Going beyond this snapshot of core features and characteristics, what are the differences between the Leica Digilux 3 and the Olympus OM-D E-M10 Mark IV? 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 physical size and weight of the Leica Digilux 3 and the Olympus E-M10 IV are illustrated 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 measures are rounded to the nearest millimeter.
The E-M10 IV 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 Olympus E-M10 IV is notably smaller (19 percent) than the Leica Digilux 3. Moreover, the E-M10 IV is substantially lighter (37 percent) than the Digilux 3. In this context, it is worth noting that neither the Digilux 3 nor the E-M10 IV 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (Digilux 3) and the Micro Four Thirds Lens Catalog (E-M10 IV). Mirrorless cameras, such as the E-M10 IV, 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 power pack in the E-M10 IV can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will naturally be influenced heavily by the price. 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 E-M10 IV was launched at a markedly lower price (by 53 percent) than the Digilux 3, which puts it into a different market segment. 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. 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. 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.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

While the two cameras under review share the same sensor size, the E-M10 IV offers a higher resolution of 20.2 megapixels, compared with 7.4 MP of the Digilux 3. This megapixels advantage translates into a 65 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M10 IV has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 5.51μm for the Digilux 3). However, it should be noted that the E-M10 IV is much more recent (by 13 years and 10 months) than the Digilux 3, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the E-M10 IV has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Olympus E-M10 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M10 IV for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 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 Olympus OM-D E-M10 Mark IV 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 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").

Many modern cameras are not only capable of taking still images, but can also record movies. The E-M10 IV indeed provides for movie recording, while the Digilux 3 does not. The highest resolution format that the E-M10 IV can use is 4K/30p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M10 IV has an electronic viewfinder (2360k 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 E-M10 IV 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 E-M10 IV has a higher magnification (0.62x 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 Olympus E-M10 IV in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M10 IV has a touchscreen, while the Digilux 3 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The E-M10 IV has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the Digilux 3 does not have a selfie-screen.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 E-M10 IV 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 Olympus E-M10 IV 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 E-M10 IV write their files to SDXC cards. The E-M10 IV supports UHS-II cards (Ultra High Speed data transfer of up to 312 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 Olympus OM-D E-M10 Mark IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M10 IV 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.
The E-M10 IV is a recent model that features in the current product line-up of Olympus. In contrast, the Digilux 3 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the Digilux 3 from Leica. Further information on the features and operation of the Digilux 3 and E-M10 IV can be found, respectively, in the Leica Digilux 3 Manual (free pdf) or the online Olympus E-M10 IV Manual.
Review summary
So what is the bottom line? Which of the two cameras – the Leica Digilux 3 or the Olympus E-M10 IV – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M10 IV is the clear winner of the contest (24 : 5 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 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 Leica Digilux 3 and the Olympus E-M10 IV 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the Digilux 3 or the E-M10 IV 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 where reviews by experts come in. 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 are only valid when referring to cameras in the same category and of the same age. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
