Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M-E (Typ 240) and the Leica M10-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

An illustration of the physical size and weight of the Leica M-E Typ 240 and the Leica M10-R is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The M10-R can be obtained in two different colors (black, silver), while the M-E Typ 240 is only available in silver.

In this particular case, the Leica M-E Typ 240 and the Leica M10-R have exactly the same width and height, and, thus, have identically-sized bodies. However, the M10-R is slightly lighter (3 percent) than the M-E Typ 240. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Leica M Lens Catalog.

Concerning battery life, the M-E Typ 240 gets 500 shots out of its Leica BP-SCL2 battery, while the M10-R can take 210 images on a single charge of its Leica BP-SCL5 power pack.

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 M-E Typ 240 was launched at a markedly lower price (by 52 percent) than the M10-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.

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.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

While the two cameras under review share the same sensor size, the M10-R offers a higher resolution of 40.9 megapixels, compared with 23.7 MP of the M-E Typ 240. This megapixels advantage translates into a 32 percent gain in linear resolution. On the other hand, these sensor specs imply that the M10-R has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.57μm versus 6.01μm for the M-E Typ 240). However, it should be noted that the M10-R is a somewhat more recent model (by 1 year) than the M-E Typ 240, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the M10-R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica M10-R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10-R for good quality output (200 dots per inch) amounts to 39.3 x 26 inches or 99.9 x 66 cm, for very good quality (250 dpi) 31.5 x 20.8 inches or 79.9 x 52.8 cm, and for excellent quality (300 dpi) 26.2 x 17.3 inches or 66.6 x 44 cm. The corresponding values for the Leica M-E Typ 240 are 29.8 x 19.9 inches or 75.6 x 50.5 cm for good quality, 23.8 x 15.9 inches or 60.5 x 40.4 cm for very good quality, and 19.8 x 13.3 inches or 50.4 x 33.7 cm for excellent quality prints.

The Leica M-E (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 Leica M10-R 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 M-E Typ 240 indeed provides movie recording capabilities, while the M10-R does not. The highest resolution format that the M-E Typ 240 can use is 1080/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The M-E Typ 240 and the M10-R are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the M10-R has a higher magnification than the one of the M-E Typ 240 (0.73x vs 0.68x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Leica M-E Typ 240, the Leica M10-R, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M10-R has a touchscreen, while the M-E Typ 240 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Leica M10-R 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-E Typ 240 and the M10-R write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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-E (Typ 240) and Leica M10-R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M10-R offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the M-E Typ 240 does not provide wifi capability.

Both the M-E Typ 240 and the M10-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 Leica. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica website.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Leica M-E Typ 240 and the Leica M10-R? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Leica M-E (Typ 240):

• 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 1080/25p movies.
• Longer lasting: Can take more shots (500 versus 210) on a single battery charge.
• More affordable: Was introduced into a lower priced category (52 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in June 2019).

Reasons to prefer the Leica M10-R:

• More detail: Has more megapixels (40.9 vs 23.7MP), which boosts linear resolution by 32%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.68x).
• More detailed LCD: Has a higher resolution rear screen (1037k vs 920k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (4.5 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More modern: Was introduced somewhat (1 year) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the M10-R is the clear winner of the contest (9 : 5 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 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 M-E Typ 240 and the M10-R 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.
