Canon SL2 vs Olympus E-P1

The Canon EOS Rebel SL2 (called Canon 200D in some regions) and the Olympus PEN E-P1 are two digital cameras that were announced, respectively, in June 2017 and June 2009. The SL2 is a DSLR, while the E-P1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (SL2) and a Four Thirds (E-P1) sensor. The Canon has a resolution of 24 megapixels, whereas the Olympus provides 12.2 MP.

As their names suggest, both the Canon EOS Rebel SL2 and the Olympus PEN E-P1 belong to Canon's Rebel line of DSLR cameras. This range of APS-C cameras, which started out with the Canon EOS Digital Rebel in 2003, has been a big commercial success and the backbone of Canon's dominance in the digital camera market. The popularity of the Rebel cameras is the result of them inheriting much of the sensor and shooting technology from earlier released professional DSLRs, while being sold at a much more budget-friendly price point. The strong brand reputation of Canon and the comprehensive EOS system of compatible lenses and accessories further contributes to the appeal of the Rebel cams, including the Canon SL2 and Olympus E-P1. 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-P1? 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: Canon SL2 vs Olympus E-P1

The physical size and weight of the Canon SL2 and the Olympus E-P1 are illustrated 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.

The SL2 can be obtained in two different colors (black, white), while the E-P1 is available in three color-versions (black, silver, white).

Size Canon SL2 vs Olympus E-P1
Compare SL2 versus E-P1 top
Comparison SL2 or E-P1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P1 is notably smaller (25 percent) than the Canon SL2. Moreover, the E-P1 is markedly lighter (22 percent) than the SL2. In this context, it is worth noting that neither the SL2 nor the E-P1 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-P1). Mirrorless cameras, such as the E-P1, 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 SL2 gets 650 shots out of its LP-E17 battery, while the E-P1 can take 300 images on a single charge of its BLS-1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 SL2 was launched at a markedly lower price (by 31 percent) than the E-P1, 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: Canon SL2 vs Olympus E-P1

The size of the sensor inside a digital camera is one of the key determinants 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 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-P1 a Four Thirds sensor. The sensor area in the E-P1 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-P1 offers a 4:3 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon SL2 and Olympus E-P1 sensor measures

With 24MP, the SL2 offers a higher resolution than the E-P1 (12.2MP), but the SL2 has smaller individual pixels (pixel pitch of 3.72μm versus 4.29μm for the E-P1). However, the SL2 is a much more recent model (by 8 years) than the E-P1, and its sensor will have benefitted from technological advances during this time that 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 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Olympus E-P1 are 20.2 x 15.1 inch or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inch or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inch or 34.1 x 25.6 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-P1 are ISO 100 to ISO 6400 (no boost).

SL2 versus E-P1 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the SL2 provides substantially higher image quality than the E-P1, with an overall score that is 24 points higher. This advantage is based on 2.2 bits higher color depth, 3 EV in additional dynamic range, and 1 stops in additional low light sensitivity. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SL2 provides a higher video resolution than the E-P1. It can shoot video footage at 1080/60p, while the Olympus is limited to 720/30p.

 

Feature comparison: Canon SL2 vs Olympus E-P1

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the SL2 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon SL2, the Olympus E-P1, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The SL2 has one, while the E-P1 does not. While the built-in flash of the SL2 is not very powerful, it can at times be useful as a fill-in light.

The SL2 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the E-P1 does not have a selfie-screen.

The Canon SL2 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.

The SL2 writes its imaging data to SDXC cards, while the E-P1 uses SDHC cards. The SL2 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-P1 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Canon SL2 vs Olympus E-P1

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-P1 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-P1. 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-P1 have been discontinued, but can regularly be found used on eBay. The E-P1 was replaced by the Olympus E-P2, while the SL2 was followed by the Canon SL2. 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.


Review summary: Canon SL2 vs Olympus E-P1

So what is the bottom line? Is the Canon SL2 better than the Olympus E-P1 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

  • More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
  • More modern: Reflects 8 years of technical progress since the E-P1 launch.

ilogo

Reasons to prefer the Olympus PEN E-P1:

  • More compact: Is smaller (121x70mm vs 122x93mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 98g or 22 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 heavily discounted: Has been around for much longer (launched in June 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the SL2 is the clear winner of the match-up (23 : 5 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.

SL2 23:05 E-P1

How about other alternatives? Do the specifications of the Canon SL2 and the Olympus E-P1 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 incomplete and does no justice, for example, to the way the SL2 or the E-P1 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews: Canon SL2 vs Olympus E-P1

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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, please note that some of the review sites have changed their methodology and reporting over time.
