Leica SL vs T Typ 701
The Leica SL (Typ 601) and the Leica T (Typ 701) are two digital cameras that were announced, respectively, in October 2015 and April 2014. Both the SL and the T Typ 701 are mirrorless interchangeable lens cameras that are based on a full frame (SL) and an APS-C (T Typ 701) sensor. The SL has a resolution of 24 megapixels, whereas the T Typ 701 provides 16.2 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 SL (Typ 601) and the Leica T (Typ 701)? 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.
The physical size and weight of the Leica SL and the Leica T are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
The T Typ 701 can be obtained in two different colors (black, silver), while the SL 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 Leica T is considerably smaller (40 percent) than the Leica SL. Moreover, the T Typ 701 is substantially lighter (55 percent) than the SL. It is worth mentioning in this context that the SL is splash and dust resistant, 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 power pack in the T Typ 701 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.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The T Typ 701 was launched at a markedly lower price (by 75 percent) than the SL, 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.
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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Leica SL features a full frame sensor and the Leica T an APS-C sensor. The sensor area in the T Typ 701 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 24MP, the SL offers a higher resolution than the T Typ 701 (16.2MP), but the SL nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 4.79μm for the T Typ 701) due to its larger sensor. Moreover, the SL is a somewhat more recent model (by 1 year and 5 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 pixels. 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.
The resolution advantage of the Leica SL implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SL for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Leica T are 24.7 x 16.4 inches or 62.8 x 41.6 cm for good quality, 19.8 x 13.1 inches or 50.2 x 33.3 cm for very good quality, and 16.5 x 10.9 inches or 41.9 x 27.8 cm for excellent quality prints.
The Leica SL (Typ 601) has a native sensitivity range from ISO 50 to ISO 50000. The corresponding ISO settings for the Leica T (Typ 701) are ISO 100 to ISO 12500 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 review, the SL provides substantially higher image quality than the T Typ 701, with an overall score that is 13 points higher. This advantage is based on 2 bits higher color depth, 0.7 EV in additional dynamic range, and 0.8 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SL provides a higher video resolution than the T Typ 701. It can shoot video footage at 4K/30p, while the T Typ 701 is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the SL has an electronic viewfinder (4400k 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 SL and Leica T along with similar information for a selection of comparators.

One feature that is present on the SL, but is missing on the T Typ 701 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
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 SL 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 Leica SL has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the SL and the T Typ 701 write their files to SDXC cards. The SL features dual card slots, which can be very useful in case a memory card fails. In contrast, the T Typ 701 only has one slot. The SL supports UHS-II cards on its first slot and UHS-I on its second one, 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 SL (Typ 601) and Leica T (Typ 701) and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Leica M Typ 240||Y||stereo||mono||-||-||-||2.0||-||-||-|
It is notable that the SL has a microphone port, which is missing on the T Typ 701. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Leica SL (unlike the T Typ 701) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Travel and landscape photographers will find it useful that the SL has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the SL and the T Typ 701 have been discontinued, but can regularly be found used on eBay. The T Typ 701 was replaced by the Leica TL, while the SL was followed by the Leica SL2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica website.

If the count of relative strengths (bullet points above) is taken as a measure, the SL is the clear winner of the match-up (22 : 8 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. 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SL or the T Typ 701. 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 expert reviews 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.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
