Leica M9 vs Sony A7S II
The Leica M9 and the Sony Alpha 7S II are two digital cameras that were revealed to the public, respectively, in September 2009 and September 2015. The M9 is a fixed lens compact, while the A7S II is a rangefinder-style mirrorless. Both cameras are equipped with a full frame sensor. The Leica has a resolution of 18.1 megapixels, whereas the Sony provides 12 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M9 and the Sony Alpha 7S II? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
Body comparison: Leica M9 vs Sony A7S II
The physical size and weight of the Leica M9 and the Sony A7S II are illustrated 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 measures are rounded to the nearest millimeter.
The M9 can be obtained in two different colors (black, silver), while the A7S II is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7S II is notably larger (10 percent) than the Leica M9. Moreover, the A7S II is markedly heavier (7 percent) than the M9. It is noteworthy in this context that the A7S II is splash and dust-proof, while the M9 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 compare the optics available for the two cameras in the Leica M Lens Catalog (M9) and the Sony FE Lens Catalog (A7S II).
The power pack in the A7S II can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 camera comparisons there.

Any camera decision will naturally be influenced heavily by the price. 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 A7S II was launched at a markedly lower price (by 63 percent) than the M9, which puts it into a different market segment. 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.
Sensor comparison: Leica M9 vs Sony A7S II
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 tend 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 A7S II is 2 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.
With 18.1MP, the M9 offers a higher resolution than the A7S II (12MP), but the M9 has smaller individual pixels (pixel pitch of 6.91μm versus 8.40μm for the A7S II). Moreover, the A7S II is a much more recent model (by 6 years) than the M9, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the M9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Leica M9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M9 for good quality output (200 dots per inch) amounts to 26.1 x 17.4 inch or 66.2 x 44.1 cm, for very good quality (250 dpi) 20.8 x 13.9 inch or 53 x 35.3 cm, and for excellent quality (300 dpi) 17.4 x 11.6 inch or 44.1 x 29.4 cm. The corresponding values for the Sony A7S II are 21.2 x 14.2 inch or 53.8 x 36 cm for good quality, 17 x 11.3 inch or 43.1 x 28.8 cm for very good quality, and 14.1 x 9.4 inch or 35.9 x 24 cm for excellent quality prints.
The Leica M9 has a native sensitivity range from ISO 80 to ISO 2500. The corresponding ISO settings for the Sony Alpha 7S II are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-409600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 A7S II offers substantially better image quality than the M9 (overall score 16 points higher). The advantage is based on 1.1 bits higher color depth, 1.6 EV in additional dynamic range, and 1.8 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The A7S II indeed provides for movie recording, while the M9 does not. The highest resolution format that the A7S II can use is 4K/30p.
Feature comparison: Leica M9 vs Sony A7S II
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7S II has an electronic viewfinder (2400k dots), while the M9 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the A7S II has a higher magnification than the one of the M9 (0.78x vs 0.68x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Leica M9 and Sony A7S II in connection with corresponding information for a sample of similar cameras.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7S II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The M9 writes its imaging data to SDXC cards, while the A7S II uses SDXC or Memory Stick PRO Duo cards. The A7S II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the M9 cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison: Leica M9 vs Sony A7S II
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Leica M9 and Sony Alpha 7S II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7S II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the M9 does not offer wifi capability.
The A7S II is a recent model that features in the current product line-up of Sony. 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. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Sony websites.
Review summary: Leica M9 vs Sony A7S II
So how do things add up? Is there a clear favorite between the Leica M9 and the Sony A7S II? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

If the count of relative strengths (bullet points above) is taken as a measure, the A7S II is the clear winner of the contest (21 : 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 when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the M9 and the A7S II 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.
Expert reviews: Leica M9 vs Sony A7S II
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
