Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus Tough TG-6 and the Ricoh GR 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

An illustration of the physical size and weight of the Olympus TG-6 and the Ricoh GR III is provided 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 width, height and depth dimensions are rounded to the nearest millimeter.

The TG-6 can be obtained in two different colors (black, red), while the GR 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 Ricoh GR III is notably smaller (9 percent) than the Olympus TG-6. However, the GR III is slightly heavier (2 percent) than the TG-6. It is worth mentioning in this context that the TG-6 is splash and dust resistant, while the GR III does not feature any corresponding weather-sealing. More than that, the TG-6 is water-proof up to 15m and can, thus, be used for underwater photography.

Concerning battery life, the TG-6 gets 340 shots out of its Olympus LI-92B battery, while the GR III can take 200 images on a single charge of its Ricoh DB-110 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

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 TG-6 was launched at a markedly lower price (by 50 percent) than the GR III, 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus TG-6 features a 1/2.3-inch sensor and the Ricoh GR III an APS-C sensor. The sensor area in the GR III is 1211 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the TG-6 has a native 4:3 aspect ratio, while the one in the GR III offers a 3:2 aspect.

With 24MP, the GR III offers a higher resolution than the TG-6 (12MP), but the GR III nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 1.53μm for the TG-6) due to its larger sensor. However, the TG-6 is a somewhat more recent model (by 2 months) than the GR III, and its sensor might 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 GR III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Ricoh GR III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR III for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus TG-6 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The GR III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Olympus Tough TG-6 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Ricoh GR III are ISO 100 to ISO 102400 (no boost).

In terms of underlying technology, the TG-6 is build around a BSI-CMOS sensor, while the GR III uses a 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the TG-6 provides a higher video resolution than the GR III. It can shoot video footage at 4K/30p, 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 TG-6 and the GR III 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. That said, the GR III can be equipped with an optional viewfinder – the GV-1. The adjacent table lists some of the other core features of the Olympus TG-6 and Ricoh GR III along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The TG-6 has one, while the GR III does not. While the built-in flash of the TG-6 is not very powerful, it can at times be useful as a fill-in light.

The Olympus TG-6 and the Ricoh GR 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 TG-6 is equipped with a zoom lens, while the GR III comes with a built-in prime. The TG-6 has a 25-100mm f/2.0-4.9 optic and the GR III offers a 28mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Olympus provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Ricoh. The TG-6 offers the faster maximum aperture.

Concerning the storage of imaging data, both the TG-6 and the GR III write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 Olympus Tough TG-6 and Ricoh GR III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GR III has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The TG-6 does not feature such an accessory-socket.

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

The GR III is a recent model that features in the current product line-up of Ricoh. In contrast, the TG-6 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the TG-6 was succeeded by the OM System TG-7. Further information on the features and operation of the TG-6 and GR III can be found, respectively, in the Olympus TG-6 Manual (free pdf) or the online Ricoh GR III Manual.

Review summary

So what is the bottom line? Is the Olympus TG-6 better than the Ricoh GR III or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Olympus Tough TG-6:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• Faster burst: Shoots at higher frequency (20 vs 4 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/2.8).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Longer lasting: Can take more shots (340 versus 200) 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 15m).
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).

Arguments in favor of the Ricoh GR III:

• More detail: Has more megapixels (24 vs 12MP), which boosts linear resolution by 44%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• 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 live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.

If the count of individual advantages (bullet points above) is taken as a guide, the GR III emerges as the winner of the match-up (13 : 11 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 Olympus TG-6 and the Ricoh GR 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 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 TG-6 and the GR III 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 hands-on reviews by experts 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
