Leica M10 versus Leica SL

The Leica M10 (Typ 3656) and the Leica SL (Typ 601) are two enthusiast cameras that were announced, 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

The side-by-side display below illustrates the physical size and weight of the Leica M10 and the Leica SL. 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 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 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 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. 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 tend to be more expensive and 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.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. 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 variety 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 table below summarizes some of the other core capabilities of the Leica M10 and Leica SL in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

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 262, 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? The listing below highlights the relative strengths of the two models.


Reasons to prefer 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).

Advantages of 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 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 number of relative strengths (bullet points above) is taken as a guide, 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 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 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
