Leica M10 vs Canon 1D Mark II

The Leica M10 (Typ 3656) and the Canon EOS-1D Mark II are two digital cameras that were announced, respectively, in January 2017 and January 2004. The M10 is a rangefinder-focusing mirrorless camera, while the 1D Mark II is a DSLR. The cameras are based on a full frame (M10) and an APS-H (1D Mark II) sensor. The Leica has a resolution of 23.8 megapixels, whereas the Canon provides 8.2 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 Leica M10 (Typ 3656) and the Canon EOS-1D Mark II? 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 Leica M10 and the Canon 1D Mark II 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 dimensions are rounded to the nearest millimeter.

The M10 can be obtained in two different colors (black, silver), while the 1D Mark II 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 Canon 1D Mark II is considerably larger (122 percent) than the Leica M10. Moreover, the 1D Mark II is substantially heavier (133 percent) than the M10. 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. 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 Leica M Lens Catalog (M10) and the Canon EF Lens Catalog (1D Mark II).

Concerning battery life, the M10 gets 210 shots out of its Leica BP-SCL5 battery, while the 1D Mark II can take 1200 images on a single charge of its Canon NP-E3 power pack. As can be seen in the images above, the 1D Mark II has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 1D Mark II 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

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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica M10 features a full frame sensor and the Canon 1D Mark II an APS-H sensor. The sensor area in the 1D Mark II is 36 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.3. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 23.8MP, the M10 offers a higher resolution than the 1D Mark II (8.2MP), but the M10 has smaller individual pixels (pixel pitch of 6.00μm versus 8.17μm for the 1D Mark II). However, the M10 is a much more recent model (by 12 years and 11 months) than the 1D Mark II, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. 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.

The resolution advantage of the Leica M10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10 for good quality output (200 dots per inch) amounts to 29.8 x 20 inches or 75.6 x 50.7 cm, for very good quality (250 dpi) 23.8 x 16 inches or 60.5 x 40.6 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inches or 50.4 x 33.8 cm. The corresponding values for the Canon 1D Mark II are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.

The Leica M10 (Typ 3656) has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Canon EOS-1D Mark II are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 50-3200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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. Of the two cameras under review, the M10 provides substantially higher image quality than the 1D Mark II, with an overall score that is 20 points higher. This advantage is based on 2.1 bits higher color depth, 2.1 EV in additional dynamic range, and 1.1 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

Apart from body and sensor, cameras can and do differ across a range of features. The M10 and the 1D Mark II 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 (100%), but the viewfinder of the M10 has a higher magnification than the one of the 1D Mark II (0.73x vs 0.55x), 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 Leica M10, the Canon 1D Mark II, and comparable cameras.

One feature that is present on the 1D Mark II, but is missing on the M10 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The Leica M10 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The M10 writes its imaging data to SDXC cards, while the 1D Mark II uses Compact Flash or SD cards. The 1D Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the M10 only has one slot. The M10 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1D Mark II 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 Leica M10 (Typ 3656) and Canon EOS-1D Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M10 offers wifi support, while the 1D Mark II does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Canon 1D Mark II (unlike the M10) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the M10 and the 1D Mark II have been discontinued, but can regularly be found used on ebay. The 1D Mark II was replaced by the Canon 1D Mark II N, while the M10 was followed by the Leica M11. Further information on the features and operation of the M10 and 1D Mark II can be found, respectively, in the Leica M10 Manual (free pdf) or the online Canon 1D Mark II Manual.

Review summary

So how do things add up? Is the Leica M10 better than the Canon 1D Mark II or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Leica M10 (Typ 3656):

• More detail: Offers more megapixels (23.8 vs 8.2MP) with a 70% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (20 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.1 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (2.1 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1.1 stops ISO advantage).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.55x).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 230k dots).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (139x80mm vs 156x158mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 875g or 57 percent) and hence easier to carry around.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More modern: Reflects 12 years and 11 months of technical progress since the 1D Mark II launch.

Arguments in favor of the Canon EOS-1D Mark II:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (8.3 vs 5 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (1200 versus 210) out of a single battery charge.
• 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.
• More affordable: Was introduced into a lower priced category (32 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in January 2004).

If the number of relative strengths (bullet points above) is taken as a guide, the M10 is the clear winner of the match-up (16 : 10 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the M10 or the 1D Mark II 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
