Going beyond this snapshot of core features and characteristics, what are the differences between the Leica S3 and the Leica TL2? 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

An illustration of the physical size and weight of the Leica S3 and the Leica TL2 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.

The TL2 can be obtained in two different colors (black, silver), while the S3 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 TL2 is considerably smaller (52 percent) than the Leica S3. Moreover, the TL2 is substantially lighter (68 percent) than the S3. It is worth mentioning in this context that the S3 is splash and dust resistant, while the TL2 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.

Concerning battery life, the S3 gets .. shots out of its Leica BP-PRO1 battery, while the TL2 can take 250 images on a single charge of its Leica BP-DC13 power pack. The power pack in the TL2 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 would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. 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 TL2 was launched at a markedly lower price (by 90 percent) than the S3, 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

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.

Of the two cameras under consideration, the Leica S3 features a medium format sensor and the Leica TL2 an APS-C sensor. The sensor area in the TL2 is 73 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.8 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 64MP, the S3 offers a higher resolution than the TL2 (24.1MP), but the S3 nevertheless has larger individual pixels (pixel pitch of 4.59μm versus 3.92μm for the TL2) due to its larger sensor. Moreover, the S3 is a somewhat more recent model (by 1 year and 2 months) than the TL2, 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 S3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S3 for good quality output (200 dots per inch) amounts to 49 x 32.7 inches or 124.5 x 83 cm, for very good quality (250 dpi) 39.2 x 26.1 inches or 99.6 x 66.4 cm, and for excellent quality (300 dpi) 32.7 x 21.8 inches or 83 x 55.3 cm. The corresponding values for the Leica TL2 are 30.1 x 20.1 inches or 76.4 x 51 cm for good quality, 24.1 x 16.1 inches or 61.1 x 40.8 cm for very good quality, and 20 x 13.4 inches or 50.9 x 34 cm for excellent quality prints.

The Leica S3 has a native sensitivity range from ISO 100 to ISO 50000. The Leica TL2 offers exactly the same ISO settings.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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"). 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the TL2 provides a faster frame rate than the S3. It can shoot movie footage at 4K/30p, while the S3 is limited to 4K/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the S3 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the TL2 relies on live view and the rear LCD for framing. That said, the TL2 can be equipped with an optional viewfinder – the Visoflex (Typ 020). The adjacent table lists some of the other core features of the Leica S3 and Leica TL2 along with similar information for a selection of comparators.

One feature that is present on the S3, but is missing on the TL2 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 S3 writes its imaging data to Compact Flash or SDXC cards, while the TL2 uses SDXC cards. The S3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the TL2 only has one slot. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.

Connectivity comparison

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 S3 and Leica TL2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S3 has a microphone port, which is missing on the TL2. 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 S3 (unlike the TL2) 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 S3 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the S3 and the TL2 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Leica. Further information on the features and operation of the S3 and TL2 can be found, respectively, in the Leica S3 Manual (free pdf) or the online Leica TL2 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Leica S3 or the Leica TL2 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Leica S3:

• More detail: Offers more megapixels (64 vs 24.1MP) with a 63% higher linear resolution.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More modern: Is somewhat more recent (announced 1 year and 2 months after the TL2).

Arguments in favor of the Leica TL2:

• Better video: Provides higher movie framerates (4K/30p versus 4K/24p).
• Larger screen: Has a bigger rear LCD (3.7" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1230k vs 922k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (7 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (134x69mm vs 160x120mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 861g or 68 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• More affordable: Was introduced into a lower priced category (90 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in July 2017).

If the count of individual advantages (bullet points above) is taken as a guide, the S3 emerges as the winner of the contest (14 : 11 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Leica S3 and the Leica TL2 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

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 S3 or the TL2. 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.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The ratings are only valid when referring 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.
