Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 7 and the Olympus OM-D E-M10 Mark III? 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 D-LUX 7 and the Olympus E-M10 III 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 III can be obtained in two different colors (black, silver), while the D-LUX 7 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 III is notably larger (35 percent) than the Leica D-LUX 7. In this context, it is worth noting that neither the D-LUX 7 nor the E-M10 III are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the D-LUX 7 has a lens built in, whereas the E-M10 III 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 E-M10 III and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the D-LUX 7 gets 300 shots out of its Leica BP-DC15 battery, while the E-M10 III can take 330 images on a single charge of its Olympus BLS-50 power pack. The power pack in the D-LUX 7 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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

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. 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. 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a Four Thirds sensor, but their sensors differ slightly in size. The sensor area in the E-M10 III is 22 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 2.2 (D-LUX 7) and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. The D-LUX 7 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 Leica D-LUX 7 offers a higher resolution of 16.8 megapixels, compared with 15.9 MP of the Olympus E-M10 III. 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 3.32μm versus 3.76μm for the E-M10 III). However, it should be noted that the D-LUX 7 is a somewhat more recent model (by 1 year and 2 months) than the E-M10 III, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. 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 Leica D-LUX 7 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The Olympus OM-D E-M10 Mark III offers exactly the same ISO settings.

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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set 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 E-M10 III has one, while the D-LUX 7 does not. While the built-in flash of the E-M10 III 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, both cameras under consideration feature an 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 Leica D-LUX 7 and the Olympus E-M10 III both have 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 D-LUX 7 and the E-M10 III write their files to SDXC cards. The E-M10 III supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the D-LUX 7 can use UHS-I cards (up to 104 MB/s).

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 D-LUX 7 and Olympus OM-D E-M10 Mark III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D-LUX 7 and the E-M10 III have been discontinued, but can regularly be found used on ebay. The E-M10 III was replaced by the Olympus E-M10 IV, while the D-LUX 7 does not have a direct successor. Further information on the features and operation of the D-LUX 7 and E-M10 III can be found, respectively, in the Leica D-LUX 7 Manual (free pdf) or the online Olympus E-M10 III Manual.

Review summary

So how do things add up? Is there a clear favorite between the Leica D-LUX 7 and the Olympus E-M10 III? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Leica D-LUX 7:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• More detailed viewfinder: Has higher resolution electronic viewfinder (2764k vs 2360k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.62x).
• More detailed LCD: Has a higher resolution rear screen (1240k vs 1040k dots).
• Faster burst: Shoots at higher frequency (11 vs 8.6 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the E-M10 III requires a separate lens.
• More compact: Is smaller (115x66mm vs 122x84mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-M10 III).
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More modern: Is somewhat more recent (announced 1 year and 2 months after the E-M10 III).

Reasons to prefer the Olympus OM-D E-M10 Mark III:

• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More heavily discounted: Has been on the market for longer (launched in August 2017).

If the count of relative strengths (bullet points above) is taken as a measure, the D-LUX 7 emerges as the winner of the contest (12 : 9 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 D-LUX 7 and the Olympus E-M10 III place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 says little about, for example, the shooting experience and imaging performance of the D-LUX 7 and the E-M10 III in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
