Going beyond this snapshot of core features and characteristics, what are the differences between the Pentax WG-90 and the Ricoh WG-6? 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 Ricoh WG-6. 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 WG-90 can be obtained in two different colors (black, blue), while the WG-6 is also available in two color-versions, but different ones (black, orange).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh WG-6 is somewhat larger (2 percent) than the Pentax WG-90. Moreover, the WG-6 is markedly heavier (27 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, both cameras are water-proof and can, thus, be used for underwater photography.

The power pack in the WG-6 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. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The WG-90 was launched at a markedly lower price (by 30 percent) than the WG-6, which puts it into a different market segment. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.

Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

While the two cameras under review share the same sensor size, the WG-6 offers a higher resolution of 20.2 megapixels, compared with 15.9 MP of the WG-90. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the WG-6 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 1.33μm for the WG-90). Moreover, it should be noted, that the WG-90 is much more recent (by 4 years and 8 months) than the WG-6, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. 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 Ricoh WG-6 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the WG-6 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 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 Pentax WG-90 has a native sensitivity range from ISO 125 to ISO 6400. The Ricoh WG-6 offers exactly the same ISO settings.

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 assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the WG-6 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. The WG-90 and the WG-6 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The adjacent table lists some of the other core features of the Pentax WG-90 and Ricoh WG-6 along with similar information for a selection of comparators.

The Pentax WG-90 and the Ricoh WG-6 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.

Both the WG-90 and the WG-6 have zoom lenses built in. Both optics have identical focal length range and aperture specifications (5-25mm f/3.5-5.5). Both cameras offer the same maximum aperture.

Concerning the storage of imaging data, both the WG-90 and the WG-6 write their files to SDXC 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 Ricoh WG-6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Travel and landscape photographers will find it useful that the WG-6 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the WG-90 and the WG-6 are recent models that are part of the current product line-up. The WG-6 replaced the earlier Ricoh WG-5, while the WG-90 does not have a direct predecessor. Further information on the features and operation of the WG-90 and WG-6 can be found, respectively, in the Pentax WG-90 Manual (free pdf) or the online Ricoh WG-6 Manual.

Review summary

So what is the bottom line? Is the Pentax WG-90 better than the Ricoh WG-6 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Pentax WG-90:

• Faster burst: Shoots at higher frequency (8 vs 1 flaps/sec) to capture the decisive moment.
• Less heavy: Is lighter (by 52g or 21 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (30 percent cheaper at launch).
• More modern: Reflects 4 years and 8 months of technical progress since the WG-6 launch.

Advantages of the Ricoh WG-6:

• More detail: Has more megapixels (20.2 vs 15.9MP), which boosts linear resolution by 13%.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
• Longer lasting: Gets more shots (340 versus 300) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• More heavily discounted: Has been around for much longer (launched in February 2019).

If the count of relative strengths (bullet points above) is taken as a measure, the WG-6 is the clear winner of the contest (9 : 4 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 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 Pentax WG-90 and the Ricoh WG-6 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the WG-90 or the WG-6 perform in practice. 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.

Expert reviews

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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
