Leica M9 versus Leica M10

The Leica M9 and the Leica M10 (Typ 3656) are two enthusiast cameras that were revealed to the public, respectively, in September 2009 and January 2017. Both the M9 and the M10 Typ 3656 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 Typ 3656 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 successive views from the front, the top, and the rear are shown. 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 – the M9 – represents the basis or 100 percent 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 Typ 3656 is markedly heavier (13 percent) than the M9. In this context, it is worth noting that neither the M9 nor the M10 Typ 3656 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 Typ 3656 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 size of the imaging sensor is a crucial determinant 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. 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 Typ 3656 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.

Sensor size

Despite having a slightly smaller sensor, the M10 Typ 3656 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 Typ 3656 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

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

The M10 Typ 3656 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

Apart from body and sensor, cameras can and do differ across a range of features. The M9 and the M10 Typ 3656 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 table below summarizes some of the other core capabilities of the Leica M9 and Leica M10 in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The M10 Typ 3656 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? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer 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).

Advantages of the Leica M10 (Typ 3656):

  • More detail: Has more megapixels (23.8 vs 18.1MP), which boosts linear resolution by 14%.
  • 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 Typ 3656 is the clear winner of the contest (6 : 2 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the M9 and the M10 Typ 3656 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites.

The above review scores should be interpreted 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 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.
