Sony A7R III versus Leica S2
The Sony Alpha A7R III and the Leica S2 are two digital cameras that were revealed to the public, respectively, in October 2017 and September 2008. The A7R III is a mirrorless interchangeable lens camera, while the S2 is a DSLR. The cameras are based on a full frame (A7R III) and a medium format sensor. The Sony has a resolution of 42.2 megapixel, whereas the Leica provides 37.5 MP.
The side-by-side display below illustrates the physical size and weight of the Sony A7R III and the Leica S2. Three successive views from the front, the top, and the rear are shown. All size 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 side – the A7R III – 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 S2 is considerably larger (57 percent) than the Sony A7R III. Moreover, the S2 is substantially heavier (117 percent) than the A7R III. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
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 A7R III was launched at a markedly lower price (by 86 percent) than the S2, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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. 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.
Of the two cameras under consideration, the Sony A7R III features a full frame sensor and the Leica S2 a medium format sensor. The sensor area in the S2 is 57 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 0.8. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Sony A7R III offers a higher resolution of 42.2 megapixel, compared with 37.5 MP of the Leica S2. 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 4.52μm versus 6.00μm for the S2). However, it should be noted that the A7R III is much more recent (by 9 years and 1 month) than the S2, 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.
Unlike the S2, the A7R III has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
For most cameras, data on sensor performance has been reported by DXO Mark. 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 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 A7R III indeed provides movie recording capabilities, while the S2 does not. The highest resolution format that the A7R III can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7R III has an electronic viewfinder (3686k dots), while the S2 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 following table reports on some other key feature differences and similarities of the Sony A7R III, the Leica S2, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

- Faster burst: Shoots at higher frequency (10 vs 1.5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (127x96mm vs 160x120mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 760g or 54 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More affordable: Was introduced into a lower priced category (86 percent cheaper at launch).
- More modern: Reflects 9 years and 1 month of technical progress since the S2 launch.
Advantages of the Leica S2:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Has a control panel on top to check shooting parameters.
- More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
- More heavily discounted: Has been around for much longer (launched in September 2008).
If the number of relative strengths (bullet points above) is taken as a guide, the A7R III is the clear winner of the match-up (15 : 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the A7R III or the S2. 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 full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
