Going beyond this snapshot of core features and characteristics, what are the differences between the Ricoh WG-60 and the Canon PowerShot G7 X Mark II? 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

An illustration of the physical size and weight of the Ricoh WG-60 and the Canon G7 X Mark II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The WG-60 can be obtained in two different colors (black, red), while the G7X Mark II 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 Canon G7 X Mark II is notably smaller (15 percent) than the Ricoh WG-60. However, the G7X Mark II is substantially heavier (65 percent) than the WG-60. It is worth mentioning in this context that the WG-60 is splash and dust resistant, while the G7X Mark II 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 power pack in the G7X Mark II 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-60 was launched at a markedly lower price (by 60 percent) than the G7X Mark II, 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 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. 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 Ricoh WG-60 features a 1/2.3-inch sensor and the Canon G7 X Mark II an one-inch sensor. The sensor area in the G7X Mark II is 314 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.7. The sensor in the WG-60 has a native 4:3 aspect ratio, while the one in the G7X Mark II offers a 3:2 aspect.

With 20MP, the G7X Mark II offers a higher resolution than the WG-60 (15.9MP), but the G7X Mark II nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.33μm for the WG-60) due to its larger sensor. However, the WG-60 is a much more recent model (by 2 years and 8 months) than the G7X Mark II, 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 the WG-60 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon G7 X Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X Mark II 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 Ricoh WG-60 has a native sensitivity range from ISO 125 to ISO 6400. The corresponding ISO settings for the Canon PowerShot G7 X Mark II are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 125-25600.

In terms of underlying technology, the WG-60 is build around a CMOS sensor, while the G7X Mark II uses a BSI-CMOS imager. 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G7X Mark II provides a faster frame rate than the WG-60. It can shoot movie footage at 1080/60p, while the Ricoh is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The WG-60 and the G7X Mark II 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 Ricoh WG-60 and Canon G7 X Mark II along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X Mark II has a touchscreen, while the WG-60 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Ricoh WG-60 and the Canon G7 X Mark II 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-60 and the G7X Mark II have zoom lenses built in. The WG-60 has a 28-140mm f/3.5-5.5 optic and the G7X Mark II offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Ricoh, but less tele-photo reach at the long end. The G7X Mark II offers the faster maximum aperture.

Concerning the storage of imaging data, both the WG-60 and the G7X Mark II write their files to SDXC cards. The G7X Mark II 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.

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 Ricoh WG-60 and Canon PowerShot G7 X Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X Mark II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the WG-60 does not provide wifi capability.

Both the WG-60 and the G7X Mark II have been discontinued, but can regularly be found used on ebay. The G7X Mark II was replaced by the Canon G7 X Mark III, while the WG-60 does not have a direct successor. Further information on the features and operation of the WG-60 and G7X Mark II can be found, respectively, in the Ricoh WG-60 Manual (free pdf) or the online Canon G7 X Mark II Manual.

Review summary

So how do things add up? Which of the two cameras – the Ricoh WG-60 or the Canon G7 X Mark II – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Ricoh WG-60:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Less heavy: Is lighter (by 126g or 39 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (300 versus 265) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 14m).
• More affordable: Was introduced into a lower priced category (60 percent cheaper at launch).
• More modern: Reflects 2 years and 8 months of technical progress since the G7X Mark II launch.

Arguments in favor of the Canon PowerShot G7 X Mark II:

• More detail: Has more megapixels (20 vs 15.9MP), which boosts linear resolution by 14%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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.
• Better video: Provides higher movie framerates (1080/60p versus 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).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.

• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More compact: Is smaller (106x61mm vs 123x62mm) and will fit more readily into a bag.
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More heavily discounted: Has been around for much longer (launched in February 2016).

If the number of relative strengths (bullet points above) is taken as a guide, the G7X Mark II is the clear winner of the contest (21 : 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 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 Ricoh WG-60 and the Canon G7 X Mark II 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the WG-60 and the G7X Mark II 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 following table reports the overall ratings of the cameras as published by some of the major 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 ratings are only valid when referring 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
