Going beyond this snapshot of core features and characteristics, what are the differences between the Pentax WG-90 and the Sony Cyber-shot DSC-RX1R III? 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 Pentax WG-90 and the Sony RX1R III 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 size dimensions are rounded to the nearest millimeter.
The WG-90 can be obtained in two different colors (black, blue), while the RX1R III 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 Pentax WG-90 and the Sony RX1R III are of equal size. However, the RX1R III is substantially heavier (157 percent) than the WG-90. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments. More than that, the WG-90 is water-proof up to 14m and can, thus, be used for underwater photography.
The power pack in the RX1R III can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The WG-90 was launched at a markedly lower price (by 95 percent) than the RX1R III, which puts it into a different market segment. 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.
Sensor comparison
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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Pentax WG-90 features a 1/2.3-inch sensor and the Sony RX1R III a full frame sensor. The sensor area in the RX1R III is 2936 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the WG-90 has a native 4:3 aspect ratio, while the one in the RX1R III offers a 3:2 aspect.

With 60.2MP, the RX1R III offers a higher resolution than the WG-90 (15.9MP), but the RX1R III nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 1.33μm for the WG-90) due to its larger sensor. Moreover, the RX1R III is a somewhat more recent model (by 1 year and 8 months) than the WG-90, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
The resolution advantage of the Sony RX1R III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1R III for good quality output (200 dots per inch) amounts to 47.5 x 31.7 inches or 120.7 x 80.5 cm, for very good quality (250 dpi) 38 x 25.3 inches or 96.6 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.5 x 53.6 cm. The corresponding values for the Pentax WG-90 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 RX1R III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Pentax WG-90 has a native sensitivity range from ISO 125 to ISO 6400. The corresponding ISO settings for the Sony Cyber-shot DSC-RX1R III are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.
Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

For many cameras, data on sensor performance has been reported by DXO Mark. 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").

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 RX1R III provides a better video resolution than the WG-90. It can shoot movie footage at 4K/30p, while the Pentax is limited to 1080/60p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX1R III has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the WG-90 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Pentax WG-90 and Sony RX1R III in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The WG-90 has one, while the RX1R III does not. While the built-in flash of the WG-90 is not very powerful, it can at times be useful as a fill-in light.
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, the RX1R III is one of those camera that have an additional 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 Pentax WG-90 and the Sony RX1R III both have 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 WG-90 is equipped with a zoom lens, while the RX1R III comes with a built-in prime. The WG-90 has a 28-140mm f/3.5-5.5 optic and the RX1R III offers a 35mm f/2.0 (focal lengths in full frame equivalent terms). Hence, the Pentax provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Sony. The RX1R III offers the faster maximum aperture.
Concerning the storage of imaging data, both the WG-90 and the RX1R III write their files to SDXC cards. The RX1R III supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the WG-90 cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison
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.

If the number of relative strengths (bullet points above) is taken as a guide, the RX1R III is the clear winner of the contest (22 : 7 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 Pentax WG-90 and the Sony RX1R III place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the WG-90 and the RX1R III in practical situations. 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.
Expert reviews
This is why expert reviews 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.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
