Leica M-E Typ 240 vs S3

The Leica M-E (Typ 240) and the Leica S3 are two digital cameras that were announced, respectively, in June 2019 and September 2018. The M-E Typ 240 is a rangefinder-focusing mirrorless camera, while the S3 is a DSLR. The cameras are based on a full frame (M-E Typ 240) and a medium format (S3) sensor. The M-E Typ 240 has a resolution of 23.7 megapixels, whereas the S3 provides 64 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 Leica M-E (Typ 240) and the Leica S3? 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-E Typ 240 and the Leica S3 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica S3 is considerably larger (73 percent) than the Leica M-E Typ 240. Moreover, the S3 is substantially heavier (85 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. 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 M-E Typ 240 gets 500 shots out of its Leica BP-SCL2 battery, while the S3 can take .. images on a single charge of its Leica BP-PRO1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. 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 79 percent) than the S3, 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Leica M-E Typ 240 features a full frame sensor and the Leica S3 a medium format sensor. The sensor area in the S3 is 58 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 0.8. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 64MP, the S3 offers a higher resolution than the M-E Typ 240 (23.7MP), but the S3 has smaller individual pixels (pixel pitch of 4.59μm versus 6.01μm for the M-E Typ 240). It is noteworthy in this context that the M-E Typ 240 is a somewhat more recent model (by 8 months) than the S3, 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 S3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica S3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S3 for good quality output (200 dots per inch) amounts to 49 x 32.7 inches or 124.5 x 83 cm, for very good quality (250 dpi) 39.2 x 26.1 inches or 99.6 x 66.4 cm, and for excellent quality (300 dpi) 32.7 x 21.8 inches or 83 x 55.3 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 S3 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.

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 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 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, but the S3 provides a better video resolution than the M-E Typ 240. It can shoot movie footage at 4K/24p, while the M-E Typ 240 is limited to 1080/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The M-E Typ 240 and the S3 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 viewfinder in the M-E Typ 240 offers a wider field of view (100%) than the one in the S3 (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the S3 has a higher magnification (0.87x vs 0.68x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Leica M-E Typ 240 and Leica S3 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the S3, but is missing on the M-E Typ 240 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 M-E Typ 240 writes its imaging data to SDXC cards, while the S3 uses Compact Flash or SDXC cards. The S3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the M-E Typ 240 only has one slot. The S3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the M-E Typ 240 can use UHS-I cards (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 S3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S3 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.

Studio photographers will appreciate that the Leica S3 (unlike the M-E Typ 240) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the S3 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the M-E Typ 240 and the S3 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? Which of the two cameras – the Leica M-E Typ 240 or the Leica S3 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Leica M-E (Typ 240):

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
• More compact: Is smaller (139x80mm vs 160x120mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 580g or 46 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (79 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 8 months after the S3).

Advantages of the Leica S3:

• More detail: Has more megapixels (64 vs 23.7MP), which boosts linear resolution by 65%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher definition movie capture (4K/24p vs 1080/25p).
• 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.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.87x vs 0.68x).
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More heavily discounted: Has been on the market for longer (launched in September 2018).

If the count of relative strengths (bullet points above) is taken as a measure, the S3 is the clear winner of the contest (14 : 6 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the M-E Typ 240 or the S3. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

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.

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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
