Canon M3 vs Sony A7R IV
The Canon EOS M3 and the Sony Alpha A7R IV are two digital cameras that were revealed to the public, respectively, in February 2015 and July 2019. Both the M3 and the A7R IV are mirrorless interchangeable lens cameras that are based on an APS-C (M3) and a full frame (A7R IV) sensor. The Canon has a resolution of 24 megapixels, whereas the Sony provides 60.2 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 M3 and the Sony Alpha A7R 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 M3 and the Sony A7R 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 M3 can be obtained in two different colors (black, white), while the A7R IV 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 Sony A7R IV is considerably larger (64 percent) than the Canon M3. Moreover, the A7R IV is substantially heavier (82 percent) than the M3. It is noteworthy in this context that the A7R IV is splash and dust-proof, while the M3 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 M3 gets 250 shots out of its Canon LP-E17 battery, while the A7R IV can take 670 images on a single charge of its Sony NP-FZ100 power pack. The power pack in the A7R IV can be charged via the USB port, which can be very convenient when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M3 was launched at a markedly lower price (by 81 percent) than the A7R IV, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 M3 features an APS-C sensor and the Sony A7R IV a full frame sensor. The sensor area in the A7R IV is 156 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 60.2MP, the A7R IV offers a higher resolution than the M3 (24MP), but the A7R IV nevertheless has marginally larger individual pixels (pixel pitch of 3.76μm versus 3.72μm for the M3) due to its larger sensor. Moreover, the A7R IV is a much more recent model (by 4 years and 5 months) than the M3, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the A7R IV has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony A7R IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R IV for good quality output (200 dots per inch) amounts to 47.5 x 31.7 inches or 120.7 x 80.5 cm, for very good quality (250 dpi) 38 x 25.3 inches or 96.6 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.5 x 53.6 cm. The corresponding values for the Canon M3 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.
Unlike the M3, the A7R IV has the capacity to capture high quality composite images (241MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Canon EOS M3 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Alpha A7R IV are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.
In terms of underlying technology, the M3 is build around a CMOS sensor, while the A7R IV uses a BSI-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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. Of the two cameras under consideration, the A7R IV offers substantially better image quality than the M3 (overall score 27 points higher). The advantage is based on 3.2 bits higher color depth, 3 EV in additional dynamic range, and 1.5 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7R IV provides a better video resolution than the M3. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7R IV has an electronic viewfinder (5760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the M3 relies on live view and the rear LCD for framing. That said, the M3 can be equipped with an optional viewfinder – the EVF-DC1.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One difference between the cameras concerns the presence of an on-board flash. The M3 has one, while the A7R IV does not. While the built-in flash of the M3 is not very powerful, it can at times be useful as a fill-in light.
The M3 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 A7R IV does not have a selfie-screen.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 A7R IV 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 Sony A7R IV 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 M3 and the A7R IV write their files to SDXC cards. The A7R IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the M3 only has one slot. The A7R IV supports UHS-II cards (on both slots), while the M3 can use UHS-I cards.
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.

It is notable that the A7R IV has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The M3 lacks such a headphone port.
Studio photographers will appreciate that the Sony A7R IV (unlike the M3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the M3 and the A7R IV have been discontinued, but can regularly be found used on ebay. The M3 was replaced by the Canon M6, while the A7R IV was followed by the Sony A7R V. Further information on the features and operation of the M3 and A7R IV can be found, respectively, in the Canon M3 Manual (free pdf) or the online Sony A7R IV Manual.
Review summary
So how do things add up? Is the Canon M3 better than the Sony A7R IV or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS M3:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- More compact: Is smaller (111x68mm vs 129x96mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 299g or 45 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (81 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in February 2015).
Reasons to prefer the Sony Alpha A7R IV:
- More detail: Has more megapixels (60.2 vs 24MP), which boosts linear resolution by 58%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better image quality: Scores substantially higher (27 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (3.2 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (3 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.5 stops ISO advantage).
- Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- Easier framing: Has an electronic viewfinder for image composition and settings control.

- More modern: Reflects 4 years and 5 months of technical progress since the M3 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the A7R IV is the clear winner of the contest (25 : 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 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.
How about other alternatives? Do the specifications of the Canon M3 and the Sony A7R 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the M3 and the A7R IV in practical situations. 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 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], 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available. |
The above review scores should be interpreted 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
