Canon G9 X Mark II vs Olympus E-420
The Canon PowerShot G9 X Mark II and the Olympus E-420 are two digital cameras that were announced, respectively, in January 2017 and March 2008. The G9X Mark II is a fixed lens compact, while the E-420 is a DSLR. The cameras are based on an one-inch (G9X Mark II) and a Four Thirds (E-420) sensor. The Canon has a resolution of 20 megapixels, whereas the Olympus provides 10 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 G9 X Mark II and the Olympus E-420? 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 G9 X Mark II and the Olympus E-420. 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 G9X Mark II can be obtained in two different colors (black, silver), while the E-420 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 E-420 is considerably larger (108 percent) than the Canon G9 X Mark II. In this context, it is worth noting that neither the G9X Mark II nor the E-420 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X Mark II has a lens built in, whereas the E-420 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-420 and their specifications in the Four Thirds Lens Catalog.
Concerning battery life, the G9X Mark II gets 235 shots out of its NB-13L battery, while the E-420 can take 500 images on a single charge of its BLS-1 power pack. The power pack in the G9X Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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 G9X Mark II was launched at a lower price than the E-420, despite having a lens built in. 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 size of the sensor inside a digital camera is one of the key determinants 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 G9 X Mark II features an one-inch sensor and the Olympus E-420 a Four Thirds sensor. The sensor area in the E-420 is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the G9X Mark II has a native 3:2 aspect ratio, while the one in the E-420 offers a 4:3 aspect.
Despite having a smaller sensor, the Canon G9 X Mark II offers a higher resolution of 20 megapixels, compared with 10 MP of the Olympus E-420. This megapixels 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 4.74μm for the E-420). However, it should be noted that the G9X Mark II is much more recent (by 8 years and 10 months) than the E-420, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon G9 X Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G9X Mark II 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 E-420 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.
The Canon PowerShot G9 X Mark II has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Olympus E-420 are ISO 100 to ISO 1600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the G9X Mark II has a notably higher overall DXO score than the E-420 (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.4 bits higher color depth, 2.1 EV in additional dynamic range, and -0 stops of reduced low light sensitivity. 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 G9X Mark II indeed provides movie recording capabilities, while the E-420 does not. The highest resolution format that the G9X Mark II can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-420 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G9X Mark II 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 G9 X Mark II, the Olympus E-420, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G9X Mark II has a touchscreen, while the E-420 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The Canon G9 X Mark II has 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.
The G9X Mark II writes its imaging data to SDXC cards, while the E-420 uses Compact Flash or xD Picture cards. The E-420 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G9X Mark II only has one slot.
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 G9 X Mark II and Olympus E-420 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G9X Mark II offers wifi support, while the E-420 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The G9X Mark II is a recent model that features in the current product line-up of Canon. In contrast, the E-420 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the E-420 from Olympus. 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 is the bottom line? Is the Canon G9 X Mark II better than the Olympus E-420 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon PowerShot G9 X Mark II:
- More detail: Offers more megapixels (20 vs 10MP) with a 44% higher linear resolution.
- Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.

- More heavily discounted: Has been around for much longer (launched in March 2008).
If the number of relative strengths (bullet points above) is taken as a guide, the G9X Mark II is the clear winner of the match-up (19 : 7 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 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.
How about other alternatives? Do the specifications of the Canon G9 X Mark II and the Olympus E-420 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G9X Mark II or the E-420 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
