Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M (Typ 240) 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

The physical size and weight of the Leica M Typ 240 and the YI M1 are illustrated 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.

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 YI M1 is considerably smaller (34 percent) than the Leica M Typ 240. Moreover, the M1 is substantially lighter (59 percent) than the M Typ 240. It is worth mentioning in this context that the M Typ 240 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 Leica M Lens Catalog (M Typ 240) and the Micro Four Thirds Lens Catalog (M1).

Concerning battery life, the M Typ 240 gets 500 shots out of its Leica BP-SCL2 battery, while the M1 can take 450 images on a single charge of its YI BXM-10 power pack. The power pack in the M1 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. 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 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 95 percent) than the M Typ 240, 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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica M Typ 240 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 M Typ 240 has a native 3:2 aspect ratio, while the one in the M1 offers a 4:3 aspect.

With 23.7MP, the M Typ 240 offers a higher resolution than the M1 (20.2MP), but the M Typ 240 nevertheless has larger individual pixels (pixel pitch of 6.01μm versus 3.34μm for the M1) due to its larger sensor. However, the M1 is a much more recent model (by 4 years) than the M Typ 240, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Leica M Typ 240 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M Typ 240 for good quality output (200 dots per inch) amounts to 29.8 x 19.9 inches or 75.6 x 50.5 cm, for very good quality (250 dpi) 23.8 x 15.9 inches or 60.5 x 40.4 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inches or 50.4 x 33.7 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 Leica M (Typ 240) has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-6400. The corresponding ISO settings for the YI M1 are ISO 100 to ISO 25600 (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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the M1 provides a better video resolution than the M Typ 240. It can shoot movie footage at 4K/30p, while the Leica is limited to 1080/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the M Typ 240 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 table below summarizes some of the other core capabilities of the Leica M Typ 240 and YI M1 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M1 has a touchscreen, while the M Typ 240 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 M Typ 240 and the M1 write their files to SDXC cards. The M Typ 240 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 Leica M (Typ 240) 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 M1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the M Typ 240 does not provide wifi capability.

Both the M Typ 240 and the M1 have been discontinued, but can regularly be found used on ebay. The M Typ 240 was replaced by the Leica M Typ 262, while the M1 does not have a direct successor. Further information on the features and operation of the M Typ 240 and M1 can be found, respectively, in the Leica M Typ 240 Manual (free pdf) or the online YI M1 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Leica M Typ 240 and the YI M1? Which camera is better? The listing below highlights the relative strengths of the two models.

Advantages of the Leica M (Typ 240):

• More detail: Offers more megapixels (23.7 vs 20.2MP) with a 10% higher linear resolution.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Longer lasting: Can take more shots (500 versus 450) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• 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 price.
• More heavily discounted: Has been available for much longer (launched in September 2012).

Reasons to prefer the YI M1:

• Better video: Provides higher definition movie capture (4K/30p vs 1080/25p).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (114x64mm vs 139x80mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 399g or 59 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• 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 modern: Reflects 4 years of technical progress since the M Typ 240 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the M1 is the clear winner of the contest (12 : 7 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

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 M Typ 240 or the M1 perform in practice. 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 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
