Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M11 (Typ 2416) and the Leica SL2-S? 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 Leica M11 and the Leica SL2-S. 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 dimensions are rounded to the nearest millimeter.

The M11 can be obtained in two different colors (black, silver), while the Leica SL2-S 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 Leica SL2-S is notably larger (40 percent) than the Leica M11. Moreover, the Leica SL2-S is substantially heavier (45 percent) than the M11. 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 M11 gets 700 shots out of its Leica BP-SCL7 battery, while the Leica SL2-S can take 510 images on a single charge of its Leica BP-SCL4 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient 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 naturally be influenced heavily by the price. 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 Leica SL2-S was launched at a markedly lower price (by 46 percent) than the M11, 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 more expensive and 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 M11 offers a higher resolution of 60.3 megapixels, compared with 24 MP of the Leica SL2-S. This megapixels advantage translates into a 59 percent gain in linear resolution. On the other hand, these sensor specs imply that the M11 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.79μm versus 6.00μm for the Leica SL2-S). In this context, it should be noted, however, that the M11 is a somewhat more recent model (by 1 year and 1 month) than the Leica SL2-S, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Leica M11 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M11 for good quality output (200 dots per inch) amounts to 47.6 x 31.6 inches or 121 x 80.4 cm, for very good quality (250 dpi) 38.1 x 25.3 inches or 96.8 x 64.3 cm, and for excellent quality (300 dpi) 31.8 x 21.1 inches or 80.7 x 53.6 cm. The corresponding values for the Leica SL2-S are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

Unlike the M11, the Leica SL2-S has the capacity to capture high quality composite images (96MP) 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 Leica M11 (Typ 2416) has a native sensitivity range from ISO 64 to ISO 50000. The corresponding ISO settings for the Leica SL2-S are ISO 100 to ISO 50000, with the possibility to increase the ISO range to 50-100000.

In terms of underlying technology, the M11 is build around a BSI-CMOS sensor, while the Leica SL2-S 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the M11 has a notably higher overall DXO score than the Leica SL2-S (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.1 bits higher color depth, 0.7 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The Leica SL2-S indeed provides for movie recording, while the M11 does not. The highest resolution format that the Leica SL2-S can use is 4K/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the Leica SL2-S has an electronic viewfinder (5760k dots), while the M11 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the Leica SL2-S has a higher magnification than the one of the M11 (0.78x vs 0.73x), 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 M11, the Leica SL2-S, and comparable cameras.

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

One feature that is present on the Leica SL2-S, but is missing on the M11 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 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, both cameras under consideration feature an 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 Leica M11 and the Leica SL2-S 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 M11 and the Leica SL2-S write their files to SDXC cards. The Leica SL2-S features dual card slots, which can be very useful in case a memory card fails. In contrast, the M11 only has one slot. Moreover, both cameras support UHS-II cards (Ultra High Speed data transfer of up to 312 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 M11 (Typ 2416) and Leica SL2-S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the M11 and the Leica SL2-S are recent models that are part of the current product line-up. The M11 replaced the earlier Leica M10, while the Leica SL2-S does not have a direct predecessor. Further information on the features and operation of the M11 and Leica SL2-S can be found, respectively, in the Leica M11 Manual (free pdf) or the online Leica SL2-S Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Leica M11 or the Leica SL2-S – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Leica M11 (Typ 2416):

• More detail: Offers more megapixels (60.3 vs 24MP) with a 59% higher linear resolution.
• Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• More detailed LCD: Has a higher resolution rear screen (2333k vs 2100k dots).
• More compact: Is smaller (139x80mm vs 146x107mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 291g or 31 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (700 versus 510) on a single battery charge.
• More modern: Is somewhat more recent (announced 1 year and 1 month after the Leica SL2-S).

Arguments in favor of the Leica SL2-S:

• High quality composites: Can combine several shots after pixel-shifting its sensor.
• Broader imaging potential: Can capture not only stills but also 4K/60p video.
• More framing info: Has an electronic viewfinder that displays shooting data.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.73x).
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (20 vs 4.5 flaps/sec) to capture the decisive moment.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More affordable: Was introduced into a lower priced category (46 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in December 2020).

If the number of relative strengths (bullet points above) is taken as a guide, the Leica SL2-S emerges as the winner of the match-up (12 : 10 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the M11 or the Leica SL2-S. 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 expert reviews are important. 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.

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.
