Canon M vs Olympus E-M1 II
The Canon EOS M and the Olympus OM-D E-M1 Mark II are two digital cameras that were revealed to the public, respectively, in July 2012 and September 2016. Both the Canon M and the E-M1 II are mirrorless interchangeable lens cameras that are based on an APS-C (Canon M) and a Four Thirds (E-M1 II) sensor. The Canon has a resolution of 17.9 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 EOS M and the Olympus OM-D E-M1 Mark II? 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 physical size and weight of the Canon M and the Olympus E-M1 II are illustrated 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 Canon M can be obtained in two different colors (black, white), while the E-M1 II 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-M1 II is considerably larger (70 percent) than the Canon M. Moreover, the E-M1 II is substantially heavier (93 percent) than the Canon M. It is noteworthy in this context that the E-M1 II is splash and dust-proof, while the Canon M 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.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The Canon M was launched at a markedly lower price (by 70 percent) than the E-M1 II, 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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 M features an APS-C sensor and the Olympus E-M1 II a Four Thirds sensor. The sensor area in the E-M1 II 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 Canon M has a native 3:2 aspect ratio, while the one in the E-M1 II offers a 4:3 aspect.
Despite having a smaller sensor, the E-M1 II offers a higher resolution of 20.2 megapixels, compared with 17.9 MP of the Canon M. 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 3.34μm versus 4.31μm for the Canon M). However, it should be noted that the E-M1 II is much more recent (by 4 years and 1 month) than the Canon M, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the E-M1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Unlike the Canon M, the E-M1 II has the capacity to capture high quality composite images (50MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Canon EOS M has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Olympus OM-D E-M1 Mark II are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 64-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the E-M1 II offers substantially better image quality than the Canon M (overall score 15 points higher). The advantage is based on 1.6 bits higher color depth, 1.6 EV in additional dynamic range, and 0.7 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the E-M1 II provides a better video resolution than the Canon M. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M1 II has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the Canon M relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon M and Olympus E-M1 II in connection with corresponding information for a sample of similar cameras.
|2.||Olympus E-M1 II||2360||n||3.0||1037||swivel||Y||1/8000s||18.0||n||Y|
|5.||Canon G7 X||none||n||3.0||1040||tilting||Y||1/2000s||6.5||Y||Y|
|9.||Olympus E-M1 III||2360||n||3.0||1037||swivel||Y||1/8000s||18.0||n||Y|
One feature that differentiates the E-M1 II and the Canon M is in-body image stabilization (IBIS). The E-M1 II reduces the risk of handshake-induced blur with all attached lenses, while the Canon M offers no blur reduction with lenses that themselves do not provide optical image stabilization.The E-M1 II 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 Canon M 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 E-M1 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 Olympus E-M1 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.
Concerning the storage of imaging data, both the Canon M and the E-M1 II write their files to SDXC cards. The E-M1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the Canon M only has one slot. The E-M1 II supports UHS-II cards (on its first slot), while the Canon M can use UHS-I cards.
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 M and Olympus OM-D E-M1 Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M1 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the Canon M does not provide wifi capability.
Studio photographers will appreciate that the Olympus E-M1 II (unlike the Canon M) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The E-M1 II is a recent model that features in the current product line-up of Olympus. In contrast, the Canon M has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the Canon M was succeeded by the Canon EOS M3. 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.
So how do things add up? Is there a clear favorite between the Canon M and the Olympus E-M1 II? Which camera is better? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS M:

If the number of relative strengths (bullet points above) is taken as a guide, the E-M1 II is the clear winner of the contest (24 : 5 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the Canon M or the E-M1 II. 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 where reviews by experts come in. 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 assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
