Canon M5 vs Olympus E-3
The Canon EOS M5 and the Olympus E-3 are two digital cameras that were officially introduced, respectively, in September 2016 and October 2007. The M5 is a mirrorless interchangeable lens camera, while the E-3 is a DSLR. The cameras are based on an APS-C (M5) 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 M5 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.
The side-by-side display below illustrates the physical size and weight of the Canon M5 and the Olympus E-3. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size 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-3 is considerably larger (60 percent) than the Canon M5. Moreover, the E-3 is substantially heavier (105 percent) than the M5. It is noteworthy in this context that the E-3 is splash and dust-proof, while the M5 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M5 was launched at a markedly lower price (by 42 percent) than the E-3, which puts it into a different market segment. 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. 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. 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 M5 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 M5 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 M5 offers a higher resolution than the E-3 (10MP), but the M5 has smaller individual pixels (pixel pitch of 3.72μm versus 4.74μm for the E-3). However, the M5 is a much more recent model (by 8 years and 11 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 M5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M5 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 M5 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS M5 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).
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under review, the M5 provides substantially higher image quality than the E-3, with an overall score that is 21 points higher. This advantage is based on 1.8 bits higher color depth, 1.9 EV in additional dynamic range, and 1.1 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The M5 indeed provides movie recording capabilities, while the E-3 does not. The highest resolution format that the M5 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the M5 has an electronic viewfinder (2360k dots), while the E-3 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Canon M5 and Olympus E-3 along with similar information for a selection of comparators.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M5 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 M5 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 M5 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 M5 and Olympus E-3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

| NFC |
It is notable that the M5 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 M5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The M5 is a recent model that features in the current product line-up of Canon. In contrast, the E-3 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-3 was succeeded by the Olympus E-5. 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 M5 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 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the M5 or the E-3. 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.
This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
