Canon M6 Mark II vs Olympus E-520
The Canon EOS M6 Mark II and the Olympus E-520 are two digital cameras that were announced, respectively, in August 2019 and May 2008. The M6 Mark II is a mirrorless interchangeable lens camera, while the E-520 is a DSLR. The cameras are based on an APS-C (M6 Mark II) and a Four Thirds (E-520) sensor. The Canon has a resolution of 32.3 megapixels, whereas the Olympus provides 10 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 EOS M6 Mark II and the Olympus E-520? 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.
The side-by-side display below illustrates the physical size and weight of the Canon M6 Mark II and the Olympus E-520. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-520 is considerably larger (49 percent) than the Canon M6 Mark II. Moreover, the E-520 is markedly heavier (31 percent) than the M6 Mark II. In this context, it is worth noting that neither the M6 Mark II nor the E-520 are weather-sealed.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the M6 Mark II gets 305 shots out of its LP-E17 battery, while the E-520 can take 750 images on a single charge of its BLM-1 power pack. The power pack in the M6 Mark II 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 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 E-520 was launched at a somewhat lower price (by 18 percent) than the M6 Mark II, which makes it more attractive for photographers on a tight budget. 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.
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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 M6 Mark II features an APS-C sensor and the Olympus E-520 a Four Thirds sensor. The sensor area in the E-520 is 33 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the M6 Mark II has a native 3:2 aspect ratio, while the one in the E-520 offers a 4:3 aspect.
With 32.3MP, the M6 Mark II offers a higher resolution than the E-520 (10MP), but the M6 Mark II has smaller individual pixels (pixel pitch of 3.23μm versus 4.74μm for the E-520). However, the M6 Mark II is a much more recent model (by 11 years and 3 months) than the E-520, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon M6 Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M6 Mark II for good quality output (200 dots per inch) amounts to 34.8 x 23.2 inches or 88.4 x 58.9 cm, for very good quality (250 dpi) 27.8 x 18.6 inches or 70.7 x 47.1 cm, and for excellent quality (300 dpi) 23.2 x 15.5 inches or 58.9 x 39.3 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 M6 Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS M6 Mark II has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Olympus E-520 are ISO 100 to ISO 1600 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 M6 Mark II indeed provides movie recording capabilities, while the E-520 does not. The highest resolution format that the M6 Mark II can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-520 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M6 Mark II relies on live view and the rear LCD for framing. That said, the M6 Mark II can be equipped with an optional viewfinder – the EVF-DC2. The following table reports on some other key feature differences and similarities of the Canon M6 Mark II, the Olympus E-520, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M6 Mark II 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 M6 Mark II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping 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 M6 Mark 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 Canon M6 Mark 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.
The M6 Mark II writes its imaging data to SDXC cards, while the E-520 uses Compact Flash or xD Picture cards. The E-520 features dual card slots, which can be very useful in case a memory card fails. In contrast, the M6 Mark II only has one slot.
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 EOS M6 Mark II and Olympus E-520 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M6 Mark II offers wifi support, while the E-520 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The M6 Mark II is a recent model that features in the current product line-up of Canon. In contrast, the E-520 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the E-520 from Olympus. 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.

If the count of individual advantages (bullet points above) is taken as a guide, the M6 Mark II is the clear winner of the match-up (22 : 6 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.

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 M6 Mark II and the E-520 in practical situations. 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 why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

The above review scores should be interpreted with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
