Canon R vs Leica SL2-S
The Canon EOS R and the Leica SL2-S are two digital cameras that were officially introduced, respectively, in September 2018 and December 2020. Both the Canon R and the SL2-S are mirrorless interchangeable lens cameras that are equipped with a full frame sensor. The Canon has a resolution of 30.1 megapixels, whereas the Leica 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 Canon EOS R and the Leica SL2-S? 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 R and the Leica SL2-S. 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 SL2-S is notably larger (15 percent) than the Canon R. Moreover, the SL2-S is substantially heavier (41 percent) than the Canon R. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
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 battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 Canon R was launched at a markedly lower price (by 53 percent) than the SL2-S, 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. 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.
While the two cameras under review share the same sensor size, the Canon R offers a higher resolution of 30.1 megapixels, compared with 24 MP of the SL2-S. This megapixels advantage translates into a 12 percent gain in linear resolution. On the other hand, these sensor specs imply that the Canon R has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.36μm versus 6.00μm for the SL2-S). Moreover, it should be noted that the SL2-S is much more recent (by 2 years and 3 months) than the Canon R, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. Coming back to sensor resolution, it should be mentioned that the SL2-S has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Canon R for good quality output (200 dots per inch) amounts to 33.6 x 22.4 inches or 85.3 x 56.9 cm, for very good quality (250 dpi) 26.9 x 17.9 inches or 68.3 x 45.5 cm, and for excellent quality (300 dpi) 22.4 x 14.9 inches or 56.9 x 37.9 cm. The corresponding values for the Leica SL2-S are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.
The Canon R has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the Canon R, the SL2-S has the capacity to capture high quality composite images (96MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Canon EOS R has a native sensitivity range from ISO 100 to ISO 40000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Leica SL2-S are ISO 100 to ISO 50000, with the possibility to increase the ISO range to 50-100000.
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"). 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the SL2-S provides a faster frame rate than the Canon R. It can shoot movie footage at 4K/60p, while the Canon is limited to 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the SL2-S offers a substantially higher resolution than the one in the Canon R (5760k vs 3690k dots). The adjacent table lists some of the other core features of the Canon R and Leica SL2-S along with similar information for a selection of comparators.

One feature that differentiates the SL2-S and the Canon R is in-body image stabilization (IBIS). The SL2-S reduces the risk of handshake-induced blur with all attached lenses, while the Canon R offers no blur reduction with lenses that themselves do not provide optical image stabilization.The Canon R 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 SL2-S 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, both cameras under consideration feature an 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 SL2-S 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 Canon R and the SL2-S write their files to SDXC cards. The SL2-S features dual card slots, which can be very useful in case a memory card fails. In contrast, the Canon R only has one slot. Moreover, both cameras support UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s).
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 R and Leica SL2-S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the Canon R and the SL2-S are recent models that are part of the current product line-up. Neither of the two has a direct predecessor, so perhaps they will constitute the origins of new camera lines for Canon and Leica. 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? Is there a clear favorite between the Canon R and the Leica SL2-S? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Canon EOS R:
- More detail: Offers more megapixels (30.1 vs 24MP) with a 12% higher linear resolution.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- More compact: Is smaller (139x98mm vs 146x107mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 271g or 29 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (53 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in September 2018).
Advantages of the Leica SL2-S:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 3690k dots).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.76x).
- Faster burst: Shoots at higher frequency (20 vs 8 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Gets more shots (510 versus 370) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Faster data transfer: Supports a more advanced USB protocol (3.2 vs 3.1).
- More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
- More modern: Reflects 2 years and 3 months of technical progress since the Canon R launch.
If the count of individual advantages (bullet points above) is taken as a guide, the SL2-S is the clear winner of the contest (14 : 9 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 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.
How about other alternatives? Do the specifications of the Canon R and the Leica SL2-S place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the Canon R or the SL2-S 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], 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 above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
