Leica T vs Sony A7S II
The Leica T (Typ 701) and the Sony Alpha 7S II are two digital cameras that were announced, respectively, in April 2014 and September 2015. Both the T Typ 701 and the A7S II are mirrorless interchangeable lens cameras that are based on an APS-C (T Typ 701) and a full frame (A7S II) sensor. The Leica has a resolution of 16.2 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 T (Typ 701) 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.
An illustration of the physical size and weight of the Leica T and the Sony A7S II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The T Typ 701 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 (32 percent) than the Leica T. Moreover, the A7S II is substantially heavier (63 percent) than the T Typ 701. It is noteworthy in this context that the A7S II is splash and dust-proof, while the T Typ 701 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 and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T Typ 701 was launched at a markedly lower price (by 38 percent) than the A7S II, 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 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.
Of the two cameras under consideration, the Leica T features an APS-C sensor and the Sony A7S II a full frame sensor. The sensor area in the A7S II is 128 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Leica T offers a higher resolution of 16.2 megapixels, compared with 12 MP of the Sony A7S II. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.79μm versus 8.40μm for the A7S II). Moreover, it should be noted that the A7S II is a somewhat more recent model (by 1 year and 4 months) than the T Typ 701, 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 the T Typ 701 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Leica T implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T Typ 701 for good quality output (200 dots per inch) amounts to 24.7 x 16.4 inches or 62.8 x 41.6 cm, for very good quality (250 dpi) 19.8 x 13.1 inches or 50.2 x 33.3 cm, and for excellent quality (300 dpi) 16.5 x 10.9 inches or 41.9 x 27.8 cm. The corresponding values for the Sony A7S II are 21.2 x 14.2 inches or 53.8 x 36 cm for good quality, 17 x 11.3 inches or 43.1 x 28.8 cm for very good quality, and 14.1 x 9.4 inches or 35.9 x 24 cm for excellent quality prints.
The Leica T (Typ 701) has a native sensitivity range from ISO 100 to ISO 12500. 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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under consideration, the A7S II has a markedly higher DXO score than the T Typ 701 (overall score 10 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.6 EV in additional dynamic range, and 1.5 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7S II provides a better video resolution than the T Typ 701. It can shoot movie footage at 4K/30p, while the Leica is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7S II has an electronic viewfinder (2400k dots), which can be very helpful when shooting in bright sunlight. In contrast, the T Typ 701 relies on live view and the rear LCD for framing. That said, the T Typ 701 can be equipped with an optional viewfinder – the Visoflex (Typ 020). The adjacent table lists some of the other core features of the Leica T and Sony A7S II along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The T Typ 701 has one, while the A7S II does not. While the built-in flash of the T Typ 701 is not very powerful, it can at times be useful as a fill-in light.
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 T Typ 701 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 T Typ 701 cannot take advantage of Ultra High Speed SD cards.
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 T (Typ 701) 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 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The T Typ 701 lacks such a headphone port.
Both the T Typ 701 and the A7S II have been discontinued, but can regularly be found used on eBay. The T Typ 701 was replaced by the Leica TL, while the A7S II was followed by the Sony A7S III. 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.
So what conclusions can be drawn? Is there a clear favorite between the Leica T 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 individual advantages (bullet points above) is taken as a guide, the A7S II is the clear winner of the contest (16 : 10 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the T Typ 701 or the A7S II. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
