Olympus E-M10 II vs Sony RX10 IV
The Olympus OM-D E-M10 Mark II and the Sony Cyber-shot DSC-RX10 IV are two digital cameras that were revealed to the public, respectively, in August 2015 and September 2017. The E-M10 II is a mirrorless interchangeable lens camera, while the RX10 IV is a fixed lens compact. The cameras are based on a Four Thirds (E-M10 II) and an one-inch (RX10 IV) sensor. The Olympus has a resolution of 15.9 megapixels, whereas the Sony provides 20 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M10 Mark II and the Sony Cyber-shot DSC-RX10 IV? 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.
The physical size and weight of the Olympus E-M10 II and the Sony RX10 IV are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The E-M10 II can be obtained in three different colors (black, silver, brown), while the RX10 IV is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX10 IV is notably larger (26 percent) than the Olympus E-M10 II. It is noteworthy in this context that the RX10 IV is splash and dust-proof, while the E-M10 II does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX10 IV has a lens built in, whereas the E-M10 II 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 II and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the E-M10 II gets 320 shots out of its BLS-50 battery, while the RX10 IV can take 400 images on a single charge of its NP-FW50 power pack. The power pack in the RX10 IV can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.
The size of the imaging sensor is a crucial determinant 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 II features a Four Thirds sensor and the Sony RX10 IV an one-inch sensor. The sensor area in the RX10 IV 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 II has a native 4:3 aspect ratio, while the one in the RX10 IV offers a 3:2 aspect.
Despite having a smaller sensor, the RX10 IV offers a higher resolution of 20 megapixels, compared with 15.9 MP of the E-M10 II. 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 II). However, it should be noted that the RX10 IV is much more recent (by 2 years) than the E-M10 II, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the E-M10 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony RX10 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX10 IV 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 II 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 RX10 IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Olympus OM-D E-M10 Mark II 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-RX10 IV are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 64-25600.
In terms of underlying technology, the E-M10 II is build around a CMOS sensor, while the RX10 IV uses a BSI-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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the RX10 IV provides a better video resolution than the E-M10 II. It can shoot movie footage at 4K/30p, while the Olympus is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the E-M10 II offers a slightly higher resolution than the one in the RX10 IV (2360k vs 2359k dots). The following table reports on some other key feature differences and similarities of the Olympus E-M10 II, the Sony RX10 IV, and comparable cameras.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
One feature that is present on the RX10 IV, but is missing on the E-M10 II is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
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 II 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 II writes its imaging data to SDXC cards, while the RX10 IV uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Olympus OM-D E-M10 Mark II and Sony Cyber-shot DSC-RX10 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX10 IV has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The E-M10 II does not feature such a mic input.
The RX10 IV is a recent model that features in the current product line-up of Sony. In contrast, the E-M10 II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M10 II was succeeded by the Olympus E-M10 III. Further information on the features and operation of the E-M10 II and RX10 IV can be found, respectively, in the Olympus E-M10 II Manual (free pdf) or the online Sony RX10 IV Manual.
So what conclusions can be drawn? Is there a clear favorite between the Olympus E-M10 II and the Sony RX10 IV? Which camera is better? The listing below highlights the relative strengths of the two models.

If the count of individual advantages (bullet points above) is taken as a guide, the RX10 IV is the clear winner of the contest (16 : 10 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 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 II and the Sony RX10 IV 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 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 II or the RX10 IV. 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 why hands-on reviews by experts are important. 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.

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.
