Pentax K-S1 vs Ricoh WG-60
The Pentax K-S1 and the Ricoh WG-60 are two digital cameras that were revealed to the public, respectively, in August 2014 and October 2018. The K-S1 is a DSLR, while the WG-60 is a fixed lens compact. The cameras are based on an APS-C (K-S1) and a 1/2.3-inch (WG-60) sensor. The Pentax has a resolution of 20 megapixels, whereas the Ricoh provides 15.9 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Pentax K-S1 and the Ricoh WG-60? 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.
An illustration of the physical size and weight of the Pentax K-S1 and the Ricoh WG-60 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The K-S1 can be obtained in four different colors (black, grey, orange, white), while the WG-60 is available in two color-versions (black, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh WG-60 is considerably smaller (32 percent) than the Pentax K-S1. It is noteworthy in this context that the WG-60 is splash and dust-proof, while the K-S1 does not feature any corresponding weather-sealing. More than that, the WG-60 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-60 has a lens built in, whereas the K-S1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. 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-60 was launched at a lower price than the K-S1, 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Pentax K-S1 features an APS-C sensor and the Ricoh WG-60 a 1/2.3-inch sensor. The sensor area in the WG-60 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 5.6. The sensor in the K-S1 has a native 3:2 aspect ratio, while the one in the WG-60 offers a 4:3 aspect.
With 20MP, the K-S1 offers a higher resolution than the WG-60 (15.9MP), but the K-S1 nevertheless has larger individual pixels (pixel pitch of 4.28μm versus 1.33μm for the WG-60) due to its larger sensor. However, the WG-60 is a much more recent model (by 4 years and 1 month) than the K-S1, and its sensor will 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 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 Pentax K-S1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-S1 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Ricoh WG-60 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 K-S1 has a native sensitivity range from ISO 100 to ISO 51200. The corresponding ISO settings for the Ricoh WG-60 are ISO 125 to ISO 6400 (no boost).
Technology-wise, both cameras are equipped with CMOS (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 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 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).
Beyond body and sensor, cameras can and do differ across a range of features. For example, the K-S1 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the WG-60 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Pentax K-S1 and Ricoh WG-60 in connection with corresponding information for a sample of similar cameras.

The Ricoh WG-60 has 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.
Concerning the storage of imaging data, both the K-S1 and the WG-60 write their files to SDXC cards. The K-S1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the WG-60 cannot take advantage of Ultra High Speed SD cards.
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 K-S1 and Ricoh WG-60 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-S1 has a hotshoe, while the WG-60 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the K-S1 and the WG-60 have been discontinued, but can regularly be found used on ebay. The K-S1 was replaced by the Pentax K-S2, while the WG-60 does not have a direct successor. Further information on the features and operation of the K-S1 and WG-60 can be found, respectively, in the Pentax K-S1 Manual (free pdf) or the online Ricoh WG-60 Manual.
So what is the bottom line? Is there a clear favorite between the Pentax K-S1 and the Ricoh WG-60? Which camera is better? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Pentax K-S1:
- More detail: Offers more megapixels (20 vs 15.9MP) with a 14% higher linear resolution.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- 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 (921k vs 230k dots).
- Faster shutter: Has higher mechanical shutter speed (1/6000s vs 1/4000s) to freeze action.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (410 versus 300) on a single battery charge.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More heavily discounted: Has been available for much longer (launched in August 2014).
Advantages of the Ricoh WG-60:
- Faster burst: Shoots at higher frequency (8 vs 5.4 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Comes with an integrated lens, while the K-S1 requires a separate lens.
- More compact: Is smaller (123x62mm vs 121x93mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the K-S1).
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 14m).
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 4 years and 1 month of technical progress since the K-S1 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the K-S1 is the clear winner of the match-up (15 : 9 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 K-S1 and the Ricoh WG-60 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom Camera listings 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 says little about, for example, the shooting experience and imaging performance of the K-S1 and the WG-60 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.
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 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
