Canon 1D Mark III versus Leica M10

The Canon EOS-1D Mark III and the Leica M10 (Typ 3656) are two digital cameras that were announced, respectively, in February 2007 and January 2017. The 1D Mark III is a DSLR, while the M10 is a rangefinder-style mirrorless camera. The cameras are based on an APS-H (1D Mark III) and a full frame (M10) sensor. The Canon has a resolution of 10.1 megapixel, whereas the Leica provides 23.8 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 1D Mark III vs Leica M10

An illustration of the physical size and weight of the Canon 1D Mark III and the Leica M10 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. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the 1D Mark III – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica M10 is considerably smaller (54 percent) than the Canon 1D Mark III. Moreover, the M10 is substantially lighter (43 percent) than the 1D Mark III. It is worth mentioning in this context that the 1D Mark III is splash and dust resistant, while the M10 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (1D Mark III) and the Leica M Lens Catalog (M10).

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 1D Mark III was launched at a markedly lower price (by 32 percent) than the M10, 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: Canon 1D Mark III vs Leica M10

The size of the imaging sensor is a crucial determinant 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D Mark III features an APS-H sensor and the Leica M10 a full frame sensor. The sensor area in the M10 is 63 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.0. 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 23.8MP, the M10 offers a higher resolution than the 1D Mark III (10.1MP), but the M10 has smaller individual pixels (pixel pitch of 6.00μm versus 7.21μm for the 1D Mark III). Yet, the M10 is a much more recent model (by 9 years and 10 months) than the 1D Mark III, 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 M10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the M10 offers substantially better image quality than the 1D Mark III (overall score 15 points higher). The advantage is based on 1.7 bits higher color depth, 1.5 EV in additional dynamic range, and 1 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison: Canon 1D Mark III vs Leica M10

Beyond body and sensor, cameras can and do differ across a range of features. The 1D Mark III and the M10 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 adjacent table lists some of the other core features of the Canon 1D Mark III and Leica M10 along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The M10 is a current model that online retailers, such as amazon, will have in stock. In contrast, the 1D Mark III has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1D Mark III was succeeded by the Canon 1D Mark IV.

Review summary: Canon 1D Mark III vs Leica M10

So how do things add up? Is there a clear favorite between the Canon 1D Mark III and the Leica M10? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon EOS-1D Mark III:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Easier setting verification: Has an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
• Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (2200 versus 210) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• More affordable: Was introduced into a lower priced category (32 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in February 2007).

Arguments in favor of the Leica M10 (Typ 3656):

• More detail: Has more megapixels (23.8 vs 10.1MP), which boosts linear resolution by 53%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (15 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.7 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
• More detailed LCD: Has a higher resolution rear screen (1037k vs 230k dots).
• More compact: Is smaller (139x80mm vs 156x156.6mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 495g or 43 percent) and is thus easier to take along.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More modern: Reflects 9 years and 10 months of technical progress since the 1D Mark III launch.

If the number of relative strengths (bullet points above) is taken as a guide, the M10 emerges as the winner of the match-up (11 : 8 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.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 1D Mark III and the M10 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
