Canon 100D vs Leica M8

The Canon EOS 100D (called Canon SL1 in some regions) and the Leica M8 are two digital cameras that were officially introduced, respectively, in March 2013 and September 2006. The 100D is a DSLR, while the M8 is a rangefinder-focusing mirrorless camera. The cameras are based on an APS-C (100D) and an APS-H (M8) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Leica provides 10.4 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 M8? 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

An illustration of the physical size and weight of the Canon 100D and the Leica M8 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 size dimensions are rounded to the nearest millimeter.

The 100D can be obtained in two different colors (black, white), while the M8 is also available in two color-versions, but different ones (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica M8 is somewhat larger (4 percent) than the Canon 100D. Moreover, the M8 is substantially heavier (45 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the M8 are weather-sealed.

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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (100D) and the Leica M Lens Catalog (M8).

Concerning battery life, the 100D gets 380 shots out of its Canon LP-E12 battery, while the M8 can take 550 images on a single charge of its Leica BLI-312 power pack.

The price is, of course, an important factor in any camera decision. 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 90 percent) than the M8, 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 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 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. 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 are more costly to manufacture and tend to 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 M8 an APS-H sensor. The sensor area in the M8 is 46 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.3. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the Canon 100D offers a higher resolution of 17.9 megapixels, compared with 10.4 MP of the Leica M8. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.31μm versus 6.84μm for the M8). However, it should be noted that the 100D is much more recent (by 6 years and 6 months) than the M8, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the M8 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon 100D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 100D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Leica M8 are 19.7 x 13.2 inches or 50 x 33.4 cm for good quality, 15.7 x 10.5 inches or 40 x 26.7 cm for very good quality, and 13.1 x 8.8 inches or 33.3 x 22.3 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 M8 are ISO 160 to ISO 2500 (no boost).

In terms of underlying technology, the 100D is build around a CMOS sensor, while the M8 uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under review, the 100D has a notably higher overall DXO score than the M8 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.7 bits higher color depth, and 0.3 stops in additional low light sensitivity. 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 also of capturing video footage. The 100D indeed provides movie recording capabilities, while the M8 does not. The highest resolution format that the 100D can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 100D and the M8 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 table below summarizes some of the other core capabilities of the Canon 100D and Leica M8 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 100D has one, while the M8 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.

Concerning the storage of imaging data, both the 100D and the M8 write their files to SDXC cards. The 100D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the M8 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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 M8 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 100D and the M8 have been discontinued, but can regularly be found used on ebay. The M8 was replaced by the Leica M9, while the 100D was followed by the Canon 200D. Further information on the features and operation of the 100D and M8 can be found, respectively, in the Canon 100D Manual (free pdf) or the online Leica M8 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon 100D or the Leica M8 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS 100D:

• More detail: Offers more megapixels (17.9 vs 10.4MP) with a 32% higher linear resolution.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (0.3 stops ISO advantage).
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k 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 2 flaps/sec) to capture the decisive moment.
• Less heavy: Is lighter (by 184g or 31 percent) and hence easier to carry around.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (90 percent cheaper at launch).
• More modern: Reflects 6 years and 6 months of technical progress since the M8 launch.

Arguments in favor of the Leica M8:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Longer lasting: Gets more shots (550 versus 380) out of a single battery charge.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More heavily discounted: Has been around for much longer (launched in September 2006).

If the count of relative strengths (bullet points above) is taken as a measure, the 100D is the clear winner of the match-up (15 : 5 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 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 100D or the M8. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. 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.

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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
