Canon G7 X Mark III vs Olympus E-P7
The Canon PowerShot G7 X Mark III and the Olympus PEN E-P7 are two digital cameras that were announced, respectively, in July 2019 and June 2021. The G7X Mark III is a fixed lens compact, while the E-P7 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (G7X Mark III) and a Four Thirds (E-P7) sensor. The Canon has a resolution of 20 megapixels, whereas the Olympus provides 20.2 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 G7 X Mark III and the Olympus PEN E-P7? 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
An illustration of the physical size and weight of the Canon G7 X Mark III and the Olympus E-P7 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The G7X Mark III can be obtained in two different colors (black, silver), while the E-P7 is available in three color-versions (black, silver, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P7 is notably larger (27 percent) than the Canon G7 X Mark III. In this context, it is worth noting that neither the G7X Mark III nor the E-P7 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X Mark III has a lens built in, whereas the E-P7 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-P7 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the G7X Mark III gets 235 shots out of its Canon NB-13L battery, while the E-P7 can take 360 images on a single charge of its Olympus BLS-50 power pack. The power pack in the G7X Mark III 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X Mark III was launched at a lower price than the E-P7, 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.
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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G7 X Mark III features an one-inch sensor and the Olympus E-P7 a Four Thirds sensor. The sensor area in the E-P7 is 95 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 III has a native 3:2 aspect ratio, while the one in the E-P7 offers a 4:3 aspect.
With 20.2MP, the E-P7 offers a higher resolution than the G7X Mark III (20MP), but the E-P7 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the G7X Mark III) due to its larger sensor. Moreover, the E-P7 is a somewhat more recent model (by 1 year and 11 months) than the G7X Mark III, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The Canon PowerShot G7 X Mark III 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 PEN E-P7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
In terms of underlying technology, the G7X Mark III is build around a BSI-CMOS sensor, while the E-P7 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.
For many 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").

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
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, both cameras under consideration feature an 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 Canon G7 X Mark III and the Olympus E-P7 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 G7X Mark III and the E-P7 write their files to SDXC cards. The E-P7 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G7X Mark III can use UHS-I cards (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 G7 X Mark III and Olympus PEN E-P7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X Mark III has a microphone port, which is missing on the E-P7. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the G7X Mark III and the E-P7 are recent models that are part of the current product line-up. The G7X Mark III replaced the earlier Canon G7X Mark II, while the E-P7 followed on from the Olympus E-P5. Further information on the features and operation of the G7X Mark III and E-P7 can be found, respectively, in the Canon G7 X Mark III Manual (free pdf) or the online Olympus E-P7 Manual.
Review summary
So how do things add up? Is there a clear favorite between the Canon G7 X Mark III and the Olympus E-P7? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon PowerShot G7 X Mark III:
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Faster burst: Shoots at higher frequency (30 vs 8.7 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has a lens built-in, whereas the E-P7 requires a separate lens.
- More compact: Is smaller (105x61mm vs 118x69mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-P7).
- Easier travel charging: Can be conveniently charged via its USB port.
- Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
- 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 July 2019).
Arguments in favor of the Olympus PEN E-P7:
- 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.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (360 versus 235) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More modern: Was introduced somewhat (1 year and 11 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the E-P7 comes out slightly ahead of the G7X Mark III (10 : 9 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 when reflecting and deciding 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.
How about other alternatives? Do the specifications of the Canon G7 X Mark III and the Olympus E-P7 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 G7X Mark III and the E-P7 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 why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
