Leica CL vs S2
The Leica CL (Typ 7323) and the Leica S2 are two digital cameras that were officially introduced, respectively, in November 2017 and September 2008. The CL is a mirrorless interchangeable lens camera, while the S2 is a DSLR. The cameras are based on an APS-C (CL) and a medium format (S2) sensor. The CL has a resolution of 24.1 megapixels, whereas the S2 provides 37.5 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 CL (Typ 7323) and the Leica S2? 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.
The side-by-side display below illustrates the physical size and weight of the Leica CL and the Leica S2. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica S2 is considerably larger (88 percent) than the Leica CL. Moreover, the S2 is substantially heavier (250 percent) than the CL. It is noteworthy in this context that the S2 is splash and dust-proof, while the CL 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. 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.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The CL was launched at a markedly lower price (by 88 percent) than the S2, 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.
The size of the imaging sensor is a crucial determinant 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 CL features an APS-C sensor and the Leica S2 a medium format sensor. The sensor area in the S2 is 264 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 0.8. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 37.5MP, the S2 offers a higher resolution than the CL (24.1MP), but the S2 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 3.92μm for the CL) due to its larger sensor. However, the CL is a much more recent model (by 9 years and 2 months) than the S2, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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 S2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S2 for good quality output (200 dots per inch) amounts to 37.5 x 25 inch or 95.3 x 63.5 cm, for very good quality (250 dpi) 30 x 20 inch or 76.2 x 50.8 cm, and for excellent quality (300 dpi) 25 x 16.7 inch or 63.5 x 42.3 cm. The corresponding values for the Leica CL are 30.1 x 20.1 inch or 76.4 x 51 cm for good quality, 24.1 x 16.1 inch or 61.1 x 40.8 cm for very good quality, and 20 x 13.4 inch or 50.9 x 34 cm for excellent quality prints.
The Leica CL (Typ 7323) has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Leica S2 are ISO 80 to ISO 1250 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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 also of capturing video footage. The CL indeed provides movie recording capabilities, while the S2 does not. The highest resolution format that the CL can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the CL has an electronic viewfinder (2360k dots), while the S2 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 viewfinder in the CL offers a wider field of view (100%) than the one in the S2 (96%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the S2 has a higher magnification (0.86x vs 0.49x), 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 CL, the Leica S2, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The CL has a touchscreen, while the S2 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
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, the CL is one of those camera that have an additional 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 CL 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.
The CL writes its imaging data to SDXC cards, while the S2 uses Compact Flash or SDHC cards. The S2 features dual card slots, which can be very useful in case a memory card fails. In contrast, the CL only has one slot. The CL supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the S2 cannot take advantage of Ultra High Speed SD cards.
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 CL (Typ 7323) and Leica S2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the CL offers wifi support, while the S2 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Leica S2 (unlike the CL) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The CL is a recent model that features in the current product line-up of Leica. In contrast, the S2 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the S2 was succeeded by the Leica S Typ 006. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica website.
So what conclusions can be drawn? Which of the two cameras – the Leica CL or the Leica S2 – 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 CL (Typ 7323):
- Broader imaging potential: Can record not only still images but also 4K/30p movies.
- More framing info: Has an electronic viewfinder that displays shooting data.
- More complete view: Has a viewfinder with a larger field of view (100% vs 96%).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (10 vs 1.5 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (131x78mm vs 160x120mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 1007g or 71 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards.
- More affordable: Was introduced into a lower priced category (88 percent cheaper at launch).
- More modern: Reflects 9 years and 2 months of technical progress since the S2 launch.
Arguments in favor of the Leica S2:
- More detail: Has more megapixels (37.5 vs 24.1MP), which boosts linear resolution by 25%.
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.86x vs 0.49x).
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- 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.
- More heavily discounted: Has been around for much longer (launched in September 2008).
If the number of relative strengths (bullet points above) is taken as a guide, the CL is the clear winner of the match-up (16 : 7 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 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.
How about other alternatives? Do the specifications of the Leica CL and the Leica S2 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the CL or the S2. 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
