Canon 250D vs Leica SL2-S
The Canon EOS 250D (called Canon SL3 in some regions) and the Leica SL2-S are two digital cameras that were officially introduced, respectively, in April 2019 and December 2020. The 250D is a DSLR, while the SL2-S is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (250D) and a full frame (SL2-S) 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 250D 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 250D and the Leica SL2-S. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The 250D can be obtained in two different colors (black, white), while the SL2-S 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 SL2-S is notably larger (38 percent) than the Canon 250D. Moreover, the SL2-S is substantially heavier (107 percent) than the 250D. It is noteworthy in this context that the SL2-S is splash and dust-proof, while the 250D 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 power pack in the SL2-S can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 naturally be influenced heavily by the price. 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 250D was launched at a markedly lower price (by 88 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 250D features an APS-C sensor and the Leica SL2-S a full frame sensor. The sensor area in the SL2-S 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.
Even though the SL2-S has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the SL2-S has a lower pixel density and larger individual pixels (with a pixel pitch of 6.00μm versus 3.72μm for the 250D), which gives it a potential advantage in terms of light gathering capacity. In addition, the SL2-S is a somewhat more recent model (by 1 year and 8 months) than the 250D, and its sensor might have benefitted from technological advances during this time. 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 250D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the 250D, 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 250D 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 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 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 SL2-S provides a faster frame rate than the 250D. It can shoot movie footage at 4K/60p, while the Canon is limited to 4K/25p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the SL2-S has an electronic viewfinder (5760k dots), while the 250D 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 SL2-S offers a wider field of view (100%) than the one in the 250D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the SL2-S has a higher magnification (0.78x vs 0.54x), 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 250D and Leica SL2-S 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 250D has one, while the SL2-S does not. While the built-in flash of the 250D is not very powerful, it can at times be useful as a fill-in light.The 250D 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, the SL2-S 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 250D and the Leica SL2-S 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 250D 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 250D only has one slot. The SL2-S supports UHS-II cards (on both slots), while the 250D 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 250D and Leica SL2-S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SL2-S has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The 250D lacks such a headphone port.
Both the 250D and the SL2-S are recent models that are part of the current product line-up. The 250D replaced the earlier Canon 200D, while the SL2-S does not have a direct predecessor. 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 250D and the Leica SL2-S? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

If the count of individual advantages (bullet points above) is taken as a guide, the SL2-S is the clear winner of the contest (27 : 11 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the 250D and the SL2-S in practical situations. 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 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 above review scores should be interpreted 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
