Going beyond this snapshot of core features and characteristics, what are the differences between the Leica SL2 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

An illustration of the physical size and weight of the Leica SL2 and the Leica SL2-S is provided in the side-by-side display below. 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.

In this particular case, the Leica SL2 and the Leica SL2-S have exactly the same width and height, and, thus, have identically-sized bodies. However, the Leica SL2-S is slightly lighter (2 percent) than the Leica SL2. 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.

The battery packs of both cameras can be charged via USB, 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. 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 somewhat lower price (by 18 percent) than the Leica SL2, which makes it more attractive for photographers on a tight budget. 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 imaging sensor is a crucial determinant 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 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 Leica SL2 offers a higher resolution of 46.7 megapixels, compared with 24 MP of the Leica SL2-S. This megapixels advantage translates into a 39 percent gain in linear resolution. On the other hand, these sensor specs imply that the Leica SL2 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.30μm versus 6.00μm for the Leica SL2-S). Moreover, it should be noted that the Leica SL2-S is a somewhat more recent model (by 1 year and 1 month) than the Leica SL2, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. 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 SL2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Leica SL2 for good quality output (200 dots per inch) amounts to 41.8 x 27.9 inches or 106.3 x 70.9 cm, for very good quality (250 dpi) 33.5 x 22.3 inches or 85 x 56.7 cm, and for excellent quality (300 dpi) 27.9 x 18.6 inches or 70.8 x 47.3 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.

Both cameras have the capacity to capture high quality composite images by combining multiple shots after shifting the sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Leica SL2 has a native sensitivity range from ISO 100 to ISO 50000, which can be extended to ISO 50-50000. 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.

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 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/60p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The Leica SL2 and the Leica SL2-S are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 5760k dots. The following table reports on some other key feature differences and similarities of the Leica SL2, the Leica SL2-S, and comparable cameras.

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

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 SL2 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 Leica SL2 and the Leica SL2-S write their files to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Moreover, both the Leica SL2 and the Leica SL2-S support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s, on both slots.

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 SL2 and Leica SL2-S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Leica SL2 (unlike the Leica SL2-S) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the Leica SL2 and the Leica SL2-S are recent models that are part of the current product line-up. The Leica SL2 replaced the earlier Leica SL (Typ 601), while the Leica SL2-S does not have a direct predecessor. Further information on the features and operation of the Leica SL2 and Leica SL2-S can be found, respectively, in the Leica SL2 Manual (free pdf) or the online Leica SL2-S Manual.

Review summary

So how do things add up? Is the Leica SL2 better than the Leica SL2-S or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Leica SL2:

• More detail: Offers more megapixels (46.7 vs 24MP) with a 40% higher linear resolution.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been on the market for longer (launched in November 2019).

Arguments in favor of the Leica SL2-S:

• Faster burst: Shoots at higher frequency (20 vs 10 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (510 versus 370) out of a single battery charge.
• Faster data transfer: Supports a more advanced USB protocol (3.2 vs 3.1).
• More affordable: Was released into a lower priced segment (18 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 1 month) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the Leica SL2-S emerges as the winner of the match-up (5 : 3 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.

How about other alternatives? Do the specifications of the Leica SL2 and the Leica SL2-S place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the Leica SL2 or the Leica SL2-S perform in practice. 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 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
