Canon 100D vs Olympus E-M1 II
The Canon EOS 100D (called Canon SL1 in some regions) and the Olympus OM-D E-M1 Mark II are two digital cameras that were officially introduced, respectively, in March 2013 and September 2016. The 100D is a DSLR, while the E-M1 II is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (100D) 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 100D 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.
Body comparison
An illustration of the physical size and weight of the Canon 100D and the Olympus E-M1 II 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 size dimensions are rounded to the nearest millimeter.
The 100D 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 notably larger (15 percent) than the Canon 100D. Moreover, the E-M1 II is substantially heavier (41 percent) than the 100D. It is noteworthy in this context that the E-M1 II is splash and dust-proof, while the 100D 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. 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-M1 II). Mirrorless cameras, such as the E-M1 II, 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.
Concerning battery life, the 100D gets 380 shots out of its LP-E12 battery, while the E-M1 II can take 440 images on a single charge of its BLH-1 power pack.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 100D was launched at a markedly lower price (by 73 percent) than the E-M1 II, 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.
Sensor comparison
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 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-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 100D 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 100D. 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 100D). However, it should be noted that the E-M1 II is much more recent (by 3 years and 6 months) than the 100D, 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 100D, 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 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-M1 Mark II are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 64-25600.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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-M1 II offers substantially better image quality than the 100D (overall score 17 points higher). The advantage is based on 1.9 bits higher color depth, 1.5 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 are not only capable of taking still images, but also of capturing video footage. 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 100D. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M1 II has an electronic viewfinder (2360k 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 viewfinder in the E-M1 II offers a wider field of view (100%) than the one in the 100D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the E-M1 II has a higher magnification (0.74x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 100D and Olympus E-M1 II in connection with corresponding information for a sample of similar cameras.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One difference between the cameras concerns the presence of an on-board flash. The 100D has one, while the E-M1 II does not. While the built-in flash of the 100D is not very powerful, it can at times be useful as a fill-in light.
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 100D 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 100D 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 100D only has one slot. The E-M1 II supports UHS-II cards (on its first slot), while the 100D can use UHS-I cards.
Connectivity comparison
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-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 100D does not provide wifi capability.
Studio photographers will appreciate that the Olympus E-M1 II (unlike the 100D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 100D and the E-M1 II have been discontinued, but can regularly be found used on ebay. The 100D was replaced by the Canon 200D, while the E-M1 II was followed by the Olympus E-M1 III. Further information on the features and operation of the 100D and E-M1 II can be found, respectively, in the Canon 100D Manual (free pdf) or the online Olympus E-M1 II Manual.
Review summary
So what conclusions can be drawn? Which of the two cameras – the Canon 100D or the Olympus E-M1 II – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS 100D:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- More compact: Is smaller (117x91mm vs 134x91mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 167g or 29 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (73 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in March 2013).

Advantages of the Olympus OM-D E-M1 Mark II:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better image quality: Scores substantially higher (17 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).

- Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
- Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- More framing info: Has an electronic viewfinder that displays shooting data.
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.54x).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (18 vs 4.9 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Gets more shots (440 versus 380) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- 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.
- Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.

- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More modern: Reflects 3 years and 6 months of technical progress since the 100D launch.
If the count of relative strengths (bullet points above) is taken as a measure, the E-M1 II is the clear winner of the contest (27 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.
How about other alternatives? Do the specifications of the Canon 100D and the Olympus E-M1 II place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 100D 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.
Expert reviews
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], digitalcameraworld [DCW], 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available. |
The above review scores should be interpreted 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 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.
