Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS RP and the Olympus OM-D E-M5? 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

The side-by-side display below illustrates the physical size and weight of the Canon RP and the Olympus E-M5. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The E-M5 can be obtained in two different colors (black, silver), while the RP 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-M5 is somewhat smaller (4 percent) than the Canon RP. Moreover, the E-M5 is markedly lighter (12 percent) than the RP. It is noteworthy in this context that the E-M5 is splash and dust-proof, while the RP 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 RP gets 250 shots out of its LP-E17 battery, while the E-M5 can take 360 images on a single charge of its BLN-1 power pack. The power pack in the RP can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The two cameras under review were launched at the same price and fall into the same market segment. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon RP features a full frame sensor and the Olympus E-M5 a Four Thirds sensor. The sensor area in the E-M5 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 RP has a native 3:2 aspect ratio, while the one in the E-M5 offers a 4:3 aspect.

With 26MP, the RP offers a higher resolution than the E-M5 (15.9MP), but the RP nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 3.76μm for the E-M5) due to its larger sensor. Moreover, the RP is a much more recent model (by 7 years) than the E-M5, 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 RP implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RP for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 cm. The corresponding values for the Olympus E-M5 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 RP has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS RP 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 OM-D E-M5 are ISO 200 to ISO 25600 (no boost).

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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 RP provides substantially higher image quality than the E-M5, with an overall score that is 14 points higher. This advantage is based on 1.5 bits higher color depth, 0.4 EV of lower dynamic range, and 1.8 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the RP provides a higher video resolution than the E-M5. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the RP offers a substantially higher resolution than the one in the E-M5 (2360k vs 1440k dots). The table below summarizes some of the other core capabilities of the Canon RP and Olympus E-M5 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-M5 and the RP is in-body image stabilization (IBIS). The E-M5 reduces the risk of handshake-induced blur with all attached lenses, while the RP offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The Canon RP 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 RP and the E-M5 write their files to SDXC cards. The RP supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the E-M5 can use UHS-I cards (up to 104 MB/s).

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 RP and Olympus OM-D E-M5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RP has a microphone port, which is missing on the E-M5. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The RP is a recent model that features in the current product line-up of Canon. In contrast, the E-M5 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M5 was succeeded by the Olympus E-M5 II. Further information on the features and operation of the RP and E-M5 can be found, respectively, in the Canon RP Manual (free pdf) or the online Olympus E-M5 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon RP or the Olympus E-M5 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon EOS RP:

• More detail: Offers more megapixels (26 vs 15.9MP) with a 30% higher linear resolution.
• Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.5 bits more color depth).
• Better low-light sensitivity: Requires less light for good images (1.8 stops ISO advantage).
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
• 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.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.58x).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 610k dots).
• 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.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More modern: Reflects 7 years of technical progress since the E-M5 launch.

Reasons to prefer the Olympus OM-D E-M5:

• Faster burst: Shoots at higher frequency (9 vs 5 flaps/sec) to capture the decisive moment.
• Less heavy: Has a lower weight (by 60g or 12 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (360 versus 250) 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 heavily discounted: Has been around for much longer (launched in February 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the RP is the clear winner of the match-up (19 : 6 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 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 RP and the Olympus E-M5 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 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 RP or the E-M5 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.

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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
