Canon G7 X vs Olympus TG-5
The Canon PowerShot G7 X and the Olympus Tough TG-5 are two digital cameras that were announced, respectively, in September 2014 and May 2017. Both the G7X and the TG-5 are fixed lens compact cameras that are based on an one-inch (G7X) and a 1/2.3-inch (TG-5) sensor. The Canon has a resolution of 20 megapixels, whereas the Olympus provides 12 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 G7 X and the Olympus Tough TG-5? 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 G7 X and the Olympus TG-5 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-5 can be obtained in two different colors (black, red), while the G7X 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-5 is notably larger (21 percent) than the Canon G7 X. However, the TG-5 is markedly lighter (18 percent) than the G7X. It is noteworthy in this context that the TG-5 is splash and dust-proof, while the G7X does not feature any corresponding weather-sealing. More than that, the TG-5 is water-proof up to 15m and can, thus, be used for underwater photography.
Concerning battery life, the G7X gets 210 shots out of its NB-13L battery, while the TG-5 can take 340 images on a single charge of its LI-92B power pack. The power pack in the TG-5 can be charged via the USB port, 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. 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 obviously take relative prices into account. 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 TG-5 was launched at a markedly lower price (by 36 percent) than the G7X, 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.
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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G7 X features an one-inch sensor and the Olympus TG-5 a 1/2.3-inch sensor. The sensor area in the TG-5 is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the G7X has a native 3:2 aspect ratio, while the one in the TG-5 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors.
With 20MP, the G7X offers a higher resolution than the TG-5 (12MP), but the G7X nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.53μm for the TG-5) due to its larger sensor. However, the TG-5 is a much more recent model (by 2 years and 8 months) than the G7X, 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 G7 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X 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 Olympus TG-5 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 Canon PowerShot G7 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Olympus Tough TG-5 are ISO 100 to ISO 12800 (no boost).
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 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 TG-5 provides a better video resolution than the G7X. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The G7X and the TG-5 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.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X has a touchscreen, while the TG-5 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G7X 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-5 does not have a selfie-screen.
The Canon G7 X and the Olympus TG-5 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 G7X and the TG-5 have zoom lenses built in. The G7X has a 24-100mm f/1.8-2.8 optic and the TG-5 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 and the same tele-photo reach at the long end. The G7X offers the faster maximum aperture.
Concerning the storage of imaging data, both the G7X and the TG-5 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 G7 X and Olympus Tough TG-5 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 TG-5 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the G7X and the TG-5 have been discontinued, but can regularly be found used on eBay. The G7X was replaced by the Canon G7 X Mark II, while the TG-5 was followed by the Olympus TG-6. 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.
So how do things add up? Is the Canon G7 X better than the Olympus TG-5 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon PowerShot G7 X:
- More detail: Offers more megapixels (20 vs 12MP) with a 32% 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.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.0).
- Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
- More compact: Is smaller (103x60mm vs 113x66mm) and thus needs less room in the bag.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More heavily discounted: Has been available for much longer (launched in September 2014).
Arguments in favor of the Olympus Tough TG-5:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Faster burst: Shoots at higher frequency (20 vs 6.5 flaps/sec) to capture the decisive moment.
- Less heavy: Has a lower weight (by 54g or 18 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (340 versus 210) out of a single battery charge.
- Easier travel charging: Can be conveniently charged via its USB port.
- 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 15m).
- Easier geotagging: Features an internal GPS sensor to log localization data.
- More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
- More modern: Reflects 2 years and 8 months of technical progress since the G7X launch.
If the number of relative strengths (bullet points above) is taken as a guide, the G7X is the clear winner of the match-up (14 : 10 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Canon G7 X and the Olympus TG-5 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G7X or the TG-5 perform in practice. 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
