YI M1 vs Canon R

The YI M1 and the Canon EOS R are two digital cameras that were announced, respectively, in September 2016 and September 2018. Both the M1 and the Canon R are mirrorless interchangeable lens cameras that are based on a Four Thirds (M1) and a full frame (Canon R) sensor. The YI has a resolution of 20.2 megapixels, whereas the Canon provides 30.1 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 YI M1 and the Canon EOS R? 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 YI M1 and the Canon R. 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 measures are rounded to the nearest millimeter.

The M1 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 Canon R is considerably larger (87 percent) than the YI M1. Moreover, the Canon R is substantially heavier (135 percent) than the M1. It is noteworthy in this context that the Canon R is splash and dust-proof, while the M1 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 M1 gets 450 shots out of its YI BXM-10 battery, while the Canon R can take 370 images on a single charge of its Canon LP-E6N power pack. 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.

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 M1 was launched at a markedly lower price (by 85 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.

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 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the YI M1 features a Four Thirds sensor and the Canon R a full frame sensor. The sensor area in the Canon R is 284 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the M1 has a native 4:3 aspect ratio, while the one in the Canon R offers a 3:2 aspect.

With 30.1MP, the Canon R offers a higher resolution than the M1 (20.2MP), but the Canon R nevertheless has larger individual pixels (pixel pitch of 5.36μm versus 3.34μm for the M1) due to its larger sensor. Moreover, the Canon R is a somewhat more recent model (by 1 year and 11 months) than the M1, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

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 YI M1 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 Canon R has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The YI M1 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Canon EOS R are ISO 100 to ISO 40000, with the possibility to increase the ISO range to 50-102400.

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.

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. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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, and both provide the same movie specifications (4K/30p).

Feature comparison

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 M1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the YI M1 and Canon R in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the Canon R, but is missing on the M1 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.

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 YI M1 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 M1 and the Canon R 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 M1 cannot take advantage of Ultra High Speed SD 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. The table below provides an overview of the connectivity of the YI M1 and Canon EOS R 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 headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The M1 lacks such a headphone port.

Both the M1 and the Canon R have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from YI and Canon. Further information on the features and operation of the M1 and Canon R can be found, respectively, in the YI M1 Manual (free pdf) or the online Canon R Manual.

Review summary

So how do things add up? Is there a clear favorite between the YI M1 and the Canon R? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the YI M1:

• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (114x64mm vs 139x98mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 379g or 57 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (450 versus 370) on a single battery charge.
• More affordable: Was introduced into a lower priced category (85 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in September 2016).

Advantages of the Canon EOS R:

• More detail: Has more megapixels (30.1 vs 20.2MP), which boosts linear resolution by 25%.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• 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.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (2100k vs 1040k 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.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
• Faster buffer clearing: Has an SD card interface that supports the UHS-II standard.
• More modern: Was introduced somewhat (1 year and 11 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the Canon R is the clear winner of the contest (21 : 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 YI M1 and the Canon R 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the M1 or the Canon R 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
