Canon G7 X Mark III vs Olympus Stylus 1
The Canon PowerShot G7 X Mark III and the Olympus Stylus 1 are two digital cameras that were revealed to the public, respectively, in July 2019 and October 2013. Both the G7X Mark III and the Stylus 1 are fixed lens compact cameras that are based on an one-inch (G7X Mark III) and a 1/1.7-inch (Stylus 1) sensor. The Canon has a resolution of 20 megapixels, whereas the Olympus provides 11.8 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 Mark III and the Olympus Stylus 1? 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.
The side-by-side display below illustrates the physical size and weight of the Canon G7 X Mark III and the Olympus Stylus 1. 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 dimensions are rounded to the nearest millimeter.
The G7X Mark III can be obtained in two different colors (black, silver), while the Stylus 1 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 Stylus 1 is considerably larger (58 percent) than the Canon G7 X Mark III. Moreover, the Stylus 1 is markedly heavier (32 percent) than the G7X Mark III. In this context, it is worth noting that neither the G7X Mark III nor the Stylus 1 are weather-sealed.
Concerning battery life, the G7X Mark III gets 235 shots out of its NB-13L battery, while the Stylus 1 can take 410 images on a single charge of its BLS-5 power pack. The power pack in the G7X Mark III can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 Stylus 1 was somewhat cheaper (by 7 percent) than the G7X Mark III at launch, but both cameras fall into the same price category. 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 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 Mark III features an one-inch sensor and the Olympus Stylus 1 a 1/1.7-inch sensor. The sensor area in the Stylus 1 is 63 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 4.5. The sensor in the G7X Mark III has a native 3:2 aspect ratio, while the one in the Stylus 1 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around BSI-CMOS sensors.
With 20MP, the G7X Mark III offers a higher resolution than the Stylus 1 (11.8MP), but the G7X Mark III nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.91μm for the Stylus 1) due to its larger sensor. Moreover, the G7X Mark III is a much more recent model (by 5 years and 8 months) than the Stylus 1, 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 the Stylus 1 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 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X Mark III 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 Stylus 1 are 19.8 x 14.9 inches or 50.4 x 37.8 cm for good quality, 15.9 x 11.9 inches or 40.3 x 30.2 cm for very good quality, and 13.2 x 9.9 inches or 33.6 x 25.2 cm for excellent quality prints.
The Canon PowerShot G7 X Mark III has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Olympus Stylus 1 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G7X Mark III provides a higher video resolution than the Stylus 1. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Stylus 1 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G7X Mark III 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 G7 X Mark III, the Olympus Stylus 1, and comparable cameras.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the G7X Mark III is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Canon G7 X Mark III and the Olympus Stylus 1 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 Mark III and the Stylus 1 have zoom lenses built in. The G7X Mark III has a 24-100mm f/1.8-2.8 optic and the Stylus 1 offers a 28-300mm f/2.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Olympus, but less tele-photo reach at the long end. The G7X Mark III offers the faster maximum aperture.
Concerning the storage of imaging data, both the G7X Mark III and the Stylus 1 write their files to SDXC cards. The G7X Mark III supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the Stylus 1 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 Canon PowerShot G7 X Mark III and Olympus Stylus 1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X Mark III has a microphone port, which is missing on the Stylus 1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The G7X Mark III is a recent model that features in the current product line-up of Canon. In contrast, the Stylus 1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the Stylus 1 was succeeded by the Olympus Stylus 1s. 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 what conclusions can be drawn? Which of the two cameras – the Canon G7 X Mark III or the Olympus Stylus 1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

- More heavily discounted: Has been around for much longer (launched in October 2013).
If the count of individual advantages (bullet points above) is taken as a guide, the G7X Mark III is the clear winner of the match-up (20 : 6 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 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G7X Mark III or the Stylus 1. 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 expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
