Olympus PEN-F versus Sony RX100 IV
The Olympus PEN-F and the Sony Cyber-shot DSC-RX100 IV are two digital cameras that were officially introduced, respectively, in January 2016 and June 2015. The PEN-F is a mirrorless interchangeable lens camera, while the RX100 IV is a fixed lens compact. The cameras are based on a Four Thirds (PEN-F) and an one-inch sensor. The Olympus has a resolution of 20.2 megapixel, whereas the Sony provides 20 MP.
An illustration of the physical size and weight of the Olympus PEN-F and the Sony RX100 IV is provided in the side-by-side display below. 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 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 PEN-F – 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 IV is notably smaller (34 percent) than the Olympus PEN-F. Cameras that are intended for semi-professional or professional use are sometimes a bit bulkier in order to provide them with the necessary ruggedness. In this context, it is worth noting that neither the PEN-F nor the RX100 IV 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 comparisons there.

The listed 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.
The size of the sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus PEN-F features a Four Thirds sensor and the Sony RX100 IV an one-inch sensor. The sensor area in the RX100 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 PEN-F has a native 4:3 aspect ratio, while the one in the RX100 IV offers a 3:2 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 pixels. 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.
For most cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under review, the PEN-F has a notably higher overall DXO score than the PEN-F (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. 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 better video resolution than the PEN-F. It can shoot movie footage at 4K/30p, while the Olympus is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration 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 table below summarizes some of the other core capabilities of the Olympus PEN-F and Sony RX100 IV in connection with corresponding information for a sample of similar cameras.

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.
So how do things add up? Is the Olympus PEN-F better than the Sony RX100 IV or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Olympus PEN-F:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
- More detailed viewfinder: Has a higher resolution electronic viewfinder (2360k vs 2359k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster shutter: Has a higher mechanical shutter speed (8000/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 280) on a single battery charge.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More modern: Is somewhat more recent (announced 7 months after the RX100 IV).
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 an integrated lens, whereas the PEN-F necessitates an extra lens.
- More compact: Is smaller (102x58mm vs 125x72mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens build in (unlike the PEN-F).
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- 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 January 2016).
If the number of relative strengths (bullet points above) is taken as a guide, the PEN-F comes out slightly ahead of the RX100 IV (11 : 10 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.
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 PEN-F and the RX100 IV 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 expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites.

The above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
