Canon 100D vs Olympus E-M10
The Canon EOS 100D (called Canon SL1 in some regions) and the Olympus OM-D E-M10 are two digital cameras that were announced, respectively, in March 2013 and January 2014. The 100D is a DSLR, while the E-M10 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (100D) and a Four Thirds (E-M10) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Olympus provides 15.9 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 100D vs Olympus E-M10
An illustration of the physical size and weight of the Canon 100D and the Olympus E-M10 is provided in the side-by-side display below. 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 measures are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 100D – represents 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 is notably smaller (8 percent) than the Canon 100D. Moreover, the E-M10 is slightly lighter (3 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the E-M10 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (100D) and the Micro Four Thirds Lens Catalog (E-M10). Mirrorless cameras, such as the E-M10, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 100D was launched at a somewhat lower price (by 21 percent) than the E-M10, 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.
Sensor comparison: Canon 100D vs Olympus E-M10
The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 100D features an APS-C sensor and the Olympus E-M10 a Four Thirds sensor. The sensor area in the E-M10 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 100D has a native 3:2 aspect ratio, while the one in the E-M10 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 17.9MP, the 100D offers a higher resolution than the E-M10 (15.9MP), but the 100D nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.76μm for the E-M10) due to its larger sensor. However, the E-M10 is a somewhat more recent model (by 10 months) than the 100D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the E-M10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.
The Canon EOS 100D 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-M10 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600..
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"). Of the two cameras under consideration, the E-M10 has a markedly higher DXO score than the 100D (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 1 EV in additional dynamic range, and 0.1 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).
Feature comparison: Canon 100D vs Olympus E-M10
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M10 has an electronic viewfinder (1440k dots), while the 100D 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 following table reports on some other key feature differences and similarities of the Canon 100D, the Olympus E-M10, and comparable cameras.

One feature that differentiates the E-M10 and the 100D is in-body image stabilization (IBIS). The E-M10 reduces the risk of handshake-induced blur with all attached lenses, while the 100D has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.
Concerning the storage of imaging data, both the 100D and the E-M10 write their files to SDXC cards.
Connectivity comparison: Canon 100D vs Olympus E-M10
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 100D and Olympus OM-D E-M10 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 100D has a microphone port, which is missing on the E-M10. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the 100D and the E-M10 have been discontinued, but can regularly be found used on eBay. The 100D was replaced by the Canon 200D, while the E-M10 was followed by the Olympus E-M10 II.
Review summary: Canon 100D vs Olympus E-M10
So how do things add up? Which of the two cameras – the Canon 100D or the Olympus E-M10 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS 100D:
- More detail: Offers more megapixels (17.9 vs 15.9MP) with a 8% higher linear resolution.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Longer lasting: Can take more shots (380 versus 320) on a single battery charge.
- More affordable: Was introduced into a lower priced segment (21 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in March 2013).
Reasons to prefer the Olympus OM-D E-M10:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
- More framing info: Has an electronic viewfinder that displays shooting data.
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (8 vs 4.9 flaps/sec) to capture the decisive moment.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More modern: Was introduced somewhat (10 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the E-M10 emerges as the winner of the match-up (10 : 8 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.
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 100D or the E-M10 handle or 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.

The above review scores should be interpreted with care, 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 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.
