The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Leica SL was launched in the US market at a price of $7,450. 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 with a 35mm slide
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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
The Leica SL features a full frame sensor and has a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the Leica SL among the large-sensor cameras that aim for top notch image quality.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 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 also of capturing video footage. The SL indeed provides movie recording capabilities. The highest resolution format that the SL can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the SL has an electronic viewfinder with a resolution of 4400k dots. The viewfinder offers a field of view of 100% and a magnification of 0.80x. The adjacent tables list some of the other core features of the Leica SL along with similar information for a selection of comparators.

One useful feature of the SL is a presence of 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.
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 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 has a microphone port. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
While the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the SL in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
Leica SL FAQ
Below are some additional questions and answers concerning some particular features of the SL.
What is the technology behind the imaging sensor in the SL?
The camera has a CMOS (Complementary Metal–Oxide–Semiconductor) sensor at its core.
Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?
Leica equipped the SL with the Maestro II image processor.
What is the ISO sensitivity range of the SL?
The camera has a native sensitivity range from ISO 50 to ISO 50000.
What is the life expectancy of the shutter in the Leica SL (Typ 601)?
Leica does not publish a shutter rating for the SL. Yet, shutters in comparable cameras from other manufacturers are said to be good for at least 100 000 actuations. It should be noted, though, that this number represents a Mean Time before Failure. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust an expected shutter life of 100 000 shots over, say, three years, one would have to take about 100 pictures each and every day.
Is completely silent shooting possible with the Leica SL?
The camera has an electronic shutter option, so that it is indeed feasible to capture images without any shutter noise.
Do I need to purchase an external camera trigger to shoot time-lapse sequences?
No, the Leica SL (Typ 601) has an intervalometer built-in, so that low frequency shooting (for example, flower blooming, sunset, moon rise) can be undertaken without the need to purchase a separate external intervalometer and related software.
Is it difficult to use manual focus lenses with the Leica SL?
The SL offers focus peaking as a manual focus aid. This feature works by placing a colored highlight on in-focus zones within the image.
What is the fastest shutter speed that can be used with flash?
The SL's flash sync speed is 1/250 sec.
Does the Leica SL support the Ultra High Speed (UHS) bus interface for SD cards?
Yes, the camera can indeed use UHS-II cards (data transfer speed of up to 312 MB/s) in its first slot, and UHS-I cards (up to 104 MB/s) in its second slot.
Which battery does the SL use?
The camera gets its power from the BP-SCL4, which is a rechargeable Lithium-Ion power pack.
Is there a vertical grip available for the SL?
Yes, Leica offers the HG-SCL4 as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.
Does the Leica SL (Typ 601) support geotagging?
The SL has a built-in GPS (Global Positioning System) module and can embed location information in the EXIF data of the captured image.
