Canon SL2 vs Olympus E-PL9
The Canon EOS Rebel SL2 (called Canon 200D in some regions) and the Olympus PEN E-PL9 are two digital cameras that were officially introduced, respectively, in June 2017 and February 2018. The SL2 is a DSLR, while the E-PL9 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (SL2) and a Four Thirds (E-PL9) sensor. The Canon has a resolution of 24 megapixels, whereas the Olympus provides 15.9 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 Rebel SL2 and the Olympus PEN E-PL9? 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 SL2 and the Olympus E-PL9 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 size dimensions are rounded to the nearest millimeter.
The SL2 can be obtained in two different colors (black, white), while the E-PL9 is available in four color-versions (black, brown, blue, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PL9 is considerably smaller (30 percent) than the Canon SL2. Moreover, the E-PL9 is markedly lighter (16 percent) than the SL2. In this context, it is worth noting that neither the SL2 nor the E-PL9 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 (SL2) and the Micro Four Thirds Lens Catalog (E-PL9). Mirrorless cameras, such as the E-PL9, 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 would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SL2 was somewhat cheaper (by 8 percent) than the E-PL9 at launch, but both cameras fall into the same price category. 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 size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 SL2 features an APS-C sensor and the Olympus E-PL9 a Four Thirds sensor. The sensor area in the E-PL9 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 SL2 has a native 3:2 aspect ratio, while the one in the E-PL9 offers a 4:3 aspect.
With 24MP, the SL2 offers a higher resolution than the E-PL9 (15.9MP), but the SL2 has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.76μm for the E-PL9). Moreover, the E-PL9 is a somewhat more recent model (by 7 months) than the SL2, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon SL2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SL2 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-PL9 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The SL2 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel SL2 has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Olympus PEN E-PL9 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
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. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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-PL9 provides a better video resolution than the SL2. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the SL2 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL9 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon SL2 and Olympus E-PL9 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-PL9 and the SL2 is in-body image stabilization (IBIS). The E-PL9 reduces the risk of handshake-induced blur with all attached lenses, while the SL2 offers no blur reduction with lenses that themselves do not provide optical image stabilization.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 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-PL9 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 Canon SL2 and the Olympus E-PL9 both have 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 SL2 and the E-PL9 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Rebel SL2 and Olympus PEN E-PL9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SL2 has a microphone port, which is missing on the E-PL9. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the SL2 and the E-PL9 have been discontinued, but can regularly be found used on eBay. The SL2 was replaced by the Canon SL2, while the E-PL9 was followed by the Olympus E-PL10. 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 what is the bottom line? Is there a clear favorite between the Canon SL2 and the Olympus E-PL9? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS Rebel SL2:
- More detail: Offers more megapixels (24 vs 15.9MP) with a 25% higher linear resolution.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Longer lasting: Can take more shots (650 versus 350) on a single battery charge.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More heavily discounted: Has been on the market for longer (launched in June 2017).
Arguments in favor of the Olympus PEN E-PL9:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Faster burst: Shoots at higher frequency (8.6 vs 5 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More compact: Is smaller (117x68mm vs 122x93mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 73g or 16 percent) and is thus easier to take along.
- 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.
- More modern: Was introduced somewhat (7 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (8 points each). 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 SL2 and the Olympus E-PL9 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 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 SL2 or the E-PL9. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

The review scores listed above should be treated with care, 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.
