Leica M9 vs Canon 80D

The Leica M9 and the Canon EOS 80D are two enthusiast cameras that were revealed to the public, respectively, in September 2009 and February 2016. The M9 is a rangefinder-focusing mirrorless camera, while the 80D is a DSLR. The cameras are based on a full frame (M9) and an APS-C (80D) sensor. The Leica has a resolution of 18.1 megapixels, whereas the Canon provides 24 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 M9 and the Canon EOS 80D? 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 M9 and the Canon 80D 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 M9 can be obtained in two different colors (black, silver), while the 80D 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 80D is notably larger (31 percent) than the Leica M9. Moreover, the 80D is markedly heavier (25 percent) than the M9. It is noteworthy in this context that the 80D is splash and dust-proof, while the M9 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 compare the optics available for the two cameras in the Leica M Lens Catalog (M9) and the Canon EF Lens Catalog (80D).

Concerning battery life, the M9 gets 550 shots out of its Leica BLI-312 battery, while the 80D can take 960 images on a single charge of its Canon LP-E6N power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 80D was launched at a markedly lower price (by 85 percent) than the M9, 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. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Leica M9 features a full frame sensor and the Canon 80D an APS-C sensor. The sensor area in the 80D is 61 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the 80D offers a higher resolution of 24 megapixels, compared with 18.1 MP of the M9. 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 3.75μm versus 6.91μm for the M9). However, it should be noted that the 80D is much more recent (by 6 years and 5 months) than the M9, 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 M9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon 80D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 80D for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Leica M9 are 26.1 x 17.4 inches or 66.2 x 44.1 cm for good quality, 20.8 x 13.9 inches or 53 x 35.3 cm for very good quality, and 17.4 x 11.6 inches or 44.1 x 29.4 cm for excellent quality prints.

The 80D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Leica M9 has a native sensitivity range from ISO 80 to ISO 2500. The corresponding ISO settings for the Canon EOS 80D are ISO 100 to ISO 16000, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the M9 is build around a CCD sensor, while the 80D uses a CMOS 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 consideration, the 80D has a markedly higher DXO score than the M9 (overall score 10 points higher), which will translate into better image quality. The advantage is based on 1.1 bits higher color depth, 1.5 EV in additional dynamic range, and 0.4 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The 80D indeed provides for movie recording, while the M9 does not. The highest resolution format that the 80D can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The M9 and the 80D 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 M9 has a higher magnification than the one of the 80D (0.68x vs 0.59x), 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 Leica M9 and Canon 80D along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 80D has a touchscreen, while the M9 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon 80D 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.

Concerning the storage of imaging data, both the M9 and the 80D write their files to SDXC cards. The 80D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the M9 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 M9 and Canon EOS 80D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 80D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the M9 does not provide wifi capability.

Both the M9 and the 80D have been discontinued, but can regularly be found used on ebay. The M9 was replaced by the Leica M Typ 240, while the 80D was followed by the Canon 90D. Further information on the features and operation of the M9 and 80D can be found, respectively, in the Leica M9 Manual (free pdf) or the online Canon 80D Manual.

Review summary

So what is the bottom line? Is the Leica M9 better than the Canon 80D or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Leica M9:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.68x vs 0.59x).
• More compact: Is smaller (139x80mm vs 139x105mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 145g or 20 percent) and hence easier to carry around.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More heavily discounted: Has been available for much longer (launched in September 2009).

Advantages of the Canon EOS 80D:

• More detail: Has more megapixels (24 vs 18.1MP), which boosts linear resolution by 15%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.1 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 (0.4 stops ISO advantage).
• Broader imaging potential: Can capture not only stills but also 1080/60p video.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• 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).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• 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 2 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Longer lasting: Gets more shots (960 versus 550) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (85 percent cheaper at launch).
• More modern: Reflects 6 years and 5 months of technical progress since the M9 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 80D is the clear winner of the contest (25 : 6 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 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 M9 or the 80D 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 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
