Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha A7R V and the YI M1? 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 Sony A7R V and the YI M1 is provided in the side-by-side display below. 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 width, height and depth measures are rounded to the nearest millimeter.

The M1 can be obtained in two different colors (black, silver), while the A7R V 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 YI M1 is considerably smaller (43 percent) than the Sony A7R V. Moreover, the M1 is substantially lighter (61 percent) than the A7R V. It is worth mentioning in this context that the A7R V is splash and dust resistant, 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Sony FE Lens Catalog (A7R V) and the Micro Four Thirds Lens Catalog (M1). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the A7R V gets 530 shots out of its Sony NP-FZ100 battery, while the M1 can take 450 images on a single charge of its YI BXM-10 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The M1 was launched at a markedly lower price (by 91 percent) than the A7R V, 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 size of the imaging sensor is a crucial determinant 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. 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 Sony A7R V features a full frame sensor and the YI M1 a Four Thirds sensor. The sensor area in the M1 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 A7R V has a native 3:2 aspect ratio, while the one in the M1 offers a 4:3 aspect.

With 60.2MP, the A7R V offers a higher resolution than the M1 (20.2MP), but the A7R V nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 3.34μm for the M1) due to its larger sensor. Moreover, the A7R V is a much more recent model (by 6 years and 1 month) than the M1, and its sensor will 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 A7R V has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A7R V implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R V 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 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 A7R V has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the M1, the A7R V has the capacity to capture high quality composite images (240MP) 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 Sony Alpha A7R V has a native sensitivity range from ISO 100 to ISO 32000, which can be extended to ISO 50-102400. The corresponding ISO settings for the YI M1 are ISO 100 to ISO 25600 (no boost).

In terms of underlying technology, the A7R V is build around a BSI-CMOS sensor, while the M1 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 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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7R V provides a higher video resolution than the M1. It can shoot video footage at 8k/24p, while the YI is limited to 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7R V has an electronic viewfinder (9440k 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 following table reports on some other key feature differences and similarities of the Sony A7R V, the YI M1, and comparable cameras.

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

One feature that differentiates the A7R V and the M1 is in-body image stabilization (IBIS). The A7R V reduces the risk of handshake-induced blur with all attached lenses, while the M1 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

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 V 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 V and the YI M1 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 A7R V writes its imaging data to CFexpress (type A) or SDXC cards, while the M1 uses SDXC cards. The A7R V features dual card slots, which can be very useful in case a memory card fails. In contrast, the M1 only has one slot. The A7R V 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 Sony Alpha A7R V and YI M1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R V has a microphone port, which is missing on the M1. 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 Sony A7R V (unlike the M1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The A7R V is a recent model that features in the current product line-up of Sony. In contrast, the M1 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the M1 from YI. Further information on the features and operation of the A7R V and M1 can be found, respectively, in the Sony A7R V Manual (free pdf) or the online YI M1 Manual.

Review summary

So what is the bottom line? Is the Sony A7R V better than the YI M1 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Sony Alpha A7R V:

• More detail: Offers more megapixels (60.2 vs 20.2MP) with a 76% higher linear resolution.
• 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: Features a larger and more technologically advanced imaging 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.
• 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 full-flex 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 (10 vs 5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Longer lasting: Can take more shots (530 versus 450) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.

• Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards.
• More modern: Reflects 6 years and 1 month of technical progress since the M1 launch.

Arguments in favor of the YI M1:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More compact: Is smaller (114x64mm vs 131x97mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 442g or 61 percent) and is thus easier to take along.
• More affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in September 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the A7R V is the clear winner of the match-up (28 : 5 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 Sony A7R V and the YI M1 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 says little about, for example, the shooting experience and imaging performance of the A7R V and the M1 in practical situations. 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 why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
