Leica M10 versus Sony A7 II

The Leica M10 (Typ 3656) and the Sony Alpha A7 II are two enthusiast cameras that were revealed to the public, respectively, in January 2017 and November 2014. The M10 is a fixed lens compact, while the A7 II is a rangefinder-style mirrorless. Both cameras are equipped with a full frame sensor. The Leica has a resolution of 23.8 megapixel, whereas the Sony provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Leica M10 vs Sony A7 II

An illustration of the physical size and weight of the Leica M10 and the Sony A7 II is provided in the side-by-side display below. The two cameras are presented according to their relative size. 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the M10 – represents the basis or 100 percent 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 Sony A7 II is notably larger (10 percent) than the Leica M10. However, the A7 II is markedly lighter (9 percent) than the M10. It is noteworthy in this context that the A7 II 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. 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 (M10) and the Sony FE Lens Catalog (A7 II).

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

The camera’s price is obviously a critical decision-making factor. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The A7 II was launched at a markedly lower price (by 70 percent) than the M10, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

 

Sensor comparison: Leica M10 vs Sony A7 II

The size of the imaging sensor is a crucial determinant 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. 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 tend to be associated with larger, more expensive camera bodies 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 M10 and Sony A7 II sensor measures

While the two cameras under review share the same sensor size, the A7 II offers a slightly higher resolution of 24 megapixel, compared with 23.8 MP of the M10. This megapixel advantage translates into a 0.8 percent gain in linear resolution. On the other hand, these sensor specs imply that the A7 II has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.97μm versus 6.00μm for the M10). Moreover, it should be noted, that the M10 is much more recent (by 2 years and 1 month) than the A7 II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. Coming back to sensor resolution, it should be mentioned that the M10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

M10 versus A7 II MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the A7 II has a markedly higher DXO score than the M10 (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.5 bits higher color depth, 0.4 EV in additional dynamic range, and 0.2 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.

Many modern cameras cannot only take still pictures, but also record videos. The A7 II indeed provides for movie recording, while the M10 does not. The highest resolution format that the A7 II can use is 1080/60p.

 

Feature comparison: Leica M10 vs Sony A7 II

Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7 II has an electronic viewfinder (2400k 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 Sony A7 II along with similar information for a selection of comparators.

The M10 is a current model that online retailers, such as amazon, will have in stock. In contrast, the A7 II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A7 II was succeeded by the Sony A7 III.

Review summary: Leica M10 vs Sony A7 II

So what is the bottom line? Which of the two cameras – the Leica M10 or the Sony A7 II – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Leica M10 (Typ 3656):

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
  • More modern: Reflects 2 years and 1 month of technical progress since the A7 II launch.

ilogo

Arguments in favor of the Sony Alpha A7 II:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 1037k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Longer lasting: Gets more shots (350 versus 210) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in November 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the A7 II is the clear winner of the contest (12 : 4 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 before making a camera decision.

M10 04:12 A7 II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the M10 or the A7 II. 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 expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, 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.
