Canon R3 vs Olympus E-M10 IV
The Canon EOS R3 and the Olympus OM-D E-M10 Mark IV are two digital cameras that were officially introduced, respectively, in September 2021 and August 2020. Both the R3 and the E-M10 IV are mirrorless interchangeable lens cameras that are based on a full frame (R3) and a Four Thirds (E-M10 IV) sensor. The Canon has a resolution of 24 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 R3 and the Olympus OM-D E-M10 Mark IV? 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 R3 and the Olympus E-M10 IV 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 width, height and depth measures are rounded to the nearest millimeter.
The E-M10 IV can be obtained in two different colors (black, silver), while the R3 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-M10 IV is considerably smaller (52 percent) than the Canon R3. Moreover, the E-M10 IV is substantially lighter (62 percent) than the R3. It is worth mentioning in this context that the R3 is splash and dust resistant, while the E-M10 IV 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 R3 gets 760 shots out of its Canon LP-E19 battery, while the E-M10 IV can take 360 images on a single charge of its Olympus BLS-50 power pack. As can be seen in the images above, the R3 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

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 E-M10 IV was launched at a markedly lower price (by 88 percent) than the R3, which puts it into a different 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.
Sensor comparison
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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon R3 features a full frame sensor and the Olympus E-M10 IV a Four Thirds sensor. The sensor area in the E-M10 IV 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 R3 has a native 3:2 aspect ratio, while the one in the E-M10 IV offers a 4:3 aspect.
With 24MP, the R3 offers a higher resolution than the E-M10 IV (20.2MP), but the R3 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 3.34μm for the E-M10 IV) due to its larger sensor. Moreover, the R3 is a somewhat more recent model (by 1 year and 1 month) than the E-M10 IV, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the E-M10 IV has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon R3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the R3 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-M10 IV are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.
The R3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS R3 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Olympus OM-D E-M10 Mark IV are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
In terms of underlying technology, the R3 is build around a Stacked BSI-CMOS sensor, while the E-M10 IV uses a CMOS imager. 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 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.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One feature that is present on the R3, but is missing on the E-M10 IV 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, both cameras under consideration feature an 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 R3 and the Olympus E-M10 IV 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.
The R3 writes its imaging data to CFexpress (type B) or SDXC cards, while the E-M10 IV uses SDXC cards. The R3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M10 IV only has one slot. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 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 R3 and Olympus OM-D E-M10 Mark IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the R3 has a microphone port, which is missing on the E-M10 IV. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Canon R3 (unlike the E-M10 IV) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the R3 and the E-M10 IV are recent models that are part of the current product line-up. The E-M10 IV replaced the earlier Olympus E-M10 III, while the R3 does not have a direct predecessor. Further information on the features and operation of the R3 and E-M10 IV can be found, respectively, in the Canon R3 Manual (free pdf) or the online Olympus E-M10 IV Manual.

- Faster burst: Shoots at higher frequency (15 vs 12 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (122x84mm vs 150x143mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 632g or 62 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (88 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in August 2020).
If the count of individual advantages (bullet points above) is taken as a guide, the R3 is the clear winner of the match-up (24 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 R3 and the Olympus E-M10 IV 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 R3 or the E-M10 IV 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
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
