Olympus E-M10 III versus Canon G9 X
The Olympus OM-D E-M10 Mark III and the Canon PowerShot G9 X are two digital cameras that were announced, respectively, in August 2017 and October 2015. The E-M10 III is a mirrorless interchangeable lens camera, while the G9X is a fixed lens compact. The cameras are based on a Four Thirds (E-M10 III) and an one-inch sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Canon provides 20 MP.
The side-by-side display below illustrates the physical size and weight of the Olympus E-M10 III and the Canon G9 X. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures 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 side – the E-M10 III – represents the basis for the calculations 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 G9 X is considerably smaller (45 percent) than the Olympus E-M10 III. In this context, it is worth noting that neither the E-M10 III nor the G9X are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X has a lens build in, whereas the E-M10 III is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the E-M10 III and their specifications in the Micro Four Thirds Lens Catalog.
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 G9X was launched at a lower price than the E-M10 III, despite having a lens build in. 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 size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixels 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus E-M10 III features a Four Thirds sensor and the Canon G9 X an one-inch sensor. The sensor area in the G9X is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the E-M10 III has a native 4:3 aspect ratio, while the one in the G9X offers a 3:2 aspect.
Despite having a smaller sensor, the G9X offers a higher resolution of 20 megapixel, compared with 15.9 MP of the E-M10 III. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 3.76μm for the E-M10 III). Moreover, it should be noted that the E-M10 III is a somewhat more recent model (by 1 year and 10 months) than the G9X, and its sensor might 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 E-M10 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Consistent information on actual sensor performance is available from DXO Mark for most 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 E-M10 III provides a higher video resolution than the G9X. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M10 III has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G9X relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Olympus E-M10 III and Canon G9 X in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The E-M10 III is a current model that online retailers, such as amazon, will have in stock. In contrast, the G9X has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the G9X was succeeded by the Canon G9 X Mark II.
So what is the bottom line? Which of the two cameras – the Olympus E-M10 III or the Canon G9 X – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Olympus OM-D E-M10 Mark III:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Features a larger and more technologically advanced imaging sensor.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (8.6 vs 6 flaps/sec) to capture the decisive moment.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- Longer lasting: Can take more shots (330 versus 220) on a single battery charge.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More modern: Is somewhat more recent (announced 1 year and 10 months after the G9X).
Reasons to prefer the Canon PowerShot G9 X:
- More detail: Has more megapixels (20 vs 15.9MP), which boosts linear resolution by 14%.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Ready to shoot: Has an integrated lens, whereas the E-M10 III necessitates an extra lens.
- More compact: Is smaller (98x58mm vs 122x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens build in (unlike the E-M10 III).
- More affordable: Was introduced at a lower price, despite coming with a build-in lens.
- More heavily discounted: Has been on the market for longer (launched in October 2015).
If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 III is the clear winner of the match-up (11 : 7 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.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the E-M10 III or the G9X. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
