Canon 10D vs Leica S3
The Canon EOS 10D and the Leica S3 are two digital cameras that were revealed to the public, respectively, in February 2003 and September 2018. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (10D) and a medium format (S3) sensor. The Canon has a resolution of 6.3 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 10D 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.
The physical size and weight of the Canon 10D and the Leica S3 are illustrated 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 S3 is notably larger (20 percent) than the Canon 10D. Moreover, the S3 is substantially heavier (48 percent) than the 10D. It is noteworthy in this context that the S3 is splash and dust-proof, while the 10D 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 naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 10D was launched at a markedly lower price (by 89 percent) than the S3, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 10D features an APS-C sensor and the Leica S3 a medium format sensor. The sensor area in the S3 is 294 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 64MP, the S3 offers a higher resolution than the 10D (6.3MP), but the S3 has smaller individual pixels (pixel pitch of 4.59μm versus 7.38μm for the 10D). Yet, the S3 is a much more recent model (by 15 years and 7 months) than the 10D, and its sensor will 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 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 inches or 124.5 x 83 cm, for very good quality (250 dpi) 39.2 x 26.1 inches or 99.6 x 66.4 cm, and for excellent quality (300 dpi) 32.7 x 21.8 inches or 83 x 55.3 cm. The corresponding values for the Canon 10D are 15.4 x 10.2 inches or 39 x 26 cm for good quality, 12.3 x 8.2 inches or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inches or 26 x 17.3 cm for excellent quality prints.
The Canon EOS 10D has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Leica S3 are ISO 100 to ISO 50000 (no boost).
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 can also record movies. The S3 indeed provides for movie recording, while the 10D does not. The highest resolution format that the S3 can use is 4K/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 10D 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 10D (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 0.55x), 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 10D and Leica S3 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 10D has one, while the S3 does not. While the built-in flash of the 10D is not very powerful, it can at times be useful as a fill-in light.
The 10D writes its imaging data to Compact Flash 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 10D 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 10D 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 10D does not provide wifi capability.
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
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 10D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 10D was succeeded by the Canon 20D. 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 10D and the Leica S3? 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 10D:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More compact: Is smaller (150x107mm vs 160x120mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 410g or 33 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 (89 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in February 2003).
Advantages of the Leica S3:
- More detail: Has more megapixels (64 vs 6.3MP), which boosts linear resolution by 219%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Is equipped with a larger and more technologically advanced sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- Broader imaging potential: Can capture not only stills but also 4K/24p video.
- More complete view: Has a viewfinder with a larger field of view (98% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.87x vs 0.55x).
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (922k vs 118k dots).
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Easier geotagging: Features an internal GPS sensor to log localization data.
- Faster data transfer: Supports a more advanced USB protocol (3.0 vs 1.1).
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- 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 15 years and 7 months of technical progress since the 10D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the S3 is the clear winner of the contest (18 : 6 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 10D 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 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 10D or the S3 perform in practice. 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 why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
