Leica M9 versus Leica M10

The Leica M9 and the Leica M10 (Typ 3656) are two enthusiast cameras that were officially introduced, respectively, in September 2009 and January 2017. Both the M9 and the M10 are rangefinder-style mirrorless cameras that are equipped with a full frame sensor. The M9 has a resolution of 18.1 megapixel, whereas the M10 provides 23.8 MP.

Body comparison

An illustration of the physical size and weight of the Leica M9 and the Leica M10 is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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 M9 – represents the basis for the calculations across all the size and weight measures).

In this particular case, the Leica M9 and the Leica M10 have exactly the same width and height, and, thus, have identically-sized bodies. However, the M10 is markedly heavier (13 percent) than the M9. In this context, it is worth noting that neither the M9 nor the M10 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Leica M Lens Catalog.

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 M10 was launched at a somewhat lower price (by 18 percent) than the M9, which makes it more attractive for photographers on a tight budget. 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 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 tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 tent to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the M10 is 1 percent smaller. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Leica M9 and Leica M10 sensor measures
Sensor size

Despite having a slightly smaller sensor, the M10 offers a higher resolution of 23.8 megapixel, compared with 18.1 MP of the M9. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 6.00μm versus 6.91μm for the M9). However, it should be noted that the M10 is much more recent (by 7 years and 4 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

Sensor resolution

For most 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 M10 offers substantially better image quality than the M9 (overall score 17 points higher). The advantage is based on 1.9 bits higher color depth, 1.5 EV in additional dynamic range, and 1.3 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.

The M10 offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The M9 lacks this capability. Both cameras are still-image focused and cannot record videos.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The M9 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 following table reports on some other key feature differences and similarities of the Leica M9, the Leica M10, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The M10 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? Which of the two cameras – the Leica M9 or the Leica M10 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Leica M9:

  • Less heavy: Is lighter (by 75g or 11 percent) and hence easier to carry around.
  • More heavily discounted: Has been available for much longer (launched in September 2009).

Reasons to prefer the Leica M10 (Typ 3656):

  • More detail: Has more megapixels (23.8 vs 18.1MP), which boosts linear resolution by 14%.
  • Better image quality: Scores substantially higher (17 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.9 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 (1.3 stops ISO advantage).
  • 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 (1037k vs 230k dots).
  • Faster burst: Shoots at higher frequency (5 vs 2 flaps/sec) to capture the decisive moment.
  • More affordable: Was released into a lower priced segment (18 percent cheaper at launch).
  • More modern: Reflects 7 years and 4 months of technical progress since the M9 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the M10 is the clear winner of the contest (10 : 2 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.

M9 02:10 M10

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the M9 or the M10 handle or perform in practice. 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 expert reviews are important. The table below summarizes the assessments of some of the best known 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.

The review scores listed above should be treated with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
