Canon R vs Olympus E-PL7
The Canon EOS R and the Olympus PEN E-PL7 are two digital cameras that were announced, respectively, in September 2018 and August 2014. Both the Canon R and the E-PL7 are mirrorless interchangeable lens cameras that are based on a full frame (Canon R) and a Four Thirds (E-PL7) sensor. The Canon has a resolution of 30.1 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 R and the Olympus PEN E-PL7? 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 R and the Olympus E-PL7 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 width, height and depth dimensions are rounded to the nearest millimeter.
The E-PL7 can be obtained in two different colors (black, silver), while the Canon R 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-PL7 is considerably smaller (43 percent) than the Canon R. Moreover, the E-PL7 is substantially lighter (46 percent) than the Canon R. It is worth mentioning in this context that the Canon R is splash and dust resistant, while the E-PL7 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. 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 Canon R gets 370 shots out of its LP-E6N battery, while the E-PL7 can take 350 images on a single charge of its BLS-50 power pack. The power pack in the Canon R can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
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 E-PL7 was launched at a markedly lower price (by 74 percent) than the Canon R, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon R features a full frame sensor and the Olympus E-PL7 a Four Thirds sensor. The sensor area in the E-PL7 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the Canon R has a native 3:2 aspect ratio, while the one in the E-PL7 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 30.1MP, the Canon R offers a higher resolution than the E-PL7 (15.9MP), but the Canon R nevertheless has larger individual pixels (pixel pitch of 5.36μm versus 3.76μm for the E-PL7) due to its larger sensor. Moreover, the Canon R is a much more recent model (by 4 years) than the E-PL7, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Canon R for good quality output (200 dots per inch) amounts to 33.6 x 22.4 inches or 85.3 x 56.9 cm, for very good quality (250 dpi) 26.9 x 17.9 inches or 68.3 x 45.5 cm, and for excellent quality (300 dpi) 22.4 x 14.9 inches or 56.9 x 37.9 cm. The corresponding values for the Olympus E-PL7 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 Canon R has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS R has a native sensitivity range from ISO 100 to ISO 40000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Olympus PEN E-PL7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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 review, the Canon R provides substantially higher image quality than the E-PL7, with an overall score that is 17 points higher. This advantage is based on 1.8 bits higher color depth, 1.1 EV in additional dynamic range, and 1.7 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 Canon R provides a higher video resolution than the E-PL7. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Canon R has an electronic viewfinder (3690k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-PL7 relies on live view and the rear LCD for framing. That said, the E-PL7 can be equipped with an optional viewfinder – the VF-4. The adjacent table lists some of the other core features of the Canon R and Olympus E-PL7 along with similar information for a selection of comparators.

One feature that is present on the Canon R, but is missing on the E-PL7 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.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 Canon R 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-PL7 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 Canon R and the E-PL7 write their files to SDXC cards. The Canon R supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the E-PL7 can use UHS-I cards (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 R and Olympus PEN E-PL7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Canon R has a microphone port, which is missing on the E-PL7. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The Canon R is a recent model that features in the current product line-up of Canon. In contrast, the E-PL7 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-PL7 was succeeded by the Olympus E-PL8. 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 conclusions can be drawn? Is the Canon R better than the Olympus E-PL7 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS R:
- More detail: Offers more megapixels (30.1 vs 15.9MP) with a 40% higher linear resolution.
- Better image quality: Scores substantially higher (17 points) in the DXO overall assessment.

- More compact: Is smaller (115x67mm vs 139x98mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 303g or 46 percent) and is thus easier to take along.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced into a lower priced category (74 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in August 2014).
If the number of relative strengths (bullet points above) is taken as a guide, the Canon R is the clear winner of the match-up (22 : 6 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. 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 R and the Olympus E-PL7 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 incomplete and does no justice, for example, to the way the Canon R or the E-PL7 perform in practice. 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 why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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.
