Canon 100D vs Leica S3
The Canon EOS 100D (called Canon SL1 in some regions) and the Leica S3 are two digital cameras that were revealed to the public, respectively, in March 2013 and September 2018. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (100D) and a medium format (S3) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Leica provides 64 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 100D and the Leica S3? 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 100D and the Leica S3 is provided 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.
The 100D can be obtained in two different colors (black, white), while the S3 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 S3 is considerably larger (80 percent) than the Canon 100D. Moreover, the S3 is substantially heavier (210 percent) than the 100D. It is noteworthy in this context that the S3 is splash and dust-proof, while the 100D 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.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 100D was launched at a markedly lower price (by 98 percent) than the S3, 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. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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.
Of the two cameras under consideration, the Canon 100D features an APS-C sensor and the Leica S3 a medium format sensor. The sensor area in the S3 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.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 64MP, the S3 offers a higher resolution than the 100D (17.9MP), but the S3 nevertheless has larger individual pixels (pixel pitch of 4.59μm versus 4.31μm for the 100D) due to its larger sensor. Moreover, the S3 is a much more recent model (by 5 years and 6 months) than the 100D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the S3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Leica S3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S3 for good quality output (200 dots per inch) amounts to 49 x 32.7 inch or 124.5 x 83 cm, for very good quality (250 dpi) 39.2 x 26.1 inch or 99.6 x 66.4 cm, and for excellent quality (300 dpi) 32.7 x 21.8 inch or 83 x 55.3 cm. The corresponding values for the Canon 100D are 25.9 x 17.3 inch or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inch or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inch or 43.9 x 29.3 cm for excellent quality prints.
The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 100D 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 S3 are ISO 100 to ISO 50000 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the S3 provides a better video resolution than the 100D. It can shoot movie footage at 4K/24p, while the Canon is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The 100D and the S3 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 S3 offers a wider field of view (98%) than the one in the 100D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the S3 has a higher magnification (0.87x 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 100D, the Leica S3, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The 100D has one, while the S3 does not. While the built-in flash of the 100D is not very powerful, it can at times be useful as a fill-in light.
The 100D writes its imaging data to SDXC cards, while the S3 uses Compact Flash or SDXC cards. The S3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 100D only has one slot. The S3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the 100D can use UHS-I cards (up to 104 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 100D and Leica S3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 100D does not offer wifi capability.
Studio photographers will appreciate that the Leica S3 (unlike the 100D) 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 S3 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The S3 is a recent model that features in the current product line-up of Leica. In contrast, the 100D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 100D was succeeded by the Canon 200D. 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 100D better than the Leica S3 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS 100D:
- 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 detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster burst: Shoots at higher frequency (4.9 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (117x91mm vs 160x120mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 853g or 68 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 (98 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in March 2013).
Reasons to prefer the Leica S3:
- More detail: Has more megapixels (64 vs 17.9MP), which boosts linear resolution by 89%.

- More modern: Reflects 5 years and 6 months of technical progress since the 100D launch.
If the number of relative strengths (bullet points above) is taken as a guide, the S3 is the clear winner of the contest (20 : 10 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.
How about other alternatives? Do the specifications of the Canon 100D and the Leica S3 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the 100D and the S3 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
