Going beyond this snapshot of core features and characteristics, what are the differences between the Leica Digilux 3 and the Fujifilm X-Pro1? 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 Digilux 3 and the Fujifilm X-Pro1 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 width, height and depth measures are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-Pro1 is notably smaller (10 percent) than the Leica Digilux 3. Moreover, the X-Pro1 is markedly lighter (26 percent) than the Digilux 3. In this context, it is worth noting that neither the Digilux 3 nor the X-Pro1 are weather-sealed.

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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (Digilux 3) and the Fujinon X Lens Catalog (X-Pro1). Mirrorless cameras, such as the X-Pro1, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

The price is, of course, an important factor in any camera decision. 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 Digilux 3 was launched at a somewhat lower price (by 12 percent) than the X-Pro1, which makes it more attractive for photographers on a tight budget. 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 Digilux 3 features a Four Thirds sensor and the Fujifilm X-Pro1 an APS-C sensor. The sensor area in the X-Pro1 is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the Digilux 3 has a native 4:3 aspect ratio, while the one in the X-Pro1 offers a 3:2 aspect.

With 16MP, the X-Pro1 offers a higher resolution than the Digilux 3 (7.4MP), but the X-Pro1 has smaller individual pixels (pixel pitch of 4.80μm versus 5.51μm for the Digilux 3). Yet, the X-Pro1 is a much more recent model (by 5 years and 3 months) than the Digilux 3, 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 the X-Pro1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm X-Pro1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-Pro1 for good quality output (200 dots per inch) amounts to 24.5 x 16.3 inches or 62.2 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.7 x 33.2 cm, and for excellent quality (300 dpi) 16.3 x 10.9 inches or 41.5 x 27.6 cm. The corresponding values for the Leica Digilux 3 are 15.7 x 11.8 inches or 39.8 x 29.9 cm for good quality, 12.5 x 9.4 inches or 31.9 x 23.9 cm for very good quality, and 10.5 x 7.8 inches or 26.6 x 19.9 cm for excellent quality prints.

The Leica Digilux 3 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Fujifilm X-Pro1 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Like most digital cameras, the Digilux 3 uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X-Pro1 employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 cannot only take still pictures, but also record videos. The X-Pro1 indeed provides for movie recording, while the Digilux 3 does not. The highest resolution format that the X-Pro1 can use is 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the X-Pro1 has an electronic viewfinder (1440k dots), while the Digilux 3 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 following table reports on some other key feature differences and similarities of the Leica Digilux 3, the Fujifilm X-Pro1, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The Digilux 3 has one, while the X-Pro1 does not. While the built-in flash of the Digilux 3 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the Digilux 3 and the X-Pro1 write their files to SDXC cards. The X-Pro1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the Digilux 3 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 Leica Digilux 3 and Fujifilm X-Pro1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Fujifilm X-Pro1 (unlike the Digilux 3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the Digilux 3 and the X-Pro1 have been discontinued, but can regularly be found used on ebay. The X-Pro1 was replaced by the Fujifilm X-Pro2, while the Digilux 3 does not have a direct successor. Further information on the features and operation of the Digilux 3 and X-Pro1 can be found, respectively, in the Leica Digilux 3 Manual (free pdf) or the online Fujifilm X-Pro1 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Leica Digilux 3 or the Fujifilm X-Pro1 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Leica Digilux 3:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Longer lasting: Can take more shots (750 versus 300) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More affordable: Was introduced into a lower priced segment (12 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in September 2006).

Reasons to prefer the Fujifilm X-Pro1:

• More detail: Has more megapixels (16 vs 7.4MP), which boosts linear resolution by 50%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Is equipped with a larger and more technologically advanced 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.
• Broader imaging potential: Can capture not only stills but also 1080/24p video.
• More framing info: Has an electronic viewfinder that displays shooting data.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1230k vs 207k dots).
• Faster burst: Shoots at higher frequency (6 vs 3 flaps/sec) to capture the decisive moment.
• Less heavy: Has a lower weight (by 156g or 26 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 5 years and 3 months of technical progress since the Digilux 3 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the X-Pro1 is the clear winner of the contest (16 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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 Leica Digilux 3 and the Fujifilm X-Pro1 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 incomplete and does no justice, for example, to the way the Digilux 3 or the X-Pro1 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
