Canon G5 X versus Canon G1 X Mark III
The Canon PowerShot G5 X and the Canon PowerShot G1 X Mark III are two digital cameras that were announced, respectively, in October 2015 and October 2017. Both the G5X and the G1X Mark III are fixed lens compact cameras that are based on an one-inch (G5X) and an APS-C sensor. The G5X has a resolution of 20 megapixel, whereas the G1X Mark III provides 24 MP.
The side-by-side display below illustrates the physical size and weight of the Canon G5 X and the Canon G1 X Mark III. 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. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the G5X – represents the basis or 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G1 X Mark III is somewhat larger (5 percent) than the Canon G5 X. Moreover, the G1X Mark III is markedly heavier (13 percent) than the G5X. It is noteworthy in this context that the G1X Mark III is splash and dust-proof, while the G5X does not feature any corresponding weather-sealing.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G5X was launched at a markedly lower price (by 38 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon G5 X features an one-inch sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 186 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the G1X Mark III offers a higher resolution than the G5X (20MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G5X) due to its larger sensor. Moreover, the G1X Mark III is a much more recent model (by 2 years) than the G5X, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a range of features. The G5X and the G1X Mark III are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2360k dots. The adjacent table lists some of the other core features of the Canon G5 X and Canon G1 X Mark III along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the G5X and the G1X Mark III have zoom lenses build in. The G5X has a 24-100mm f/1.8-2.8 optic and the G1X Mark III offers a 24-72mm f/2.8-5.6 (focal lengths in full frame equivalent terms). Hence, the G5X and G1X Mark III provide the same view at the wide-angle end, but the G1X Mark III has less tele-photo reach at the long end. The G5X offers the faster maximum aperture.
Both the G5X and the G1X Mark III are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The G1X Mark III replaced the earlier Canon G1 X Mark II, while the G5X does not have a direct predecessor.
So how do things add up? Which of the two cameras – the Canon G5 X or the Canon G1 X Mark III – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon PowerShot G5 X:
- Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.8).
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Less heavy: Is lighter (by 46g or 12 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in October 2015).
Arguments in favor of the Canon PowerShot G1 X Mark III:
- More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
- Better image quality: Is equipped with a larger and more technologically advanced sensor.
- Faster burst: Shoots at higher frequency (9 vs 5.9 flaps/sec) to capture the decisive moment.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- More modern: Reflects 2 years of technical progress since the G5X launch.
If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (5 points each). 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G5X or the G1X Mark III handle or 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 summarizes the assessments of some of the best known camera review sites.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
