Leica M9 versus Canon 5D Mark IV

The Leica M9 and the Canon EOS 5D Mark IV are two digital cameras that were officially introduced, respectively, in September 2009 and August 2016. The M9 is a rangefinder-style mirrorless camera, while the 5D Mark IV is a DSLR. Both cameras are equipped with a full frame sensor. The Leica has a resolution of 18.1 megapixel, whereas the Canon provides 30.1 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Leica M9 and the Canon 5D Mark IV. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display 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 M9 – 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 Canon 5D Mark IV is considerably larger (58 percent) than the Leica M9. Moreover, the 5D Mark IV is substantially heavier (52 percent) than the M9. It is noteworthy in this context that the 5D Mark IV 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can find an overview of optics for the two cameras in the Leica M Lens Catalog (M9) and the Canon EF Lens Catalog (5D Mark IV).

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

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 5D Mark IV was launched at a markedly lower price (by 56 percent) than the M9, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. 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 tent to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Leica M9 and Canon 5D Mark IV sensor measures
Sensor size

While the two cameras under review share the same sensor size, the 5D Mark IV offers a higher resolution of 30.1 megapixel, compared with 18.1 MP of the M9. This megapixel advantage translates into a 29 percent gain in linear resolution. On the other hand, these sensor specs imply that the 5D Mark IV has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.36μm versus 6.91μm for the M9). However, it should be noted that the 5D Mark IV is much more recent (by 6 years and 11 months) than the M9, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. 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.

Sensor resolution

For most 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 5D Mark IV offers substantially better image quality than the M9 (overall score 22 points higher). The advantage is based on 2.3 bits higher color depth, 1.9 EV in additional dynamic range, and 1.8 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 cannot only take still pictures, but also record videos. The 5D Mark IV indeed provides for movie recording, while the M9 does not. The highest resolution format that the 5D Mark IV can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The M9 and the 5D Mark IV 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 following table reports on some other key feature differences and similarities of the Leica M9, the Canon 5D Mark IV, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The 5D Mark IV is a current model that online retailers, such as amazon, will have in stock. In contrast, the M9 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the M9 was succeeded by the Leica M Typ 240.

Summary

So what conclusions can be drawn? Is there a clear favorite between the Leica M9 and the Leica M9? The listing below highlights the relative strengths of the two models.


logo checkmark

Arguments in favor of the Leica M9:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More compact: Is smaller (139x80mm vs 151x116mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 305g or 34 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).

logo checkmark

Reasons to prefer the Canon EOS 5D Mark IV:

  • More detail: Has more megapixels (30.1 vs 18.1MP), which boosts linear resolution by 29%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores substantially higher (22 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.9 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.8 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 230k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (7 vs 2 flaps/sec) to capture the decisive moment.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More affordable: Was introduced into a lower priced category (56 percent cheaper at launch).
  • More modern: Reflects 6 years and 11 months of technical progress since the M9 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 5D Mark IV is the clear winner of the contest (16 : 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.

M9 05:16 5D Mark IV

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 M9 and the 5D Mark IV in practical situations. 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. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
