Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G9 X and the Olympus PEN E-PL8? 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon G9 X and the Olympus E-PL8. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

The G9X can be obtained in two different colors (black, silver), while the E-PL8 is available in three color-versions (black, brown, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PL8 is notably larger (36 percent) than the Canon G9 X. In this context, it is worth noting that neither the G9X nor the E-PL8 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X has a lens built in, whereas the E-PL8 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-PL8 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G9X gets 220 shots out of its Canon NB-13L battery, while the E-PL8 can take 350 images on a single charge of its Olympus BLS-50 power pack. The power pack in the G9X can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will naturally be influenced heavily by the price. 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 was launched at a lower price than the E-PL8, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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 features an one-inch sensor and the Olympus E-PL8 a Four Thirds sensor. The sensor area in the E-PL8 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 has a native 3:2 aspect ratio, while the one in the E-PL8 offers a 4:3 aspect.

Despite having a smaller sensor, the Canon G9 X offers a higher resolution of 20 megapixels, compared with 15.9 MP of the Olympus E-PL8. 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 3.76μm for the E-PL8). Moreover, it should be noted that the E-PL8 is a somewhat more recent model (by 11 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 pixel-units.

The resolution advantage of the Canon G9 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G9X 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-PL8 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

The Canon PowerShot G9 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Olympus PEN E-PL8 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the G9X is build around a BSI-CMOS sensor, while the E-PL8 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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"). 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G9X provides a higher frame rate than the E-PL8. It can shoot video footage at 1080/60p, while the Olympus is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The G9X and the E-PL8 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. That said, the E-PL8 can be equipped with an optional viewfinder – the VF-4. The table below summarizes some of the other core capabilities of the Canon G9 X and Olympus E-PL8 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The G9X has one, while the E-PL8 does not. While the built-in flash of the G9X is not very powerful, it can at times be useful as a fill-in light.

The Canon G9 X and the Olympus E-PL8 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.

Concerning the storage of imaging data, both the G9X and the E-PL8 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.

Connectivity comparison

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 and Olympus PEN E-PL8 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-PL8 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The G9X does not feature such an accessory-socket.

Both the G9X and the E-PL8 have been discontinued, but can regularly be found used on ebay. The G9X was replaced by the Canon G9 X Mark II, while the E-PL8 was followed by the Olympus E-PL9. Further information on the features and operation of the G9X and E-PL8 can be found, respectively, in the Canon G9 X Manual (free pdf) or the online Olympus E-PL8 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon G9 X or the Olympus E-PL8 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon PowerShot G9 X:

• More detail: Offers more megapixels (20 vs 15.9MP) with a 14% higher linear resolution.
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Ready to shoot: Has a lens built-in, whereas the E-PL8 requires a separate lens.
• More compact: Is smaller (98x58mm vs 115x67mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-PL8).
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been on the market for longer (launched in October 2015).

Reasons to prefer the Olympus PEN E-PL8:

• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Longer lasting: Gets more shots (350 versus 220) out of a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More modern: Was introduced somewhat (11 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the E-PL8 emerges as the winner of the match-up (13 : 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 and the Olympus E-PL8 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens 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 says little about, for example, the shooting experience and imaging performance of the G9X and the E-PL8 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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. Also, please note that some of the review sites have changed their methodology and reporting over time.
