Going beyond this snapshot of core features and characteristics, what are the differences between the Pentax WG-90 and the Sony Alpha A7R IIIA? 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 side-by-side display below illustrates the physical size and weight of the Pentax WG-90 and the Sony A7R IIIA. 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 A7R IIIA 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 A7R IIIA is considerably larger (60 percent) than the Pentax 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 above size and weight comparisons are to some extent incomplete and possibly misleading, as the WG-90 has a lens built in, whereas the A7R IIIA 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 A7R IIIA and their specifications in the Sony FE Lens Catalog.

The power pack in the A7R IIIA can be charged via the USB port, which can be very convenient when travelling.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The WG-90 was launched at a lower price than the A7R IIIA, despite having a lens built 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 tend to 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 A7R IIIA a full frame sensor. The sensor area in the A7R IIIA is 2979 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 A7R IIIA offers a 3:2 aspect.

With 42.2MP, the A7R IIIA offers a higher resolution than the WG-90 (15.9MP), but the A7R IIIA nevertheless has larger individual pixels (pixel pitch of 4.52μm versus 1.33μm for the WG-90) due to its larger sensor. However, the WG-90 is a much more recent model (by 2 years and 7 months) than the A7R IIIA, and its sensor will have benefitted from technological advances during this time that 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 A7R IIIA implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R IIIA for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 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 A7R IIIA has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the WG-90, the A7R IIIA has the capacity to capture high quality composite images 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).

The Pentax WG-90 has a native sensitivity range from ISO 125 to ISO 6400. The corresponding ISO settings for the Sony Alpha A7R IIIA 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the A7R IIIA 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

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7R IIIA has an electronic viewfinder (3686k 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 following table reports on some other key feature differences and similarities of the Pentax WG-90, the Sony A7R IIIA, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The WG-90 has one, while the A7R IIIA 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 A7R IIIA 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 A7R IIIA 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 writes its imaging data to SDXC cards, while the A7R IIIA uses SDXC or Memory Stick PRO Duo cards. The A7R IIIA features dual card slots, which can be very useful in case a memory card fails. In contrast, the WG-90 only has one slot. The A7R IIIA supports UHS-II cards on its first slot and UHS-I on its second one, 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. The table below provides an overview of the connectivity of the Pentax WG-90 and Sony Alpha A7R IIIA and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R IIIA offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the WG-90 does not provide wifi capability.

Studio photographers will appreciate that the Sony A7R IIIA (unlike the WG-90) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the WG-90 and the A7R IIIA are recent models that are part of the current product line-up. The A7R IIIA replaced the earlier Sony A7R II, while the WG-90 does not have a direct predecessor. Further information on the features and operation of the WG-90 and A7R IIIA can be found, respectively, in the Pentax WG-90 Manual (free pdf) or the online Sony A7R IIIA Manual.

Review summary

So what is the bottom line? Is the Pentax WG-90 better than the Sony A7R IIIA or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Pentax WG-90:

• Ready to shoot: Has a lens built-in, whereas the A7R IIIA requires a separate lens.

• Faster buffer clearing: Supports Ultra High Speed (UHS-II and UHS-I) SDXC cards.
• More heavily discounted: Has been around for much longer (launched in April 2021).

If the count of relative strengths (bullet points above) is taken as a measure, the A7R IIIA is the clear winner of the contest (31 : 7 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 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 A7R IIIA place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens 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 A7R IIIA in practical situations. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
