olympus E-M10 IV features a Four Thirds sensor and the Sony RX0 an one-inch sensor. The sensor area in the RX0 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 IV has a native 4:3 aspect ratio, while the one in the RX0 offers a 3:2 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Olympus E-M10 IV and Sony RX0 sensor measures

With 20.2MP, the E-M10 IV offers a higher resolution than the RX0 (15.4MP), but the E-M10 IV nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.74μm for the RX0) due to its larger sensor. Moreover, the E-M10 IV is a much more recent model (by 2 years and 11 months) than the RX0, 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 IV has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Olympus E-M10 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M10 IV 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 Sony RX0 are 24 x 16 inches or 61 x 40.6 cm for good quality, 19.2 x 12.8 inches or 48.8 x 32.5 cm for very good quality, and 16 x 10.7 inches or 40.6 x 27.1 cm for excellent quality prints.

The Olympus OM-D E-M10 Mark IV 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-RX0 are ISO 125 to ISO 12800 (no boost).

E-M10 IV versus RX0 MP

One difference between the cameras concerns the presence of an on-board flash. The E-M10 IV has one, while the RX0 does not. While the built-in flash of the E-M10 IV is not very powerful, it can at times be useful as a fill-in light.

The E-M10 IV 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 RX0 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, 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-M10 IV 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 E-M10 IV writes its imaging data to SDXC cards, while the RX0 uses micro SDXC or Memory Stick Micro cards. The E-M10 IV supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the RX0 can use UHS-I cards (up to 104 MB/s).

ilogo

Reasons to prefer the Sony Cyber-shot DSC-RX0:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Ready to shoot: Has an integrated lens, whereas the E-M10 IV necessitates an extra lens.
  • More compact: Is smaller (59x41mm 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 IV).
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
  • More heavily discounted: Has been around for much longer (launched in August 2017).

If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 IV is the clear winner of the match-up (22 : 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 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.

E-M10 IV 22:08 RX0

How about other alternatives? Do the specifications of the Olympus E-M10 IV and the Sony RX0 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-M10 IV or the RX0. 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

This is why expert reviews are important. 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 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.
