Leica M10 versus Leica SL

The Leica M10 (Typ 3656) and the Leica SL (Typ 601) are two enthusiast cameras that were officially introduced, respectively, in January 2017 and October 2015. The M10 is a fixed lens compact, while the SL is a rangefinder-style mirrorless. Both cameras are equipped with a full frame sensor. The M10 has a resolution of 23.8 megapixel, whereas the SL provides 24 MP.

Body comparison

An illustration of the physical size and weight of the Leica M10 and the Leica SL 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 dimensions 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 M10 – 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 Leica SL is considerably larger (37 percent) than the Leica M10. Moreover, the SL is markedly heavier (28 percent) than the M10. It is noteworthy in this context that the SL is splash and dust-proof, while the M10 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. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

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 11 percent) than the SL, 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 sensor inside a digital camera is one of the key determinants 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. 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 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 SL is 1 percent bigger. 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

With 24MP, the SL offers a higher resolution than the M10 (23.8MP), but the SL nevertheless has the same individual pixel size (pixel pitch of 6.00μm) as the M10 due to its larger sensor. Moreover, the M10 is a somewhat more recent model (by 1 year and 2 months) than the SL, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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.

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.

Many modern cameras cannot only take still pictures, but also record videos. The SL indeed provides for movie recording, while the M10 does not. The highest resolution format that the SL can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the SL has an electronic viewfinder (4400k dots), while the M10 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Leica M10 and Leica SL along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the M10 and the SL are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The M10 replaced the earlier Leica M (Typ 240), while the SL does not have a direct predecessor.

Summary

So how do things add up? Is there a clear favorite between the Leica M10 and the Leica M10? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Leica M10 (Typ 3656):

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • More compact: Is smaller (139x80mm vs 147x104mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 187g or 22 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (11 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 2 months after the SL).

Reasons to prefer the Leica SL (Typ 601):

  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (11 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (400 versus 210) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More heavily discounted: Has been on the market for longer (launched in October 2015).

If the count of relative strengths (bullet points above) is taken as a measure, the SL is the clear winner of the contest (9 : 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.

M10 05:09 SL

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 M10 or the SL handle or 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. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites.

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
