If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon M100 is notably smaller (27 percent) than the Olympus E-M10 II. Moreover, the M100 is markedly lighter (23 percent) than the E-M10 II. In this context, it is worth noting that neither the E-M10 II nor the M100 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 E-M10 II gets 320 shots out of its BLS-50 battery, while the M100 can take 295 images on a single charge of its LP-E12 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. 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 M100 was launched at a markedly lower price (by 38 percent) than the E-M10 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.

 

Sensor comparison: Olympus E-M10 II vs Canon M100

The size of the imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Olympus E-M10 II features a Four Thirds sensor and the Canon M100 an APS-C sensor. The sensor area in the M100 is 48 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.6. The sensor in the E-M10 II has a native 4:3 aspect ratio, while the one in the M100 offers a 3:2 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Olympus E-M10 II and Canon M100 sensor measures

With 24MP, the M100 offers a higher resolution than the E-M10 II (15.9MP), but the M100 has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.76μm for the E-M10 II). Yet, the M100 is a much more recent model (by 2 years) than the E-M10 II, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the E-M10 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The M100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Olympus OM-D E-M10 Mark II has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon EOS M100 are ISO 100 to ISO 25600 (no boost).

E-M10 II versus M100 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the M100 has a markedly higher DXO score than the E-M10 II (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.4 bits higher color depth, 0.4 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Olympus E-M10 II vs Canon M100

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M10 II has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the M100 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Olympus E-M10 II and Canon M100 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-M10 II and the M100 is in-body image stabilization (IBIS). The E-M10 II reduces the risk of handshake-induced blur with all attached lenses, while the M100 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The M100 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-M10 II does not have a selfie-screen.

Concerning the storage of imaging data, both the E-M10 II and the M100 write their files to SDXC cards.

Connectivity comparison: Olympus E-M10 II vs Canon M100

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.

  • Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • More compact: Is smaller (108x67mm vs 120x83mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 88g or 23 percent) and is thus easier to take along.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
  • More modern: Reflects 2 years of technical progress since the E-M10 II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the M100 is the clear winner of the contest (12 : 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.

E-M10 II 06:12 M100

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the E-M10 II or the M100. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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.
