Canon G7 X Mark II versus Olympus E-M5 II
The Canon PowerShot G7 X Mark II and the Olympus OM-D E-M5 Mark II are two digital cameras that were announced, respectively, in February 2016 and February 2015. The G7X Mark II is a fixed lens compact, while the E-M5 II is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (G7X Mark II) and a Four Thirds (E-M5 II) sensor. The Canon has a resolution of 20 megapixel, whereas the Olympus provides 15.9 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.
Body comparison: Canon G7 X Mark II vs Olympus E-M5 II
The side-by-side display below illustrates the physical size and weight of the Canon G7 X Mark II and the Olympus E-M5 II. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the G7X Mark II – represents 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 Olympus E-M5 II is considerably larger (63 percent) than the Canon G7 X Mark II. It is noteworthy in this context that the E-M5 II is splash and dust-proof, while the G7X Mark II does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X Mark II has a lens build 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 find an overview of optics for the E-M5 II 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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X Mark II was launched at a lower price than the E-M5 II, 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.
Sensor comparison: Canon G7 X Mark II vs Olympus E-M5 II
The size of the imaging sensor is a crucial determinant 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 G7 X Mark II 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 G7X Mark II has a native 3:2 aspect ratio, while the one in the E-M5 II offers a 4:3 aspect.
Despite having a smaller sensor, the Canon G7 X Mark II offers a higher resolution of 20 megapixel, compared with 15.9 MP of the Olympus E-M5 II. 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-M5 II). However, it should be noted that the G7X Mark II is a somewhat more recent model (by 1 year) than the E-M5 II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
Unlike the G7X Mark II, 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).
For most cameras, data on sensor performance has been reported by DXO Mark. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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, and both provide the same movie specifications (1080/60p).
Feature comparison: Canon G7 X Mark II vs Olympus E-M5 II
Apart from body and sensor, cameras can and do differ across a variety 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 G7X Mark II relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon G7 X Mark II and Olympus E-M5 II along with similar information for a selection of comparators.

- Faster burst: Shoots at higher frequency (10 vs 8 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 (310 versus 265) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- More heavily discounted: Has been on the market for longer (launched in February 2015).
If the count of relative strengths (bullet points above) is taken as a measure, the E-M5 II emerges as the winner of the match-up (10 : 7 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.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G7X Mark II or the E-M5 II handle or perform in practice. 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 where reviews by experts come in.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
