Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm FinePix X100 and the Leica X1? 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 Fujifilm X100 and the Leica X1 is provided 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 X1 can be obtained in two different colors (black, silver), while the X100 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 X1 is notably smaller (21 percent) than the Fujifilm X100. Moreover, the X1 is markedly lighter (31 percent) than the X100. In this context, it is worth noting that neither the X100 nor the X1 are weather-sealed.

Concerning battery life, the X100 gets 300 shots out of its Fujifilm NP-95 battery, while the X1 can take 260 images on a single charge of its Leica BP-DC8 power pack.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X100 was launched at a markedly lower price (by 40 percent) than the X1, 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 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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the X1 is 1 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Even though the X100 has a slightly larger sensor, both cameras offer the same resolution of 12.2 megapixels. This implies that the X100 has a lower pixel density and larger individual pixels (with a pixel pitch of 5.53μm versus 5.51μm for the X1), which gives it a potential advantage in terms of light gathering capacity. In addition, the X100 is a somewhat more recent model (by 1 year) than the X1, and its sensor might have benefitted from technological advances during this time.

The Fujifilm FinePix X100 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Leica X1 are ISO 100 to ISO 3200 (no boost).

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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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 also of capturing video footage. The X100 indeed provides movie recording capabilities, while the X1 does not. The highest resolution format that the X100 can use is 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the X100 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Fujifilm X100 and Leica X1 along with similar information for a selection of comparators.

Both the X100 and the X1 have built-in prime lenses. The X100 has a 35mm f/2.0 optic and the X1 offers a 36mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Fujifilm provides a wider angle of view than the Leica. The X100 offers the faster maximum aperture.

The X100 writes its imaging data to SDXC cards, while the X1 uses SDHC 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 FinePix X100 and Leica X1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the X100 and the X1 have been discontinued, but can regularly be found used on ebay. The X1 was replaced by the Leica X2, while the X100 was followed by the Fujifilm X100S. Further information on the features and operation of the X100 and X1 can be found, respectively, in the Fujifilm X100 Manual (free pdf) or the online Leica X1 Manual.

Review summary

So what is the bottom line? Is the Fujifilm X100 better than the Leica X1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Fujifilm FinePix X100:

• Broader imaging potential: Can record not only still images but also 720/30p movies.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Larger screen: Has a bigger rear LCD (2.8" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/2.8).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Longer lasting: Can take more shots (300 versus 260) on a single battery charge.
• More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 1 year after the X1).

Advantages of the Leica X1:

• More compact: Is smaller (124x60mm vs 126x75mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 139g or 31 percent) and is thus easier to take along.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More heavily discounted: Has been on the market for longer (launched in September 2009).

If the count of individual advantages (bullet points above) is taken as a guide, the X100 is the clear winner of the match-up (11 : 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 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.

How about other alternatives? Do the specifications of the Fujifilm X100 and the Leica X1 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera listing 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 X100 or the X1 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 hands-on reviews by experts 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
