Sony RX100 IV versus Olympus PEN-F
The Sony Cyber-shot DSC-RX100 IV and the Olympus PEN-F are two digital cameras that were announced, respectively, in June 2015 and January 2016. The RX100 IV is a fixed lens compact, while the PEN-F is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (RX100 IV) and a Four Thirds (PEN-F) sensor. The Sony has a resolution of 20 megapixel, whereas the Olympus provides 20.2 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: Sony RX100 IV vs Olympus PEN-F
The side-by-side display below illustrates the physical size and weight of the Sony RX100 IV and the Olympus PEN-F. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button 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 RX100 IV – represents 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 Olympus PEN-F is considerably larger (52 percent) than the Sony RX100 IV. In this context, it is worth noting that neither the RX100 IV nor the PEN-F are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 IV has a lens build in, whereas the PEN-F 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 PEN-F 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. The RX100 IV was launched at a lower price than the PEN-F, despite having a lens build in. 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: Sony RX100 IV vs Olympus PEN-F
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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Sony RX100 IV features an one-inch sensor and the Olympus PEN-F a Four Thirds sensor. The sensor area in the PEN-F 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 IV has a native 3:2 aspect ratio, while the one in the PEN-F offers a 4:3 aspect.
With 20.2MP, the PEN-F offers a higher resolution than the RX100 IV (20MP), but the PEN-F nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the RX100 IV) due to its larger sensor. Moreover, the PEN-F is a somewhat more recent model (by 7 months) than the RX100 IV, and its sensor might 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 PEN-F has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Unlike the RX100 IV, the PEN-F has the capacity to capture high quality composite images (40MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the PEN-F has a markedly higher DXO score than the RX100 IV (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.3 bits higher color depth, 0.2 EV of lower dynamic range, and 0.6 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the RX100 IV provides a higher video resolution than the PEN-F. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/60p.
Feature comparison: Sony RX100 IV vs Olympus PEN-F
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the PEN-F offers a slightly higher resolution than the one in the RX100 IV (2360k vs 2359k dots).

The PEN-F is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX100 IV has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 IV was succeeded by the Sony RX100 V.
Review summary: Sony RX100 IV vs Olympus PEN-F
So what is the bottom line? Is the Sony RX100 IV better than the Olympus PEN-F or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Sony Cyber-shot DSC-RX100 IV:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- More detailed LCD: Has a higher resolution rear screen (1228k vs 1037k dots).
- Faster burst: Shoots at higher frequency (16 vs 10 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has a lens build-in, whereas the PEN-F requires a separate lens.
- More compact: Is smaller (102x58mm vs 125x72mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a build-in lens (unlike the PEN-F).
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced at a lower price, despite coming with a build-in lens.
- More heavily discounted: Has been on the market for longer (launched in June 2015).
Arguments in favor of the Olympus PEN-F:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
- Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (330 versus 280) out of a single battery charge.
- More modern: Was introduced somewhat (7 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (10 points each). 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.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX100 IV and the PEN-F in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
