Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G3 X and the Olympus OM-D E-M5 Mark II? 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: Canon G3 X vs Olympus E-M5 II

The physical size and weight of the Canon G3 X and the Olympus E-M5 II are illustrated in the side-by-side display below. 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 E-M5 II can be obtained in two different colors (black, silver), while the G3X is only available in black.

Compare G3X versus E-M5 II top
Comparison G3X or E-M5 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M5 II is notably larger (11 percent) than the Canon G3 X. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G3X has a lens built in, whereas the E-M5 II 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-M5 II and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G3X gets 300 shots out of its NB-10L battery, while the E-M5 II can take 310 images on a single charge of its BLN-1 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. 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 G3X was launched at a lower price than the E-M5 II, despite having a lens built 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.

 

Sensor comparison: Canon G3 X vs Olympus E-M5 II

The size of the sensor inside a digital camera is one of the key determinants 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G3 X features an one-inch sensor and the Olympus E-M5 II a Four Thirds sensor. The sensor area in the E-M5 II 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 G3X has a native 3:2 aspect ratio, while the one in the E-M5 II offers a 4:3 aspect.

Canon G3 X and Olympus E-M5 II sensor measures

Despite having a smaller sensor, the Canon G3 X offers a higher resolution of 20 megapixels, compared with 15.9 MP of the Olympus E-M5 II. 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-M5 II). However, it should be noted that the G3X is a somewhat more recent model (by 4 months) than the E-M5 II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

The resolution advantage of the Canon G3 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G3X for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inch or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inch or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inch or 46.3 x 30.9 cm. The corresponding values for the Olympus E-M5 II are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 cm for excellent quality prints.

Unlike the G3X, the E-M5 II has the capacity to capture high quality composite images (40MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Canon PowerShot G3 X 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 OM-D E-M5 Mark II are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

G3X versus E-M5 II MP

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. Of the two cameras under consideration, the E-M5 II has a markedly higher DXO score than the G3X (overall score 10 points higher), which will translate into better image quality. The advantage is based on 1.6 bits higher color depth, 0.2 EV in additional dynamic range, and 0.7 stops in additional 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 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, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Canon G3 X vs Olympus E-M5 II

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M5 II has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G3X relies on live view and the rear LCD for framing. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1.

One difference between the cameras concerns the presence of an on-board flash. The G3X has one, while the E-M5 II does not. While the built-in flash of the G3X is not very powerful, it can at times be useful as a fill-in light.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

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 E-M5 II 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 Olympus E-M5 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.

Concerning the storage of imaging data, both the G3X and the E-M5 II write their files to SDXC cards. The E-M5 II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G3X can use UHS-I cards (up to 104 MB/s).

 

Connectivity comparison: Canon G3 X vs Olympus E-M5 II

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 G3 X and Olympus OM-D E-M5 Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Olympus E-M5 II (unlike the G3X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the G3X and the E-M5 II are recent models that are part of the current product line-up. The E-M5 II replaced the earlier Olympus E-M5, while the G3X does not have a direct predecessor. 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.


Review summary: Canon G3 X vs Olympus E-M5 II

So what conclusions can be drawn? Which of the two cameras – the Canon G3 X or the Olympus E-M5 II – 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.

ilogo

Reasons to prefer the Canon PowerShot G3 X:

  • More detail: Offers more megapixels (20 vs 15.9MP) with a 14% higher linear resolution.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1037k dots).
  • Ready to shoot: Has a lens built-in, whereas the E-M5 II requires a separate lens.
  • 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 modern: Is somewhat more recent (announced 4 months after the E-M5 II).

ilogo

Arguments in favor of the Olympus OM-D E-M5 Mark II:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
  • Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 5.9 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More heavily discounted: Has been on the market for longer (launched in February 2015).

If the number of relative strengths (bullet points above) is taken as a guide, the E-M5 II is the clear winner of the contest (14 : 9 points). 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 before making a decision 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.

G3X 09:14 E-M5 II

How about other alternatives? Do the specifications of the Canon G3 X and the Olympus E-M5 II place the cameras among the top in their class? Find out in the latest Best Superzoom 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G3X or the E-M5 II. 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.

Expert reviews: Canon G3 X vs Olympus E-M5 II

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
