Canon G1 X Mark III vs Olympus TG-4
The Canon PowerShot G1 X Mark III and the Olympus Tough TG-4 are two digital cameras that were announced, respectively, in October 2017 and April 2015. Both the G1X Mark III and the TG-4 are fixed lens compact cameras that are based on an APS-C (G1X Mark III) and a 1/2.3-inch (TG-4) sensor. The Canon has a resolution of 24 megapixels, whereas the Olympus 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 Canon PowerShot G1 X Mark III and the Olympus Tough TG-4? 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 Canon G1 X Mark III and the Olympus TG-4 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 width, height and depth measures are rounded to the nearest millimeter.
The TG-4 can be obtained in two different colors (black, red), while the G1X Mark 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 Olympus TG-4 is notably smaller (18 percent) than the Canon G1 X Mark III. Moreover, the TG-4 is substantially lighter (38 percent) than the G1X Mark III. 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 TG-4 is water-proof up to 15m and can, thus, be used for underwater photography.
Concerning battery life, the G1X Mark III gets 200 shots out of its NB-13L battery, while the TG-4 can take 380 images on a single charge of its LI-92B power pack. The power pack in the TG-4 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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-4 was launched at a markedly lower price (by 71 percent) than the G1X Mark 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 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 Canon G1 X Mark III features an APS-C sensor and the Olympus TG-4 a 1/2.3-inch sensor. The sensor area in the TG-4 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 G1X Mark III has a native 3:2 aspect ratio, while the one in the TG-4 offers a 4:3 aspect.
With 24MP, the G1X Mark III offers a higher resolution than the TG-4 (15.9MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.33μm for the TG-4) due to its larger sensor. Moreover, the G1X Mark III is a much more recent model (by 2 years and 6 months) than the TG-4, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon G1 X Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X Mark 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-4 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 G1X Mark III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot G1 X Mark III has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Olympus Tough TG-4 are ISO 100 to ISO 6400 (no boost).
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 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 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 G1X Mark III provides a higher frame rate than the TG-4. It can shoot video footage at 1080/60p, while the Olympus is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G1X Mark III has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the TG-4 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon G1 X Mark III, the Olympus TG-4, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G1X Mark III has a touchscreen, while the TG-4 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G1X Mark III has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the TG-4 does not have a selfie-screen.
The Canon G1 X Mark III and the Olympus TG-4 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 G1X Mark III and the TG-4 have zoom lenses built in. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the TG-4 offers a 25-100mm f/2.0-4.9 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Olympus, but less tele-photo reach at the long end. The TG-4 offers the faster maximum aperture.
Concerning the storage of imaging data, both the G1X Mark III and the TG-4 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.
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 Canon PowerShot G1 X Mark III and Olympus Tough TG-4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G1X Mark III has a hotshoe, while the TG-4 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Travel and landscape photographers will find it useful that the TG-4 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The G1X Mark III is a recent model that features in the current product line-up of Canon. In contrast, the TG-4 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the TG-4 was succeeded by the Olympus TG-5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Olympus websites.

If the number of relative strengths (bullet points above) is taken as a guide, the G1X Mark III is the clear winner of the match-up (18 : 10 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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.

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 G1X Mark III or the TG-4 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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], 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
