Canon 70D vs Leica S3

The Canon EOS 70D and the Leica S3 are two digital cameras that were announced, respectively, in July 2013 and September 2018. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (70D) and a medium format (S3) sensor. The Canon has a resolution of 20 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 70D 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 70D and the Leica S3. 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.

Size Canon 70D vs Leica S3
Compare 70D versus S3 top
Comparison 70D or S3 rear

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 (33 percent) than the Canon 70D. Moreover, the S3 is substantially heavier (67 percent) than the 70D. 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 70D was launched at a markedly lower price (by 94 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 70D features an APS-C sensor and the Leica S3 a medium format sensor. The sensor area in the S3 is 299 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.

Canon 70D and Leica S3 sensor measures

With 64MP, the S3 offers a higher resolution than the 70D (20MP), but the S3 nevertheless has larger individual pixels (pixel pitch of 4.59μm versus 4.11μm for the 70D) due to its larger sensor. Moreover, the S3 is a much more recent model (by 5 years and 2 months) than the 70D, 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 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 70D are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The 70D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 70D 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).

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the S3 provides a better video resolution than the 70D. It can shoot movie footage at 4K/24p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 70D 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 viewfinders of both cameras offer the same field of view (98%), but the viewfinder of the S3 has a higher magnification than the one of the 70D (0.87x vs 0.59x), 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 70D, the Leica S3, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The 70D has one, while the S3 does not. While the built-in flash of the 70D is not very powerful, it can at times be useful as a fill-in light.

The 70D 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 S3 does not have a selfie-screen.

The 70D 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 70D only has one slot. The S3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the 70D can use UHS-I cards (up to 104 MB/s).

It is notable that the S3 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The 70D lacks such a headphone port.

Studio photographers will appreciate that the Leica S3 (unlike the 70D) 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 70D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 70D was succeeded by the Canon 80D. 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.

Review summary

So what is the bottom line? Is the Canon 70D better than the Leica S3 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Canon EOS 70D:

  • 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).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (7 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (139x104mm vs 160x120mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 505g or 40 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 (94 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in July 2013).

ilogo

Reasons to prefer the Leica S3:

  • More detail: Has more megapixels (64 vs 20MP), which boosts linear resolution by 79%.
  • 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.
  • Better video: Provides higher definition movie capture (4K/24p vs 1080/30p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.87x vs 0.59x).
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • 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.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
  • More modern: Reflects 5 years and 2 months of technical progress since the 70D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the S3 emerges as the winner of the match-up (16 : 13 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 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.

70D 13:16 S3

How about other alternatives? Do the specifications of the Canon 70D 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 70D or the S3 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.

Expert reviews

This is why expert reviews 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
