Body comparison

The side-by-side display below illustrates the physical size and weight of the Olympus E-520 and the Canon G7 X Mark III. 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 measures are rounded to the nearest millimeter.

The G7X Mark III can be obtained in two different colors (black, silver), while the E-520 is only available in black.

Compare E-520 versus G7X Mark III top
Comparison E-520 or G7X Mark III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G7 X Mark III is considerably smaller (49 percent) than the Olympus E-520. In this context, it is worth noting that neither the E-520 nor the G7X Mark III 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-520 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-520 and their specifications in the Four Thirds Lens Catalog.

Concerning battery life, the E-520 gets 750 shots out of its Olympus BLM-1 battery, while the G7X Mark III can take 235 images on a single charge of its Canon NB-13L power pack. The power pack in the G7X Mark III can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 Olympus E-520 features a Four Thirds sensor and the Canon G7 X Mark III an one-inch sensor. The sensor area in the G7X Mark III is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the E-520 has a native 4:3 aspect ratio, while the one in the G7X Mark III offers a 3:2 aspect.

Olympus E-520 and Canon G7 X Mark III sensor measures

Despite having a smaller sensor, the G7X Mark III offers a higher resolution of 20 megapixels, compared with 10 MP of the E-520. 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-520). However, it should be noted that the G7X Mark III is much more recent (by 11 years and 1 month) than the E-520, 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 G7 X Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X Mark III 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-520 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 Olympus E-520 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot G7 X Mark III are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 125-25600.

In terms of underlying technology, the E-520 is build around a CMOS sensor, while the G7X Mark III uses a BSI-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.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X Mark III has a touchscreen, while the E-520 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The G7X Mark III has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the E-520 does not have a selfie-screen.

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 G7X Mark III 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 Canon G7 X Mark III 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 E-520 writes its imaging data to Compact Flash or xD Picture cards, while the G7X Mark III uses SDXC cards. The E-520 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G7X Mark III only has one slot.

  • More heavily discounted: Has been available for much longer (launched in May 2008).

ilogo

Reasons to prefer the Canon PowerShot G7 X Mark III:

  • More detail: Has more megapixels (20 vs 10MP), which boosts linear resolution by 44%.
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 215k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (30 vs 3.5 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.
  • Ready to shoot: Comes with an integrated lens, while the E-520 requires a separate lens.
  • More compact: Is smaller (105x61mm vs 136x92mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the E-520).
  • 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).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Reflects 11 years and 1 month of technical progress since the E-520 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the G7X Mark III is the clear winner of the contest (18 : 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. 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.

E-520 07:18 G7X Mark III

How about other alternatives? Do the specifications of the Olympus E-520 and the Canon G7 X Mark III place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the E-520 and the G7X Mark III in practical situations. 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

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
