Going beyond this snapshot of core features and characteristics, what are the differences between the Leica Digilux 3 and the Panasonic Lumix DMC-LX100? 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 Leica Digilux 3 and the Panasonic LX100. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The LX100 can be obtained in two different colors (black, silver), while the Digilux 3 is only available in silver.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic LX100 is considerably smaller (40 percent) than the Leica Digilux 3. In this context, it is worth noting that neither the Digilux 3 nor the LX100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX100 has a lens built in, whereas the Digilux 3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the Digilux 3 and their specifications in the Four Thirds Lens Catalog.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 LX100 was launched at a lower price than the Digilux 3, despite having a lens built in. 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.

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. 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. 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 a Four Thirds sensor, but their sensors differ slightly in size. The sensor area in the LX100 is 18 percent smaller. As a result of these sensor size differences, the cameras have format factors, respectively, of 2.0 (Digilux 3) and 2.2. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. The LX100 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.

Despite having a smaller sensor, the LX100 offers a higher resolution of 12.7 megapixels, compared with 7.4 MP of the Digilux 3. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.82μm versus 5.51μm for the Digilux 3). However, it should be noted that the LX100 is much more recent (by 8 years) than the Digilux 3, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Panasonic LX100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the LX100 for good quality output (200 dots per inch) amounts to 20.6 x 15.4 inches or 52.2 x 39.2 cm, for very good quality (250 dpi) 16.4 x 12.4 inches or 41.8 x 31.4 cm, and for excellent quality (300 dpi) 13.7 x 10.3 inches or 34.8 x 26.1 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 Panasonic Lumix DMC-LX100 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

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.

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 LX100 indeed provides for movie recording, while the Digilux 3 does not. The highest resolution format that the LX100 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the LX100 has an electronic viewfinder (2764k 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 viewfinder in the LX100 offers a wider field of view (100%) than the one in the Digilux 3 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the LX100 has a higher magnification (0.70x vs 0.47x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Leica Digilux 3 and Panasonic LX100 in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The Digilux 3 has one, while the LX100 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.

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 LX100 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 Panasonic LX100 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 Digilux 3 and the LX100 write their files to SDXC cards. The LX100 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 Panasonic Lumix DMC-LX100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the LX100 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the Digilux 3 does not provide wifi capability.

Both the Digilux 3 and the LX100 have been discontinued, but can regularly be found used on ebay. The LX100 was replaced by the Panasonic LX100 II, while the Digilux 3 does not have a direct successor. Further information on the features and operation of the Digilux 3 and LX100 can be found, respectively, in the Leica Digilux 3 Manual (free pdf) or the online Panasonic LX100 Manual.

Review summary

So what conclusions can be drawn? Is the Leica Digilux 3 better than the Panasonic LX100 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Leica Digilux 3:

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.

If the number of relative strengths (bullet points above) is taken as a guide, the LX100 is the clear winner of the contest (20 : 6 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 Panasonic LX100 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 LX100 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
