Canon T2i vs Leica S2
The Canon EOS Rebel T2i (called Canon 550D in some regions) and the Leica S2 are two digital cameras that were revealed to the public, respectively, in February 2010 and September 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T2i) and a medium format (S2) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Leica provides 37.5 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 Rebel T2i and the Leica S2? 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.
An illustration of the physical size and weight of the Canon T2i and the Leica S2 is provided in the side-by-side display below. 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 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 S2 is considerably larger (52 percent) than the Canon T2i. Moreover, the S2 is substantially heavier (166 percent) than the T2i. It is noteworthy in this context that the S2 is splash and dust-proof, while the T2i 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.

The price is, of course, an important factor in any camera decision. 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 T2i was launched at a markedly lower price (by 97 percent) than the S2, 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 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 T2i features an APS-C sensor and the Leica S2 a medium format sensor. The sensor area in the S2 is 307 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 0.8. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 37.5MP, the S2 offers a higher resolution than the T2i (17.9MP), but the S2 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 4.31μm for the T2i) due to its larger sensor. However, the T2i is a somewhat more recent model (by 1 year and 4 months) than the S2, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the S2 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Leica S2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S2 for good quality output (200 dots per inch) amounts to 37.5 x 25 inches or 95.3 x 63.5 cm, for very good quality (250 dpi) 30 x 20 inches or 76.2 x 50.8 cm, and for excellent quality (300 dpi) 25 x 16.7 inches or 63.5 x 42.3 cm. The corresponding values for the Canon T2i are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.
The Canon EOS Rebel T2i has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Leica S2 are ISO 80 to ISO 1250 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). 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 cannot only take still pictures, but also record videos. The T2i indeed provides movie recording capabilities, while the S2 does not. The highest resolution format that the T2i can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The T2i and the S2 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the S2 offers a wider field of view (96%) than the one in the T2i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the S2 has a higher magnification (0.86x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon T2i, the Leica S2, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The T2i has one, while the S2 does not. While the built-in flash of the T2i is not very powerful, it can at times be useful as a fill-in light.
The T2i writes its imaging data to SDXC cards, while the S2 uses Compact Flash or SDHC cards. The S2 features dual card slots, which can be very useful in case a memory card fails. In contrast, the T2i only has one slot.
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 T2i and Leica S2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Leica S2 (unlike the T2i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the T2i and the S2 have been discontinued, but can regularly be found used on eBay. The S2 was replaced by the Leica S Typ 006, while the T2i was followed by the Canon T3i. 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 the Canon T2i better than the Leica S2 or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS Rebel T2i:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
- Faster burst: Shoots at higher frequency (3.7 vs 1.5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (129x98mm vs 160x120mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 880g or 62 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (97 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 1 year and 4 months after the S2).
Arguments in favor of the Leica S2:
- More detail: Has more megapixels (37.5 vs 17.9MP), which boosts linear resolution by 45%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- More complete view: Has a viewfinder with a larger field of view (96% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.86x vs 0.54x).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- 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 heavily discounted: Has been on the market for longer (launched in September 2008).
If the count of relative strengths (bullet points above) is taken as a measure, the S2 is the clear winner of the contest (14 : 9 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.
How about other alternatives? Do the specifications of the Canon T2i and the Leica S2 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 T2i or the S2 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.

Care should be taken when interpreting the review scores above, 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.
