Canon 77D vs Leica SL
The Canon EOS 77D and the Leica SL (Typ 601) are two digital cameras that were announced, respectively, in February 2017 and October 2015. The 77D is a DSLR, while the SL is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (77D) 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 77D 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 side-by-side display below illustrates the physical size and weight of the Canon 77D and the Leica SL. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size 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 SL is notably larger (17 percent) than the Canon 77D. Moreover, the SL is substantially heavier (57 percent) than the 77D. It is noteworthy in this context that the SL is splash and dust-proof, while the 77D 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 77D was launched at a markedly lower price (by 88 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 77D 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.
In terms of underlying technology, both cameras are build around CMOS 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 77D), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the 77D is a somewhat more recent model (by 1 year and 3 months) than the SL, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. 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 77D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 77D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Leica SL (Typ 601) are ISO 50 to ISO 50000 (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"). Of the two cameras under consideration, the SL has a markedly higher DXO score than the 77D (overall score 10 points higher), which will translate into better image quality. The advantage is based on 1.4 bits higher color depth, 0.1 EV in additional dynamic range, and 0.9 stops in additional low light sensitivity. 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 are not only capable of taking still images, but can also record movies. 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 77D. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the SL has an electronic viewfinder (4400k dots), while the 77D 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 77D (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 adjacent table lists some of the other core features of the Canon 77D and Leica SL along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 77D has one, while the SL does not. While the built-in flash of the 77D is not very powerful, it can at times be useful as a fill-in light.The 77D 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 Canon 77D and the Leica SL 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 77D 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 77D only has one slot. The SL supports UHS-II cards (on its first slot), while the 77D 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 77D 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 77D lacks such a headphone port.
Studio photographers will appreciate that the Leica SL (unlike the 77D) 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.
The 77D is a recent model that features in the current product line-up of Canon. In contrast, the SL has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the SL was succeeded 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 how do things add up? Which of the two cameras – the Canon 77D or the Leica SL – 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.

- More heavily discounted: Has been on the market for longer (launched in October 2015).
If the count of individual advantages (bullet points above) is taken as a guide, the SL is the clear winner of the contest (22 : 13 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.

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 77D or the SL. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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 assessments were made in relation to similar cameras of the same technological generation. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
