Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X100T and the Leica S2? 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

The side-by-side display below illustrates the physical size and weight of the Fujifilm X100T and the Leica S2. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

The X100T can be obtained in two different colors (black, silver), while the S2 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 S2 is considerably larger (104 percent) than the Fujifilm X100T. It is noteworthy in this context that the S2 is splash and dust-proof, while the X100T does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100T has a lens built in, whereas the S2 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the X100T gets 330 shots out of its Fujifilm NP-95 battery, while the S2 can take .. images on a single charge of its Leica BP-PRO1 power pack. The power pack in the X100T can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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 X100T was launched at a lower price than the S2, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 Fujifilm X100T features an APS-C sensor and the Leica S2 a medium format sensor. The sensor area in the S2 is 267 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 0.8. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 37.5MP, the S2 offers a higher resolution than the X100T (16MP), but the S2 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 4.80μm for the X100T) due to its larger sensor. However, the X100T is a much more recent model (by 5 years and 11 months) than the S2, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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 S2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S2 for good quality output (200 dots per inch) amounts to 37.5 x 25 inches or 95.3 x 63.5 cm, for very good quality (250 dpi) 30 x 20 inches or 76.2 x 50.8 cm, and for excellent quality (300 dpi) 25 x 16.7 inches or 63.5 x 42.3 cm. The corresponding values for the Fujifilm X100T are 24.5 x 16.3 inches or 62.2 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.7 x 33.2 cm for very good quality, and 16.3 x 10.9 inches or 41.5 x 27.6 cm for excellent quality prints.

The X100T has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Fujifilm X100T has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-51200. The corresponding ISO settings for the Leica S2 are ISO 80 to ISO 1250 (no boost).

In terms of underlying technology, the X100T is build around a CMOS sensor, while the S2 uses a CCD imager. The X100T uses Fujifilm's X-Trans layout of photosites, while the S2 employs the more common Bayer array.

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. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The X100T indeed provides movie recording capabilities, while the S2 does not. The highest resolution format that the X100T can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the X100T has an electronic viewfinder (2360k 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 viewfinder in the X100T offers a wider field of view (100%) than the one in the S2 (96%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the S2 has a higher magnification (0.86x vs 0.43x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Fujifilm X100T, the Leica S2, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The X100T has one, while the S2 does not. While the built-in flash of the X100T is not very powerful, it can at times be useful as a fill-in light.

The Fujifilm X100T 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.

The X100T writes its imaging data to SDXC cards, while the S2 uses Compact Flash or SDHC cards. The S2 features dual card slots, which can be very useful in case a memory card fails. In contrast, the X100T only has one slot. The X100T supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the S2 cannot take advantage of Ultra High Speed SD cards.

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 Fujifilm X100T and Leica S2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X100T offers wifi support, while the S2 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Leica S2 (unlike the X100T) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the X100T and the S2 have been discontinued, but can regularly be found used on ebay. The S2 was replaced by the Leica S Typ 006, while the X100T was followed by the Fujifilm X100F. Further information on the features and operation of the X100T and S2 can be found, respectively, in the Fujifilm X100T Manual (free pdf) or the online Leica S2 Manual.

Review summary

So how do things add up? Which of the two cameras – the Fujifilm X100T or the Leica S2 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Fujifilm X100T:

• Broader imaging potential: Can record not only still images but also 1080/60p movies.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More complete view: Has a viewfinder with a larger field of view (100% vs 96%).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
• Faster burst: Shoots at higher frequency (6 vs 1.5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with a built-in lens, while the S2 requires a separate lens.
• More compact: Is smaller (127x74mm vs 160x120mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the S2).
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 5 years and 11 months of technical progress since the S2 launch.

Advantages of the Leica S2:

• More detail: Has more megapixels (37.5 vs 16MP), which boosts linear resolution by 53%.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.86x vs 0.43x).
• Easier setting verification: Features a control panel on top to check shooting parameters.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• 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 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 count of relative strengths (bullet points above) is taken as a measure, the X100T is the clear winner of the match-up (16 : 10 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 Fujifilm X100T and the Leica S2 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the X100T or the S2 perform in practice. 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

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.

Care should be taken when interpreting the review scores above, 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
