Canon M50 Mark II vs Sony A7R IV
The Canon EOS M50 Mark II and the Sony Alpha A7R IV are two digital cameras that were revealed to the public, respectively, in October 2020 and July 2019. Both the M50 Mark II and the A7R IV are mirrorless interchangeable lens cameras that are based on an APS-C (M50 Mark II) 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 M50 Mark II 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.
An illustration of the physical size and weight of the Canon M50 Mark II 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 consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The M50 Mark II 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 notably larger (21 percent) than the Canon M50 Mark II. Moreover, the A7R IV is substantially heavier (72 percent) than the M50 Mark II. It is noteworthy in this context that the A7R IV is splash and dust-proof, while the M50 Mark II 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 M50 Mark II gets 305 shots out of its LP-E12 battery, while the A7R IV can take 670 images on a single charge of its 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 M50 Mark II was launched at a markedly lower price (by 83 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.
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 M50 Mark II 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 M50 Mark II (24MP), but the A7R IV nevertheless has marginally larger individual pixels (pixel pitch of 3.76μm versus 3.72μm for the M50 Mark II) due to its larger sensor. However, the M50 Mark II is a somewhat more recent model (by 1 year and 2 months) than the A7R IV, and its sensor might have benefitted from technological advances during this time that 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 M50 Mark II 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 M50 Mark II, 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 M50 Mark II 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 Sony Alpha A7R IV are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.
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. 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 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 A7R IV provides a faster frame rate than the M50 Mark II. It can shoot movie footage at 4K/30p, while the Canon is limited to 4K/24p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A7R IV offers a substantially higher resolution than the one in the M50 Mark II (5760k vs 2360k dots). The table below summarizes some of the other core capabilities of the Canon M50 Mark II and Sony A7R IV in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The M50 Mark II has one, while the A7R IV does not. While the built-in flash of the M50 Mark II is not very powerful, it can at times be useful as a fill-in light.The M50 Mark II 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, 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 M50 Mark II and the Sony A7R 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.
Concerning the storage of imaging data, both the M50 Mark II 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 M50 Mark II only has one slot. The A7R IV supports UHS-II cards (on both slots), while the M50 Mark II can use UHS-I cards.
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 M50 Mark II and Sony Alpha A7R IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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 M50 Mark II lacks such a headphone port.
Studio photographers will appreciate that the Sony A7R IV (unlike the M50 Mark II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the M50 Mark II and the A7R IV are recent models that are part of the current product line-up. The A7R IV replaced the earlier Sony A7R III, while the M50 Mark II followed on from the Canon M50. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.

If the count of relative strengths (bullet points above) is taken as a measure, the A7R IV is the clear winner of the contest (22 : 8 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 M50 Mark II 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 M50 Mark II and the A7R IV in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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], 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
