Canon M6 vs Olympus E-3
The Canon EOS M6 and the Olympus E-3 are two digital cameras that were announced, respectively, in February 2017 and October 2007. The M6 is a mirrorless interchangeable lens camera, while the E-3 is a DSLR. The cameras are based on an APS-C (M6) and a Four Thirds (E-3) sensor. The Canon has a resolution of 24 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 and the Olympus E-3? 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.
An illustration of the physical size and weight of the Canon M6 and the Olympus E-3 is provided 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 M6 can be obtained in two different colors (black, silver), while the E-3 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-3 is considerably larger (116 percent) than the Canon M6. Moreover, the E-3 is substantially heavier (125 percent) than the M6. It is noteworthy in this context that the E-3 is splash and dust-proof, while the M6 does not feature any corresponding weather-sealing.
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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. 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 M6 was launched at a markedly lower price (by 54 percent) than the E-3, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon M6 features an APS-C sensor and the Olympus E-3 a Four Thirds sensor. The sensor area in the E-3 is 32 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 has a native 3:2 aspect ratio, while the one in the E-3 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 24MP, the M6 offers a higher resolution than the E-3 (10MP), but the M6 has smaller individual pixels (pixel pitch of 3.72μm versus 4.74μm for the E-3). However, the M6 is a much more recent model (by 9 years and 4 months) than the E-3, 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 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M6 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus E-3 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 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS M6 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Olympus E-3 are ISO 100 to ISO 3200 (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 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 also of capturing video footage. The M6 indeed provides movie recording capabilities, while the E-3 does not. The highest resolution format that the M6 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-3 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M6 relies on live view and the rear LCD for framing. That said, the M6 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, the Olympus E-3, and comparable cameras.

|7.||Canon G7 X Mark II||none||n||3.0||1040||tilting||Y||1/2000s||8.0||Y||Y|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M6 has a touchscreen, while the E-3 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.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 Canon M6 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 writes its imaging data to SDXC cards, while the E-3 uses Compact Flash or xD Picture cards. The E-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the M6 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 and Olympus E-3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M6 offers wifi support, while the E-3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Olympus E-3 (unlike the M6) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the M6 and the E-3 have been discontinued, but can regularly be found used on eBay. The E-3 was replaced by the Olympus E-5, while the M6 was followed by the Canon M6 Mark II. 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 relative strengths (bullet points above) is taken as a measure, the M6 is the clear winner of the match-up (20 : 10 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the M6 or the E-3 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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 (amateurphotographer [AP], cameralabs [CL], 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
