Leica M8 vs SL
The Leica M8 and the Leica SL (Typ 601) are two enthusiast cameras that were announced, respectively, in September 2006 and October 2015. The M8 is a rangefinder-focusing mirrorless, while the SL is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (M8) and a full frame (SL) sensor. The M8 has a resolution of 10.4 megapixels, whereas the SL provides 24 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 M8 and the Leica SL (Typ 601)? 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 physical size and weight of the Leica M8 and the Leica SL are illustrated 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 M8 can be obtained in two different colors (black, silver), while the SL 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 SL is notably larger (37 percent) than the Leica M8. Moreover, the SL is substantially heavier (43 percent) than the M8. It is noteworthy in this context that the SL is splash and dust-proof, while the M8 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. 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 M8 was launched at a markedly lower price (by 26 percent) than the SL, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.
Of the two cameras under consideration, the Leica M8 features an APS-H sensor and the Leica SL a full frame sensor. The sensor area in the SL is 78 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the SL offers a higher resolution than the M8 (10.4MP), but the SL has smaller individual pixels (pixel pitch of 6.00μm versus 6.84μm for the M8). Yet, the SL is a much more recent model (by 9 years and 1 month) than the M8, 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 SL implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SL for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Leica M8 are 19.7 x 13.2 inches or 50 x 33.4 cm for good quality, 15.7 x 10.5 inches or 40 x 26.7 cm for very good quality, and 13.1 x 8.8 inches or 33.3 x 22.3 cm for excellent quality prints.
The Leica M8 has a native sensitivity range from ISO 160 to ISO 2500. The corresponding ISO settings for the Leica SL (Typ 601) are ISO 50 to ISO 50000 (no boost).
In terms of underlying technology, the M8 is build around a CCD sensor, while the SL 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.
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"). Of the two cameras under consideration, the SL offers substantially better image quality than the M8 (overall score 29 points higher). The advantage is based on 3.9 bits higher color depth, 2.1 EV in additional dynamic range, and 1.5 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The SL indeed provides for movie recording, while the M8 does not. The highest resolution format that the SL can use is 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the SL has an electronic viewfinder (4400k dots), while the M8 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 adjacent table lists some of the other core features of the Leica M8 and Leica SL along with similar information for a selection of comparators.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The SL has a touchscreen, while the M8 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 SL 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 SL 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 M8 and the SL write their files to SDXC cards. The SL features dual card slots, which can be very useful in case a memory card fails. In contrast, the M8 only has one slot. The SL supports UHS-II cards on its first slot and UHS-I on its second one, while the M8 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 M8 and Leica SL (Typ 601) and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SL offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the M8 does not provide wifi capability.
Studio photographers will appreciate that the Leica SL (unlike the M8) 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 SL has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the M8 and the SL have been discontinued, but can regularly be found used on ebay. The M8 was replaced by the Leica M9, while the SL was followed by the Leica SL2. Further information on the features and operation of the M8 and SL can be found, respectively, in the Leica M8 Manual (free pdf) or the online Leica SL Manual.
So what is the bottom line? Which of the two cameras – the Leica M8 or the Leica SL – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Leica M8:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- More compact: Is smaller (139x80mm vs 147x104mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 256g or 30 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (26 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in September 2006).
Advantages of the Leica SL (Typ 601):
- More detail: Has more megapixels (24 vs 10.4MP), which boosts linear resolution by 52%.
- Better image quality: Scores substantially higher (29 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (3.9 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (2.1 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.5 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 4K/30p video.
- More framing info: Has an electronic viewfinder that displays shooting data.
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (11 vs 2 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.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- 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 Ultra High Speed (UHS-II and UHS-I) SDXC cards.
- More modern: Reflects 9 years and 1 month of technical progress since the M8 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the SL is the clear winner of the contest (22 : 5 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.
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 M8 or the SL perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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 ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
