Going beyond this snapshot of core features and characteristics, what are the differences between the YI M1 and the Leica M10 (Typ 3656)? 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 Leica M10. 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.

Both cameras are available in two different colors (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica M10 is considerably larger (52 percent) than the YI M1. Moreover, the M10 is substantially heavier (135 percent) than the M1. It is noteworthy in this context that the M10 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. 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 Micro Four Thirds Lens Catalog (M1) and the Leica M Lens Catalog (M10).

Concerning battery life, the M1 gets 450 shots out of its YI BXM-10 battery, while the M10 can take 210 images on a single charge of its Leica BP-SCL5 power pack. The power pack in the M1 can be charged via the USB port, so that it is not always necessary to take the battery charger along 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 95 percent) than the M10, 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 size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the YI M1 features a Four Thirds sensor and the Leica M10 a full frame sensor. The sensor area in the M10 is 280 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 M10 offers a 3:2 aspect.

With 23.8MP, the M10 offers a higher resolution than the M1 (20.2MP), but the M10 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 3.34μm for the M1) due to its larger sensor. Moreover, the M10 is a somewhat more recent model (by 3 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. Coming back to sensor resolution, it should be mentioned that the M10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica M10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10 for good quality output (200 dots per inch) amounts to 29.8 x 20 inches or 75.6 x 50.7 cm, for very good quality (250 dpi) 23.8 x 16 inches or 60.5 x 40.6 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inches or 50.4 x 33.8 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 YI M1 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Leica M10 (Typ 3656) are ISO 100 to ISO 50000 (no boost).

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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 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. The M1 indeed provides movie recording capabilities, while the M10 does not. The highest resolution format that the M1 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the M10 has an optical viewfinder, which can be very useful 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 YI M1, the Leica M10, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M1 has a touchscreen, while the M10 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The YI M1 and the Leica M10 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 M1 and the M10 write their files to SDXC cards. The M10 supports UHS-I cards (Ultra High Speed data transfer of up to 104 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 Leica M10 (Typ 3656) and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the M1 and the M10 have been discontinued, but can regularly be found used on ebay. The M10 was replaced by the Leica M11, while the M1 does not have a direct successor. Further information on the features and operation of the M1 and M10 can be found, respectively, in the YI M1 Manual (free pdf) or the online Leica M10 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the YI M1 and the Leica M10? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the YI M1:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Broader imaging potential: Can record not only still images but also 4K/30p movies.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More compact: Is smaller (114x64mm vs 139x80mm) 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 210) on a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (95 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in September 2016).

Reasons to prefer the Leica M10 (Typ 3656):

• More detail: Has more megapixels (23.8 vs 20.2MP), which boosts linear resolution by 11%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More modern: Was introduced somewhat (3 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the M10 comes out slightly ahead of the M1 (11 : 10 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.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the M1 and the M10 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 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.

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.
