Canon T6s vs Leica SL
The Canon EOS Rebel T6s (called Canon 760D in some regions) and the Leica SL (Typ 601) are two digital cameras that were announced, respectively, in February 2015 and October 2015. The T6s is a DSLR, while the SL is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (T6s) and a full frame (SL) sensor. Both cameras offer a resolution of 24 megapixels.
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 Canon EOS Rebel T6s 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 Canon T6s 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 measures 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 SL is notably larger (15 percent) than the Canon T6s. Moreover, the SL is substantially heavier (50 percent) than the T6s. It is noteworthy in this context that the SL is splash and dust-proof, while the T6s 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. 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.

Any camera decision will obviously take relative prices into account. 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 T6s was launched at a markedly lower price (by 91 percent) than the SL, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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. 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.
Of the two cameras under consideration, the Canon T6s features an APS-C sensor and the Leica SL a full frame sensor. The sensor area in the SL is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
Even though the SL has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the SL has a lower pixel density and larger individual pixels (with a pixel pitch of 6.00μm versus 3.72μm for the T6s), which gives it a potential advantage in terms of light gathering capacity. In addition, the SL is a somewhat more recent model (by 8 months) than the T6s, and its sensor might have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the SL has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The T6s has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel T6s has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Leica SL (Typ 601) are ISO 50 to ISO 50000 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the SL offers substantially better image quality than the T6s (overall score 18 points higher). The advantage is based on 2.4 bits higher color depth, 1.4 EV in additional dynamic range, and 1 stops in additional 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the SL provides a better video resolution than the T6s. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.
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 T6s 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 SL offers a wider field of view (100%) than the one in the T6s (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the SL has a higher magnification (0.80x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon T6s and Leica SL in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The T6s has one, while the SL does not. While the built-in flash of the T6s is not very powerful, it can at times be useful as a fill-in light.The T6s has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the SL does not have a selfie-screen.
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 T6s 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 T6s only has one slot. The SL supports UHS-II cards (on its first slot), while the T6s can use UHS-I 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 Canon EOS Rebel T6s 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 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The T6s lacks such a headphone port.
Studio photographers will appreciate that the Leica SL (unlike the T6s) 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 T6s and the SL have been discontinued, but can regularly be found used on eBay. The T6s was replaced by the Canon 77D, while the SL was followed by the Leica SL2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Leica websites.
So what is the bottom line? Is there a clear favorite between the Canon T6s and the Leica SL? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

- More modern: Was introduced somewhat (8 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the SL is the clear winner of the contest (24 : 11 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Canon T6s and the Leica SL place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 incomplete and does no justice, for example, to the way the T6s or the SL 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.
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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
